We develop a unified model embedding different behavioral mechanisms of social interactions and design a statistical model selection test to differentiate between them in empirical applications. This framework is applied to study peer effects in education (effort in studying) and sport...

This paper estimates the intergenerational transmission of trust by studying children of immigrants in 29 European countries with ancestry in 87 nations. There is significant transmission of trust on the mother's side, and the transmission is significantly stronger than on the father's side. The...

We design a laboratory experiment to test for image motives in a setting where decisions signal intelligence to a social audience. Money-maximizing behavior in the experiment sorts subjects by academic ability, as measured by performance on verbal analogy questions, across two levels of question...

This paper recounts the evolution of the Korean keyboard as a case in which the disadvantages of the inherited standard turn into a nonissue with the advancement of auxiliary technologies. The persistence of an inherited standard, when a superior alternative is available, is usually regarded as...

We introduce an order driver market model with heterogeneous traders that imitate each other on a dynamic network structure. The communication structure evolves endogenously via a fitness mechanism based on agents performance. We assess under which assumptions imitation, among noise traders, can...

We examine the optimal disruption of dark (covert and illegal) networks. Of central importance is that an interventionist will generally have incomplete information about the dark network's architecture. We derive the optimal disruption strategy in a stylized model of dark network intervention...

In this paper we analyze the network structure that endogenously emerges in the credit market of the agent-based model of Riccetti et al. (2011), where two kinds of financial accelerators are at work: the “leverage accelerator” and the “network-based accelerator”. We focus on the...

We report experimental evidence on the effect of observability of actions on bank runs. We model depositors’ decision-making in a sequential framework, with three depositors located at the nodes of a network. Depositors observe the other depositors’ actions only if connected by the network....

We investigate the scope for cooperation in a community engaged in repeated interactions. Players seek the help of others and approach them sequentially according to some fixed order. This defines a ranking profile: a list for each player describing the order in which he approaches other players...

Information decay in networks generates two effects. First, it differentiates how well informed different players within the same component are, and therefore how attractive they are to sponsor links to. Second, players may prefer to sponsor links to players they are already connected to. By...
