How likely is trade liberalization to produce efficiency gains in the presence of imperfect competition, scale economies, and higher-than-average wages in the modern sectors -- all common features of developing economies? These features create a potential conflict to the extent that traditional...

We study a simple, tractable model of labor adjustment in a trade model that allows us to analyze the economy's dynamic response to trade liberalization. Since it is a neoclassical market-clearing model, we can use duality techniques to study the equilibrium, and despite its simplicity a rich...

This paper assembles elements that are essential in forming an integral picture of the way a churning' economy functions and of the disruptions caused by transactional difficulties in labor and financial markets. We couch our analysis in a stochastic equilibrium model anchored with US evidence...

This paper develops a general theory of aggregation in inefficient economies. We provide non-parametric formulas for aggregating microeconomic shocks in economies with distortions such as taxes, markups, frictions to resource reallocation, financial frictions, and nominal rigidities. We allow...

Uneven development within countries suggests that domestic trade frictions are important. Trade flows within a country, however, are rarely observed. We employ a new dataset on trade between fifteen Chinese treaty ports to examine the importance of domestic frictions around the year 1900. The...

A theoretical model is developed and applied to the North American auto industry, motivated by the possibility of US-Mexico free trade. Special features of the model include (1) significant scale economies at the plant level, (2) imperfect competition among firms, (3) joint ownership of plants...

Permanent shocks such as trade liberalizations are hard to discuss in a standard dynamic Hechscher-Ohlin model due to potential interest rate over-determination. We make three contributions. First, we introduce an endogenous discount factor which solves the problem of interest rate...
