This paper analyzes the demand and cost structure of the French market of academic journals, taking into account its intermediary role between researchers, who are both producers and consumers of knowledge. This two sidedness feature will echoes similar problems already observed in electronic...

Economists and sociologists disagree over markets’ potential to take over functions typically performed by networks of personal connections. First among them is the reliable transmission of information. In this paper we begin from a model of labour markets where social ties are stronger...

This paper models how migration both influences and responds to differences in disease prevalence between cities, regions and countries, and show how the possibility of migration away from high-prevalence areas affects long-run steady state disease prevalence. We develop a dynamic framework...

We study infrequent durables stock adjustment by consumers who also derive utility from non-durable consumption flows, in the presence of idiosyncratic income uncertainty. We first characterize how the extent of uncertainty bears theoretically on the cross-sectional distribution of the...

The expansion of the EC to include EFTA countries, and the greater provision of preferential access to protected EC markets for farmers in Eastern Europe's economies in transition, would have opposite effects on Europe's excess supply of food and on international food prices (assuming EC...

This paper presents a modified and improved methodology for the decomposition of wage differentials between two groups of workers into an endowment component and a discrimination component. The standard decomposition technique does not take into account different probabilities of entering the...

This paper compares adversarial with cooperative industrial and trade policies in a dynamic oligopoly game in which a home and foreign firm compete in R&D and output and, because of spillovers, each firm benefits from the other’s R&D. When the government can commit to an export subsidy, such a...

We recalibrate den Haan, Haefke, and Ramey's matching model to incorporate our preferred specification of 'turbulence' as causing distinct dynamics of human capital after voluntary and involuntary job losses. Under our calibration, with high unemployment benefits, an increase in turbulence...

Since the Middle Ages the Jews have been engaged primarily in urban, skilled occupations, such as crafts, trade, finance and medicine. This distinctive occupational selection occurred between the seventh and the ninth centuries in the Muslim Empire and spread to other locations. We argue that...

This paper uses a three-factor (capital, low- and high-skill labour), two-household (low- and high-skill individuals), two-sector trade model to analyse the determinants of voter attitudes towards immigration under direct democracy and identify factors that would be coherent with both the...
