This paper develops and empirically examines a model of relative productivity differences both within and across industries for small open economies. We decompose the effect of industry productivity on export performance into direct effect of own-firm productivity and an indirect effect of...

We estimate the effect of interstate highways on the level and composition of trade for US cities. Highways within cities have a large effect on the weight of city exports with an elasticity of approximately 0.5. We find little effect of highways on the total value of exports. Consistent with...

This paper examines the effect of labor coercion on human capital accumulation. We use micro data from Puerto Rico, where unskilled laborers were forced to work for landowners during 1849–1874. Using variation in municipality-level suitability for coffee cultivation and international coffee...

This paper examines the impact of China's falling import tariffs on the organization of exports between ordinary and processing trade. These trade forms differ in terms of tariff treatment and the ability of firms to sell on the domestic market. At the industry level, we find that falling input...

Models of comparative advantage are usually based either on differences in factor abundance or differences in total factor productivity within a country despite considerable empirical evidence that both matter. This paper articulates a unified and tractable model in which comparative advantage...

This paper derives and estimates a unified and tractable model of comparative advantage due to differences in both factor abundance and relative productivity differences across industries. It derives conditions under which ignoring one force for comparative advantage biases empirical tests of...

Why did Victorian Britain invest so much capital abroad? We collect over 500,000 monthly returns of British and foreign securities trading in London and the United States between 1866 and 1907. These heretofore-unknown data allow us to better quantify the historical benefits of international...

The structure of protection across sectors has been interpreted as the result of competition among lobbies to influence politicians, but lobbies have been treated as unitary decision makers and little attention has been devoted to the importance of individual firms in this process. This paper...

Do lobbyists provide issue-specific information to members of Congress? Or do they provide special interests access to politicians? We present evidence to assess the role of issue expertise versus connections in the US Federal lobbying process and illustrate how both are at work. In support of...
