We propose a new measure of market liquidity based on the investors' optimal searching behaviour. Thus, we add a wealth filter on Pagano (1989)'s measure of liquidity to build the strong tie between endogenous market participation and investor wealth, as has been documented by empirical works.

Research in behaviour finance has provided seemingly persuasive evidences that overconfidence affects asset prices. We provide a model with model uncertainty and overconfidence in which overconfidence could have no effect on asset prices.

We analyse incentive problems in collective production environments where contributors are compensated according to their observed and ranked efforts. This provides incentives to the contributors to choose first best efforts.

This paper analyzes the efficiency of team production when agents exhibit other regarding preferences. It is shown that full efficiency can be sustained as an equilibrium through a budget-balancing mechanism that punishes some randomly chosen agents if output falls short of efficient level but...

We formalize a conception of authority, which is commonly defined as the right of controlling a person's actions embedded in human assets in sociology. Due to the inalienable property of human assets, the contractible formal authority is hard to verify and enforce, while real authority usually...

In Spence's (1973) signaling by education model and in many of its extensions, firms can only infer workers' productivities from their education choices. In reality, firms also use sophisticated pre-employment auditing to learn workers' productivities. We characterize the trade-offs between...

In Spence’s (1973) signaling by education model and in many of its extensions, firms can only infer workers’ productivities from their education choices. In reality, firms also use sophisticated pre–employment auditing to learn workers’ productivities. We characterize the trade–offs...

Die klassische oekonomische Theorie behauptet, dass Teams und Partnerschaften (Teilhaberschaften) vom Trittbrettfahrerproblem betroffen sind und dass kapitalistische Unternehmen besser in der Lage sind, Spieler zu gewuenschten Handlungen zu motivieren. Dies steht jedoch im Widerspruch zur...
