We study a screening model in which agents can under-utilize goods. We characterize implementable and optimal contracts and show that, whenever the principal values usage instrumentally, the optimal menu involves multi-part tariffs with tiers of zero marginal prices. We apply our results to...

This paper analyzes some aspects of the effects of trade restrictions (such as tariffs, quotas and quality controls) and their desirability when the quantity of the imported good is endogenous, and the foreign producer is a monopolist. It uses a fairly general model based on the work of Spence...

This paper analyzes the determination of the optimal tariff under the assumption of Consistent Conjectural Variations (CCV). A general characterization of the CCV equilibrium is given. We show that (i) there are, in general, a multiplicity of such equilibria, and (ii) under certain restrictions,...

This paper analyze these effects of a tariff in an intertemporal optimizing model, emphasizing the role of capital accumulation. Three types of increases in the tariff rate are considered: (i) unanticipated permanent; (ii) unanticipated temporary; (iii) anticipated permanent. There are two main...

What does the macroeconomy look like in the aftermath of tariff changes This paper estimates impulse response functions from local projections using a panel of annual data that spans 151 countries over 1963-2014. Tariff increases are associated with persistent, economically and statistically...

We examine the causal effect of tariff uncertainty on firms’ cost of debt. Our tests exploit a unique trade policy that reduces tariff uncertainty on Chinese imports without affecting the actual tariff rate: the U.S.-China Permanent Normal Trade Relations (PNTR). We find a significant drop in...

This paper derives the dependency of optimal tariff and inflation tax on tax collection and enforcement costs. The analysis is done for a small, open economy. The existence of such costs can justify tariff and inflation tax policies as optimal revenue-raising devices. This paper suggests that...
