This assignment is worth 30% of the total mark and should be submitted
by Sunday, 11:55 PM Sunday 3 October, using the electronic submission
facility available at the LMS. This is an individual assignment.
Plagiarism will be dealt with according to the University policy.
Members of the teaching staff are not allowed to help on any aspect of
the assignment, and will not answer the questions directly related to
the assignment unless they are for clarification of the assignment
questions. Late submission will be penalised with 2% (two percent) per
any extra day delay up to the maximum of five (5) working days after the
submission date. Submission of special consideration applications
should be made online accordingly to the new policy. For more
information, refer to
https://policies.latrobe.edu.au/document/view.php?id=205. The report
should provide concise and relevant answers to all questions below and
the corresponding computer outputs. It does not need to follow a formal
report format. In conducting statistical tests throughout, clearly state
all relevant information, such as the null and alternative hypotheses,
the distribution that has been used the level of significance and the
decision rule (critical value or p-value). The report should be typed on
A4 pages; the text should be double-spaced and in ‘Times New Roman’
font. The following two separate files should be submitted with clear
identification of name, surname and student ID: (Hint: Save all files
with the filename: “Assignment_FirstName_ID.***”) 1) An Eviews file
containing all estimated descriptive statistics and models. 2) A written
report not exceeding 1,000 words of the results of the required
analysis. 2 Data Details and Background (No Questions) The file
assignment.wf1 contains the US stock price (S&P 500, RP) and
dividend (S&P 500, RD), all adjusted for inflation, monthly from Jan
1871 to Mar 2018. The data are obtained from Robert Shiller’s website
(http://www.econ.yale.edu/~shiller/). Finance literature has documented
relationship between stock price, earning, and dividend in the short-run
and long run. The question whether the dividend, or earning has
explanatory or predictive power for future stock returns is a
contentious issue in finance. In this assignment, you will analyze the
relationhip between stock price, earning and dividend in the short and
long-run using the data mentioned above above set from the U.S. stock
market. A section of Fabozzi et al. (2014, pp 199-205) is useful as a
background and as an example of statistical analysis on this topic.
Since the nature of the relationship can change over time (due to
structural change; institutional changes; policy changes, etc.), it is
recommended to break the data set into different windows. This will also
demonstrate how the short-run and long-run relationship (if it exists)
has changed over time. The data set is subdivided into different
windows; each covering a period of 40 years (480 monthly observations)
as below: Data Set Number Period 0 1888:04 – 1928:03 1 1898:04 – 1938:03
2 1908:04 – 1948:03 3 1918:04 – 1958:03 4 1928:04 – 1968:03 5 1938:04 –
1978:03 6 1948:04 – 1988:03 7 1958:04 – 1998:03 8 1968:04 – 2008:03 9
1978:04 – 2018:03 You are assigned with the window which matches the
last digit of your student ID. For example, if the last digit of your ID
is 5, you should use the data set 5 which covers the period from 1938 –
1978. If you use the wrong data set, your mark for this assignment will
be 0. 3 In Eviews, you can set the data range by clicking on the Sample
Button and writing the required sample range (1938m04 1978m03 is used
as an example; you will need the range relevant to your sample range).
Click OK; then the sample range is reset with the corresponding 480
observations. It is usual to transform the data into a natural log. This
procedure is necessary to estimate the elasticity and to stabilize the
variance of the data by transforming them into a smaller scale. You can
do this by clicking on the Genr Button and writing the equation as
below: Click OK, then you will see that a new time series logRP is
generated. Repeat the above to generate logRD, logRE as
log-transformation of RD, log-transformation of RE, respectively. Note
that, if you run the regression model of logRP on logRD, logRE, the
slope coefficients represent the elasticity between the stock price and
the explanatory variables (dividend and earning). For example, a slope
coefficient on logRD should be interpreted as the percentage change of
RP with respect to 1% change of RD or elasticity of RP with respect to
RD. You are suggested to save your file at this stage by clicking the
Save Button. 4 Assignment (Answer All Questions) Question 1 [Total 10
marks] a) Report the time plots and SACF of the time series in according
to level series data (logRP, logRD, and logRE). [5 marks] b) Based on
these measures, provide a summary of the descriptive properties of these
time series in relation to their main components, dependence structure,
and stylized features of financial time series. [5 marks] Question 2
[Total 10 marks] a) Report time plots and SACF of the time series in
first difference (logRP, logRD, and logRE). [5 marks] b) Based on
these measures, provide a summary of the descriptive properties of these
time series in relation to their main components, dependence structure,
and stylized features of financial time series. [5 marks] Note: In
Eviews, you can use d(X) to represent the first difference of X.
Question 3 [Total 10 mark] a) Find the best fitting ARMA models for
logRP, logRD, and logRE, justifying your final chosen models with
appropriate statistical measures or tests. [6 marks] b) Using these
models, generate dynamic (out-of-sample) forecasts for the next 12 month
for logRP, logRD, and logRE. Evaluate the accuracy of the forecasts
using the MAPE. [4 marks] 5 Question 4 [Total 10 marks] Conduct the ADF
test for logRP, logRD, and logRE,; and determine whether they are I(2),
or I(1), or I(0). Question 5 [Total 10 marks] Regardless of your test
outcomes in Question 4, let us assume that all of these time series are
of I(1). a) Run the regression of logRP against logRD, and logRE
(including the intercept term). [3 marks] b) Conduct the test for
cointegration using the ADF test. [3 marks] c) Depending on the outcome
of the test, interpret the long-run relationship implied by the
regression results. [4 marks] Notes: In Eviews, the residuals from a
regression are stored in the variable called resid, after you run the
regression. Hence, straight after you run the regression, click Genr and
write e = resid before you click OK. Then, the residuals from the
regression are stored in the variable called e. The critical values for
the unit root test for the residuals are given in the lecture notes. If
you find the time series to be co-integrated in Question 5, estimate the
following error- correction model: ∆ log = 1 + 1−1 + 1∆ log −1 + 2∆ log
−1 + 3∆ log−1 + 1 ∆ log = 2 + 2−1 + 4∆ log −1 + 5∆ log−1 + 6∆ log −1 + 2
∆ log = 3 + 3−1 + 7∆ log −1 + 8∆ log −1 + 9∆ log −1 + 3 where e
represents the residual from the co-integrating regression. If you find
the time series not to be co-integrated, estimate the following
short-run model: ∆ log = 1 + 1∆ log −1 + 2∆ log −1 + 3∆ log −1 + 1 ∆ log
= 2 + 4∆ log −1 + 5∆ log−1 + 6∆ log −1 + 2 ∆ log = 3 + 7∆ log −1 + 8∆
log −1 + 9∆ log −1 + 3 In Eviews, Xt-1 is be represented as d(X(-1));
and Xt-1 as X(-1). 6 Question 6 [Total 10 marks] Interpret the
estimation results of the above short-run models, paying attention to a)
Speed of adjustments to long-run equilibrium (if logRP, logRD, and
logRE are co- integrated); [4 marks] b) Whether the past changes of RD,
and/or RE have explanatory power (or predictive ability) for the current
change of RP; [4 marks] c) Whether the past changes of RP have
explanatory power (or predictive ability) for the current change of RP.
[2 marks] Note: Interpret the estimated coefficients and their economic
significance and conduct the t-test on βj’s to evaluate the statistical
significance. Question 7 [Total 10 marks] Provide a non-technical
summary of your findings from Questions 1 to 6, in less than 200 words.
Your discussion should include how the current stock return is affected
by the past values of dividend changes and/or stock return, economically
and statistically. 7 Reference List Fabozzi, F.J., Focardi, S. M.,
