Introduction The sub-prime credit problem that started in the United States during 2007 affected the financial sector in other countries, especially Europe. Deterioration of this sector led to the collapse of national financial systems in different parts of the world, the result being a severe global financial crisis. The magnitude of the recent financial crisis is considered to have no precedent since the Great Depression, the International Monetary Fund (IMF) referring to this global recession as “The Great Recession”.
A study developed by the IMF in 2009 stated that the recent financial crisis has “revealed important flaws in the current global architecture”. The IMF managing Director, Dominique Strauss-Kahn, has underlined, in May 2009, the necessity of a “new global framework” that can ensure a better coordination of national policies (Moshirian, 2010, pp. 5-6). Thus, any national policy must be strongly related with global policies in order to avoid another global financial crisis. However, not few have been those that questioned if a global financial system is desirable.
In order to clarify this debate we must first understand the role of the financial system for the economy. The financial system represents the link between investors and private or public entities. Through this system the economy grows, the consumers also grow their capacity to consume, risks are shared and individuals confront with a smaller volatility on the market. All these correlations extend to the level of the global financial system, a system that works as a powerful and efficient mechanism when the economy is characterized by stability.
Whereas the potential of the financial system certainly exists, words like moral hazard or adverse selection remind us that the economic theory has identified the reasons why financial markets do not always work perfectly, the failure of one or more markets generating losses for the other ones under the conditions of a global financial system. The recent financial crisis, as well as past episodes, teaches us very clearly that the capital flows guided by financial markets can represent something very different from an efficient and optimal allocation of savings towards the right investment projects.
Increasing interconnections of financial institutions and markets lead to highly correlated financial risks, liquidity pressures and depletion of bank capital. Although the recent crisis originated in the United States, due to a highly integrated global economy, the financial markets around the world collapsed and the use of sophisticated financial instruments along with massive international capital flows facilitated its rapid spread across markets and borders (Claessens, Kose, Terrones, 2010). Modern portfolio theory relies on the study developed by Markowitz (1952).
Rubinstein (2002) appreciated that Markowitz’s research represents the first mathematical formalization of the diversification concept of investments, Portfolio Risk Analysis using ARCH and GARCH Models in the Context of the Global Financial Crisis 77 emphasizing the fact that even though diversification reduces risk, it can not eliminate it completely. So, through diversification risk can be reduced without having any effects on the portfolio expected return. Thus, sub-perfectly correlated securities represent the “right candidates” to be included in a portfolio.
Solnik (1974), among others, extended the initial CAPM (Capital Asset Pricing Model) and suggested that international diversification leads to better results than domestic diversification. However, financial integration leads to a significant correlation of security returns, the benefits of international diversification being greatly reduced (Aloui, 2010). Taking all these aspects into consideration, the present paper aims to analyze the evolution of the risk of an internationally diversified portfolio in the context of the current financial crisis.
The remainder of the paper is organized as follows: Section 2 presents theoretical aspects related to the volatility measurement of financial time series using ARCH and GARCH models; in Section 3 we report the empirical results of our study and in Section 4 we provide a summary of our conclusions. 2. Measuring volatility in financial time series: the ARCH and GARCH models Philip Fransens (1988) noted that in the case of financial time series “various sources of news and other exogenous economic events may have an impact on the time series pattern of asset prices.
Given that news can lead to various interpretations, and also given that specific economic events like an oil crisis can last for some time, we often observe that large positive and large negative observations in financial time series tend to appear in clusters” (Gujarati, 2004, p. 856). In practice, linear time series models are incapable to explain a number of important features common to financial data, such as: Leptokurtosis – the tendency for financial asset returns to have distributions that exhibit fat tails; Volatility clustering or volatility pooling – the tendency for volatility to appear in bunches on financial markets.
Thus large returns (of either sign) are expected to follow large returns, and small returns (of either sign) to follow small returns. One of the explanations for this phenomenon, which seems to characterize financial return series, would be the fact that the information arrivals which drive price changes occur in bunches. Leverage effects – the tendency for volatility to rise more following a large price fall, rather than following a price rise of the same magnitude. 78 Oana Madalina Predescu, Stelian Stancu
Campbell, Lo and MacKinlay (1997) defined a non-linear data generating process as one where the current value is related non-linearly to current and previous values of the error term: (1) where et represents an independent and identically distributed (iid) error term, and f is a non-linear function. According to the three researchers, a more specific form of the non-linear model is given by the following equation: (2) where g is a function of past error terms, and ? is the variance term. Campbell, Lo and MacKinlay characterize models with non-linear g as being non-linear in mean and those with non-linear ? as being non-linear in variance. Models can be linear in mean and variance (the classic regression model, ARMA models) or linear in mean, but non-linear in variance (GARCH models) (Brooks, 2010, pp. 380). The most commonly used financial models to measure volatility are the non-linear ARCH and GARCH models. 2 y t = f (e t , et ? 1 , et ? 2 ,… ) y t = g (et ? 1 , et ? 2 ,… ) + et ? 2 (et ? 1 , et ? 2 ,… ) 2. 1. The autoregressive conditional heteroscedasticity model (ARCH) One of the fundamental hypotheses of the classical regression model is the homoscedasticity or the hypothesis of constant error variance: var(et ) = ? (et ) , where et ~ N (0, ? 2 ) . The opposite case is known as heteroscedasticity. In the case of financial time series it is unlikely that the variance of the errors will be constant over time and hence it is preferred to consider a model that does not assume constant variance and which can describe how the variance of the errors evolves. As we mentioned earlier another important feature of financial series is known as volatility clustering or volatility pooling. This characteristic shows that the current level of volatility tends to be positively correlated with its level during the immediately preceding periods.
Using the ARCH model (Engle, 1982) represents one of the modalities through which a phenomenon of this nature can be parameterized. In order to understand how this model works, a definition of the conditional variance of a random variable et is necessary. Thus, the conditional variance of et , denoted ? t2 has the following form: ? t2 = var(et / et ? 1 , et ? 2 ,… ) = E[(et ? E (et )) 2 / et ? 1 , et ? 2 ,… ] (3) Portfolio Risk Analysis using ARCH and GARCH Models in the Context of the Global Financial Crisis 79 Since E (et ) = 0 , equation (3) becomes: t2 = var(et / et ? 1 , et ? 2 ,… ) = E[et2 / et ? 1 , et ? 2 ,… ] (4) Equation (4) states that the conditional variance of a zero mean normally distributed random variable et is equal to the conditional expected value of the square of et . In the case of the ARCH model, the autocorrelation in volatility is modeled by: ? t2 = ? 0 + ? 1 ? et2? 1 (5) The above model is known as ARCH(1) and it shows that the conditional variance of the error term ? t2 , depends on the immediately previous value of the squared error. Equation (5) represents only a part of the model, ince nothing has been specified about the conditional mean. Under the conditions of the ARCH model, the conditional mean equation (which describes how the dependent variable y t varies over time) can take almost any form. One example of a full model would be the following one: y t = ? 1 + ? 2 ? x 2t + ? 3 ? x3t + ? 4 ? x 4t + et ? t2 = ? 0 + ? 1 ? et2? 1 where et ~ N (0, ? 2 ) . (6) (7) So the model given by equations (6)-(7) can be extended to the general case, where the error variance depends on q lags of squared errors, a model known as ARCH( q ): y t = ? 1 + ? 2 ? 2 t + ? 3 ? x 3t + ? 4 ? x 4 t + e t ? = ? 0 + ? 1 ? 2 t et2? 1 + ? 2 ? et2? 2 + … + ? q ? et2? q (8) (9) where et ~ N (0, ? ) . 2 Since ? 2 represents the conditional variance, its value must be strictly t positive (a negative variance at any point in time is meaningless). So all the coefficients in the conditional variance equation must be positive: ? i ? 0, (? )i = 0,1,2,… , q . A natural extension of the ARCH( q ) model is the GARCH model. 80 Oana Madalina Predescu, Stelian Stancu 2. 2. The generalized autoregressive conditional heteroscedastic model (GARCH)
The GARCH model has been developed independently by Bollerslev (1986) and Taylor (1986). This model allows the conditional variance to be dependent upon previous own lags, so that the simplest equation form of the conditional variance is: ? t2 = ? 0 + ? 1 ? et2? 1 + ? ? ? t2? 1 (10) This is a GARCH(1,1) model and the conditional variance can be interpreted as a weighted function of a long term average value (dependent on ? 0 ), of the information related to the volatility during the previous period ( ? 1 ? et2? 1 ) and of the variance during the previous period ( ? ? ? t2? 1 ).
The general form of the GARCH( q , p ) model, where the conditional variance depends on q lags of the squared error and p lags of the conditional variance is: ? t2 = ? 0 + ? 1 ? et2? 1 + ? 2 ? et2? 2 + … + ? q ? et2? q + ? 1 ? ? t2? 1 + + ? 2 ? ? t2? 2 + … + ? p ? ? t2? p (11) or ? t2 = ? 0 + ? ? i ? et2? i + ? ? j ? ? t2? j i =1 j =1 q p (12) In academic literature a GARCH(1,1) model is considered to be sufficient in capturing the evolution of the volatility. A GARCH(1,1) model is equivalent to an ARCH(2) model and a GARCH( q, p ) model is equivalent to an ARCH ( q + p ) model (Gujarati, 2004, p. 62). The unconditional variance of the error term et is constant and given by the following equation: var(et ) = ?0 1 ? (? 1 + ? ) (13) as long as ? 1 + ? < 1 . For ? 1 + ? ? 1 , the unconditional variance of the error et is not defined (non-stationarity in variance), and ? 1 + ? = 1 represents Integrated GARCH or IGARCH (unit root in variance). Portfolio Risk Analysis using ARCH and GARCH Models in the Context of the Global Financial Crisis 81 3. Empirical results 3. 1. Data and descriptive statistics
We selected three benchmark indexes from 3 different countries, namely Romania (BET), UK (FTSE100) and USA (S&P500). We chose these indexes because according to the Pearson correlation coefficient the 3 analyzed markets are not perfectly correlated, representing thus the “right candidates” to be included in the portfolio (Table 1). However, Aloui (2010) underlined in a recent paper that this coefficient is not the best indicator for measuring market interdependence. He stated that this coefficient can not make a clear distinction between large and small returns, or between positive and negative returns.
Moreover, the Pearson correlation estimate is constructed on the basis of the hypothesis of a linear association between the financial return series under consideration, whereas their linkages may well take non-linear causality forms. The solutions that can solve these problems are found in the transformations that can be applied to non-linear models (logarithms) or by using GARCH models. Thus, the study developed in this paper aims to analyze both the benefits of choosing an internationally diversified portfolio and the evolution of the portfolio risk in the context f the current global financial crisis.

We chose a 0. 5 weight for the investment in the BET index, a 0. 5 weight for the investment in the FTSE100 and a 0. 25 weight for the investment in the S&P500, being preferred a passive strategy of portfolio management. 82 Oana Madalina Predescu, Stelian Stancu Table 2 Min Max Mean Standard Deviation Skewness Kurtosis Jarque-Bera Descriptive statistics for the daily index returns BET FTSE100 S&P500 -0. 135461 -0. 092646 -0. 094695 0. 105645 0. 093842 0. 109572 0. 000011 0. 000049 0. 000080 0. 021893 0. 014304 0. 015155 -0. 665793 0. 062484 -0. 029192 8. 364870 11. 03812 12. 24093 1651. 241 3492. 551 4615. 061 Prob. 0. 00000 Prob. 0. 000000 Prob. 0. 000000 Portfolio -0. 088843 0. 087974 -0. 000003 0. 014761 -0. 446707 9. 151124 2087. 874 Prob. 0. 000000 The results show that the riskiest market is the national capital market, the less risky being the UK market. The portfolio risk is moderate in comparison to the risks registered on the markets. The biggest return is obtained in the case of the S&P500 index, the lowest one being obtained by the chosen portfolio. According to the skewness and kurtosis indexes, all data series are asymmetrical and exhibit excess kurtosis.
The Jarque-Bera statistics are highly significant for all return series for a significance level of 1%, being confirmed the assumption that the series are not normally distributed. In Figure 1 is illustrated the variation of the daily returns over the period January 4, 2005 to May 5, 2010. We can observe from the graphics that the returns were fairly stable over the period January 2005 to September 2008. After this date all return series manifested instability especially due to the effects of the global financial crisis.
Moreover, we can observe that the series present two specific features of non-linear models (volatility clustering and leverage). In order to analyze portfolio risk we first estimated a non-linear model with the capacity to capture the evolution of portfolio volatility over the specified time horizon, and the model most commonly used in financial applications of this nature is GARCH(1,1). Before estimating the model we had to detect any ARCH effects in the portfolio return series. Thus we performed the Engle (1982) test.
We chose a number of five lags and using the “least squares method and ARMA” we estimated an ARMA(1,1) model in order to perform afterwards the heteroscedasticity test.

Using the “ARCH method” we estimated the GARCH(1,1) model (the results are shown in Table 4). The coefficients of the squared error and of the conditional variance are highly statistically significant (for a significance level of 1%, 5% and 10%). As expected, in a typical GARCH model for financial data the sum of the coefficients is close to 1. The coefficient of conditional variance is almost 0. 9 and this implies that the shocks to the conditional variance are persistent and that large changes in the conditional variance are followed by other large changes and small changes are followed by other small changes.
The variance intercept coefficient is very small and the coefficient of the squared error is 0. 1.

According to the correlogram there are no additional ARCH terms, a result confirmed also by the ARCH test for the significance levels of 1% and 5% (Tables 5 and 6).

Volatility can be measured through variance or standard deviation. So, the portfolio volatility (measured through standard deviation) is presented in the graphic below:
Figure 2 According to Figure 2 there are more volatile periods than others over the analyzed time period. The most pronounced volatility can be noted between 2008 and 2009 (the highest peak), being observed a slight fall in the next period and then in May 2010 (the end of the chosen time horizon) it can be observed another abrupt increase in the volatility. This evolution of the portfolio 86 Oana Madalina Predescu, Stelian Stancu volatility is attributed to the effects of the current financial crisis that has put a print on the financial markets around the world.
In order to confirm this conclusion we analyzed the daily returns of the indexes over the period 2008-2009 (Figure 3).

Conclusions Studies of the transmission of return and volatility shocks from one market to another as well as studies of cross-market correlations are essential in finance, because they present numerous implications for capital allocation. As it was emphasized in this paper, at first sight some markets may seem slightly correlated, so international portfolio diversification can be in this case an optimal solution.
However, on the background of a highly integrated global financial system, eroded strongly by the effects of the current crisis, international diversification does not reduce portfolio risk. Using in this paper the ARCH and GARCH models we have been able to analyze the evolution of the risk of an internationally diversified portfolio, being chosen three benchmark indexes from three different countries, namely Romania (BET), UK (FTSE100) and USA (S&P500) to be included in the portfolio. We chose a 0. 5 weight for the investment in the BET index, a 0. 25 weight for the investment in the FTSE100 and a 0. 5 weight for the investment in the S&P500. Starting from this portfolio we used the Engle (1982) test in order to track any ARCH effects in the portfolio return series. Taking into consideration that these effects were detected, we were able to estimate a GARCH(1,1) model. The estimation results showed that the volatility is persistent because the coefficient of the conditional variance is 0. 9 and this means that the shocks to the conditional variance are persistent and that large changes in the conditional variance are followed by other large changes and small changes are followed by other small changes.
On the basis of the estimated volatility equation we generated the historical series of the conditional volatility. The graphic of this series shows that there are more volatile periods than others, the most pronounced volatility being observed over the period 2008-2009. This evolution of the portfolio volatility is attributed to the current financial crisis, a fact confirmed by the graphics of the daily index returns over the period 2008-2009. 88 Oana Madalina Predescu, Stelian Stancu References Aloui, R. , „Global financial crisis, extreme interdependences, and contagion effects: The role of economic structure? , Jornal of Banking & Finance, 2010, pp. 1-11 Bollerslev, T. , „Generalized autoregressive conditional heterosceasticity”, Journal of Econometrics, 1986, pp. 307-327 Brooks, C. , (2008).

Also read the additional supplemental material provided below.
Additional supplemental information:
The phrase “driving while black” was coined in 1995 by Henry Louis Gates Jr., a Harvard trained intellectual. The phrase suggests that black individuals are more likely than white individuals to be pulled over by police while driving because of their race. This is only one example of racial profiling within the criminal justice system. Minorities are significantly more likely to be arrested or convicted of a crime than white individuals, whether they are Hispanic, Asian, Middle Eastern, etc. This paper will specifically examine how social and institutionalized racism in the United States causes black individuals to be over-represented within the justice system.
The white population is much larger than the black population in the United States. Considering this, one would expect to see a greater number of white arrests in comparison to black arrests. This is not the case. According to Bureau of Justice statistics, arrest rates for blacks are significantly higher than arrest rates for whites. In 1980 there were approximately 9,447 arrests per 100,000 black individuals, compared to only approximately 3,967 arrests per 100,000 white individuals. This trend has continued since the 1980’s. In 1990 there were approximately 13,128 arrests per 100,000 black individuals, compared to only 4,740 arrests per 100,000 white individuals in the same year. Arrest rates for 2009 show similar disparities. The arrest rate data can be found at:
The difference in arrest rates is not easily explained. Certainly, the difference is tied to a variety of socioeconomic and historical factors. The question of slavery at the founding of our nation and segregation during the last century probably has a lot to do with the differences in socioeconomic conditions seen by whites versus blacks. Police officers, prosecutors and judges are also far more likely to be white than black. The questions at the end of the reading are designed to get you to think about the sources of different arrest rates – and to even question whether the differences are real. Some historically black neighborhoods are patrolled more rigorously by police, making the odds of being caught for crime higher than for some white neighborhoods. Certain crimes such as street gambling, selling narcotics, smoking marijuana, vagrancy, loitering, public intoxication, public urination, open container of alcohol and the like are more easily visible from the streets. It could be that many whites commit crimes behind closed doors and are therefore far less likely to be apprehended in the act of committing a crime. There is also a definite disparage in sentencing when it comes to drugs. Blacks are more likely to be convicted of possession of crack-cocaine, while whites are far more likely to be convicted of possession of the more expensive powdered cocaine. Even though the drugs are essentially the same, the sentence for crack-cocaine possession is many times harsher than for powdered cocaine. There is also the possibility that legislators target vices of blacks specifically. A white business man who commits bank fraud or investor fraud is essentially robbing people of their money. However, the sentences and investigation of white collar money crimes is far less severe than the sentences and investigation of street or store robberies. Once a black is labeled a convicted felon, they can no longer possess a firearm. If they are caught with a gun, they are then charged with another felony, thereby repeating the cycle. It is also harder for them to find a decent job. They are also likely to be on probation or parole after their jail or prison sentence. If they happen to fail a drug test, they are back in jail or prison. It seems in many black neighborhoods that crime is passed down from family to family and from generation to generation; it is really a vicious cycle.

Even Now, There’s Risk in ‘Driving While Black’
By BRENT STAPLES
Published: June 14, 2009
The experience of being mistaken for a criminal is almost a rite of passage for African-American men. Security guards shadow us in stores. Troopers pull us over for the crime of “driving while black.” Nighttime pedestrians cower by us on the streets.
And black men who work as undercover cops are occasionally shot to death by white colleagues, as happened to a young officer named Omar Edwards when he was off duty and in plain clothes last month in New York City.
We have often been seen as paranoid for attributing these things to bias. But the racial stereotypes that link blackness and crime have recently become a hot topic in social science.
These pervasive and often unconscious biases affect social transactions of all kinds. They drive voting behavior. They make it likely that black defendants will receive longer sentences than whites for comparable crimes. They wreak havoc with the job possibilities of young black men. And they give the lie to the idea that the Unites States is becoming a “postracial” country.
The psychologists Gordon Allport and Leo Postman showed more than half a century ago that preconceptions about race distorted human judgment and sometimes caused people to recall things that had never happened. Their best-known study mimicked the parlor game “telephone.”
In this version, subjects who often included students were shown a now-famous slide depicting typical passengers in a New York City subway car. At the center of the image stand two figures: a black man dressed in a natty suit and a white man in shirtsleeves holding a straight razor.
After being shown the slide, subjects were asked to describe it to others who had not seen it. These people then described it to others, who then passed on their descriptions as well. Those who had heard the story secondhand were then asked to recount it. More than half the time, the razor was said to be held not by the white man but by the well-dressed black man, who was sometimes described as brandishing it wildly.
This country has changed considerably in the more than 60 years since these data were published. But the mental calculus that shifted the razor into the black man’s hand is still very much a part of the American scene. It comes into play every day in courtrooms, in city streets and especially in job interviews.
People who believed that racism was on the wane were mightily shocked by the research into the effect of race on hiring policies that appeared in the 2007 book “Marked: Race, Crime and Finding Work in an Era of Mass Incarceration,” by the Princeton sociologist Devah Pager. After sending carefully selected test applicants to apply for low-level jobs with hundreds of employers, Ms. Pager found that criminal convictions for black men seeking employment were, in many contexts, “virtually impossible to overcome,” partly because those convictions reinforced powerful, longstanding stereotypes.
The stigma of conviction turned out to be less damaging for whites. Indeed, white men who claimed to be fresh out of prison were just as likely to be called back for second interviews as black men with no history of criminal involvement. The young black men were best-case applicants — bright, well-spoken college students posing as high school graduates. But racial stereotypes prevented employers from seeing their virtues.
“Being black in America today,” Ms. Pager writes, “is just about the same as having a felony conviction in terms of one’s chances of finding a job.”
People who believe that blunt-force racism is a thing of the past tend to gasp when they see this data. But the findings are consistent with what black job seekers and community organizations have been saying about their experiences for a long time.
All of this should come as sobering news to people who believe that the election of an African-American president moved the country into a new phase beyond racism. We may yet reach that goal. But we won’t do it by pretending that centuries-old biases were magically swept away in a single election. We can do it only by exorcising poisonous preconceptions that go to the very heart of who we are.

Atlanta woman arrested by mistake, jailed 53 days
By DAVID IBATA
Published: October 18, 2011
Atlanta police are launching an internal investigation into the case of a woman who was arrested by mistake and held in jail for nearly two months, Channel 2 Action News reports.
Police are seeking to determine what happened and if any policies or procedures were violated in the arrest of Teresa Culpepper, who spent 53 days wrongfully incarcerated in Fulton County Jail because she had the same name, Teresa, as a woman wanted by authorities.
“I didn’t know what to do. I didn’t know how to get out this situation,” Culpepper told Channel 2.
The woman’s nightmare began Aug. 21, when she called police to report her truck had been taken from in front of her Hawkins Street home. She ended up being arrested for an aggravated assault allegedly committed by another woman named Teresa.
“Her birth date didn’t match. Her address didn’t match. Her description didn’t match. Other than the name Teresa, nothing matched,” said Culpepper’s attorney, Ashleigh Merchant.
Channel 2 tracked down the Teresa actually wanted by police, and the woman told the TV station she had never been arrested for the alleged offense.
Culpepper finally was released Oct. 12 after her public defender got the crime victim to come to court and say the woman in custody was not the attacker.
“I was like real rejoiceful, glad and happy that it came to an end and that somebody was out there, out there trying to help me,” Culpepper said.
Ashleigh said the city now must either settle with her client or face legal action.
This assignment is designed to test your understanding of the various theories used to explain criminal behavior as presented in your textbook and in journals or libraries or anywhere online that is of scholarly caliber. Remember; please answer each question in 1.5-2, preferably single-spaced, pages. Your answers should indicate that you have researched the topic independently using your textbook, library, government and internet sources. Your textbook is also a good source – but please include information not provided in the required text as well.
1. Use social structural theories to explain how the structure of U.S society may cause minorities to be over-represented within the criminal justice system. You should pay specific attention to social disorganization theory, strain theory, and culture conflict theory. (do your own external research)
2. Use social process theories to critique social structural theories. Pay specific attention to differential association theory and labeling theory. Explain why these theories may better explain the over-representation of minorities in the criminal justice system. (do your own external research)
3. Survey the various radical theories of crime as presented in chapter 7 of your textbook. Briefly use the conflict and radical criminology theories to critique labeling theory, conflict theory, and “Marxist” theory. Explain how radical theories of deviance can provide an alternative explanation of why minorities are over-represented in the U.S criminal justice system. (do your own external research)
4. Finally, apply one of these theories to the first op-ed included with this assignment. The author in the first op-ed is suggesting that the United States is not a color blind society – do you believe that this is true? Use theory and evidence to support your argument. Feel free to either agree with or critique the author’s opinion. (do your own external research)
