ANSWERS TO DATA ANALYSIS PROBLEMS
1. Go to the St. Louis Federal Reserve FRED database and find data on house prices
(SPCS20RSA), stock prices (SP500), a measure of the net wealth of households
(TNWBSHNO), and personal consumption expenditures (PCEC). For all four measures, be
sure to convert the frequency setting to “Quarterly.” Download the data into a spreadsheet,
and make sure the data align correctly with the appropriate dates. For all four series, for
each quarter, calculate the annualized growth rate from quarter to quarter. To do this, take
the current-period data minus the previous-quarter data, and then divide by the previous
quarter data. Multiply by 100 to change each result to a percent, and multiply by 4 to
annualize the data.
a. For the four series, calculate the average growth rates over the most recent four quarters
of data available. Comment on the relationships among house prices, stock prices, net
wealth of households, and consumption as they relate to your results.
See table below. From the most recent available data from 2016:Q2 to 2017:Q1, all four
data series are showing healthy gains, and are sensibly related to each other. Since
b. Repeat part (a) for the four quarters of 2005, and again for the period from 2008:Q3 to
2009:Q2. Comment on the relationships among house prices, stock prices, net wealth of
households, and consumption as they relate to your results, before and during the crisis.
See table below. The period prior to the financial crisis, and the crisis period itself are
starkly different. In the 2005 period, house prices were rising quickly, and stock prices

c. How do the current household data compare to the data from the period prior to the
financial crisis, and during the crisis? Do you think the current data are indicative of a
bubble?
The most current data overall shows strong growth in these household indicators
somewhat similar to the pre-crisis period in 2005, although in the most recent period

2. Go to the St. Louis Federal Reserve FRED database and find data on corporate net worth of
nonfinancial businesses (TNWMVBSNNCB), private domestic investment (GPDIC1), and a
measure of financial frictions, the St. Louis Fed financial stress index (STLFSI). For all three
measures, be sure to convert the frequency setting to “Quarterly.” Download the data into a
spreadsheet, and make sure the data align correctly with the appropriate dates. For
corporate net worth and private domestic investment, calculate the annualized growth rates
from quarter to quarter. To do this, take the current-period data minus the previous-quarter
data, then divide by the previous quarter data. Multiply by 100 to change the results to
percentage form, and then multiply by 4 to annualize the data.
a. Calculate the average growth rates over the most recent four quarters of data available
for the corporate net worth and private domestic investment variables. Calculate the
difference between the value of the stress index during the most recent quarter and the
value of the stress index one year earlier. Comment on the relationships among financial
stress, net wealth of corporate businesses, and private domestic investment.
See table below. The most recent four quarters available from 2016:Q2 to 2017:Q1
indicates that financial frictions as measured by the stress index have fallen slightly, and
b. Repeat part (a) for the four quarters of 2005 and for the period from 2008:Q3 to
2009:Q2. Comment on the relationships among financial stress, net wealth of corporate
businesses, and private domestic investment before and during the crisis as they relate to
your results. Assuming the financial stress measure is indicative of heightened
asymmetric information problems, comment on how the crisis-period data relate to the
typical dynamics of a financial crisis.

financial crisis, and during the crisis? Do you think the current data are indicative of a
