Our objective is twofold. First, we show why there is a spatial question in economic theory - why a free competitive market is unable to cope with agglomeration and regional imbalance in the absence of market distortions. Second, using a new and simple model, we review what has been accomplished...

We develop a monopolistically competitive model of trade with firm heterogeneity - in terms of productivity differences - and endogenous differences in the 'toughness' of competition across markets - in terms of the number and average productivity of competing firms. We analyze how these...

The global pattern of foreign direct investment (FDI) is quite similar to the world trade pattern. In particular, intraindustry FDI between rich nations is almost as pervasive as intraindustry trade among rich nations. In the standard' MNC model (of Markusen, Venables, Brainard, and others), FDI...

We provide the first detailed quantitative assessment of the effects of the Financial Fair Play Regulation (FFPR) introduced by the Union of European Football Associations (UEFA) on the income statements and balance sheets of European football clubs. While other studies exist documenting the...

Especially in developing countries credit constraints are often perceived as one of the most important market frictions constraining firm innovation and growth. Huge amounts of public money are being devoted to the removal of such constraints but their effectiveness is still subject to an...

We document how demand shocks in export markets lead French multi-product exporters to re-allocate the mix of products sold in those destinations. In response to positive demand shocks, those French firms skew their export sales towards their best-performing products; and also extend the range...

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 frame-work and a number of empirical results that help distinguishing 'good' from 'bad'...

A possible unintended but damaging consequence of anti-immigrant rhetoric, and the policies it inspires, is that they may put high-skilled immigrants off more than low-skilled ones at times when countries and businesses intensify their competition for global talent. We investigate this argument...

Quantifying the effects of trade policy in the age of 'global value chains' (GVCs) requires an enhanced analytical framework that takes due account of the observed international input-output relations. However, the existing quantitative general equilibrium models generally assume that...
