In this paper, we examine the effect of increases in health care costs and general inflation on optimal insurance policies and waste in a model of imperfect information with costly auditing. We show that in such a setting, individuals will buy more than full insurance. Moreover, as the cost of...

How does renegotiation affect contracts between a principal and an agent subject to persistent private information and moral hazard? This paper introduces a concept of renegotiation-proofness, which adapts to stochastic games the concepts of weak renegotiation-proofness and internal consistency...

This paper studies the problem of incentivizing an agent in an innovation project when the progress of innovation is known only to the agent. I assume the success of innovation requires an intermediate breakthrough and a final breakthrough, with only the latter being observed by the principal....

Electronic commerce and flexible manufacturing allow personalization of initially standardized products at low cost. Will customers provide the information necessary for personalization? Assuming that a consumer can control the amount of information revealed, we analyze how his decision...

In this paper a modified version of Bernanke and Blinder�s (1988) model of the bank lending channel of monetary policy under asymmetric information is presented. If, aside from reserve requirements, banks have to meet capital adequacy requirements as well, then the results suggested by...

Contrary to what is consistently assumed in the literature, the return function cannot be hump-shaped in the Stiglitz-Weiss (1981) model. This has important consequences for the possible occurrence of credit rationing and redlining. With a single class of borrowers, banks offer credit in two...

Certification schemes for forest products are understood by many as a way to promote sustainable resource use when it is impossible to rely on direct enforcement of process standards. Based on the concept of ‘Self-Enforcing Contracts’, this study develops a market model that simulates the...

We consider multistage bidding models where two types of risky assets (shares) are traded between two agents that have different information on the liquidation prices of traded assets. These prices are random integer variables that are determined by the initial chance move according to a...
