The daily changes in the closing price of stock follow a random
walk. That is, these daily events are independent of each other and
move upward or downward in a random matter and can be approximated
by a normal distribution. Let's test this theory. Use either a
newspaper, or the Internet to select one company traded on the
NYSE. Record the daily closing stock price of your company for the
six past consecutive weeks (so that you have 30 values)....

The random walk model was first used in physics but has also
been applied to stock prices, psychology, and even game changes in
sports. What other applications can be found for the random walk
model?

positively related; (III) successive price changes are negatively
related; (IV) the autocorrelation coefficient is zero

Theoretically, should the dividend discount model and
free cash flow model yield the same stock price? Explain. What are
the advantages and disadvantages of the free cash flow valuation

You read in a magazine that economic theory suggests the price
of gold should be the same in every country. Describe the theory
from international finance that links prices across countries.
Explain three reasons why you might not expect this theory to hold
in practice.

According to Hall, consumption spending follows a random walk.
1. What determines changes in consumption in this case? 2. What is
the implication of following a random walk for predicting changes
in consumption? What is the impact on current consumption of a
temporary tax cut according to: 3. the Keynesian consumption
function? 4. the permanent-income hypothesis?

Consider the following three models that a researcher suggests
might be a
reasonable model of stock market prices
yt = yt−1 + ut
yt = 0.5yt−1 + ut
yt = 0.8ut−1 + ut
(a) What classes of models are these examples of?
(b) What would the autocorrelation function for each of these
processes look
like? (You do not need to calculate the acf, simply consider what
shape it
might have given the class of model from which it is drawn.)...
