金融英语模拟试题及答案Reading Comprehension: (10 points)Joseph Glass, CFA, is a consultant who provides advisory services to large manufacturing companies. Glass has been retained by ABCO, a leading manufacturer of widgets for automobiles in the United States. ABCO has hired Glass to evaluate the possibility of e*panding their current base of operations by building an additional facility in South America. Management of ABCO has identified an increase in demand for widgets in South America over the past decade, and any new manufacturing facility would produce goods to satisfy that void and would be distributed and sold across South America.Glass is not familiar with the current economic climate in South America, but is aware that several governments have attempted to encourage economic development in their countries through the enactment of pro-business legislation. Two of these countries, Venezuela and Peru, both have the reputations of being “friendly” to foreign economic investment withintheir borders. The two countries share some similarities: both, until the past twenty years, were primarily agricultural economies with little industrial development. Also, both countries can offer a relatively low-cost labor force, although their workers in general, are not highly skilled.The government of Peru has declared that protecting the country’s environment is of utmost importance, and has established a regulatory body that oversees any environmental concerns that may arise as the country becomes more industrialized. Fairly stringent regulations have already been put into place in order to ensure that going forward, the operating practices of manufacturers within their country’s borders will be in balance with the government’s concern for their county’s natural resources. Regulations cover areas of concern such as air emissions, water conservation and the use of sustainable resources. Glass advised ABCO that a cost-benefit analysis must be performed to accurately determine both the direct and indirect costs of compliance with the regulations.The Venezuelan government has taken steps to ensurethat it can carefully manage the development of its country’s emerging economy, and to ensure that a competitive market is maintained. A regulatory agency was established five years ago to provide guidance for any new manufacturing concern seeking to operate in Venezuela. The head of the agency is Juan Santos, the former CEO of one of the first modernized manufacturing facilities in the country. During his tenure as head of the agency, he has demonstrated his ability to render decisions that attempt to simultaneously satisfy legislators, industry participants, and consumers. Glass is impressed by Santos’ work so far, but realizes that over the past five years, Venezuela has e*perienced a period of relatively slow economic development. Glass believes that Santos’ skills will truly be put to the test in the upcoming years of the anticipated economic e*pansion.Glass acknowledges the need for governmental regulation of industry, but recognizes that there always are offsetting costs, both short-term and long-term of such controls. Based upon his knowledge of events that have occurred in the United States over thepast thirty years, Glass recommends that ABCO continue to carefully monitor economic developments in both countries even after a site for a new manufacturing facility is selected.Part 1)Should ABCO build a new facility in either of the two countries, it is almost a certainty that they would be the low-cost producer of widgets, with the capacity to satisfy nearly all demand in the region. A natural monopolist operating in an unregulated industry will produce at the point where:A. Marginal costs equal marginal revenue.B. Average costs equal marginal revenue.C. Average costs equal average revenue.D. The marginal cost curve intersects the demand schedule.Part 2)The social regulation policies enacted by the government of Peru would least likely to cause which of the following outcomes? ()A. Higher costs of production.B. A disproportionately higher compliance e*pensefor larger firms rather than smaller firms.C. Higher prices for the end consumer.D. Attempts by industry participants to avoid compliance through creative response.Part 3)If ABCO were to build its new facility in Peru, compliance with the country’s regulatory policies will increase the price of their product by appro*imately ten percent. Some consumers may respond by not replacing the widgets in their automobiles as frequently as before, which will cause decreased fuel efficiency. This unintended effect of regulation is an e*ample of: ()A. The capture hypothesis.B. A creative response.C. A feedback effect.D. The share-the-gains, share-the-pains theory.Part 4)The appointment of Santos, an industry “insider”, to head the regulatory agency in Venezuela has the potential to cause a reaction predicted by which of the following theories of regulatory behavior? ()A. Rate-of-return regulation.B. Share-the-gains, share-the-pains theory.C. The capture hypothesis.D. Cost-of-service regulation.Part 5)Santos, as the head of the main regulatory body in Venezuela, must decide how to manage the effects of an unanticipated sharp increase in the cost of electricity. Santos proposed regulation that will allow manufacturers to pass on the increased costs at scheduled intervals over a five year period. This approach is an e*ample of: ()A. Rate of return regulation.B. Cost-of-service regulation.C. Share-the-gains, share-the-pains theory.D. Social regulation.E*planations of terms：(10 points)1. Liquidity2. Cost-push inflation3.

forecast isσ2100(3)=2+(1.0+0.1×(−2.0)2+0.9×20)=21.4.For model B,the3-step ahead volatility forecast isσ2100(3)=0.1(−2.0)2+0.9×20=18.4.14.Consider the following two models for the log price of an asset:Model A:p t=p t−1+a tModel B:p t=0.00001+p t−1+a twhere the shock a t is normally distributed with mean zero and varianceσ2>0.Suppose further that p100=5.Let p n( )be the -step ahead forecast at the forecast origin n.What are the point forecasts p100( )for both models as →∞?Answer:For model A,p100( )=5for all .For model B,p100( )converges to infinity as →∞.215.Suppose that we have T =1000daily log returns for the Decile 1portfolio.Supposefurther that the sample autocorrelation at lag-12is ˆρ12=0.15.Test the hypothesis H o :ρ12=0against the alternative hypothesis H a :ρ12=pute the test statistic and draw your conclusion.Answer :t =0.151/√1000=√1000×0.15=4.74,which is highly significant.Thus,the lag-12ACF is not zero.Problem B .(20pts)It is well-known in economics that growth rate of the domestic gross product (GDP)is negatively correlated with the change in unemployment rate.Consider the U.S.quarterly real GDP and unemployment rate from the first quarter of 1948to the first quarter of 2008.Let dgdp t be the growth rate of the GDP,i.e.dgdp t =ln(GDP t )−ln(GDP t −1),and dun t be the change in unempolyment rate,i.e.dun t =U t −U t −1with U t being the civilian unemployment rate.The data were seasonally adjusted and obtained from the Federal Reserve Bank at St.Louis.The sample size after the differencing is e the attached R output to answer the following questions.1.(5points)Write down the fitted linear regression model with dgdp t and dun t representing the dependent and independent variable,respectively,including residual standard error.What is the R 2of the linear regression?Is the fitted model adequate?Why?Answer :The fitted linear regression isdgdp t =0.017−0.017dun t +e t ,ˆσe =0.0088.The R 2is 0.37.The model is not adequate because the Q (m )statistics of the residuals show that the residuals have serial correlations,i.e.Q (12)=219.4with p-value close to zero.2.(5points)To take care of the serial correlations in the residuals,a linear regression model with time-series errors is built for the two variables.Write down the fitted model,including the residual variance.Answer :The fitted linear regression model with time-series errors is(1−0.21B −0.12B 2)(1−0.86B 4)(dgdp t −0.017+0.018dun t )=(1−0.72B 4)a t ,ˆσ2a =6.01×10−5.3.(2points)Is the model in Question 2adequate?Why?Answer :Yes,the model is adequate.The Q (m )statistics of the residuals fail to indicate the existence of any serial correlations.We have Q (12)=17.53with p-value 0.13.4.(4points)Based on the fitted model in Question 2,is the growth rate of GDP negatively correlated with the change in unempolyment rate?Why?Answer :Yes,the growth rate of GDP is negatively related to the change in unemploy-ment rate.The estimated coefficient is −0.018which is highly significant,because it standard error 0.0014is small,resulting in a large t -ratio.35.(4points)To check the predictive power of the model,it was re-estimated using thefirst236data points.This re-fitted model is used to produce1-step to4-step ahead forecasts at the forecast origin t=236.The actual value of the GDP growth rates are also given.Construct the1-step ahead95%interval forecast of the model.Is the actual growth rate in the forecasting interval?Answer:The95%interval forecast is0.012±1.96×0.0077,i.e.[−0.0031,0.027].The actual value is0.0159,which is in the interval.Problem C.(16pts)Consider the quarterly earnings per share of the Microsoft stock from thefirst quarter of1992to thefirst quarter of2008.The data were obtained from First Call. To take the log transformation,we add0.5to all data points.The R output is attached. Let x t=ln(y t+0.5)be the transformed earnings,where y t is the actual earnings per share.1.(5points)Write down thefitted model for x t,including the variance of the residuals.Answer:Thefitted model is(1−B)r t=(1−0.70B+0.39B2)(1+0.39B4)a t,ˆσ2a=0.0016, where r t=ln(x t+0.5)with x t being the earnings per share.2.(2points)Is there any significant serial correlation in the residuals of thefitted model?Why?Answer:No,the Q(m)statistics of the residuals give Q(12)=9.65with p-value0.65.3.(4points)Let T=65be the forecast origin,where T is the sample size.Based on thefitted model,and,for simplicity,use the relationship y t=exp(x t)−0.5,what are the 1-step and2-step ahead forecasts of earnings per share for the Microsoft stock?Answer:The1-step and2-step earnings forecasts are0.56and0.54,respectively.4.(2points)Test the null hypothesis H o:θ4=0vs H a:θ4=0.What is the test statistic?Draw your conclusion.Answer:The test statistic is t=0.39120.1442=2.71with two-sided p-value0.0067.Thus,the seasonal MA coefficientθ4is significantly different from zero.5.(3points)Consider the regular(i.e.,non-seasonal)part of the MA model.Is it invertible?Why?Answer:Yes,it is invertible,because the polynomial1−0.6953x+0.3889x2has roots0.89±1.33i so that the absolute value of the roots(Mod in R)is1.6,which is greaterthan1.[If you compute the roots of x2−0.6953x+0.3889,the the absolute value of the roots is less than1.]Problem D.(34pts)Consider the daily log returns of the Starbucks stock,in percentages, from January1993to December2007.The relevant R output is attached.Answer the following questions.41.(2points)Is the mean log return significant different from zero?Why?Answer:No,the basic statistics show the95%confidence interval of the mean is [−0.0103,0.1624],which contains zero.2.(2points)Is there any serial correlation in the log return series?Why?Answer:Yes,the Q(m)statistics show Q(15)=38.39with p-value0.0008.3.(2points)An MA model is used to handle the mean equation,which appears to beadequate.Is there any ARCH effect in the return series?Why?Answer:Yes,because the Q(m)statistics of the squared residuals show Q(15)=112.61 with p-value close to zero.4.(6points)A GARCH(1,1)model with Student-t distribution is used for the volatilityequation.Write down thefitted model,including the degrees of freedom of the Student-t innovations and mean equation.Answer:Thefitted model isr t=0.037+a t−0.043a t−1−0.048a t−2,a t=σt t, ∼t5.27.σ2 t =0.012+0.026a2t−1+0.973σ2t−1.5.(4points)Since the constant term of the GARCH(1,1)model is not significantly differentfrom zero at the1%level,an IGARCH(1,1)model is used.Write down thefitted IGARCH(1,1)model,including the mean equation.Answer:Thefitted IGARCH(1,1)model isr t=0.077+a t−0.029a t−1−0.044a t−2,a t=σt t, t∼N(0,1).σ2 t =0.022a2t−1+0.978σ2t−1.6.(3points)Is the IGARCH(1,1)model adequate?Why?What is the3-step aheadvolatility forecast with the last data point as the forecast origin?Answer:Yes,the Q(m)statistics for the standardized residuals give Q(10)=1.77, Q(15)=10.79,and Q(20)=18.66.The p-values of these statistics are all greater than0.05.In addition,the Q(m)statistics of the squared standardized residuals also havelarge p-values.The3-step ahead volatility forecast is √3.779=1.94.7.(5points)A GJR(or TGARCH)model with Student-t distribution is alsofitted to thelog return series.Write down thefitted model,including the mean equation and all parameters.Answer:Thwfitted GJR model isr t=0.032+a t−0.043a t−1−0.048a t−2,a t=σt t, t∼t5.31.σ2 t =0.015+(0.021+0.017N t−1)a2t−1+0.970σ2t−1,where N t−1=0if a t−1≥0and=1,otherwise.58.(2points)Is the fitted GJR (or TGARCH)model adequate?Why?Answer :Yes,the Q (m )statistics of the standardized residuals and those of the squred standardized residuals all have large p-values.9.(2points)Among the GARCH(1,1),IGARCH(1,1)and GJR(1,1)models,which one is preferred?Why?Answer :The GJR(1,1)model because it has the smallest AIC value.10.(2points)Is the leverage effect of the GJR model significant?Why?Answer :Yes,the t -ratio of the leverage parameter is 2.01,which is significant at the 5%level.11.(4points)To better understand the leverage effect,use the fitted GJR to calculate theratio σ2t (a t −1=−5.10)σ2t(a t −1=5.10),assuming σ2t −1=7.5.Answer :σ2t (a t −1=−5.10)σ2t (a t −1=5.10)=0.0154+0.0379×(−5.10)2+0.97×7.50.0154+0.0208×(5.10)2+0.97×7.5=1.057.6。
