Notes: * p<.05; ** p<.01; *** p<.001. Model 1 provides a baseline for comparison and only includes dummy variables to designate the treatment group, all health insurers, and years. Model 2 does not include interactions or lags. Model 3 does not include interactions, and all variables are lagged by one year. Model 4 does not include interactions, and all variables are lagged by two years. Model 5 includes industry-specific interactions, but no lags. Model 6 includes industry-specific interactions, and all variables are lagged by one year. Model 7 includes industry-specific interactions, as well as a retirement dummy. Model 8 includes industry-specific interactions, as well as retirement and year dummies. As compared to specifications used in Does tax deductibility affect CEO pay? The case of the health insurance industry, these results use Compustat's TDC1 variable as a dependent variable, instead of TOTAL_ALT2.
