We show that the more central … minority agents are in the social network, the more they assimilate to the majority culture. We also show that denser networks … tend to favor assimilation so that, for example, it is easier to assimilate in a complete network than in a star …

Specifically, actions are either strategic substitutes or strategic … complements, and participants have either complete or incomplete information about the structure of a random network. Since … for reduced exposure to loss, and 2) uncertainty about the network structure makes it considerably more difficult to …

A large literature has studied how peers affect behavior by exploiting the preexisting social network structure only … unique panel dataset that contains detailed information on the network of informal financial transactions before and after a … structure of the network of informal financial transactions among households. Second, we estimate a panel model of peer effects …

In this paper, we examine possible types of network formation among immigrants in the diaspora and between those … network structure on the country of origin, such as on international trade. We find that when the size of the diaspora is …

We consider a model of network interactions where the outcome of a unit depends on the outcomes of the connected units …. We determine the key network link, i.e., the network link whose removal results in the largest reduction in the aggregate … outcomes, and provide a measure that quantifies the contribution of a network link to the aggregate outcomes, which complements …

We explore network effects on generosity for different network dimensions. To this end we elicit multiple network … matters for friendship ties but that structural network variables are important in all network dimensions. Importantly, these … effects are not invariant across different network dimensions. We also find that individual characteristics are unrelated with …

This paper reports the results of a laboratory experiment on network formation among heterogeneous agents.
