We study how players in a local interaction hawk dove game will learn, if they can either imitate the most succesful player in the neighborhood or play a best reply versus the opponent's previous action. From simulations it appears that each learning strategy will be used, because each performs...

This paper characterizes the set of equilibrium networks in the two-way flow model of network formation with small decay, and this for all increasing benefit functions of the players. We show that as long as the population is large enough, this set contains large- as well as small-diameter...

This paper studies network formation in settings where players are heterogeneous with respect to benefits as well as the costs of forming links. Our results demonstrate that centrality, center-sponsorship and short network diameter are robust features of equilibrium networks. We find that in a...

A monopolist offers a product to a market of consumers with heterogeneous quality preferences. Although initially uninformed about the product quality, they learn by observing past purchase decisions and reviews of other consumers. Our goal is to analyze the social learning mechanism and its...

An increasing proportion of transactions in two-sided markets are being mediated by online platforms. Presumably, agents choose to use online platforms because they have a lower transaction cost technology compared to alternatives. I use data from a growing online platform that matches travelers...

We study a model of collective decision making with endogenous information collection. Agents collect information about the consequences of a project, communicate, and then vote on the project. We examine under what conditions communication may increase the probability that good decisions are...
