Using a Verreccia [1983]-type model, we study the optimal voluntary disclosure strategy of a manager with private information that helps the market interpret financial information the firm is required to report. In equilibrium, the manager’s disclosure strategy enhances upward or mitigates...

This paper studies whether there exists private information in the foreign exchange market, and whether speculation reduces or exacerbates volatility. It makes use of a recent data set on foreign currency positions by large market participants that include positions on options and other...

Introducing assets backed by physical collateral, we extend the Cornet and De Boisdeffre (2002) model of asymmetric information to allow for default. We show that, independently of the financial-informational structure, equilibrium exists.

Given wide scope for asymmetric information in huge hierarchies agents have a large capacity for opportunistic behaviour. Hidden actions increase transactions costs and cause the demand for monitoring and enforcement. Once the latter are costly, this raises questions about their scope, logistics...

This paper offers a contract-based theory to explain the determination of standard hours, overtime hours and overtime premium pay. We expand on the wage contract literature that emphasises the role of firm-specific human capital and that explores problems of contract efficiency in the face of...

The paper analyzes the financial crisis of the late 1990s in East Asia by trying to explain the predominant role played by the credit institutions in the intermediation process and in the creation of endogenous financial fragility and instability at a system level. This view is in contrast with...

From David Ricardo making a fortune buying British government bonds on the eve of the Battle of Waterloo to Warren Buffett selling insurance to the California earthquake authority, the wisest investors have earned extraordinary returns by investing in the unknown and the unknowable (UU). But...

This study presents a model of optimal contracting for health services in the presence of excess demand and waiting times. We assume that: i) hospitals differ in their demand for treatment; ii) potential demand is private information of the provider; iii) specialists can dump patients; iv)...

Nearly all observational learning models assume that individuals can observe all the decisions that have previously been made. In reality, such perfect information is rarely available. To explore the difference between observational learning under perfect and imperfect information, this paper...
