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...

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 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...

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...

In many markets homogenous goods are sold both by large global firms ("chain stores") and small local firms. Surprisingly, chain stores often charge higher prices. Examples include hotels, airlines, and coffe shops. We provide a simple model that can account for these pricing patterns. In this...

This paper analyzes price competition between market makers who set costly capacity constraints before they intermediate between producers and consumers. The key finding is that the unique perfect equilibrium outcome is Cournot if capacity is costly and rationing efficient. This result is...

We consider a median voter model with uncertainty about how the economy functions. The distribution of income is exogenously given and the provision of a public good is financed through a proportional tax. Voters and politicians do not know the true production function for the public good, but...

I present a model of competition between two market makers who are horizontally differentiated. I first show that absent a search market for buyers and sellers, there is a continuum of symmetric equilibria. These equilibria are payoff equivalent for market makers, but affect buyers' and sellers'...

We consider Hotelling location games with global and local players. Global players are active in several markets, while local players act in a single market only. The decisive feature is that global players cannot tailor their product to each market but have to choose a location on the Hotelling...
