Non-linear income taxes and linear commodity taxes are analysed when people differ with respect to ability, high-skilled agents have heterogeneous preferences, and neither individual abilities nor preferences are observable. The paper highlights how informational constraints may motivate...

This paper investigates the relative magnitude of the components in the bid-ask spread <p> around earnings announcements using the method in Stoll (1989).

The Schumpeterian view on Business cycles treats recessions as a cleansing mechanism and a state where firms can regroup and innovate. Firms need to access finance externally in order to compensate declining cash flow in recessions. Due to financial frictions, the literature proposes that firms...

We develop a simple yet realistic model of income insurance, where the individual’s ability and willingness to work is treated as a continuous variable. In this framework, income insurance not only provides income smoothing, it also relieves the individual from particularly burdensome work. As...

Markets with imperfect competition do not induce a cost-minimizing allocation of production between firms. The market's ability to rationalize production is even more limited if costs are private information to firms. Merger in such markets generate an efficiency gain associated with the pooling...

Bester and Strausz (2000) showed that the revelation principle of Bester and Strausz (2001) does not apply in a setting of many agents and no commitment. In their counterexample only one agent has private information. We show that if the parties can make ex ante transfers the revelation...

A large literature on ex ante moral hazard in income insurance emphasizes that the individual can affect the probability of an income loss by choice of lifestyle and hence, the degree of risk-taking. The much smaller literature on moral hazard ex post mainly analyzes how a “moral hazard...

We develop a simple yet realistic model of income insurance, where the individual’s ability and willingness to work is treated as a continuous variable. In this framework, income insurance not only provides income smoothing, it also relieves the individual from particularly burdensome work. As...

We study the adverse selection problem in imperfectly competitive credit markets and illustrate the circumstances where a separating equilibrium emerges, even without collateral. The borrowers are heterogeneous in their preferences concerning the banks. Separation obtains in market segments...

This paper studies how comparing can be used to provide information in financial markets in the presence of a hidden characteristics problem. Although an investor cannot precisely estimate the future returns of an entrepreneur’s projects, the investor can mitigate the asymmetric information...
