Eleven percent of the Malawian population is HIV infected. Eighteen percent of sexual encounters are casual. A condom is used one quarter of the time. A choice-theoretic general equilibrium search model is constructed to analyze the Malawian epidemic. In the developed framework, people select...

This paper introduces a virtually efficient mechanism in a setting with sequentially arriving agents who hold informative signals about future types. To reveal the information the principal organises betting on future type reports. An agent´s betting reward depends on how accurately the prior...

This paper analyzes the case of a principal who wants to provide an agent with proper incentives to explore a hypothesis that can be either true or false. The agent can shirk, thus never proving the hypothesis, or he can avail himself of a known technology to produce fake successes. This latter...

We study firms' incentives to acquire costly information in booms and recessions to understand the role of endogenous information in explaining asymmetric business cycles. When the economy has been in a boom in the previous period, and firms enter the current period with an optimistic belief,...

The paper proposes a continuous time model of an FX market organized as a multiple dealership. The model reflects a number of salient features of the Czech koruna spot market. The dealers have costly access to the best available quotes. They interpret signals from the joint dealer-customer order...

A player of privately known strength chooses when to enter a market, and an incumbent chooses whether to compete or concede. Information about the potential entrant's type is revealed publicly according to an exogenous news process and the timing of entry. I analyze stationary equilibria using...

This paper introduces a virtually efficient mechanism in a setting with sequentially arriving agents who hold informative signals about future types. To reveal the information the principal organises betting on future type reports. An agent’s betting reward depends on how accurately the prior...

We develop a framework in which: (i) a firm can have a new product tested publicly before launch; and (ii) tests vary in toughness, holding expertise fixed. Price flexibility boosts the positive impact on consumer beliefs of passing a tough test and mitigates the negative impact of failing a...

We study how asymmetric information impinge on oligopolistic firms’ decision between direct investment and exports in a game-theoretic model with Bayesian learning. Host firms have superior information about market demand and foreign firms can improve their knowledge if foreign direct...

A principal who knows her type can face public testing to help attract endorsements from agents. Tests are pass/fail and have an innate toughness (bias) corresponding to a trade-off between the higher probability of passing a softer test and the greater impact on agents’ beliefs from passing a...
