This paper investigates whether the arrival of managers with export experience, i.e. experience acquired through participation in the export activity of previous employers, is related to firms' international trade status and to what extent this relationship is of a causal nature. We construct a...

We study the impact of regional and sectoral productivity changes on the U.S. economy. To that end, we consider an environment that captures the effects of interregional and intersectoral trade in propagating disaggregated productivity changes at the level of a sector in a given U.S. state to...

We use a comprehensive dataset of French manufacturing firms to study their internal organization. We first divide the employees of each firm into `layers' using occupational categories. Layers are hierarchical in that the typical worker in a higher layer earns more, and the typical firm...

A firm's productivity depends on how production is organized given the level of demand for its product. To capture this mechanism, we develop a theory of an economy where firms with heterogeneous demands use labor and knowledge to produce. Entrepreneurs decide the number of layers of management...

When trade costs are of the iceberg type (Samuelson 1952) and markups are independent of trade costs, relative prices across markets are distorted, but relative prices within markets are not. When trade costs depart from the analytically convenient iceberg type, distortion will also occur within...

In this paper we ask why the gravity model of international trade also work well for foreign direct investment (FDI) flows or multinational production (MP). We propose a model of trade and horizontal FDI, where the subsidiary is allowed to source inputs from the headquarters. Under certain...

We study the role of contract enforcement in shaping the dynamics of international trade at the firm level. We develop a theoretical model to describe how agents build reputations to overcome the problems created by weak enforcement of international contracts. We find that, all else equal,...

Using micro data for Belgium we investigate the relationship between occupational tasks changes and the rise of service trade. We focus the analysis on the extensive margin and look at the heterogeneous proliferation of firms involved in exports and imports of services across sectors...

We develop a new general equilibrium model of monopolistic competition with heterogeneous firms, variable demand elasticity and multiple asymmetric regions, in which trade integration induces wage and productivity changes. Using Canada-US interregional trade data, we structurally estimate a...

In models with heterogeneous firms trade integration has a positive impact on aggregate productivity through the selection of the best firms as import competition drives the least productive ones out of the market. To quantify the impact of firm selection on productivity, we calibrate and...
