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.

时间序列期末考试英文Title: Characterizing Long-Term Temporal Patterns in Stock Market DataAbstract:This study presents an analysis of long-term temporal patterns in stock market data, aiming to identify trends, cycles, and potential predictability. We employed advanced time series techniques to extract meaningful patterns from historical stock price data. Our findings suggest the presence of distinct long-term cycles, which may offer valuable insights for investors and traders.Keywords: Stock Market, Time Series Analysis, Long-Term Trends, CyclesIntroduction:The stock market is a complex system, characterized by high volatility and unpredictability. However, understanding its long-term temporal patterns can provide valuable insights for investors. In this study, we aim to identify long-term trends and cycles in stock market data, utilizing advanced time series analysis techniques.Methodology:We collected historical daily closing prices for a broad market index (e.g., S&P 500) spanning over a period of 20 years. We employed various time series analysis techniques, including autocorrelation, cross-correlation, Fourier analysis, and wavelet transforms, to extract meaningful patterns from the data.Results:Our analysis revealed several long-term temporal patterns in the stock market data. We identified significant autocorrelation in the data, suggesting the presence of persistent trends. Fourier analysis revealed distinct long-term cycles with periods ranging from 5 to 10 years. Wavelet transforms further confirmed these cycles and provided insights into their evolution over time.Conclusion:Our findings suggest that the stock market exhibits distinct long-term temporal patterns characterized by persistent trends and cycles. These patterns may offer valuable insights for investors and traders, enabling them to make more informed decisions.

exam12s经典教材《金融时间序列分析》Ruey S. Tsay 英文第三版2012年试题及答案高清版

Booth School of Business,University of ChicagoBusiness41202,Spring Quarter2012,Mr.Ruey S.TsaySolutions to MidtermProblem A:(34pts)Answer brieﬂy the following questions.Each question has two points.1.Describe two improvements of the EGARCH model over the GARCHvolatility model.Answer:(1)allows for asymmetric response to past positive or negative returns,i.e.leverage eﬀect,(2)uses log volatility to relax parameter constraint.2.Describe two methods that can be used to infer the existence of ARCHeﬀects in a return series,i.e.,volatility is not constant over time.Answer:(1)The sample ACF(or PACF)of the squared residuals of the mean equation,(2)use the Ljung-Box statistics on the squared residuals.3.Consider the IGARCH(1,1)volatility model:a t=σt t withσ2t =α0+β1σ2t−1+(1−β1)a2t−1.Often one pre-ﬁxesα0=0.Why?Also,suppose thatα0=0and the1-step ahead volatility prediction at the forecast origin h is16.2%(annualized),i.e.,σh(1)=σh+1=16.2for the percentage log return.What is the10-step ahead volatility prediction?That is,what isσh(10)?Answer:(1)Fixingα0=0based on the prior knowledge that volatility is mean reverting.(2)σh(10)=16.2.4.(Questions4to8)Consider the daily log returns of Amazon stockfrom January3,2007to April27,2012.Some summary statistics of the returns are given in the attached R output.Is the expected(mean) return of the stock zero?Why?Answer:The data does not provide suﬃcient evidence to suggest that the mean return is not zero,because the95%conﬁdence interval con-tains zero.5.Let k be the excess kurtosis.Test H0:k=0versus H a:k=0.Writedown the test statistic and draw the conclusion.1Answer:t-ratio =9.875√24/1340=73.79,which is highly signiﬁcant com-pared with χ21distribution.6.Are there serial correlations in the log returns?Why?Answer:No,the Ljung-Box statistic Q (10)=10.69with p-value 0.38.7.Are there ARCH eﬀects in the log return series?Why?Answer:Yes,the Ljung-Box statist of squared residuals gives Q (10)=39.24with p-value less than 0.05.8.Based on the summary statistics provided,what is the 22-step ahead point forecast of the log return at the forecast origin April 27,2012?Why?Answer:The point forecast r T (22)=0because the mean is not signif-icantly diﬀerent from zero.[Give students 1point if they use sample mean.]9.Give two reasons that explain the existence of serial correlations in ob-served asset returns even if the true returns are not serially correlated.Answer:Any two of (1)bid-ask bounce,(2)nonsynchronous trading,(3)dynamic dependence of volaitlity via risk premuim.10.Give two reasons that may lead to using moving-average models inanalyzing asset returns.Answer:(1)Smoothing (or manipulation),(2)bid-ask bounce in high frequency returns.11.Describe two methods that can be used to compare diﬀerent modelsfor a given time series.Answer:(1)Information criteria such as AIC or BIC,(2)backtesting or out-of-sample forecasting.12.(Questions 12to 14)Let r t be the daily log returns of Stock A.Assume that r t =0.004+a t ,where a t =σt t with t being iid N(0,1)random variates and σ2t =0.017+0.15a 2t −1.What is the unconditionalvariance of a t ?Answer:Var(a t )=0.0171−0.15=0.02.13.Suppose that the log price at t =100is 3.912.Also,at the forecastorigin t =100,we have a 100=−0.03and σ100=pute the21-step ahead forecast of the log price (not log return)and its volatility for Stock A at the forecast origin t =100.Answer:r 100(1)=0.004so that p 100(1)=3.912+0.004=3.916.Thevolatility forecast is σ2100(1)= 0.017+0.15(−0.03)2=pute the 30-step ahead forecast of the log price and its volatilityof Stock A at the forecast origin t =100.Answer:p 100(30)=3.912+0.004×30=4.032and the voaltility is the unconditional stantard error √0.02=0.141.15.Asset volatility has many applications in ﬁnance.Describe two suchapplications.Answer:Any two of (1)pricing derivative,(2)risk management,(3)asset allocation.16.Suppose the log return r t of Stock A follows the model r t =a t ,a t =σt t ,and σ2t =α0+α1a 2t −1+β1σ2t −1,where t are iid N(0,1).Under whatcondition that the kurtosis of r t is 3?That is,state the condition under which the GARCH dynamics fail to generate any additional kurtosis over that of t .Answer:α1=0.17.What is the main consequence in using a linear regression analysis whenthe serial correlations of the residuals are overlooked?Answer:The t -ratios of coeﬃcient estimates are not reliable.Problem B .(30pts)Consider the daily log returns of Amazon stock from January 3,2007to April 27,2012.Several volatility models are ﬁtted to the data and the relevant R output is attached.Answer the following questions.1.(2points)A volatility model,called m1in R,is entertained.Write down the ﬁtted model,including the mean equation.Is the model adequate?Why?Answer:ARCH(1)model.r t =0.0018+a t ,a t =σt t with t being iidN(0,1)and σ2t =7.577×10−4+0.188a 2t −1.The model is inadequatebecause the normality assumption is clearly rejected.2.(3points)Another volatility model,called m2in R,is ﬁtted to the returns.Write down the model,including all estimated parameters.3Answer:ARCH(1)model.r t=4.907×10−4+a t,a t=σt t,where t∼t∗3.56with t∗vdenoting standardized Student-t distribution with v degreesof freedom.The volatility equation isσ2t =7.463×10−4+0.203a2t−1.3.(2points)Based on theﬁtted model m2,test H0:ν=5versus H a:ν=5,whereνdenotes the degrees of freedom of Student-t distribution.Perform the test and draw a conclusion.Answer:t-ratio=3.562−50.366=−3.93,which compared with1.96is highlysigniﬁcant.If you compute the p-value,it is8.53×10−5.Therefore, v=5is rejected.4.(3points)A third model,called m3in R,is also entertained.Writedown the model,including the distributional parameters.Is the model adequate?Why?Answer:Another ARCH(1)model.r t=0.0012+a t,a t=σt t,where t are iid and follow a skew standardized Student-t distribution with skew parameter1.065and degrees of freedom3.591.The volatility equationisσ2t =7.418×10−4+0.208a2t−1.Ecept for the insigicant mean value,theﬁtted ARCH(1)model appears to be adequate based on the model checking statistics shown.5.(2points)Letξbe the skew parameter in model m3.Does the estimateofξconﬁrm that the distribution of the log returns is skewed?Why?Perform the test to support your answer.Answer:The t-ratio is1.065−10.039=1.67,which is smaller than1.96.Thus,the null hypothesis of symmetric innovations cannot be rejected at the 5%level.6.(3points)A fourth model,called m4in R,is alsoﬁtted.Write downtheﬁtted model,including the distribution of the innovations.Answer:a GARCH(1,1)model.r t=0.0017+a t,a t=σt t,where t are iid and follow a skew standardized Student-t distribution with skew parameter1.101and degrees of freedom3.71.The volatility equationisσ2t =1.066×10−5+0.0414a2t−1+0.950σ2t−1.7.(2points)Based on model m4,is the distribution of the log returnsskewed?Why?Perform a test to support your answer.Answer:The t-ratio is1.101−10.043=2.349,which is greater than1.96.Thus,the distribution is skew at the5%level.48.(2points)Among models m1,m2,m3,m4,which model is preferred?State the criterion used in your choice.Answer:Model4is preferred as it has a smaller AIC value.9.(2points)Since the estimatesˆα1+ˆβ1is very close to1,we consideran IGARCH(1,1)model.Write down theﬁtted IGARCH(1,1)model, called m5.Answer:r t=a t,a t=σt t,whereσ2t =3.859×10−5+0.85σ2t−1+0.15a2t−1.10.(2points)Use the IGARCH(1,1)model and the information providedto obtain1-step and2-step ahead predictions for the volatility of the log returns at the forecast origin t=1340.Answer:From the outputσ21340(1)=σ21341=3.859×10−5+0.85×(0.02108)2+0.15(.146)2=0.00361.Therefore,σ21340(2)=3.859×10−5+σ2 1340(1)=0.00365.The volatility forecasts are then0.0601and0.0604,respectively.11.(2points)A GARCH-M model is entertained for the percentage logreturns,called m6in the R output.Based on theﬁtted model,is the risk premium statistical signiﬁcant?Why?Answer:The risk premium parameter is−0.112with t-ratio−0.560, which is less than1.96in modulus.Thus,the risk premium is not statistical signiﬁcant at the5%level.12.(3points)Finally,a GJR-type model is entertained,called m7.Writedown theﬁtted model,including all parameters.Answer:This is an APARCH model.The model is r t=0.0014+a t,a t=σt t,where t are iid and follow a skew standardized Student-tdistribution with skew parameter1.098and degrees of freedom3.846.The volatility equation isσ2 t =7.583×10−6+0.0362(|a t−1|−0.478a t−1)2+0.953σ2t−1.13.(2points)Based on theﬁtted GJR-type of model,is the leverage eﬀectsigniﬁcant?Why?Answer:Yes,the leverage parameterγ1is signﬁicantly diﬀerent from zero so that there is leverage eﬀect in the log returns.5Problem C.(14pts)Consider the quarterly earnings per share of Abbott Laboratories(ABT)stock from1984.III to2011.III for110observations.We analyzed the logarithms of the earnings.That is,x t=ln(y t),where y t is the quarterly earnings per share.Two models are entertained.1.(3points)Write down the model m1in R,including residual variance.Answer:Let r t be the log earnings per share.Theﬁtted model is=0.00161.(1−B)(1−B4)r t=(1−0.565B)(1−0.183B4)a t,σ2a2.(2points)Is the model adequate?Why?Answer:No,the Ljung-Box statistics of the residuals give Q(12)=25.76with p-value0.012.3.(3points)Write down theﬁtted model m2in R,including residualvariance.Answer:Theﬁtted model is=0.00144.(1−B)(1−B4)r t=(1−0.470B−0.312B3)a t,σ2a4.(2points)Model checking of theﬁtted model m2is given in Figure1.Is the model adequate?Why?Answer:Yes,the model checking statistics look reasonable.5.(2points)Compare the twoﬁtted model models.Which model ispreferred?Why?Answer:Model2is preferred.It passes model checking and has a smaller AIC value.6.(2points)Compute95%interval forecasts of1-step and2-step aheadlog-earnings at the forecast origin t=110.Answer:1-step ahead prediction:0.375±1.96×0.038,and2-step ahead prediction:0.0188±1.96×0.043.(Some students may use2-step ahead prediction due to the forecast origin confusion.)Problem D.(22pts)Consider the growth rate of the U.S.weekly regular gasoline price from January06,1997to September27,2010.Here growth rate is obtained by diﬀerencing the log gasoline price and denoted by gt in R output.The growth rate of weekly crude oil from January03,1997to September24,2010is also obtained and is denoted by pt in R output.Note that the crude oil price was known3days prior to the gasoline price.61.(2points)First,a pure time series model is entertained for the gasolineseries.An AR(5)model is selected.Why?Also,is the mean of the gtseries signiﬁcantly diﬀerent from zero?Why?Answer:An AR(5)is selected via the AIC criterion.The mean of g tis not signiﬁcantly diﬀerent from zero based on the one-sample t-test.The p-value is0.19.2.(2points)Write down theﬁtted AR(5)model,called m2,includingresidual variance.Answer:Theﬁtted model is=0.000326.(1−0.507B−0.079B2−0.136B3+0.036B4+0.086B5)g t=a t,σ2a3.(2points)Since not all estimates of model m2are statistically signiﬁ-cant,we reﬁne the model.Write down the reﬁned model,called m3.Answer:Theﬁtted model is=0.000327.(1−0.504B−0.074B2−0.122B3+0.101B5)g t=a t,σ2a4.(2points)Is the reﬁned AR(5)model adequate?Why?Answer:Yes,the Ljung-Box statistics of the residuals give Q(14)=10.27with p-value0.74,indicating that there are no serial correlationsin the residuals.5.(2points)Does the gasoline price show certain business-cycle behavior?Why?Answer:Yes,theﬁtted AR(5)polynomial contains compplex solutions.6.(3points)Next,consider using the information of crude oil price.Writedown the linear regression model,called m4,including R2and residualstandard error.Answer:Theﬁtted linear regression model isg t=0.287p t+ t,σ =0.0184,and the R2of the regression is33.66%.7.(2points)Is theﬁtted linear regression model adequate?Why?Answer:No,because the residuals t are serially correlated based onthe Ljung-Box test.78.(3points)A linear regression model with time series errors is enter-tained and insigniﬁcant parameters removed.Write down theﬁnalmodel,including allﬁtted parameters.Answer:The model is(1−0.404B−0.164B2−0.096B3+0.101B5)(g t−0.191p t)=a t,σ2=0.000253.a9.(2points)Model checking shows that theﬁttedﬁnal model has noresidual serial correlations.Based on the model,is crude oil pricehelpful in predicting the gasoline price?Why?Answer:Yes,because theﬁtted coeﬃcient of p t is signﬁcantly diﬀerentfrom zero.10.(2points)Compare the pure time series model and the regression modelwith time-series errors.Which model is preferred?Why?Answer:The regression model with time series error is preferred as ithas a smaller AIC

A:No,because the two roots are real.From1?0.371x2,we have x=±1/ (0.371).15.Give two weaknesses of the GARCH-type of models for modeling asset volatility.A:Any two of(a)symmetric response to past positive and negative returns,(b)restric-tive,(c)providing no explanation of volatility clustering,(d)no adaptive in forecasting.2Problem B.(20pts)This problem is concerned with theanalysis of quarterly earnings per share of the Procter&Gamble(PG)Company from1992to the?rst quarter of2003 for45data points.The data were obtained from First Call.Log transformation was taken to stabilize the variability of the /doc/889308787.html,puter output is attached;p.2-6of output. Due to strong seasonal pattern,which results in models that are close to being non-invertible, we analyze the seasonally di?erenced series in Splus.Let x t be the logarithm of quarterly earnings per share and w t=(1?B4)x t.Thus,SCA uses x t and Splus uses w t.1.(5points)Because ACF of the log earnings shows strong seasonal pattern,the seasonaldi?erence(1?B4)is taken.The ACF of the seasonally di?erenced data indicates no further di?erencing is necessary.Write down the?tted model for the x t series(not the di?erenced w t).A:(1?0.47B)(1?B4)x t=0.0508+(1?0.307B4)a t,σa=0.0502.2.(4points)Is the AR coe?cient of the?tted model statistically signi?cant?Why?A:Yes,the t-ratio is3.26,which is greater than the critical value1.96.3.(4points)Is there any serial correlation in the residuals of the?tted model?Use Q(12)of the ACF of residuals to answer the question.[Hint:for a chi-square distribution with m degrees of freedom,the expected value is m.]A:Q(12)=8.8which is less than E(χ210)=10so that p-value>0.05.4.(4points)Let T=45be the forecast origin.What are the1-step and2-step aheadforecasts of the?tted model(after taking anti-logtransformation)?A:x45(1)=0.912and x45(2)=3.95(from SCA).For Splus,x45(1)=exp(0.0087?.1743)=0.847,x45(2)=exp(?.012479+1. 278152)=3.55.5.(3points)Give an interpretation of the estimated constant0.0508of the?tted modelfor x t.A;Slope of time trend.3and the S&P500index from January1999to December2004with sample size T=1508.We employ the market model:r t=α+βr m,t+e t,where r t and r m,t are Wal-Mart stock return and S&P500index return,respectively.Splus output is attached;page6of output.Answer the following questions.1.(4points)Write down the?tted market model.A:r t=0.0205+0.9606r m,t+e t.2.(4points)The Ljung-Box statistics of the ACF of residuals show some minor serialcorrelations,but the ACFs are relatively small so we ignore the serial correlations and perform the ARCH e?ect test.Is there an ARCH e?ect in the residuals of the?tted market model?A:Yes,archTest gives a p-value about0.0.3.(4points)We employ a GARCH(1,1)model(called“m2”in the output).Write downthe?tted /doc/889308787.html,ment on the?tted model.A:Let r t and r m,t be the Wal-Mart stock return and S&P500index return,respectively.The model isr t=0.9386r m,t+a t=0.9386+σt t, t～t6.41σ2t=?4.29×10?5+0.0377a2t?1+0.963σ2t?1.The negative estimate ofα0does not make sense,but it is statistically not di?erent from0.Also,the?α1+?β1≈1so that the?tted model indicates an IGARCH(1,1)model without the constant.4.(6points)Further analysis indicates that an EGARCH(2,1)model?ts the data better.There are two leverage e?ect parameters.Are these two e?ects statistically signi?cant?Why?You may test the e?ect individually.A:Examine the t-ratio of the two leverage parameter estimates.For Lev(1),the t-atio is?2.129.For Lev(2),the t-ratio is?1.847.In both cases,the p-values are less tha0.05so that they are both signi?cant.[It you use two-sided tests,then Lev(2)is notsigni?cant.]5.(2points)What are the1-step ahead forecasts for the return and its volatility of Wal-Mart stock at the forecast origin T=1508using the EGARCH model.A:zero for return and0.7082for volatility.4from January1995to December2004with2519observations.Splus output is attached;page 8of output.Answer the following questions.The ACFs of the returns are small so that the mean equation consists of a constant term only.1.(5points)Consider the?tted GARCH(1,1)model.The volatilityequation isσ2t=0.042+0.049a2t?1+0.944σ2t?1.Letηt=a2t?σ2t.Rewrite the prior vo latility equation in an ARMA form for the{a2t} series.A:a2t=0.042+0.993a2t?1+ηt?0.944ηt?1.2.(5points)Write down the?tted EGARCH(1,1)model with leverage e?ect(both meanand volatility equations and the parameter of the conditional distribution used).A:The model isr t=0.04918+a t=0.04918+σt t, t～t6.68ln(σ2t)=?0.06316+0.1033(|a t?1|?0.5464a t?1σt?1)+0.989ln(σ2t?1).3.(4points)Test the hypotheses H o:v=5vs H a:v=5,where v is the degrees offreedom of the conditional Student t distribution.Draw your conclusion.[Hint:you may use the usual t-ratio test.]A;t-ratio=6.684?5=2.62>1.96.Thus,reject H o:v=5.4.(5points)To better understand the leverage e?ect,use the?tted EGARCH(1,1)modelto calculate the ratioσ2t( =?3)2t ,where t denotes the iid sequence of the innovationsde?ned in class.A:From the?tetd volatility equation,we haveσ2t=exp(?0.06316)(σ2t?1).989exp(0.1033| t?1|?0.0564 t?1). Therefore,σ2t( =?3)σ2t( =3)=exp(?0.0564(?3))exp(?0.0564(3))=exp(0.0564×6)=1.403.5.(4points)Used the?tted EGARCH model and T=2519as the forecast origin.Whatare the1-step ahead forecasts of log return and volatility?A:Forecast of log return is0.0492and forecast of volatility is1.184.6.(4points)Write down the mean equation of the?tted GARCH-M model for the data.A:r t=0.058+0.00629σ2t+a t.7.(3points)Based on the GARCH-M model,is the risk premium statistically signi?cant?Why?A:No,the t-ratio is0.453with p-value=0.65(two-sided).5。

一、单项选择题（每题2分，共20分） P61关于严平稳与（宽）平稳的关系；弱平稳的定义：对于随机时间序列y t ，如果其期望值、方差以及自协方差均不随时间t 的变化而变化，则称y t 为弱平稳随机变量，即y t 必须满足以下条件：对于所有时间t ，有（i ）E （yt ）=μ为不变的常数；（ii ） Var （yt ）=σ²为不变的常数；（iii ） γj =E[y t -μ][y t-j -μ]，j=0，±1，,2，… （j 为相隔的阶数）（μ=0，cov （y t ，y t-j ）=0，Var （yt ）=σ²时为白噪音过程，常用的平稳过程。

）从以上定义可以看到，凡是弱平稳变量，都会有一个恒定不变的均值和方差，并且自协方差只与y t 和y t-j 之间的之后期数j 有关，而与时间t 没有任何关系。

严平稳过程的定义：如果对于任何j 1,，j 2，...,j k ,随机变量的集合（y t ，y t+j1,，y t+j2，…，y t+jk ）只依赖于不同期之间的间隔距离（j 1，j 2，…，j k ），而不依赖于时间t ，那么这样的集合称为严格平稳过程或简称为严平稳过程，对应的随机变量称为严平稳随机变量。

P46 t X 的k 阶差分是；△ｋX t =△ｋ-1X t -△ ｋ-1X t-1，△ 表示差分符号。

滞后算子；P54对于AR ： L p y t =y t-p ，对于MA ：L ｐεt =εt-ｐAR （p ）模型即自回归部分的特征根—平稳性；确定好差分方程的阶数，则其特征方程为：λp-α1λp-1-α2λp-2-…-αp =0，若所有的特征根的│λ│<1则平稳补充：逆特征方程为：1-α1ｚ1-α2ｚ²-…-αp ｚp=0，若所有的逆特征根│ｚ│>1，则平稳。

注意：特征根和逆特征方程的根互为倒数。

金融时间序列试卷

内蒙古财经学院2011——2012学年第1学期《金融时间序列分析》试卷答案一、填空题（1分*15空二15分）1.Xt =0心_1+0X^2 ---------- 0pXt・p+$t 一厲斫-1 ------ %、朝、…帖厲、…、%。

2.描述性：3.兀=斗』+耳，0,1,0；4平稳性检验，纯随机性检验；5. VPx t = （1 - B）Pxt, V k x t = （1 - B k）x t；6 宽平稳，严平稳，宽平稳：7.自回归二、不定项选择题（2分*5题=10分）1、AC2、ABD3、AB4、ABCD5、ABD三、判断并说明理由（2题*5分=10分）1、如果一个时间序列宽平稳，则它肓定不是严平稳；如果一个时间序列严平稳，则它一定是宽平稳。

答：说法是错误的。

（1分）严平稳是一种条件比较苛刻的平稳性定义，该定义表明，一个序列的所有统计均平稳时，该序列才是平稳的。

而宽平稳则是条件宽松的平稳性定义，即只要求序列的二阶矩平稳，则序列就是平稳的。

由定义町知，在一般情况下，如果一个时间序列是宽平稳的，则它肯定不是严平稳的；如果一个时间序列是严平稳的，则它一定是宽平稳的。

（2分）但两种情况各有例外，如多元正态分布，二阶矩包插所有•统计性质，所以对于服从多元正态分布的序列，宽平稳也是严平稳：再比如柯酋分布不存在二阶矩，因此如果一个序列服从柯西分布，且为严平稳, 但却推不出其为宽平稳。

确切的说应该是对于存在二阶矩的序列，严平稳才能推出宽平稳。

（2分）2、差分运算的实质是使用自回归的方式提取确定性信息答：说法是正确的。

（5分〉四、简答题：（25分）1、简述平稳序列的建模步骤（7分）答：（1）时间序列分析的第-步是获得观察值序列，然后对这个序列进行平稳性检验，对平稳的序列进行纯随机性检验，如果是纯随机序列，分析结束：如果不是纯随机序列，选择模型拟合该序列：（2）求出该观察值序列的样本自相关系数（ACF）和样本偏自相关系数（PACF）的值。

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。
