We analyze the impact of technology on production and trade in services, focusing on the foreign exchange market. We identify exogenous technological changes by the connection of countries to submarine fiber-optic cables used for electronic trading, but which were not laid for purposes related...

This paper is concerned with the fact that the incidence of speculative attacks tends to be temporally correlated; that is, currency crises appear to pass contagiously from one country to another. The paper provides a survey of the theoretical literature, and analyzes the contagious nature of...

Since the early 1980s, the U.S. economy has experienced a growing wage differential: high-skilled workers have claimed an increasing share of available income, while low-skilled workers have seen an absolute decline in real wages. How and why this disparity has arisen is a matter of ongoing...

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...

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...
