The first and third columns of this table present annual OLS and ordered logit regressions of Net insider purchases on G measured in the previous year, SIZE, BM, and a constant. In the second and fourth columns,we restrict the sample to firms in the Democracy (G < 5) and Dictatorship (G > 14) Portfolios and we include as a regressor a dummy variable that equals 1 when the firm is in the Democracy Portfolio and 0 otherwise.The coefficients on SIZE, BM, and the constant are omitted from the table. The calculation of G is described in Section II. Net insider purchases is the sum of split-adjusted open market purchases less split-adjusted open market sales during a year scaled by shares outstanding at the end of the previous calendar year. The
ordered logit regressions use a dependent variable that equals 1 ifiVef insider purchases is positive, 0 if it is zero, and -1 if it is negative. The data on insider sales are from the Thomson database. SIZE is the log of market capitalization in millions of dollars measured at the end of the previous calendar year, and BM is the
log of the ratio of book value (the sum of book common equity and deferred taxes) in the previous fiscal year to size at the close of the previous calendar year. The coefficients and standard errors from each annual cross-sectional regression are reported in each row, and the time-series averages and time-series standard errors are given in the last row. Significance at the 5 percent and 1 percent levels is indicated by * and **,respectively. All coefficients and standard errors are multiplied by 1000.
