Social Networks and Interactions in Cities

Helsley, Robert W. - 2011

We examine how interaction choices depend on the interplay of social and physical distance, and show that agents who are more central in the social network, or are located closer to the geographic center of interaction, choose higher levels of interactions in equilibrium. As a result, the level...

Burks, Stephen V. - 2010

relatively. We test three different theories about observed relative overconfidence. The first theory notes that simple … on 1,016 individuals' relative ability judgments about two cognitive tests rejects the Bayesian model. The second theory … might make this belief worse. Our data also reject this prediction. The third theory is that overconfidence is induced by …

Towards a General Theory of Peer Effects

Boucher, Vincent; Rendall, Michelle; Ushchev, Philip; … - 2023

There is substantial empirical evidence showing that peer effects matter in many activities. The workhorse model in empirical work on peer effects is the linear-in-means (LIM) model, whereby it is assumed that agents are linearly affected by the mean action of their peers. We develop a new...
