We adapt the multidimensional poverty methodology to study job quality dynamics using a unique household survey panel for Chile. We use information on wages, type of contract, training and employment duration to build an aggregate job quality index. Panel data allow us to properly separate...

This paper develops a theory of firm selection and growth and embeds it into an international trade framework of balanced growth. I assume that firm-level growth is the result of idiosyncratic productivity improvements while there is continuous arrival of new potential producers. Firms can also...

What is the best way to reduce trade frictions when resources are scarce? To answer this question, we develop a framework that nests previous general equilibrium gravity models and show that the macro-economic implications of these various models depend crucially on two key model parameters,...

We develop a general equilibrium framework to determine the spatial distribution of economic activity on any surface with (nearly) any geography. Combining the gravity structure of trade with labor mobility, we provide conditions for the existence, uniqueness, and stability of a spatial economic...

We explore the impact of vertical specialization - trade in goods across multiple stages of production - on the relationship between trade and international business cycle synchronization. We develop a model in which the degree of vertical specialization is endogenously determined by comparative...

We develop a model monopolistic competition model of trade and multinational production (MP). Firms receive an idiosyncratic productivity vector that is specified from a multivariate distribution and they also face distance related trade and MP costs. Thus, individual firms face a...

We develop a theory of staggered adjustment dynamics in a perfect competition model of trade with a continuum of varieties. New technologies for each variety arrive at a constant rate. The consumer consumes a product produced with a certain technology until an exogenous shock arrives. This shock...

One feature of globalization is that countries are increasingly specialized in either innovation or in production. To understand the forces behind this specialization and its welfare consequences, we develop a monopolistic competition model of trade and multinational production (MP) in which...
