In the second column of Table VIII, we restrict the sample to include only firms in the Democracy and Dictatorship Portfolios. We then estimate (2) using a dummy variable for the Democracy Portfolio. The results are consistent with the previous regressions
on G. The point estimate for 1999 is the largest in the decade,implying that firms in the Democracy Portfolio have a Q that is 56 percentage points higher, other things being equal, than do firms in the Dictatorship Portfolio. This compares with an estimated difference of 19 percentage points in 1990. While the difference in coefficients between 1990 and 1999 is not statistically significant,it is similar to the total EW difference in abnormal returns estimated in Table VII.19 There is no real pattern for the rest of the decade, however, and large standard errors toward the end of
the sample period prevent any strong inference across years.
