We modify the basic Gehrig (1993) model. In this model, individual agents are either buyers or sellers. They can choose between joining the search market, joining the monopolistic intermediary or remaining inactive. In the search market, agents are randomly matched and the price at which...

We study the role of whistleblowing in the following inspection game. Two agents who compete for a prize can either behave legally or illegally. After the competition, a controller investigates the agents’ behavior. This inspection game has a unique (Bayesian) equilibrium in mixed strategies....

Price stickiness plays a decisive role in many macroeconomic models, yet why prices are sticky remains a puzzle. We develop a microeconomic model in which two competing firms are free to set prices, but face uncertainty about the state of demand. With some probability, there is a positive demand...

We study the role of whistle-blowing in the following inspection game. Two agents who compete for a valuable prize can either behave legally or illegally. After the competition, a controller investigates the agents' behavior. This control game has a unique equilibrium in mixed strategies. We...

In many markets, homogenous goods and services are sold both by large global frms and small local frms. Surprisingly, the large frms charge, often substantially, higher prices. Examples include hotels, airlines, and coffee shops. This paper provides a parsimonious model that can account for...

Mechanisms where sellers set the price and are charged a linear commission fee are widely used by real world intermediaries, e.g. by real estate brokers. Empirically these commission fees exhibit very little variance, both across heterogeneous regional markets and over time. So far, there is no...

We consider general asset market environments in which agents with quasilinear payoffs are endowed with objects and have demands for other agents' objects. We show that if all agents have a maximum demand of one object and are endowed with at most one object, the VCG transfer of each agent is...

Mechanisms where intermediaries charge a commission fee and have the sellers set the price are widely used in practice e.g. by real estate agents, stock brokers, art galleries, or auction houses. We model competition between intermediaries in a dynamic random matching model, where in every...
