(20 points) The following questions are regarding the Fama-Macbeth regression: A (15 points) Suppose that you have the data of stock returns on 2000 stocks since in a market (1000 since 01/1990 and another 1000 since 01/2000), the risk-free rates, and market returns from 01/1990 to 12/2019. All data are on the monthly basis. Now, you have an assignment to examine the explanatory power of the idiosyncratic volatility for individual stock returns, applying the Fama-Macbeth regressions. The idiosyncratic volatility (the standard deviation of the residuals under the CAPM) are estimated using the past 3- year monthly returns, with at least 12 observations. Describe EVERY detail of your steps. Remember to mention the numbers of required regressions and observations in each step.)
