Historical records show that the Sicilian mafia initially developed to protect land from predatory attacks, at a time when publicly provided security was scarce and banditry widespread. Using a common-agency model, the Paper shows that: (i) it is optimal for each landowner to voluntarily buy...

We model networks of relational (or implicit) contracts, exploring how sanctioning power and equilibrium conditions change under different network configurations and information transmission technologies. In our model relations are the links, and the value of the network lies in its ability to...

Did living standards stagnate before the Industrial Revolution? Traditional real-wage indices typically show broadly constant living standards before 1800. In this paper, we show that living standards rose substantially, but surreptitiously because of the growing availability of new goods....

We provide a comprehensive empirical analysis of the links between international services outsourcing, domestic outsourcing, profits and innovation using plant level data. We find a positive effect of international outsourcing of services on innovative activity at the plant level. Such a...

Economists are skeptical about the economic benefits of hosting "mega-events" such as the Olympic Games or the World Cup, since such activities have considerable cost and seem to yield few tangible benefits. These doubts are rarely shared by policy-makers and the population, who are typically...

How successful is the theory of the firm in explaining intra-firm trade? To answer this question we exploit a unique dataset of 1,141,393 French import transactions, spanning across firm, countries and products in 1999, and reporting whether a transaction is intra-firm. Overall, we find support...

We study international trade in a model where consumers have non-homothetic preferences and where household income restricts the extensive margin of consumption. In equilibrium, monopolistic producers set high (low) prices in rich (poor) countries but a threat of parallel trade restricts the...

We provide a novel set of stylized facts on firms engaging in international trade in services, using unique data on firm-level exports and imports from the world's second largest services exporter, the United Kingdom (UK). We show that only a fraction of UK firms engage in international trade in...

During the transition from plan to market, managers and politicians succeeded in maintaining control of large parts of the stock of socialist physical capital. Despite the obvious importance of this phenomenon, there have been no efforts to model, measure and investigate this process...

I study the constrained efficient allocations of a simple model of risk sharing and capital flows across countries assuming that each country cannot commit to fully repay its contract obligations. In the model, the degree of risk sharing and the amount of investment are interdependent. It is...
