Book Description
U.S. corporate taxation is not neutral to inflation. Two of its features -- historical cost depreciation and FIFO inventory accounting -- are expected to lower real after-tax corporate cash flows and, thereby, make investment less attractive when expected inflation is elevated. Using Compustat data for 1965-1980 and a difference-in-differences research design, I do not find evidence in support of this hypothesis. I discuss possible explanations for this non-result. In addition, I find a robust effect of statutory tax changes on corporate investment during the Great Inflation. The effect is economically meaningful and consistent with the prior literature: a tax reform that increases firm's cost of capital by 10% lowers investment of affected firms by 2 percentage points of total assets relative to firms not affected by the reform.
