I consider how heterogeneity in capital goods affects international trade patterns, and I show a novel source of comparative advantage: the magnitude of capital goods heterogeneity. Capital goods are heterogeneous in their vintage and productivity, and due to capacity constraints, only...

Development accounting shows that a significant part of cross-country income differences is attributed to differences in total factor productivity (TFP), but the sources of TFP differences are not well understood. This paper considers the role of international trade to explain cross-country...

This paper provides a welfare comparison of a tariff with a combination of a production subsidy to, and a commodity tax on, an import-competing commodity in a two-country economy. We treat some plausible situations of industry protection, including where the initial tariff is above the optimal...

We introduce technological differences in a Heckscher-Ohlin model and study how the technology and endowment differences interact to determine the effects of trade on factor prices.
