In this paper, we examine possible types of network formation among immigrants in the diaspora and between those immigrants and the locals in different countries. We present the model by considering different possible interactions between immigrants and the new society in their host country....

Although the linear-in-means model is the workhorse model in empirical work on peer effects, its theoretical properties are understudied. In this study, we develop a social-norm model that provides a microfoundation of the linear-in-means model and investigate its properties. We show that...

A large literature has studied how peers affect behavior by exploiting the preexisting social network structure only. What if networks rewire in response to changes in the economic environment, such as a randomized intervention? We exploit a unique panel dataset that contains detailed...

Using uniquely rich administrative matched employer-employee data, we investigate the impact of formal network agreements (FNAs) among firms under two perspectives. First, we assess the impact of joining a FNA on several indicators of firm performance, and total factor productivity. Second, we...

We study entrepreneurs' start-up financing from banks and local financiers. An informal network, whose membership cannot be observed by outsiders, conveys the good signals it gets about the hidden types of network entrepreneurs to local financiers, which are then reflected in different loan...

By downplaying externalities, magnifying the cost of moral behavior, or suggesting not being pivotal, exculpatory narratives can allow individuals to maintain a positive image when in fact acting in a morally questionable way. Conversely, responsibilizing narratives can help sustain better...

We consider a model where each individual (or ethnic minority) is embedded in a network of relation-ships and decides whether or not she wants to be assimilated to the majority norm. Each individual wants her behavior to agree with her personal ideal action or norm but also wants her behavior to...

Information asymmetries can prevent markets from operating efficiently. An important example is the labor market, where employers face uncertainty about the productivity of job candidates. We examine theoretically and with laboratory experiments three key questions related to hiring via...

This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The experimental design extends the Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by allowing for agents with lower linking costs or higher benefits to...

We investigate whether and how social ties affect performance in teams by implementing a field experiment in which a sample of undergraduate students are randomly assigned to either teams composed by friends or teams composed by individuals not linked by friendship relationships. Students...
