Abstract

We explore the cyclical pattern of trade protection in a simple New Keynesian open economy macro model. Tariff rates are determined endogenously in a sustainable equilibrium of a two-country trade policy game. The incentive to levy tariffs is greater when the exchange rate is floating, since a fixed exchange rate removes the ability to manipulate the terms of trade. If prices are fully flexible, we find that protectionism is basically acyclical. By contrast, with pre-set prices, tariffs respond to both monetary and productivity shocks. But the degree of protection may be pro-cyclical or counter-cyclical, depending on the pattern of shocks and parameter values.
