Dynamic Rent, Corporate Political Expenditure, and Normative Corporate Income Tax
The 1984-2017 accounting data of 234 companies registered on the US S & P 500 were used to calculate the dynamic rents of these companies. From this, the normative corporate tax rate time series was calculated. We also analyzed the correlation between political spending and rent from this rent time series and the time series of lobbying data from the LDA report. We also analyzed the relationship between R & D and rent for 73 companies that can use R & D data.
