Shadow Banking System And Repo Market Finance Essay - Free Essay Example

The shadow banking system played a crucial role in the 2007-2009 financial crisis that, in which one of the most important role is the creation of systemic risk. Since repurchase agreements are the major component of the shadow banking system, it is necessary to focus on the role of repo in the shadow banking system as well as in the 2007-2009 financial crisis, then discuss for effective regulation on repo market. In addition, for the repo markets systemic nature and structural weaknesses, regulatory exercise on repo market should focus more on systemic risk of financial institutions, rather than individual, as the current regulations. Key Words: shadow banking system, repurchase agreement, systemic risk, regulation. Acknowledgements Table of Content Chapter 1. Introduction The shadow banking system played a critical role in the 2007-2009 financial crisis. The FSB (2011b) report has defined shadow banking as credit intermediation which occurs outside or partially outsi de the banking system, but which involves leverage and maturity transformation, and the shadow banking system as the system of credit intermediation that involves entities and activities outside the regular banking system. It provides a cheaper and more efficient way for corporations to meet their needs on funding, and was emerge as a complement to regular banking. However, the financial crisis shown that the shadow banking system can also create a number of risks, in which the most important one is systemic risk. A repurchase agreement is a financial contract that market participants used it as a financing method to meet short and long term liquidity needs, in which one participant borrows cash from the other by pledging a financial security as collateral. In U.S. repo market, a series of regulatory changes in the 1980s made the repo market an attractive source of short-term financing for primary dealers to finance their positions in the debt of the U.S. government, federal agen cies, corporations, and federal agency mortgage-backed securities. Moreover, another significant change in 2005 makes repo transactions eligible for bankruptcy safe harbor protection based on any stock, bond, or security. In addition, the rapid growth of money holding by institutional investors, pension funds, mutual funds, states and municipalities, and non-financial firms is another main driver for increasing use of repos. Unfortunately, there is no official data of the overall size of the repo market in U.S.. Since repos are the major component of the shadow banking system, and shadow banking is seen to rely on wholesale funding such as repo as the deposits issued by traditional banks, and even seen as more dependent on these sources of funding than traditional banks are on deposits, it is necessary to focus on the role of repo in the shadow banking system as well as in the 2007-2009 financial crisis, and discuss the effective regulation on repo market. 1.1 Aim and Research Objectives The primary aim of this research is: Shadow Banking System and Repo Market during 2007-2009 Financial Crisis: the Implications for Repo Regulation In particular, the research will address the following research aspects: Study the classical researches on shadow banking system, repo market and regulations. Discuss the critical role of repo in 2007-2009 financial crisis and the necessity of repo regulation. Summarize and discuss recent financial regulation, and give the implications for the future. 1.2 The Structures of Dissertation There are 6 chapters in this dissertation, the first chapter is the introduction which introduces the reasons for writing, research aim and objectives. The second chapter briefly introduce the background of the dissertation. First give a definition on shadow banking system, discuss its role in financial system, and point out its differences compared to traditional banking system. Then provide the definition of re purchase agreement, explaining how it works, outlining a profile of the U.S. repo market, and describing how it came to play such an important role in the shadow banking system. The third chapter overview classic literatures related to the shadow banking system, repo market and financial regulations. The fourth chapter using data to help understand the changes in financial crisis, and then discuss the critical role that repos play in the current financial crisis. The fifth chapter focus on repo regulation, which overview the regulatory framework of repo market, summarize current regulatory exercises in several countries, and then articulate the implications for future repo market regulation. The last chapter is the conclusion of the research, which summary the main ideas in the paper. Chapter 2. Background of Dissertation 2.1 Shadow Banking System FSB (2011a) mentions that the emergence of the term shadow banking system reflected a recognition of the increased i mportance of entities and activities structured outside the regular banking system that perform bank-like functions. The recent financial crisis demonstrated that shadow banking is highly interrelated with the regular banking system and can have an significant impact on financial stability. In the later report, FSB (2011b) defined shadow banking as credit intermediation which occurs outside or partially outside the banking system, but which involves leverage and maturity transformation, and the shadow banking system as the system of credit intermediation that involves entities and activities outside the regular banking system. The traditional banking system based on making and holding loans with insured savings as the main source of funds, it borrowing short-term from other banks and lending long-term to the retail consumer. The shadow banking system based on the business of packaging and reselling loans, it provides a cheaper and more efficient way for corporations to meet th eir needs on short-term funding, in which repos and asset-backed commercial paper (ABCP) are the main source of funds. These banks provide credit both directly and indirectly through three different processes of financial transformation: Credit transformation, which means they enhance the credit quality to offer a range of seniority and duration, and a corresponding range of risk and return, from short-term AAA down to equity; Maturity transformation, by which they finance long-term assets with short-term liabilities, it makes the term of their liabilities much shorter than their assets, and exposes short-term investors to market liquidity and duration risks; Liquidity transformation, by which they fund illiquid assets with liquid liabilities, it causes the same result as maturity transformation through different techniques. According to one measure of the size of the shadow banking system from FSB (2011), it grew rapidly before the financial crisis, from an estimated $2 7 trillion in 2002 to $60 trillion in 2007, and remained at around the same level in 2010. Gorton and Metrick (2010a) argue that the force from both supply and demand side cause the rapid development of shadow banking system before the current crisis: a series of changes in innovations and regulations eroded the banks competitive advantage; and demand for collateral for financial transactions of bank promote the development of securitization and increase the use of repos as a money-like instrument. On the one hand, it should be recognised that intermediating credit through shadow banking can offer advantages to the financial system. First, shadow banking system provide an alternative source of funding for market participants to bank deposits. Second, since some non-bank entities increased specialization, it provide more efficiently credit resource to meet the specific needs in the economy and reduce the cost the investors. Third, it constitute an alternative source to diversify r isk other than traditional banking system. On the other hand, however, as the financial crisis has shown, the shadow banking system can also create a number of risks, in which the most important one is systemic risk. First, shadow banking business exposed to the similar risks as traditional banks, it financed by short-term deposit-like funding of non-bank entities, which my lead to runs in the market if confidence is lost. Second, the operation of non-deposit sources of collateral funding in shadow banking can be highly leveraged without being limited by regulator, especially when asset prices are rise and haircuts on secured financing are low. Highly leveraged transactions can increase the fragility of the financial system and become a source of systemic risk. Third, the risks in the shadow banking system can easily transmitted to the regular banking system since shadow banking businesses are often closely linked to the traditional banking sector. Which means that any failures i n shadow banking can lead to important contagion due to the fact that banks often take part in the shadow banking credit intermediation chain or even provide support to the shadow banking entities. In addition, shadow banking system operations provide tools that banks can use it to avoid regulation or supervision applied to traditional bank system. Banks can break the traditional credit intermediation process under legally independent structures dealing with each other. As well known, the operations that banks circumventing capital and accounting rules, transferring risks out the control of banking regulation is the main cause of the recent crisis. 2.2 The Repurchase Agreement (Repo) Market 2.2.1 The Repurchase Agreement (Repo) The most important component in shadow banking is securitized debt, such as U.S. Treasuries, commercial paper, mortgage-backed securities (MBSs), equities, and so on. Acharya and ÃÆ'Æ’-ncà ¼ (2010) mention that, by the fourth quarter of 2009, th e amount of outstanding securitized debt in the United States totaled $11.6 trillion, about one-third of the entire U.S. debt market, and much of this securitized debt is in the form of repurchase agreements. As mentioned before, shadow banking is seen to rely on wholesale funding such as repo as the deposits issued by traditional banks, and even seen as more dependent on these sources of funding than traditional banks are on deposits. A repurchase agreement is a financial contract that market participants used it as a financing method to meet short and long term liquidity needs, in which one participant borrows cash from the other by pledging a financial security as collateral. It also known as a sale and repurchase agreement for a two part transaction, originally the bank or borrower, and the depositor or lender. In case that repo is negotiated and executed privately between a borrower and a lender, it is referred to as a bilateral agreement. And when both participants to a rep o share a common custodian to hold collateral and to transfer cash, the arrangement is referred to as a tri-party repo. The depositor deposits money and earns interest, whereas the bank provides bonds as collateral to back the deposit in exchange for the cash. Regulatory changes in the 1980s made the repo market an attractive source of short-term, often overnight, financing for primary dealers to finance their positions in the debt of the U.S. government, federal agencies, corporations, and federal agency mortgage-backed securities. Later, it also became a funding source for investors to lend and invest in relatively illiquid mortgage-backed securities. When a repo transaction is agreed, cash will exchange for collateral on both the settlement and the maturity. The sale price for the establishment of securities equals to the amount of cash lent to the borrower, and the repurchase price is equivalent to the sale price plus interest charged by lender. Typically, the loan amount is equivalent to the market value of the collateral minus a haircut, in which the haircut is a percentage that calculated to protect the lender in the case of default by the borrower. Figure 2.1 shows the cash exchanges in an overnight bilateral repo that settles on the day after the trade and matures on the day after settlement, and Figure 2.2 illustrates the role of a tri-party agent in holding the borrowers collateral and transferring the lenders cash. Repo is an over-the-counter (OTC) contract that shares many key features with derivatives, such as the reliance on its counterparts to meet obligations over time. Similar as all OTC products, the life cycle of repo contains several standard processes: documentation, execution, clearing, settlement, and custody. Figure 2.3 shows the life cycle of repo. The step of clearing is the match of trade notices generated by the two participants and the initiation of settlement instructions for the movement of cash and securities. Cl earing happens several times during the life cycle of a trade: dealers match trades between themselves and their clients, and depositories match the resulting settlement instructions. Settlement of repo is the exchange of cash and collateral. Custody is the maintenance of the cash and collateral in two separate accounts for both the lender and the borrower, which are held by broker-dealers themselves, by custody banks representing either party to the transaction, or by a single bank serving as custodian for both parties simultaneously. 2.2.2 Repo Market in the U.S. In 1917, the repurchase agreements were first introduced to the U.S. financial market by the Federal Reserve. As Acharya and ÃÆ'Æ’-ncà ¼ (2010) mention, the Fed used repos secured with bankers acceptances to extend credit to dealers to encourage the development of a liquid secondary market for acceptances. Early repos in the U.S. had two distinguishing features. First, accrued interest was excluded from the price of the repo securities. Second, even though the creditor could sell or deliver the repo securities to settle a prior sale at prices that included the accrued interest during the term of the repo, ownership of the repo securities rested with the debtor. Figure 2.4 lists the main changes in the U.S. repo market history, the last significant change before the current crisis is that Congress enacted the Bankruptcy Abuse Prevention and Consumer Protection Act of 2005 (BAPCPA), which expanded the definition of repurchase agreements to include mortgage loans, mortgage-related securities, and interest from mortgage loans or mortgage-related securities, which make repo transactions eligible for bankruptcy safe harbor protection based on any stock, bond, or other security . In the U.S. repo market, loans are mostly extended overnight, which constitute about half of all repo transactions, and most of them are open, which means that they roll over automatically until either party ch ooses to exit. Other repo transactions called term repos, have terms longer than one day but shorter than one year, while most maturity of them three months or less. Participants in the repo market include commercial banks, investment banks, hedge funds, mutual funds, pension funds, money market funds, municipalities, corporations, and other owners of large amounts of idle cash, as well as the Fed and primary securities dealers. The Fed participates in the repo market mostly to implement its monetary policy, while primary securities dealers participate mainly to finance their market-making and risk management activities. Owners of large amounts of cash in the repo market mainly engage for two reasons: First, get better interest rates in the repo market compared with deposits at commercial banks. Second, for insurance purposes. Large deposits at commercial banks are not insured, whereas deposits at repo banks are secured by debt used as collateral. The rapid growth of money hol ding by institutional investors, pension funds, mutual funds, states and municipalities, and non-financial firms is one of the main drivers of increasing use of repos. They are seeking for a safe investment which can earn interest and simultaneously have strong liquidity. Under the U.S. Bankruptcy Code, especially since the change in 2005, repos have a special status: repo contract allows either participant to enforce the termination provisions of the agreement unilaterally if a bankruptcy filing by the other participant. Figure 2.5 shows the institutional investors financial assets in the United State from 1980 to 2008. Unfortunately, there is no official statistics of the overall size of the repo market in US, the Fed only counted the repo contracts that completed by the primary security dealers trade with the Fed. Figure 2.6 indicates annual average of Daily financing by U.S. government primary dealers from 1996 to 2011, and it can be seen that there is an exponential growth i n repo market. Hà ¶rdahl and King (2008) report that repo markets doubled in size from 2002 to 2007, the paper indicate that with gross amounts outstanding at year-end 2007 of roughly $10 trillion in each of the US and euro repo markets, and another $1 trillion in the UK repo market. They also point out that the U.S. repo market exceeded $10 trillion in mid-2008, including double counting both repo and reverse repo in the same transaction. Gorton (2010) illustrate that the size of repo market in US is likely to be about $12 trillion as of 2009, compared with the total assets in the U.S. banking system of $10 trillion. In addition, the tri-party repo is predominantly part in the US repo market, anecdotal evidence suggests that tri-party repo activity may account for between 65% and 80% of the overall US repo market. Figure 2.7 shows the growth of tri-party repo transactions from May 2002 to May 2010. The value of securities financed by tri-party repos grow smoothly since 2002, reached the peak to about $2.8 trillion in early 2008, then the size of the market has declined notably to $1.7 trillion during first-quarter in 2010. Chapter 3. Literature Review The term shadow banking system was first coined by former Pacific Investment Management Company (PIMCO) executive Paul McCulley at Federal Reserve Bank of Kansas Citys Economic Symposium in Jackson Hole Wyoming in 2007. McCulley (2010) said that the shadow banking system appeared with the development of money market funds in the 1970s, the money market accounts function similar as bank deposits, but money market funds not regulated as banks. Gertler and Boyd (1993) and Corrigan (2000) are early discussions of the role of commercial banks and the market based financial system in financial intermediation. Paul Krugman (2008) of the New York Times trace the cause of the economic meltdown to a run on shadow banks when credit dried up. He argued that the shadow banking system rely on complex financial design, avoid the conventional financial regulation and take part in more commercial banking business. Because of not regulated, shadow banks are easier to expand business areas than traditional banks, the financial crisis leads people to transfer their money from the shadow banking system to government bonds, suddenly the shadow Banks liquidity exhaustion. 3.1 Literature on Shadow Banking System After the panic of 2007, there are a number of academic studies focus on the shadow banking system, and point out that the shadow banking system is at the heart of the credit crisis. Pozsar (2008) cataloguizes different types of shadow banks and describes the asset and funding flows within the shadow banking system. The paper clearly presents how the collateralized debt obligations (CDOs) changed from tools to manage credit risk to a source of credit risk. Adrian and Shin (2009) focus on the role of security brokers and dealers in the shadow banking system, and discuss the implica tions for financial regulation. The paper illustrates that securitization was initially intended to be a way to transfer credit risk to something better able to absorb losses, but instead it increased the fragility of the financial system. It allows banks and other intermediaries to leverage up by buying each others securities. They point out that it is important to prevent excessive leverage and maturity mismatch, which can undermine the stability of entire financial system. Pozsar, Adrian, Ashcraft, and Boesky (2010) provide a overview of shadow banking institutions and activities, focus on funding flows in a somewhat mechanical manner. The paper outline the economic role of shadow banking and show that there is a deep connection between shadow banking system and traditional banking system. The authors expect the shadow banking to be a significant part in the financial system in the future, but in a different form. Gorton and Metrick (2010a) present a good description of the shadow banking system and discuss its risks to financial stability. The analysis focus on three major institutions: money-market mutual funds (MMMFs), securitization and repurchase agreements (repos). They argue that the change that makes repo a bankruptcy safe harbor was crucial to the growth and efficiency of shadow banking, regulators can make use of the admittance to this bankruptcy safe harbor as the breach to enforce new regulations. Gennaioli, Shleifer and Vishny (2011) develop a model of shadow banking where intermediaries originate, securitize and trade loans, financed externally with riskless debt. As a result, maturity transformation and leverage are excessive, and lead to credit booms and busts when investors and intermediaries neglect tail risks. Therefore, the paper argued that regulators should continuously monitor intermediaries exposures and financial innovations and intervene when necessary. 3.2 Literature on Repurchase Agreements (Repo) There are increas ing number of literatures on markets for repurchase agreements (repo) since the panic of 2007 broke out. Before that, studies on repo mainly focus on the asset pricing field, e.g. Duffie (1996) and Buraschi and Menini (2002). After the 2007 financial crisis, the researchers started to discuss the role of repo in shadow banking system, and its contribution to recent financial crisis. Most of the researches are based on the evidence of the U.S. repo market. Many theoretical studies have shown that pro-cyclical margins and haircuts have strong negative impact on the stability of financial markets. Brunnermeier and Pederson (2009) develop a model where margins can increase in illiquidity given uncertainty over the nature of price shocks. Once the speculators are subject to capital constraints, they will reduce their positions and market liquidity fall, which will then lead to higher margins and a so-called liquidity spiral. They argued that regulators should improve market liquidity by boosting speculator funding conditions during a liquidity crisis. Jurek and Stafford (2010) provide financing terms in collateralized lending markets with a theoretical model. The paper shows that securities which have quickly declining recovery values are financed at higher haircuts, will respond much more strongly to market fluctuations. They argue that the risk profile of the underlying collateral alone can explain why the repo haircuts shift massively during the recent financial crisis. Acharya, Gale and Yorulmazer (2011) present a model of market freezes and haircuts in secured borrowing, which explain a main feature of the crisis of 2007-2009: a sudden freeze in the market for short-term and asset-backed financing. The model contains three essential features: the term of debts is much shorter than the assets and needs to rolled over frequently; if the borrower default the contract, the collateral will be sold by the creditors and there is a small liquidation cost; and a sig nificant part of potential buyers of the collateral also relies on short-term debt finance. Under these conditions, the debt capacity of the assets can be much less than the fundamental value, and in fact, equal the minimum possible value of the asset. The paper argued that it is true even if the fundamental value of the assets is currently high. In particular, a small change in the fundamental value of the assets can be associated with a sudden collapse in the debt capacity. Other papers on this topic include Valderrama (2010), Rytchkov (2009), Geanakoplos (2010). Predictably, a great number of empirical literatures based on evidence from the US repo market have turned up to confirm the pro-cyclicality of margins and haircuts. The conclusion from these empirical studies strongly show that changes in margins and haircuts has a signally negative effect on financial system. Adrian and Shin (2010) showed that marked-to-market leverage is strongly procyclical, repo transactions ha ve accounted for most of the pro-cyclical adjustment of the leverage of investment banks. In this paper, they argued that aggregate liquidity can be understood as the rate of growth of the aggregate financial sector balance sheet. Financial intermediaries balance sheets generally become stronger when asset prices increase, their leverage tends to be too low, and then they hold surplus capital. In this case, the intermediaries will attempt to find ways to employ their surplus capital. And for such surplus capacity to be utilized, they must expand their balance sheets, which means that they should take on more short-term debt on the liability side and search for potential borrowers on the asset side. From the evidence of repo market in the U.S., it can be seen that when balance sheets are expanding fast enough, borrowers are granted credit even they do not have the means to repay, since the urge to employ surplus capital is so intense. They point out that this is the fundamental cause for the subsequent decline in the credit cycle. Gorton and Metrick (2010b) present direct evidence on the haircuts in the repo market and illustrate that withdrawals from securitized banks is the main cause of increase in repo haircuts, which means that it is a bank run. The paper said that when all investors involve in the run and the haircuts rise high enough, the securitized banking system cannot finance itself and is forced to sell assets. These changes in the constraints on funding liquidity can have a fast effect on asset prices and market dynamics. As a result, the assets become information sensitive and the liquidity dries up, and finally the system is insolvent. Gorton and Metrick (2011) argued that one of the major cause of the 2007-2009 financial crisis was changes in repo haircuts.The paper study a segment of the bilateral repo market and use a novel data set that includes credit spreads for hundreds of securitized bonds to trace the path of crisis from sub-prime- housing related assets into markets that had no connection to housing. They find that changes in the LIB-OIS spread, a proxy for counter-party risk, was strongly correlated with changes in credit spreads and repo rates for securitized bonds, which implied higher uncertainty about bank solvency and lower values for repo collateral. Moreover, they draw a figure showing the haircuts index, which can be seen as an average haircut for collateral used in repo transactions but not including U.S. Treasury securities, In the US repo market, average haircut rising from zero before July 2007 to nearly 50 percent at the peak of the financial crisis in late 2008. With decreasing asset values and increasing haircuts, the U.S. banking system was finally insolvent for the first time since the Great Depression. However, Richard Comotto (2012) argued that there is a serious flaw in this haircut index, as well as the thesis that much of the crisis was driven by run on repo. The paper point out that Gorton and Metrick (2011)s data based their conclusions was only for collateral in the form of structured securities (ABS, RMBS, CMBS, CLO and CDO). Moreover, the paper claim that Gorton and Metrick (2011) offer no data on US Treasuries, which constitutes the largest pool of repo collateral in the US, and ignore the tri-party segment of the repo market, which may have accounted for 50-60% of outstanding U.S. repo and is largely collateralized by U.S. Treasuries, Agencies and MBS, for which haircuts are much lower and asset values were not impacted by the crisis to anything like the degree as structured securities. The paper also indicate that the Fed sponsored Task Force on Tri-party Repo Infrastructure (2009) reported that the available data suggested that haircuts in the tri-party repo market did not change much during the 2007-2009. In conclusion, Richard Comotto (2012) thought that Gorton and Metrick (2011) are unwise to assume that repo funding is by virtue of the dynamics of haircuts is an inherently unstable source of funding without sufficient empirical data. Copeland, Martin and Walker (2011) find that there are significant differences between haircut changes in bilateral and tri-party segment of the repo market. During the 2007-2009 financial crisis, haircuts and funding in the bilateral repo market changed dramatically which is similar with the result of Gorton and Metrick (2011)s work. However, haircuts in the tri-party repo market did not change much, and that funding was very stable for dealers, and the only exception is Lehman Brothers, whose tri-party repo book decreased sharply in the days leading up to its bankruptcy. The author provide three possible explanations as to why haircuts in the tri-party repo market almost keep unchanged. First one is that some cash investors prefer to withdraw funding rather than take possession of the collateral when they think a dealer is not creditworthy. Secondly, since money funds are very intolerant of liquidity and credit risk, major categories of tri-party repo investors have to worry about withdrawal pressures from their own investors. Thirdly, due to tri-party repos were mainly overnight and the clearing bank would unwind repos every morning, cash investors may feel that they can always pull away from troubled dealer, which makes the management of haircuts less important. Since tri-party repo market and the bilateral repo market were both at the heart of the current financial crisis, to recognise the different use of haircuts across these two repo markets is important to regulators in considering policies designed to prevent runs on securities dealers. A further study from Martin, Skeie and von Thadden (2011), develop a dynamic equilibrium model to study how the fragility of short-term funding markets depends upon the particular microstructures, liquidity, and collateral arrangements that may lead to runs at various types of financial institutions. The paper shows that mark et microstructure can explain the different changes of haircuts between bilateral and tri-party repo markets. The haircut for each collateral class is included in the custodial undertaking agreement between the three parties and takes much more time to change than bilateral contracts, which make the tri-party repo market more susceptible to runs. The model can actually explain why haircuts may not adjust sufficiently to protect the investors in case of Lehman Brothers. Although several studies believe that the run on the repo market play a crucial role during the financial crisis, some empirical papers argue that the impact of repo contraction on the shadow banking system is relatively limited. For example, Krishnamurthy, Nagel and Orlov (2012) measure the repo funding extended by money market funds (MMF) and securities lenders to the shadow banking system, including quantities, haircuts, and repo rates by type of underlying collateral. They suggest that repo only played a very s mall role in funding private sector assets prior to the crisis, only 3% of outstanding non-Agency mortgage-backed securities (MBS) and asset-backed(ABS) securities was financed by repos from MMFs or securities lenders, and 22% was financed by asset-backed commercial paper (ABCP). However, they also find that the contraction in repo particularly have systematical impact on key dealer banks with large exposures to private sector securities, which then had knock-on effects on security markets. 3.3 Literature on Repo Market Regulation Gai, Haldane and Kapadia (2011) develop a network model of interbank lending in which unsecured claims, repo activity and shocks to the haircuts applied to collateral assume center stage. The model shows that how the complexity and concentration in financial system may amplify its fragility. The analysis not only points out that minimum margin requirements can be used as a macro-prudential tool in regulation, it also suggests that how a range of poli cy measures including liquidity regulation and capital surcharges for systemically important financial institutions could make the financial system more resilient. Goodhart, Charles, Kashyap, Tsmocos and Varoulavis (2011) introduce a model that includes both a banking system and a shadow banking system that each help households finance their expenditures, and explore how different types of financial regulation could combat many of the phenomena that were observed in the financial crisis of 2007 to 2009. The paper analyses the effects of increasing margin requirements on repo transactions, and show that margin restrictions may partially constrain risk taking and raise the cost of mortgage borrowing. Gorton and Metrick (2010b) suggest that repos should be regulated because they are, in effect, new forms of banking, it is similar to bank deposits but have the same vulnerabilities as bank-created money. The authors proposals are aimed to create a sufficient amount of high quality collateral which can safely be used in repo transactions. Acharya and ÃÆ'Æ’-ncà ¼ (2012) point out one of the regulatory failures behind the recent financial crisis started in 2007 has been that the regulatory exercise focus on individual, rather than systemic, risk of financial institutions. Therefore, they provide a set of resolution mechanisms which is not only capable of addressing the issues of inducing market discipline and mitigating moral hazard, but also capable of addressing the systemic risk associated with the systemically important assets and liabilities (SIALs). Specifically, in order to control the risk of the run on repo market, the authors propose to create a Repo Resolution Authority (RRA) in jurisdictions with significant repo activities, which can address the externality of systemic risk of repo contracts on risky and potentially illiquid collaterals. Chapter 4. Repo in 2007-2009 Financial Crisis 4.1 The Crisis of 2007-2009 Due to the fact that t he majority of leveraged positions in shadow banking was based on repo financing, it effectively observed that a run on repos play a significant role in the financial crisis. Gorton and Metrick (2010) use two main variables to help review the timeline of the crisis: the ABX index, and LIB-OIS. The ABX index provides publicly observable market that prices sub-prime risk, can be seen as a proxy for fundamentals in the sub-prime mortgage market. The LIB-OIS, which is the spread between the three-month London Interbank Offered Rate (LIBOR) and the three-month overnight index swap (OIS) rate, can be seen as a proxy for counter-party risk in repo transactions. Figure 4.1 shows the ABX and LIB-OIS spreads, in which the ABX spread is the CDS spread on the BBB-rated ABX tranche of the first vintage of the ABX in 2006. According to the ABX index in figure, the sub-prime market start to deteriorate since the beginning of 2007, which had a direct impact on banks whoes balance sheets had l ots of securitized assets and pre-securitized mortgages. Creditors started to ask the two Bear Stearns funds to provide more collateral to back the repos, and when the funds unable to meet the calls, creditors led by Merrill Lynch threatened to declare the funds in default of repos and to seize the investments. In fact, according to Acharya et al. (2009), Merrill seized $850 million of the CDOs and tried to auction them on June 19, 2007. However, when Merrill was only able to sell approximately $100 million worth of CDOs, sub-prime assets illiquid nature and the declining value emerged. The rapid increase of the ABX spread during July 2007 appears to be a response of the sub-prime market to this run on the shadow banks in the repo market. The importance of the exemption of repos from the application of automatic stay becomes to emerge. The Bear Stearns funds can have filed for bankruptcy and avoid the forced fire sale of their assets since their repo securities was subject to aut omatic stay, and the sub-prime mortgage decline became systemic eventually. After keeping unchanged in the first 6 months in 2007, LIB-OIS first signals danger with the first major jump in August, for the real deterioration in bank balance sheets in the interbank market. In period during July to September LIB-OIS reached and past its historical record 3 times, which is also the period that the initial shock for a wide range of the securitization markets, particularly in high-grade parts that commonly used as collateral in the repo market.In early August 2007, a run ensued on the assets of three structured investment vehicles (SIVs) of BNP Paribas. On August 9, BNP Paribas suspended redemptions from these SIVs. BNP Paribass SIVs were bankruptcy-remote entities financing their sub-prime holdings through the issuance of ABCPs that had essentially lost their liquidity and become non-tradable. The announcement of the suspension of redemptions by BNP Paribas gave rise to counter-party risk concerns and caused the ABCP market to freeze, and This freeze coincided in the LIB-OIS spread. Fears of counter-party risk spread through markets, all short-term debt markets-including the repo market-froze, only to open after central banks injected massive amounts of liquidity into the system. The LIB-OIS spread remained in a historically high until September 2008, when the events at Fannie Mae, Freddie Mac, Lehman, and AIG cause a rapid regression in interbank markets and sustained increase in the LIB-OIS until the end of 2008. 4.2 Repo Haircuts A haircut of repo is a percentage discount deducted from the market value of a security which is being offered as a collateral in a repo in order to calculate the purchase price. The formula for a haircut is as follow: It counts to addresses the risk that if the depositor of the bond in repo must sell a bond in the market to get the withdrawal, the trader to whom the bond is sold may be better informed and resulting in a loss, which means that the price may not adjust to address this risk. In this case, a haircut tranching the collateral to recreate an information insensitive security and thereby improve its liquidity. Gorton and Metrick (2010) suggest that the increasing haircuts in the interdealer repo market may be seen as a run on shadow banks, it tantamount to a withdrawal from the issuing bank. Figure 4.2 shows the haircuts for the non-sub-prime-related group, sub-prime-related groups, and the average of all the categories from 2007 to 2009. The data Gorton and Metrick (2010) examine are the interdealer repo haircuts for the following asset classes ¼Ãƒâ€¦Ã‚ ¡(1) A-AAA ABS (auto/credit cards/student loans); (2) AA-AAA RMBS/CMBS; (3) below-A RMBS/CMBS; (4) AA-AAA CLO; (5) unpriced ABS/MBS/all sub-prime; (6) AA-AAA CDOs; (7) unpriced CLOs/ CDOs. Of these classes, (1) through (4) are not sub-prime related since they do not contain sub-prime mortgages. The RMBS in categories (2) and (3) a re prime mortgages, not sub-prime. Categories (5) through (7) are either directly sub-prime or contain sub-prime mortgages. in particular, CDOs contain some sub-prime mortgages. Gorton and Metrick (2010) use all seven categories to construct an equally weighted average repo haircut index for structured bonds. Figure 4.2 illustrates that in the period of 2007 to 2009, the repo haircuts increased from zero in early 2007 to nearly 50 percent in late 2008 on average. Haircuts were higher on sub-prime-related asset classes, it eventually went to 100 percent haircuts, which means these assets were not acceptable in repo as collateral, whereas the non-sub-prime-related asset classes reached a peak at 20 percent. In order to help understand the impact of run on repo, for instance, take total size of the repo market to be $10 trillion. Then, if the average haircut goes from zero to 20 percent during the crisis, which means that the securitized banking system must rise $2 trillion from ot her sources to fund its assets. In this case, the only available way for banks to make up the difference was sale the asset, which caused a further decline in the prices of these asset classes, making them less usable as collateral, then further sales, and so on. Moreover, Figure 4.2 also shows a loss of confidence through the haircut growth in the non-sub-prime-related group even though it had nothing to do with sub-prime mortgages. It is worth noticing that Gorton and Metrick (2010)s data ignore the tri-party segment of the repo market, and according to the Task Force on Tri-party Repo Infrastructure White Paper (2010), the available data suggested that haircuts in the tri-party repo market almost remain unchanged during 2007 and 2009. However, it does not mean tri-party repo had nothing to do with the crisis. FRBNY White Paper (2010) claims that (a)t several points during the financial crisis of 2007-2009, the tri-party repo market took on particular importance in relation to the failures and near-failures of Countrywide Securities, Bear Stearns, and Lehman Brothers. The potential for the tri-party repo market to cease functioning, with impacts to securities firms, money market mutual funds, major banks involved in payment and settlements globally, and even to the liquidity of the U.S. Treasury and Agency securities, has been cited by policy makers as a key concern behind aggressive interventions to contain the financial crisis. 4.3 The Transparency of Repo Security financing market is complicated, evolved rapidly and sometime can be opaquely for some market participants and regulators. The transparency may, as well, be lacking due to the bilateral nature of securities financing transactions. During the financial crisis, the lack of transparency is embodied in several levels: Market data on macro level: previous to the current crisis, some authorities faced difficulties in valuating and supervising the risks on certain angles of the markets. The re are only some available data from data vendors that collect information from intermediaries for commercial purposes, or based on surveys presented by the authorities or trade associations. Especially in bilateral and synthetic transactions, the lack of transparency is much more severe since there is no market data available and authorities have to rely on market intelligence. Market data on micro level: due to the fact that securities lending and repo are constructed in various ways, without exact data on transaction level, it might be difficult to seize the real risks that individual market participants pose to the system, especially for the bilateral transactions. Corporate disclosure by market participants: in most authorities, cash-versus-securities transactions are usually reported on-balance sheet. However, according to the accounting standards used in some cases, repos can be reported off-balance sheet, or even disclosure is provided in financial accounts of securiti es-versus-securities transactions, that are typically looked through for the purpose of financial report. The engagement of financial institutions in off-balance sheet transactions without sufficient disclosure may contribute to their risk-taking incentives and eventually increase the fragility of the entire financial system. Risk reporting by intermediaries to their clients: previous to the current crisis, a number of prime brokers had not provide adequate disclosure on re-hypothecation activities to their hedge fund clients. After the collapse of Lehman Brothers International, for instance, many hedge funds turned into unsecured general creditors unexpectedly since they did not realized that the extent to which it had been re-hypothecating client securities. Moreover, some securities lenders, particularly some less sophisticated lenders who have claimed that they were not adequately informed by the agent lenders about the counter-party risk and cash collateral reinvestment risk of their securities lending activities. 4.4 Role of Repo during the Crisis Repo played a crucial role in each stage of the financial crisis, from investor distress in early 2007 to the collapse of major financial institutions at the peak of the crisis in October of 2008. ICMAs Europe European Repo Council (2012) outline and discuss several possible roles that repo played during the current crisis: 4.4.1 Excessive Leverage In theory, repo can allow infinite leverage. For example, a firm finance the purchase of an asset with its own funds initially, then it could repo out the assets to borrow cash and use the cash to buy more assets, and it repos out for more cash and so on. However, the risk of collateralized financing encouraging excessive leverage is somewhat mitigated by the real world constraints on over-borrowing, which apply to both unsecured and secured instruments. This is why Lehman Brothers perpetrated Repo 105 and why MF Global employed repo-to-maturity. And a lthough borrowing levels are only disclosed periodically with a lag and imperfectly, participants in both the unsecured and secured money markets conduct real-time scrutiny of each others borrowing in order to detect patterns of behavior that suggest an unusual hunger for liquidity. It is a gross misunderstanding of the nature of repo that collateral makes lenders indifferent to counter-party credit risk. Some banks have over-leveraged, using both unsecured and secured financing. So, some sort of constraint can be justified. But a mandatory haircut to act as a type of fractional reserve is undesirable, as it would distort the relative pricing of secured versus unsecured instruments. It would also be a very blunt tool, which would reduce liquidity across the entire market, to deal with what should be seen as a problem of risk management specific to individual institutions. General instrument-based approaches are more likely to have unexpected consequences. And, as a matter of prin ciple, concerns about institutions taking excessive leverage should be addressed directly using institution-specific tools such as leverage limits and capital ratios. 4.4.2 Encumber Assets Traditionally, encumbrance is a problem arising from the pledging of collateral, which may be caused when assets are provided as collateral by a borrower. Although those assets still appearing on the borrowers balance sheet, they are no longer available to help meet the claims of unsecured creditors in the event of the insolvency of the borrower. Now repos such as collateral swaps have started to be seen as a source of encumbrance. Encumbrance might arise where repo collateral is subject to an haircut. In this case, it can be argued that the assets represented by the haircut are encumbered, as their sale is not compensated by cash. Hence, it would appear that haircuts structurally subordinate the claims of unsecured creditors over assets given as collateral. However, it should to be remem bered that haircuts are not universally applied nor are they are significant in size. The problem can arise where haircuts are deep, for example, in long-term repo and collateral swaps, over-collateralization could be seen as giving rise to encumbrance. However, the giving of the haircut in such transactions is typically compensated by the buyer pledging the haircut back to the seller, which eliminates any encumbrance. Therefore, the issue of the encumbrance of assets by repos is largely illusory. 4.4.3 Amplify Pro-cyclicality Regulatory concerns that market practices in setting haircuts help to amplify financial market pro-cyclicality envisage a haircut-asset valuation spiral as the amplification mechanism. In an up-cycle, ample liquidity, low volatility, rising asset values, high credit ratings and strong competition for business erode haircuts, contributing to the growth in leverage. When an aggregate shock triggers the start of a down-cycle, haircuts are increased in re sponse to the initial loss of confidence. In the manner of a credit multiplier in reverse, this reduces the liquidity of market users who sell assets in response. Asset sales reduce the value of collateral, causing haircuts to be increased again. And so on. Each market user is behaving rationally from its point of view but, in aggregate, their individual actions create a negative systemic externality. This type of scenario has given rise to the broader claim that the market crisis of 2007-09 was essentially, if not entirely, a run on repo and that repo is an inherent, unstable source of funding. However, the regulatory debate has been taking place largely in the absence of sufficient empirical data on haircuts use or potential impact. Estimates of the likely impact of changes in haircuts on the liquidity of the European repo market between 2007 and 2009, using available data on market size and composition, suggest that their systemic impact may be relatively insignificant in term s of the de-leveraging that took place over this period, which seriously undermines the argument that repo is, by virtue of haircuts, an inherently unstable source of funding. Chapter 5. Regulations in Repo Market 5.1 Current Regulatory Framework of Repo Market FSB (2012) provides a high-level summary of the results of a survey in autumn 2011, conducted by the FSB Workstream on Securities Lending and Repos and the International Organization of Commissions (IOSCO) Standing Committee on Risk and Research, which maps the current regulatory frameworks based on the responses from 12 member authorities (Australia, Brazil, Canada, France, Germany, Japan, Mexico, the Netherlands, Switzerland, Turkey, U.K. and U.S.), the European Commission, and the European Central Bank (ECB). Figure 5.1 outline the main regulatory changes in 12 jurisdictions on different aspects: 5.1.1 Requirements on Financial Intermediations Typically, risk exposures arising from securities lending and rep o transactions are taken into account in the regulatory capital regimes for banks and broker-dealers. Under the Basel capital regime, for instance, banks are requested to hold capital against any counter-party exposures net of the collateral from repo or securities loan associated with an add-on for potential future exposure. Net of the collateral, however, is allowed only when the legal agreement is enforceable under appropriate laws. As well, capital requirements must be held against lent or repoed securities continuously. Furthermore, some other requirements that subject to banks and securities broker dealers are designed in order to improve risk management and strengthen protection on investors. Unlike consistent regulatory capital requirements that has been applied across authorities, there are a variety of tools and details each authority has adopted according to the risks that they need to deal with. 5.1.2 Requirements on Investors Due to the fact that risk exposures arising when investment funds and insurance companies involved in the securities lending and repo markets as investors, it is necessary to design relevant regulatory requirements and activity restrictions to regulate such financial institutions, as well as protect individual investors. Counter-party credit risk, which arising from securities lending and repo transactions, can be alleviated by restrictions on eligible counter-parties and counter-party concentration limits. Concretely, it can be regulated from two aspects: first, restricting eligible counter-parties for securities lending and repo transactions; second, using counter-party concentration limits to alleviate the effect of a large counter-partys default. Liquidity risk, arising from securities lending and repo transactions for insurance companies and MMFs. Some authorities restrict the maturity of securities loans and repos in order to alleviate the liquidity risk. Such maturity limits range from 30 days to around one year. Collateral guidelines, some jurisdictions have introduced collateral guidelines that apply either generally or specifically to securities lending and repos, which include various regulatory tools such as minimum margins and haircuts, eligibility criteria for collateral, restrictions on re-use of collateral and re-hypothecation, and restrictions on cash collateral reinvestment. Transparency, which are similar to the general requirements for public disclosures and regulatory reporting. One exception is that U.S. request insurers who involved in securities lending program to file additional disclosure in reinvested collateral by specific asset categories and stress testing. These disclosures will emphasis the duration mismatch and force the company to explain how they would manage the unexpected liquidity demands. 5.2 Implications for Further Regulation on Repo Market Currently, financial regulation mainly focus on two distinct activities: monitor individual insti tutions impact on system stability, and the protection of investors. For repo markets systemic nature and structural weaknesses, however, regulatory exercise on repo market should focus more on systemic risk of financial institutions, rather than individuals. Acharya and ÃÆ'Æ’-ncà ¼ (2012) mention that unless the systemic liquidity risk of repo market is resolved, the risk of a run on the repo market will still remain. They point out that unlike the unsecured liquidity risk that financing may become unavailable to a firm, the secured liquidity risk that repo financing may become unavailable to a firm is inherently a systemic risk. In other words, markets for the repo securities may be illiquid when most part of financial sector is undergoing undercapitalization or funding stress. In good times, financial firms may not fully internalize the costs imposed on the system by being excessively financed through short-term repo markets, whereas in bad times, they charge excessively high haircuts on repo financing and do not internalize the pecuniary externalities imposed on other firms through the resulting fire sales of assets. In this case, it should be concern that whether to support financial firms facing a repo freeze or to support the assets directly. On one hand, it can subject repo-financed risky securities to a effectively regulatory haircut, which takes into account the securitys systemic risk and maturity mismatch relative to the repo tenor. On the other hand, it can choose a better design of the bankruptcy of a repo-financed debtor than simply granting its repo financier the full right to seize the collateral and liquidate it at will in an illiquid market. Haircuts are widely seen among regulators and academics as contributing to the instability of the repo financing. There is a debate as to whether larger and more stable haircuts should be imposed on the repo market in order to dampen valuation-induced pro-cyclicality in stressed market conditi ons, particularly for collateral assets that are prone to valuation uncertainties. This could be done directly or by the imposition of a countercyclical add-on to capital charges on secured lending to boost haircuts during up-cycles. As the paper of ICMA (2012) mentions, even if haircuts are mandated to remain stable over the business cycle, there are other lending terms that could be used to increase the availability of credit during periods of optimism and constrain credit during periods of de-leveraging, with potentially some of the same pro-cyclical effects on financial markets as that of variable haircuts Moreover, regulators also need to consider that whether mandated minimum haircuts can be sufficiently flexible to efficiently encompass the wide range of combinations of collateral, contract and counter-party that are possible in repo. A policy of one-size-fits-all mandatory haircuts risks distorting the market and creating rigidities that will foster artificial arbitrages. As a matter of principle, concerns about excessive leverage would best be addressed at firm rather than transaction level, by the direct regulation of leverage without concern its source. In addition, the proposal that encourage of more frequent and efficient margin maintenance to smooth out collateral calls seems more helpful than mandated minimum haircuts. Chapter 6. Conclusion This paper mainly focus on two aspects: discuss the role of repo in the current financial crisis, and outline the implications on repo market regulation. As the former comprehensive literature survey on this topic shows that there is no exact answer on what is the main cause for the current crisis and the regulators are still . In this paper, the study just devote to provide a visual understanding on repo market in the 2007-2009 financial crisis. As mentioned above, repo is the crucial part of the shadow banking system, as well played an important role in the current crisis. However, since the lac k of official statistics, there still remains debate on whether run on repo is the main cause of the crisis. Moreover, repo has been viewed as a source of asset encumbrance, has the propensity of collateralized financing to encourage excessive leverage, and the possibility in amplify pro-cyclicality. On the aspect of regulation, after a brief overview of the regulatory framework in repo market, it can be seen that current financial regulation mainly focus on individual, rather than systemic risk. A effectively regulatory haircut, which takes into account the securitys systemic risk and maturity mismatch relative to the repo tenor, might be a good choice to manage the risk in repo-financed securities. However, regulators need to consider that whether mandated minimum haircuts can be sufficiently flexible to efficiently encompass the wide range of combinations of collateral, contract and counter-party that are possible in repo. As a matter of principle, concerns about excessive lev erage would best be addressed at firm rather than transaction level, by the direct regulation of leverage without concern its source.

Bivariate Relationship Between Output and Interest Rates

Question: Discuss about the Bivariate Relationship Between Output and Interest Rates. Answer: Introduction: Correlation coefficient refers to a statistical relationship between two given variables. The variables which may be related may be of two columns of given sets of data which were observed usually defined as a sample. The correlation coefficient is usually applied to statistics to determine how strong two variables are related. There are many types of correlation coefficient which are usually used in linear regression(Babbie, 2012). Scatter plot refers to a graph of plotted points which shows the relationship which exists in a given set of data. Scatter plots are very significant in the field of statistics as they can show the level of correlation between the data of observed phenomena or quantities which are usually referred to as variables. Apart from showing the correlation which exists in a given set of data they also show the sense of correlation(Babbie, 2012). The bivariate relationship is the relationship between two quantitative variables, and it can be done by scattering gram in which one variable's values plotted along the vertical axis and the others along the horizontal axis. The Pearson r is used in the cases when on want to find a linear relationship which exists between two given variable.it can be used either as associative or casual research hypothesis but it cannot be used together with an attributive RH due to its univariate. The Pearson r should be used in the cases where there is a significant effect. (P0.5) In the situations where it is a relationship between two variables. They can be either negative or positive correlation. The Pearson is used where the two quantitative are tested in the RH. This cannot test attributive RH, but can associative and causal(Huh, 2015). The Spearman's rank order correlation is the nonparametric version of the Pearson product moment correlation; Spearman correlation evaluates the monotonic relationship between two continuous or ordinal variables. Spearman correlation is usually applied to the evaluation of relationships involving ordinal variables. Reference Babbie, E. R. (2012). The Basics of Social Research. Texas: Cengage Learning. Huh, C.

Both works of literature were originally written in Chinese and translated later to English. The common feature in these books is that they contain Chinese history and many of the themes are similar. Though depicting different times in the history of China, they both give the reader a glimpse into the daily life of the Chinese in a traditional setting. Although these literary works can be analyzed and interpreted differently, there is one theme, which stands out in both, that is the role of gender in traditional Chinese life. This paper sets out to analyze both books and shed light into how gender was an important aspect of Chinese culture, including the purpose that members of both sets of gender, more so women served in their society. The Story of the Stone: The Golden Days provides an interesting read, especially with its enormous cast of female characters. This book does well to portray the domestic life of the Chinese in the 18th century. It is more of a love story, which delves into the intrigues of wealth and societal status. The author throughout the book portrays women as protagonists, a move contrary to that of previous authors from earlier times. This is not a common feature in Chinese literature given the fact that their society has always been patriarchal. The role of women as embodied in this book brings out the writer as a pro feminist. Women are responsible for most of the happenings in the society at the time, more so in the setting provided. The book can be interpreted simply as a form of literature defining the Chinese societal norms during the time it was set. Other than the outstanding theme of gender, there are others such as education, family and sibling rivalry. Reality and illusion form a central part of the story gi ven that it was initially set in a mythical realm before it was manifested in the actual world. Traditionally, the Chinese people are very religious and mythical, with their culture being an infusion of supernatural beliefs intertwined with real occurrences. For instance, the story begins with a mythical stone, which is a supernatural entity that finds its way into the mortal world. The stone is endowed with consciousness. Its fate is entangled with that of a creature from the Land of Illusion, as it is responsible for its transformation into a fairy girl (Cao 19). This creature vows to repay him with a debt of tears. In the real world, the main male character is born with a jaded spoon in his mouth and growing up is romantically entangled with a sickly girl who is a representation of the creature from the land of illusion. These excerpts are proof of Chinese cultural belief in mythology. From above it is clear how the author intended for the reader to be acquainted with the life of the Chinese people over the centuries. As a reader, I was able to comprehend how this society has undergone transformation over time to what it is today, especially where women are concerned. The love story in the book is the beginning of trouble for the family the author is discussing. In a society where women were betrothed to potential husbands long before they became adults, love between persons other than those intended for them was tragic. This is among the roles women are subjected to in the Chinese culture. There is no room for deciding their course of action as far as marriage is concerned. The main male character who loves a woman, despite him being destined to marry another, suffers this fate. Given an opportunity, they would have been married, despite opposition even from the supernatural realm where the fairy girl swore to avenge the stone through a debt of tears. The author further portrays women as guards of the home. This is evident through his use of various charac ters to depict how they would go to any lengths to protect their families and advance their interests. For instance, the matriarch of the family, the hero’s grandmother, exhibits qualities such as kindness and compassion, which help to keep her family together. She often provides a voice of reason whenever any crisis looms in the household. This is despite the fact that she is in charge of a very large compound of extended family members. One particular aunt fusses over the large family and can be said to be almost perfect in maintaining peace, not to mention how well she gets along with the matriarch. However, one of the more depressing characteristics of women in this book is the subordinate nature. They have been made to resign to less dominant roles, more often defined by their sexuality. Those that are married have to contend with the moral indiscretions of their husbands. The Chinese society has always been patriarchal; therefore, the men could do whatever they pleased even at the detriment of the fairer sex. The sister of the lead male character was groomed to be an official concubine. This is an example of how women at the time were undermined sexually. The entire literary work does little to portray women as being strong and in command of their destiny despite the fact that it still brings out positive aspects of their lives. As aforementioned, China is one of the countries that oppress women greatly, especially at the time when the book was set. Big Breasts and Wide Hips is set in different times in Chinese historical wars and revolutions. The characters in the book take the reader through these periods of change in Chinese society readers are taken through the ordinary life of the Chinese during the war period. Unlike the other book, the background is tumultuous and insecure. In the story of the stone, the story revolved around opulence, what the characters went through to obtain it, their lifestyle and the eventual decline of their dynasties . There was no war; therefore, the tribulations of women were far less concerning than those in this book. However, the domestic setting is still given priority in this work although in a different manner, brought about by the conflicting historical backdrops of the stories at hand. Contrary to the other book, the author of this work brings out women to be strong and in command of their own lives, albeit using unconventional means such as their sexuality. Most chapters of the book are set during wars and revolutions, from the Japanese Invasion to the Mao Communist Era. Before having a male child the matriarch in this story undergoes tremendous abuse from her husband’s family. This is among the ways in which women in this society are oppressed. It was of essence that the patriarchy be extended through generations of male offspring. Failure to do so warrants mistreatment from one’s family. It is of concern that her husband was sterile, a fact which should have been blame d for their misfortunes. Additionally, the wrath unleashed on the matriarch included that of the female members of the household, whom one would expect to come to her defense. These further displays the aspect of submission expected of women in the Chinese society at the time. The sterility of the matriarch’s husband is an obvious hindrance to procreation. Despite this complication, she manages to have nine children with the last being the much desired male heir. This is puzzling except for the fact that readers are taken through her sexual escapades. It therefore goes without question that her children are the result of illicit relationships. Being a war period, these relationships include rape and an incestuous affair with her uncle (Mo 198). None of this matters, for as long as she finally delivers a male heir. All this efforts are in vain because by the time she has a male child all those that persecuted her are dead because of war. It is not of help that she delivers in the middle of a raging battle. One wonders at the sanity of society at the time. The inflictions on womenfolk do not have any justification, especially if the supposed heir fails to live up to societal expectations. In this case, the title of the book attracts the reader to this significant aspect of gender roles. It points at eroticism and some sort of female dominance, at least in the story at hand. The main male character is not befitting of the title. His obsession with female breasts leads him to ultimate ruin. First, he goes on to breastfeed until adulthood and thereafter allows himself to be dominated by his carnal desires. His stint in prison is caused by a foolish sexual act with a dead woman. Women in this book are seen as highly carnal beings that use their feminine attributes to achieve their desires. For instance, all the male protagonist’s sisters climb political and societal ladders, because of illicit affairs. The same women prevent the male heir from ascendin g to his rightful position as he constantly falls into temptation. Conclusively, both books satisfy those that are curious to understand the domestic aspect of the Chinese culture. Based on mythology and traditions passed down through generations, the role of women has been defined in various forms. Though the authors depict different times, their peek at domestic aspects of the Chinese society manages to bring out contrasting yet intriguing roles of women. Sometimes they are strong while other times vulnerable to societal norms and beliefs. However, despite these contrasting portrayals, women have managed to stand out and evolve throughout centuries to what they are today. Much of what they were being subjected to clearly arose from the times they were living in and the occurrences accompanying these periods, such as war. Therefore this paper has served the purpose of effectively analyzing both literary works and discussing the common theme of gender roles with focus on women. Refe rences Cao Xueqin and David Hawkes.

Absolute Error or Absolute Uncertainty Definition

Absolute Error or Absolute Uncertainty Definition Absolute error or absolute uncertainty is the uncertainty in a measurement, which is expressed using the relevant units. Also,  absolute error may be used to express the inaccuracy in a measurement. Absolute error may be called approximation error. Absolute error is the difference between a measurement and a true value: E |x0 - x| Where E is absolute error, x0 is the measured value and x is the true or actual value Why Is There Error? Error is not a mistake. It simply reflects the limitations of measurement instruments. For example, if you use a ruler to measure a length, each tic on the ruler has a width. If a distance falls between marks on the ruler, you need to estimate whether the distance is closer to one mark than the other and by how much. This is error. The same measurement may be taken multiple times to gauge the range of the error. Absolute Error Example If a measurement is recorded to be 1.12 and the true value is known to be 1.00 then the absolute error is 1.12 - 1.00 0.12. If the mass of an object is measured three times with values recorded to be 1.00 g, 0.95 g, and 1.05 g, then the absolute error could be expressed as /- 0.05 g.

Family Law - Essay Example Even though the siblings do not stay in the same house, they must be allowed access to each other and more importantly must be aware of the fact that they have a half sibling. In this case, the boy’s mother does not have any right to keep the fact away from the boy. Also, according to the law half sibling has a right to Visitation and hence the girl has the right to have access to her brother. The boy’s mother cannot ignore the fact that they are half siblings and cannot make the decision for the boy even though he is under her custody. According to law in most jurisdictions, the view of the parent is of not much importance as compared to the interest of both the siblings involved. What is best to the siblings is what matters and hence, the girl in all right must get access to her half brother. As the half siblings will benefit from building a strong relationship by constant visitation, then non-biological parents are required to support and participate in such a visitation. A more serious issue in this case is not the visitation but the boy’s mother’s intention to not tell the boy about his half sister. Such a decision, can turn out be critical in the future for both the half siblings. There are numerous negative effects of half siblings not knowing about each other. Even if they do not have access to each other, they must be aware of the fact that they have a half sibling. There has been a recent incident that shows the negative effect of such secrecy. A couple have discovered that they are half brother and sister after they fell in love and have a child (Hanley, 2011). This is very dangerous and could have been avoided if the couple knew about their relation earlier. Also it is illegal for half siblings to enter the institution of marriage. Hanley, V. (2010). Couple discover they are siblings: Child courts blamed after strangers fall in love, have a son - and then find out they are half-brother and sister.
