Regional productivity differences in the UK and France: from the micro to the macro

We propose a new data resource that attempts to overcome limitations of standard firm-level datasets for the United Kingdom (like the ARD/ABS) by building on administrative data covering the population of UK firms with a...Read more...

The value of managers' export experience: lessons from the Angolan civil war

We investigate how managers help firms grow by entering a new export market. We conduct an event study on the decision to export to Angola using data on Portuguese firms and workers. We evaluate the impact of the presenc...Read more...

On the productivity advantage of cities

Agglomeration externalities are the key factor explaining the existence of cities and their size. However, while the various micro foundations of agglomeration externalities stress the importance of total factor producti...Read more...

Trade, skills and productivity

We examine how firms adjust their production and technology in response to exogenous trade shocks. We develop a model in which revenue TFP can be distinguished from quantity TFP, and where skill upgrading is explicitly e...Read more...

Unraveling firms: demand, productivity and markups heterogeneity

We develop a novel framework that simultaneously allows recovering heterogeneity in demand, quantity TFP and markups across firms while leaving the correlation between the three dimensions unrestricted. We accomplish thi...Read more...

Quantifying the gap between equilibrium and optimum under monopolistic competition

Equilibria and optima generally differ in imperfectly competitive markets. Although this is well understood theoretically, it is unclear how large the welfare distortions are in the aggregate economy. Do they matter quan...Read more...

Productivity and organization in portuguese firms

Using employer-employee matched and firm production quantity and input data for Portuguese firms, we study the endogenous response of productivity to firm reorganizations as measured by changes in the number of managemen...Read more...

Dream jobs

Understanding why certain jobs are `better? than others and what implications they have for a worker?s career is clearly an important but still relatively unexplored question. We provide both a theoretical framework and ...Read more...

The interconnections between services and goods trade at the firm-level

In this paper we study how international trade in goods and services interact at the firm level. Using a rich dataset on Belgian firms for the period 1995?2005, we show that: i) firms are much more likely to source servi...Read more...

Service trade and occupational tasks: an empirical investigation

Using microdata for Belgium, we investigate the relationship between changes in the task content of production and the rise in the number of service exporters. We show that occupational tasks changes display an extremely...Read more...

Spatial frictions

The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We deve...Read more...

The diffusion of knowledge via managers' mobility

Better managers and managerial practices lead to better firm performance. Yet, little is known about what happens when managers move across firms. Does a firm hiring a good manager improve its performance? If yes is ther...Read more...

Distorted monopolistic competition

We characterize the equilibrium and optimal resource allocations in a general equilibrium model of monopolistic competition with multiple asymmetric sectors and heterogeneous firms. We first derive general results for ad...Read more...

Productivity and organization in Portuguese firms

The productivity of firms is, at least partly, determined by a firm's actions and decisions. One of these decisions involves the organization of production in terms of the number of layers of management the firm decides ...Read more...

The Determinants of Intrafirm Trade: Evidence from French Firms

How well does the theory of the firm explain the choice between intrafirm and arms' length trade? This paper uses firm-level import data from France to look into this question. We find support for three key predictions o...Read more...

Productivity and firm selection: quantifying the 'new' gains from trade

We discuss how standard computable equilibrium models of trade policy can be enriched with selection effects. This is achieved by estimating and simulating a partial equilibrium model that accounts for a number of real w...Read more...

Import Competition from and Outsourcing to China: A Curse or Blessing for Firms?
