We derive and discuss a general, but simple geographical economics model with congestion, allowing us to explain the economic viability of small and large locations. The model generalizes some previous work and lends itself to analyzing the impact of public policy in terms of infrastructure...

We introduce a simple but flexible analytical framework in which both trade in goods and trade in tasks arise. We use this framework to provide versions of the gains-from-trade and the famous four HO theorems (Heckscher–Ohlin, factor-price-equalisation, Stolper–Samuelson, and Rybczynski)...

We develop a model for analyzing the distributional effects of two globalizations and their interdependence. We distinguish between two trade cost reductions, (i) trade liberalizations in the 1980s, which increased trade in low-skill-intensive goods (denoted L-globalization) and (ii) reductions...

This paper derives a micro-founded gravity equation based on a translog demand system that allows for flexible substitution patterns across goods. In contrast to the standard CES-based gravity equation, translog gravity generates an endogenous trade cost elasticity. Trade is more sensitive to...

Estimates of labor mobility costs are needed to assess the responses of employment and wages to trade shocks when factor adjustment is costly. Available methods to estimate those costs rely on panel data, which are seldom available in developing countries. We propose a method to estimate...

We depart from the trade and wages literature and its emphasis on North-South trade, examining North-North by developing the basic linkages between trade-based integration and relative wages in an Ethier-type division of labor model. Using this model we identify a formal relationship between...

We develop a model of international trade between two symmetric countries that features inter-group inequality between managers and workers, and also intra-group inequality within each of those two groups. Individuals are heterogeneous with respect to their managerial ability, and firms run by...

This paper studies how a country's labor market institutions, by affecting workers' skill acquisition, can shape its export patterns. I develop an open-economy model in which workers undertake non-contractible activities to acquire firm-specific skills on the job. In the model, labor market...

This paper investigates a theoretical mechanism linking comparative advantage to the distribution of skills in the working population. We develop a tractable multi-country, multi-industry model of trade with unobservable skills in the labour market and show that comparative advantage derives...
