Many economic and social networks share two common organizing features: (1) a core-periphery structure; (2) positive correlation between network centrality and payoffs. In this paper, we build a model of network formation where these features emerge endogenously. In our model, the unique...

Gagnon and Goyal (2017) develop an elegant model to understand the interaction between community and markets. One key argument is that, among others, whether markets and social ties are substitutes or complements plays a decisive role: markets undermine social ties in the case of substitutes and...

In their quest to maximize efficiency, law and economics scholars often produce novel, creative, and counterintuitive legal rules. Indeed, legal economists have argued for baby selling, against anti-discrimination laws in the workplace, and for insider trading. In this essay, we discuss some...

This paper employed a widely accepted theoretical concept, the 'theory of migrant networks' to look at the recent immigration and absorption experience of ethnic Germans (Aussiedler) from Eastern Europe and the former Soviet Union in Germany. Consistent with network theory, the social background...

The current study assesses the effects of immigration control on the welfare of the current and future population of a host economy. A theoretical model of a small open economy populated with overlapping generations of heterogeneous agents is used to show that skill-favouring immigration...

According to the literature, well known tariff reform rules that are guaranteed to increase welfare will not necessarily increase market access, while rules that are guaranteed to increase market access will not necessarily increase welfare. Such conflict between welfare and market access...

Merchant guilds have been portrayed as social networks that generated beneficial social capital by sustaining shared norms, effectively transmitting information, and successfully undertaking collective action. This social capital, it is claimed, benefited society as a whole by enabling rulers to...

Participation rates in most means-tested welfare programs in the United States are low. Many low-income individuals refrain from using welfare benefits available for them, although their value of such benefits is presumably high. This Article studies the causes of forgone welfare benefits...

This paper focuses on the climate change challenge faced by Central & Eastern European countries both those inside the European Union and those outside it. They have enormous energy intensity and associated greenhouse gas (GHG) emissions, mainly from energy production, which is oil, and worse,...

A significant fraction of the labor force consists of employed workers who are part-time unemployed (underemployed) in the sense that they are unable to work as much as they prefer. This paper develops a search and matching model to study the design of optimal unemployment insurance in an...
