This paper studies the role of exchange policies as a price discrimination device in a sequential screening model with heterogeneous goods. In the first period, agents are uncertain about their ordinal preferences over a set of horizontally differentiated goods, but have private information...

We develop a model of credit rating agencies (CRAs) based on reputation concerns. Ratings a ffect investors' choice and, thereby, also issuers' access to funding and default risk. We show that in equilibrium - the informational content of credit ratings is inferior to that of CRAs' private...

We study a health-insurance market where individuals are o.ered coverage against both medical expenditures and losses in income. Individuals vary in their level of innate ability. If there is private information about the probability of illness and an individual’s innate ability is su.ciently...

We consider how a benevolent regulator should regulate a polluting export industry when the industry, having private information about its abatement efficiency, has an option to move its operations abroad, with a type-dependent outside option rent. The paper focuses on the case where outside...

We discuss the prevalence of pooling equilibria in a two-period model of an insurance market with asymmetric information. We solve the model numerically. In addition to reporting cases where a pooling equilibrium exists, we pay attention to why, in the case of non-existence of a pooling...

Genetic insurance can deal with the negative effects of genetic testing on insurance coverage and income distribution when the insurer has access to information about test status. Hence, efficient testing is promoted. When information about prevention and test status is private, two types of...

A central theme in the international debate on genetic testing concerns the extent to which insurance companies should be allowed to use genetic information in their design of insurance contracts. We analyze this issue within a model with the following important feature: A person’s well-being...

We analyse environmental policy under asymmetric information in a context where a homepolluting firm, selling its final output solely in a foreign market with some market power, has an option to bypass domestic regulation through setting up new plants in a jurisdiction offering lenient...

Regulating an export firm (or a homogeneous industry) with private information about emission technology is analysed, when the firm, owned partly by foreigners, has an option to bypass domestic regulation through costly relocation. If the firm chooses to relocate, it will set up a new plant in a...

An entrepreneur with information about firm quality seeks financing from an uninformed investor in order to pay a worker. I show that if the worker, too, knows the true quality of the firm, then certain long term wage agreements can credibly signal firm quality. Such wage agreements have a low...
