In 2006 the CEO of Bear Sterns, James Caynes, received a
compensation
package of $34 million. The following year Bear Sterns cost
$2.7 billion to the
taxpayers. In 2006, the CEO of Lehman Brothers received a
compensation
package of $27 million. On September 15, 2008, Lehman
Brothers filed for
bankruptcy. The collapse of Lehman Brothers is seen by many
as the key
event that sparked the Global Financial Crisis. In 2006, the
CEO of Citigroup,
Charles Prince, received a compensation package of $25
million. Since then
the stock price has fallen from $50 a share to $3.5 a share. The

2. CEO of
Countrywide Financial, Angelo Mozilo, did even better. His
compensation
package was $43 million. Angelo Mozilo and two other top
executives were
charged by the Security and Exchange Commission (SEC) with
fraud.
According to the SEC, from 2005 through 2007, Countrywide
Financial
engaged in an unprecedented expansion of its underwriting
guidelines and
was writing riskier and riskier loans, which these senior
executives were
warned might ultimately curtail the company's ability to sell
them.
Countrywide Financial was the third biggest originator of
subprime mortgages
and the nation's leader in subprime mortgage- backed securities.
The tragedy
is that these individuals did not make decisions that were in
their companies’
best interest. Why? What went wrong? What caused the relation
between the
CEO and the stockholders to go so badly awry? Discuss.

3. An important component of this course is experience with
analyzing
economic data at the managerial level. The computer is a
perfect tool for
manipulating data and performing statistical analyses. While the
focus of BUS
530 is not on learning statistics, this course will utilize and
improve your
computer skills with a computer assignment designed to
illustrate the
interconnections between data, information and managerial
decisions.
The primary software will be Microsoft Excel and the Excel
statistical add-in:
Data Analysis. Microsoft Excel 2010 (and previous versions)
provides a set
of data analysis tools called Analysis ToolPak which you can
use to save
steps when you develop complex statistical analyses. You
provide the data
and parameters for each analysis; the tool uses the appropriate
statistical
macro functions and then displays the results in an output table.
The Analysis
ToolPak is a Microsoft Office Excel add-in program that is
available when
you install Microsoft Office or Excel. To use the Analysis
ToolPak in Excel,
however, you need to load it first. Click the Microsoft Office
Button, and
then click Excel Options. Click Add-Ins, and then in the
Manage box,
select Excel Add-ins. Click Go. In the Add-Ins available box,
select
the Analysis ToolPak check box, and then click OK. (If

4. Analysis ToolPak is
not listed in the Add-Ins available box, click Browse to locate
it.) If you get
prompted that the Analysis ToolPak is not currently installed on
your
computer, click Yes to install it. After you load the Analysis
ToolPak, the Data
Analysis command is available in the Analysis group on the
Data tab.
In the Module 4 SLP assignment you are also asked to estimate
a market
demand or a cost function (your choice) using the tools of
regression analysis
and the regression software outlined above.
The first data set (demand for housing) is used to apply the
hedonic approach
to demand estimation, while the second data set (demand for
cigarettes) is
used to apply the classical approach. Finally, the third dataset
(cost of
electricity) uses a well known dataset to estimate the cost of
electricity
production. In all cases the data is cross-sectional data.
The estimation of demand follows two approaches:
the classical approach, whereby the quantity demanded of a
product is
explained by its own price, the prices of related goods
(complements and
substitutes), income, tastes and preferences, and the size of the
population, among others;
the hedonic approach, whereby the price of an asset (car, house)

5. is
explained by the characteristics of the asset itself (i.e., the price
of housing
depends on the number of bedrooms, the number of bathroom,
the view
from the house (using a dummy variable: 1 = view, 0 = no
view), the
square footage of the house, the square footage of the lot, etc).

Please keep in mind that when you interpret a regression
coefficient, you are
assuming that all the other variables remain constant.
A Note on ANOVA
The ANOVA table is used to test the null hypothesis that all
regression
coefficients (excluding the intercept term) are equal to zero
against the
alternative hypothesis that at least one is different from zero.
This test is
known as the F test for regression. The F test is computed as
follows, under
the assumption that the null hypothesis is true:

13. The F statistics has two sets of degrees of freedom: numerator
(attached to
the Regression SS) and denominator degrees of freedom
(attached to
Residual SS).
Excel computes the F statistic for you in the ANOVA table, and
computes in
the last column the level of significance (p-value). If the level
of significance
of the test is less than 5%, you will reject at the 5% level the
null hypothesis
that all regression parameters are zero. On the other hand, if the
level of
significance is greater than 5%, you will accept (i.e., fail to
reject) the null
hypothesis that all regression parameters are zero.
