2. A large share of household wealth is held in the form of corporate stock. How much wealth does the entire stock market represent? To find an approximate answer, go to the Web site for Wilshire Associates at www.wilshire.com and click Indexes from the menu. Locate the information that explains how the Wilshire 5000 Index is constructed. This index is weighted by the market capitalization of the firms included in it, such that if you add the right amount of zeros to the index, you obtain the total value of all the firms represented in the index. Why is this number a good approximation to the entire U.S. stock market? Now obtain a chart for the index. How much stock market wealth has been created or destroyed over the past 12 months? Determine how much stock market wealth was created or lost per person in the United States over this period. (Hint: You can find the U.S. population at census.gov/main/www/ popclock.html). Compare this with the average after-tax annual income per person in the United States. Use the disposable personal income figure that can be found under "Selected NIPA Tables: Table 2.1" at bea.gov/national/ nipaweb/Index.asp to make the comparison.
