We combine information on social networks with medical records and survey data in order to examine how friends affect one’s decision to get vaccinated against the flu. The random assignment of undergraduates to residential halls at a large private university allows us to estimate how peer...

There is a longstanding concern that material incentives might undermine prosocial motivation, leading to a decrease in blood donations rather than an increase. This paper provides an empirical test of how material incentives affect blood donations in a large-scale field experiment spanning...

Firms often face choices about when to upgrade and what to upgrade to. We discuss this in the context of upgrading to a new technology (for example, a new computer system), but it applies equally to the upgrading of processes (for example, a new organizational structure) or to individual choices...

Evidence from social psychology suggests that agents process information about their own ability in a biased manner. This evidence has motivated exciting research in behavioral economics, but also garnered critics who point out that it is potentially consistent with standard Bayesian updating....

The theme of communication leads to major changes in the way of conceptualizing the world and human behavior. The communication process turns into the game, and how everything is put into communication “without limits” (Codoban, 1995) everything is a game. Transforming reality into a...

We study a general class of models with social interactions that might display multiple equilibria. We propose an estimation procedure for these models and evaluate its efficiency and computational feasibility relative to different approaches taken to the curse of dimensionality implied by the...

This paper celebrates the life and contributions of Gary Becker (1930-2014).

This article reviews the most important transfers of this kind into evolutionary economics. It broadly differentiates between approaches that draw on an analogy construction to the biological sphere, those that make metaphorical use of Darwinian ideas, and avenues that are based on the fact that...
