We show in a multi-sector, heterogeneous-firm trade model that the effect of tariffs on entry, especially in the presence of production linkages, can reverse the traditional positive optimal tariff argument. We then use a new tariff dataset, and apply it to a 189-country, 15-sector version of...

In this paper we assess the effects of the MFA/ATC using both world trade and US data after its removal. Previous literature assesses its effects while in operation. The trade data we analyze are consistent with theoretical predictions of more trade volumes, lower product prices, smaller effect...

This paper explores the relationship between exchange rate pass-through and market share for monopolistically competitive exporters. Under fairly general assumptions we show that pass-through should be high for exporters based in a country with a very large share of total destination market...

We argue that trade in intermediate inputs, or 'global production sharing,' is a potentially important explanation for the increase in the wage gap between skilled and unskilled workers in the U.S. and elsewhere. Using a simple model of heterogeneous activities within an industry, we show that...

This paper analyzes the implications of alterative risk assumptions for estimates of the distorting effects of the corporate tax in Canada. These distortions are decomposed into three broad categories: inter-asset distortions; inter-industry distortions; and inter-temporal distortions. Estimates...

This paper discusses efficiency considerations underlying the widespread exemption of food from sales and value added taxes, in contrast to the distributional considerations usually used to justify them, analyzing the implications for tax policy. Although there are increasing returns in both...
