The single crossing assumption simplifies the analysis of screening models as local incentive compatibility becomes sufficient for global incentive compatibility. If single crossing is violated, global incentive compatibility constraints have to be taken into account. This paper studies monotone...

This paper analyzes the impact of labor market competition and skill-biased technical change on the structure of compensation. The model combines multitasking and screening, embedded into a Hotelling-like framework. Competition for the most talented workers leads to an escalating reliance on...

We analyze competitive credit markets with asymmetric information in which borrowers seek financing for either positive or negative net present value projects. The striking result is that there always exists an equilibrium where investment is efficient, while competitive lenders make strictly...

This paper studies general markets with adverse selection in which symmetric firms supply (potentially multiple) products to privately-informed consumers and compete with price schedules. I show that a basic price cap regulation, in which the price caps are endogenously determined by firms,...

We develop a dynamic model of debt contracts with adverse selection and belief updates. In the model, entrepreneurs borrow investment goods from lenders to run businesses whose returns depend on entrepreneurial productivity and common productivity. Entrepreneurial productivity is the...

We show that a necessary and sufficient condition for entry to be unprofitable in markets with adverse selection is that that no buyer type be willing to trade at a price above the expected unit cost of serving those types who are weakly more eager to trade than her. We provide two applications...

I study the optimal incentive provision in a principal–agent relationship with costly information acquisition by the agent. I emphasize that adverse selection or moral hazard is the principal's endogenous choice by inducing or deterring information acquisition. The principal designs the...

This paper studies general health insurance markets. It proposes an ex post risk adjustment scheme that discourages risk selection and promotes efficient competition. Under the proposed risk adjustment scheme, the regulator engages in transfers that are conditional on the ex post profits of...

This paper studies the effects of redistributive taxation in credit markets with adverse selection and shows that there exists a range of taxes that creates Pareto improvement relative to the (zero-tax) market allocation by increasing aggregate investment. For sufficiently high taxes, an...

We study transactions in which sellers fears being underpaid because their outside option is better known to the buyer. We rationalize various observed contracts as solutions to such smart buyer problems. Key to these solutions is granting the seller upside participation. In contrast, the lemons...
