The aim of this paper is to provide a new mechanism based on social interactions explaining why minority workers have worse labor-market outcomes than majority workers. Building on Granovetter's idea that weak ties are superior to strong ties for providing support in getting a job, we develop a...

Evidence from psychology suggests that overconfidence is more important in North America than in Japan. The pattern is reversed for shame, an emotion that appears to play a more important role among Japanese than North Americans. We develop a model that endogenizes these differences, building on...

We study how the prevailing internal organization of the family affected the initial design of pension systems. Our theoretical framework predicts that, in society with weak family ties, pensions systems were introduced to act as a safety net, while in societies with strong ties they replicate...

We develop two different social network models with different economic foundations. In the local-aggregate model, it is the sum of friends' efforts in some activity that affects the utility of each individual while, in the local-average model, it is costly to deviate from the average effort of...

We consider a linguistically diversified society that has to select a set of official languages. We examine the notion of language disenfranchisement that is created when one or more languages fail to be included in the list of the official ones, implying that some individuals are denied full...

For example, the pride associated with...

This paper examines the emergence and dynamics of border effects over time. We exploit the unique historical setting of the multinational Habsburg Empire prior to the Great War to explore the hypothesis that border effects emerged as a result of persistent trade effects of ethno-linguistic...

We investigate how vertical unity within a community interacts with horizontal class divisions of an unequal income distribution. Community is conceptualized in terms of a public good to which all those in the community have equal access, but from which outsiders are excluded. We formulate the...

The European Union has recently expanded from 15 to 25 countries. In line with this enlargement, the list of official EU languages has grown from 11 to 20. Currently, the EU extends equal treatment to all member countries’ official languages by providing translations for documents and...

From the end of the second century C.E., Judaism enforced a religious norm requiring any Jewish father to educate his children. We present evidence supporting our thesis that this exogenous change in the religious and social norm had a major influence on Jewish economic and demographic history....
