We show that exported products exit the US market sooner if they violate the Heckscher-Ohlin notion of comparative advantage. Crucially, this pattern is stronger when exporting country has a well-developed banking system, measured by a high ratio of bank credit over the GDP. Banks thus push...

With global specialization and trade, countries make directly but also indirectly use of the environment via traded goods. Based on the theory of comparative advantages, the Heckscher-Ohlin-Vanek approach, we are using the Ecological Footprint as a broad measure of environmental use because its...

We illustrate a new source of comparative advantage that is generated by countries' different ability to adjust to technological change. Our model introduces substitution of workers in codifiable (routine) tasks with more efficient machines, a process extensively documented in the labor...

The trade literature often treats countries as dimensionless points, which is a strong assumption. Agglomeration or lumpiness of production factors within countries can affect the national pattern of trade. In this paper we analyze comparative advantage patterns for 22 cities and 4 regions for...

Based on the Heckscher-Ohlin-Vanek (H-O-V) theory, the paper develops theoretical models that lead to estimating cross-industry equations in a proper way, when allowing for departures from some of the strong assumptions of the H-O theory, such as perfect competition, equal factor unit...

The Heckscher-Ohlin theory and the Ricardian theory of international commerce traditionally have been treated as separate conceptual frameworks, but a growing body of empirical work is relying on both simultaneously and calls for an integrated theory. This paper combines the Heckscher-Ohlin...

We develop a dynamic general equilibrium trade model with comparative advantage, heterogeneous firms, heterogeneous workers and endogenous firm entry to study wage inequality during the adjustment after trade liberalization. We find that trade liberalization increases wage inequality both in the...

This paper studies the origins and consequences of international technology gaps. I develop an endogenous growth model where R&D efficiency varies across countries and productivity differences emerge from firm-level technology investments. The theory characterizes how innovation and learning...
