The expanding literature on lying has exclusively considered lying behavior within a one-dimensional context. While this has been an important first step, many real-world contexts involve the possibility of simultaneously lying in more than one dimension (e.g., reporting one’s income and...

The explosion in online social networks motivates an enquiry into their structure and their welfare effects. A central feature of these networks is information sharing: online social networks lower the cost of getting information from others. These lower costs affect the attractiveness of...

A pervasive feature in the finance industry is relative performance, which can include extrinsic (money), intrinsic (self-image), and reputational (status) motives. In this paper, we model a portfolio decision with two assets and investigate how reputational motives (i.e., the public...

Theoretical models on network formation focus mostly on the stability and efficiency of equilibria, but they cannot deliver an understanding of why specific equilibrium networks are selected or whether they are all actually reachable from any starting network. To study factors affecting...

We develop a model of social preferences for network games and study its predictions in a local public goods game with multiple equilibria. The key feature is that players' social preferences are heterogeneous. This gives room for disagreement between players about the "right" payoff ordering....

Central banks have become increasingly communicative. An important reason is that democratic societies expect more transparency from public institutions. Central bankers, based on empirical research, also believe that sharing information has economic benefits. Communication is seen as a way to...
