Intermediate goods and the incidence of the corporation income tax

Intermediate goods are introduced into a general equilibrium model of the incidence of the corporation income tax. Several theoretical conclusions about the role of such goods are established. Many well-known propositions about the incidence of the corporation income tax, emanating from models with only final goods, need to be modified. Estimates from U.S. data suggest that if intermediate goods are left out results will be misleading, especially if these goods are a relatively large sector in the economy and possibilities of substituting capital for labor in their production, and of substituting them for other productive factors in the final-good industries, are rather limited.
