In signaling environments ranging from consumption to education, high quality senders often shun the standard signals that should separate them from lower quality senders. We find that allowing for additional, noisy information on sender quality permits equilibria where medium types signal to...

We construct a framework for modeling dynamic Cournot oligopoly. We consider models where utility maximizing consumers give rise to demand functions that depend on current and prior period prices. Future demand depends on the current price and consumers and firms must take this into account when...

I examine a Knightian (1921) model of risk using a general equilibrium model of investment and trade. A population of agents with various preference types can choose between a safe production technology and a risky production technology. In addition, the distribution of types of agents changes...

Although the General Agreement on Trade and Tariffs prohibits discriminatory import tariffs, GATT rules include means by which this prohibition can be circumvented. The previous literature use static models to show that discriminatory tariffs increase welfare. In a dynamic model, this is not...

We propose a simple model of wage dispersion arising from oligopsonistic competition in the labor market. Our model has workers who are equally able but who have heterogeneous preferences for non-wage characteristics, while employers have heterogeneous productivity characteristics. We completely...

When can you cheat some people without damaging your reputation among others? In a trust game between a firm and a series of individuals from two groups of different sizes, the firm has more incentive to cheat minority individuals because trade with the minority is less frequent and the...

The standard resource extraction framework assumes infinitely lived agents and yields an overfishing result. For some applications, a finite time horizon may be more appropriate. A direct extension of the Levhari-Mirman model to overlapping generations yields an extreme overfishing result....

In signalling environments ranging from consumption to education, high-quality senders often shun the standard signals that should separate them from lower-quality senders. We find that allowing for additional, noisy information on sender quality permits equilibria where medium types signal to...
