We report two information cascade game experiments that directly test the impact of altruism on observational learning. Participants interact in two parallel sequences, the observed and the unobserved sequence. Only the actions of the observed entail informational benefits to subsequent...

Observational learning theories often assume that people's actions can be observed. However, in many naturally-occurring environments, individuals can choose whether to disclose their behavior to others. We provide theoretical analysis of observational learning under optional disclosure...

Our purpose here is to engage in a cross-disciplinary discussion between Austrian economics and social network theory. In particular, we ask what role social networks play in the extended order, in regard to both individual discovery and whether social networks can be the source of widespread...

Homophily is the tendency of people to associate relatively more with those who are similar to them than with those who are not. In Golub and Jackson (2010a), we introduced degree-weighted homophily (DWH), a new measure of this phenomenon, and showed that it gives a lower bound on the time it...

This paper examines how the structure of a social network and the quality of information available to different agents determine the speed of social learning. To this end, we study a variant of the seminal model of DeGroot (1974), according to which agents linearly combine their personal...

We survey the literature on the economic consequences of the structure of social networks. We develop a taxonomy of "macro" and "micro" characteristics of social interaction networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...

This paper studies the effect of social learning on political outcomes in a model of informative campaign advertising. We find that communication networks among voters have important effects on parties' incentives to disclose political information, on voters' learning about candidates running...

People often conform to others either pro-socially or self-interestedly. By conducting modified dictator game experiments where subjects observe others’ behaviors, this study analyzes how observational learning influences subjects’ conforming/non-conforming and pro-social/self-interested...
