Table XI summarizes the results of annual regressions for both Acquisition Count and the Acquisition Ratio in year t on G (or a Democracy dummy), the log of size, the log of the book-to market ratio, and 48 industry dummies, all measured at year-end t -
1. Coefficients on all control variables are omitted from the table. Since many firms make no acquisitions in a year, the dependent variables are effectively left-censored at zero. To account for this censoring, we estimate Poisson regressions for Acquisition Count and Tobit regressions for the Acquisition Ratio. Columns (1) and (3) give results for the full sample, with G as the key regressor; columns (2) and (4) give results for the sample restricted to firms in the Democracy and Dictatorship Portfolios,with a Democracy dummy as the key regressor. For both sets of regressions, the coefficients on G are positive in every year, and the average coefficient on G is positive and significant. Consistent with this result, the average coefficient on the Democracy dummy
is negative for both sets of regressions and is significant for Acquisition Count.
