Interindustry flows, non-traded intermediate goods and the theory of effective protection: A general equilibrium analysis

Abstract

This paper examines the response of net and gross outputs of tradeable goods to changes in tariff structure in the context of a comprehensive general equilibrium model with interindustry flows and non-traded, as well as imported, intermediate goods. There are two major results. First, the nominal rate of tariffs on a tradeable good is shown to correctly indicate the movements of its net output under most general conditions. Second, the (modified and) generalized Corden index of effective protection for a tradeable good is revealed to be in a close relationship with the behavior of its gross output under certain restrictions on the input substitutability of industries.
