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 use a principal-agent framework to reexamine the implications of the negligence and strict liability rules when the tort-feasor is an agency. We assume a unilateral care situation and consider both the cases of moral hazard and of adverse selection. In both instances the negligence rule is...

This paper provides a dynamic general equilibrium framework to investigate how organizations change the modes to govern transactions over time. We show that the agency problem becomes less serious when the economy is developed well so that large market size favors decentralized organizations...

This paper studies frequent monitoring in a simple infinitely repeated game with imperfect public information and discounting, where players observe the state of a continuous time Brownian process at moments in time of length Δ. It shows that efficient strongly symmetric perfect public...

We study the effect of strengthening CACs in a debt rollover model of a sovereign debt crisis. Conditional on default, there are multiple equilibria: the impact of strengthening CACs depends critically on the prevailing equilibrium. For a subset of equilibria, (i) given a fixed number of...

<span style="font-size:10.0pt; font-family:"Arial","sans-serif"">This paper analyses the welfare effects of microfinance and inflation in developing countries. Therefore, we introduce a moral hazard problem into a monetary search model with money and credit. We show how access to basic financial services affects households' decisions to borrow, to save and to...</span>

Transparency has become a catchword and in the economic-political debate is often seen as a universal remedy for all sorts of problems. In this paper, we analyze and discuss the meaning and use of the concept of transparency in economic research. We look for common denominators across different...

In a public procurement setting, we discuss the desirability of completing contracts with state-contingent clauses providing for monetary compensations to the contractor when revenue shocks occur. Realized shocks are private information of the contractor and this creates agency costs of...
