This paper analyzes empirically the relationship between civil wars and international trade. We first show that trade destruction due to civil wars is very large and persistent and increases with the severity of the conflict. We then test the presence of two effects that trade can have on the...

This paper develops a model to analyse the implications of firing costs on incentives for R&D and international specialization. The key idea is that, to avoid paying firing costs, the country with a rigid labour market will tend to produce relatively secure goods, at late stages in their product...

Investigations of the effect of quality differences on heterogeneous performance in exporting have been limited by lack of direct measures of quality. We examine exports of French wine, matching the exporting firms to producer ratings from two wine guides. We show that high quality producers...

This paper develops a model of job creation and job destruction in a growing economy with embodied technical progress, that we use to analyze the political support for employment protection legislations such as the ones that are observed in most European countries. We analyze the possibility of...

This paper formulates a discrete-time model to study the effects of firing costs on labour demand by a firm facing linear adjustment costs under serially independent productivity shocks. We show that a rise in firing costs reduces the firm's marginal propensities to hire and fire, and may...

This paper constructs a theoretical model to study the effects on employment of the introduction of flexible labour contracts (i.e. with low firing costs), which occurred in many European countries in the 1980s, which it then tests on Spanish data. The model predicts that such contracts increase...

This paper develops a model of job creation and job destruction in a growing economy with embodied technical progress, that we use to analyze the political support for employment protection legislations such as the ones that are observed in most European countries. We analyze the possibility of...

This paper analyses theoretically and empirically the relationship between trade and war. We show that the intuition that trade promotes peace is only partially true even in a model where trade is beneficial to all, war reduces trade and leaders take into account the costs of war. When war can...

This paper derives the conditions under which fitness-reducing alleles can survive in a long-run stationary equilibrium for a trading population, extending the results in Saint-Paul (2002) for arbitrary systems of sexual reproduction.

This Paper studies how an institution such as markets affects the evolution of mankind. My key point is that the forces of natural selection are made weaker because trade allows people to specialize in those activities where they are strong, and to offset their weaknesses by purchasing adequate...
