Individual moral hazard engendered by health insurance and monopolistic production are both typical phenomena of drug markets. We develop a simple model containing these two elements and evaluate the market equilibrium on the basis of consumer and social welfare. The consumer welfare criterion...

An all-units discount is a price reduction applied to all units purchased if the customer's total purchases equal or exceed a given quantity threshold. Since the discount is paid on all units rather than marginal units, the tariff is discontinuous and exhibits a negative marginal price...

This paper studies a contracting problem where agents' cost of actions is private information. With two actions, this leads to a two-dimensional screening problem with moral hazard. There is a natural one-dimensional ordering of types when there is both adverse selection and moral hazard....

We analyze the effects of lower bounds on wages, e.g., minimum wages or liability limits, on job design within firms. In our model, two tasks contribute to non-veriable firm value and affect an imperfect performance measure. The tasks can be assigned to either one or two agents. In the absence...

The paper shows that an IMF-like coinsurance arrangement among countries can play a useful role in the global financial system. The operation of the coinsurance arrangement is examined under different loan contracts. It shows that, if the IMF?s objective is to safeguard its resources and be...

The effects of public policy programs which aim at internalizing spill-overs due to successful innovation are analyzed in a sequential double-sided moral hazard doublesided adverse selection framework. The central focus lies in analyzing their impact on contract design. We show that in our...

We analyse a 2-period competitive insurance market which is characterized by the simultaneous presence of standard moral hazard and adverse selection with regard to consumer time preferences. It is shown that there exists an equilibrium in which patient consumers use high effort and buy a...

This paper analyses the relation between authority and incentives. It extends the standard principal / agent model by a project selection stage in which the principal can either delegate the choice of project to the agent or keep the authority. The agent's subsequent choice of e ort depends both...

We derive the shape of optimal unemployment insurance (UI) contracts when agents can exert search effort but face different search costs and have private information about their type. We derive a recursive solution of our dynamic adverse selection problem with repeated moral hazard. Conditions...

This paper contributes to the debate on the efficacy of IMF's catalytic finance in preventing financial crises. Extending Morris and Shin (2006), we consider that the IMF's intervention policy usually exerts a signaling effect on private creditors and that several interventions in sequence may...
