In this assignment you are asked to replicate selected and slightly modified parts
of the article "Bank CEO Incentives and the Credit Crisis" by Fahlenbrach and
Stulz, Journal of Financial Economics, 2011 (in the following referred to as "FS").
For this assignment you will need to use four databases, ExecuComp (to compute
CEO incentives), CRSP (to construct buy-and-hold returns), the CRSP-Compustat
Merged Database (for standard accounting data), and the Compustat Bank
Fundamentals Annual Database (for the tier 1 capital ratio). Start from the entire
ExecuComp dataset (CEOs only), and apply the sample selection criteria given in
Section 2 of the article. Then compute three measures of CEO incentives: First,
"Percentage of equity-based pay". This is fair dollar value of option awards plus
the fair dollar value of stock awards, all divided by total compensation. Second,
"Percentage ownership", defined as the number of shares and options held by
the CEO (vested as well as unvested ones), divided by the total number of shares
outstanding. (Note that this definition differs from that used in the article.) And
third, "Dollar gain from +1%", defined as the natural log of the dollar change in
the value of the CEO's portfolio of current and prior grants of shares and options
for a 1% change in stock price. As an approximation for this variable, use the
natural log of the variable ONEPCT as defined in equation (8) in Bergstresser and
Philippon (2006). (The paper is available on the Blackboard page for this
assignment.)
Next, merge in accounting data from Compustat as well as the Tier 1 capital ratio
from the Compustat Fundamentals Annual Database. Finally, construct buy-and
hold returns (BHRs) for the banks analyzed. Buy-and-hold returns for bank i and
period s, starting from time t, are computed as BHRi,t-->t+s= (1+R i,t+1)*(1+R
i,t+2)*…* (1+R i,t+s)-1. Compute these BHRs from CRSP monthly holding period
returns for all banks in your sample, and over the period July 2007 to December
2008. (For each bank you should have one BHR for each calendar month in the
period July 2007 to December 2008). Normalize BHR to zero in July 2007. Note
that, for the plot of question 3, you need to keep one observation for the BHRs
for each bank and month while for the regressions, you only need to retain one
BHR for each bank, i.e. the BHR from July 2007 to December 2008. You will then
need to merge the file containing the buy-and-hold returns with the ExecuCompCompustat–merged file. The merge is somewhat different for question 3 than for
questions 4 and 5 due to the different number of BHRs per bank.Questions:
1. Provide a summary statistics table equivalent to FS's Table 1. You only
need to report the variables Total assets, Total liabilities, Market
capitalization, Net income/total assets, Net income/book equity, Book-tomarket ratio, and Tier 1 capital ratio. Briefly summarize the results and
compare them to those of FS. Do you roughly or exactly match the
numbers in their Table 1?
2. Provide a summary statistics table equivalent to FS's Table 3. You only
need to report the statistics for CEOs, and you only need to report the
following variables: Total compensation, Salary, Bonus, Dollar value of
annual stock grant, Dollar value of annual option grant, Other
compensation, Value of total equity portfolio/total value of annual
compensation, Percentage of equity-based pay, Percentage ownership ,
and Dollar gain from +1% increase in stock price. Note that the fraction of
equity-based compensation is not given in Table 1 of the original paper.
You will use it as an alternative measure of equity incentives.
3. Split the sample in two halves, high and low incentives according to each
of the three measures of incentives, and plot the monthly subsample
average of the buy-and-hold return (y-axis) against monthly calendar
time (x-axis) separately for banks in the two subsamples. (Plot three
graphs (one for each incentive measure) where each graph shows two
lines: one for the upper half and one for the lower half. Briefly describe
the figures, and comment on whether they are consistent with FS's main
hypothesis. (Note that the original article does not contain these figures.)
4. Produce a regression table similar to Table 4 of FS. Report five columns
only: the first three show univariate regressions of buy-and-hold returns
on the three incentive measures, the fourth column is a multivariate
regression including all three incentive measures as independent
variables. The fifth regression contains only one incentive measure, the
one which is most highly significant in regressions (1) to (3) and further
adds the book-to-market ratio and the log of market value. Do you find
that highly incentivized CEOs did better or worse during the crisis?
5. Produce the same regression table as for question 4, except that you now
replace the dependent variable with the tier 1 capital ratio in fiscal year
2006. Did banks with highly incentivized CEOs have less, similar or more
leverage than less incentivized CEOs before the crisis? (Note that the
article does not contain this table.)
For each of the questions, give your answer in two pages. Provide the respective
table or figure(s) including caption on the first page. On the second page,
describe your results in words, i.e. comment on the magnitude of the key
coefficients or statistics (statistical and economic significance), and relate your
results to those in the original paper (are your results similar or different?).
Tables and figures should look like those in the top finance journals (Journal of
Finance, Journal of Financial Economics, Review of Financial Studies). They must
be self-contained, requiring no further information from other sources, including
the main text, to broadly understand them. In particular, the caption must define all variables and briefly explain what the table or figure shows. Use descriptive
names for the variables, not cryptic ones. E.g. use "Book leverage" instead of
"bk_lev".
You need to submit your document in pdf format to the Blackboard course page.
If you create your document in Microsoft Word or another text editor, you need
to convert your file to pdf format before submitting.
In addition to the answers to the questions above, you also need to submit the
STATA code which you used to prepare and analyze the data. Copy and paste the
Stata code into the appendix of the document you submit, so that you upload
only one single pdf file to Blackboard (do not upload dta files to Blackboard!).
The deadline for the assignment is 31 January, 2017, 13:00. The assignment will
be graded on a scale of 1 to 10. It will count for 60% of the final grade. I will use
the following scheme for late sub–missions: For each day of delay, 0.5 grade
points will be subtracted from the grade (i.e. one day late=-0.5pt, two days late=-
1 pts, etc.).
Good luck!
