This paper examines whether differences in welfare regimes shape the incentives to work and get educated. Using microeconomic data for more than 100,000 European individuals, the results show that welfare regimes make a difference for wages and education. First, people- and household-based...

What is the impact of low-wage countries' competition on the quality of high-wage countries' exports? To answer this question, we develop a new method that uses firm-level data to measure quality changes in sectoral exports. Over 1995-2005, we measure a 11% increase in the mean quality of...

Pairwise stability (Jackson and Wolinsky, 1996) is the standard stability concept in network formation. It assumes myopic behavior of the agents in the sense that they do not forecast how others might react to their actions. Assuming that agents are farsighted, related stability concepts have...

This paper uses a structural, large dimensional factor model to evaluate the role of 'news' shocks (shocks with a delayed effect on productivity) in generating the business cycle. We find that (i) existing small-scale VECM models are affected by 'non-fundamentalness' and therefore fail to...

We analyze delinquent networks of adolescents in the United States. We develop a theoretical model showing who the key player is, i.e. the criminal who once removed generates the highest possible reduction in aggregate crime level. We also show that key players are not necessary the most active...

All Courts rule ex-post, after most economic decisions are sunk. This might generate a time-inconsistency problem. From an ex-ante perspective, Courts will have the (ex-post) temptation to be excessively lenient. This observation is at the root of the principle of stare decisis. Stare decisis...

We consider a small open economy that faces a commitment problem in trade liberalization. We examine how the relationship with a large trading partner affects the ability of the small countrys government to sustain free trade through a reputational mechanism. If the small country's government is...

Using data from the European Social Survey on most European countries, we look at the relationship between ethnic identity and employment prospects for immigrants from non-European countries. We find that a strong attachment to religion is associated with a lower probability of being employed....

We explore the pricing of variance risk by decomposing stocks' total variance into systematic and idiosyncratic return variances. While systematic variance risk exhibits a negative price of risk, common shocks to the variances of idiosyncratic returns carry a large positive risk premium. This...

Communal responsibility, a medieval institution studied by Greif (2006), supported the use of credit among European merchants in the absence of modern enforcement technologies. This paper shows how this mechanism helps to overcome enforcement problems in anonymous buyer/seller transactions. In a...
