We study an international climate agreement that assigns emission quotas to each participating country. Unlike the simplest models in the literature, we assume that abatement costs are affected by R&D activities undertaken in all firms in all countries, i.e. abatement technologies are...

We consider an economy where most of the health care is publicly provided,and where there is waiting time for several types of treatments. Privatehealth care without waiting time is an option for the patients in the publichealth queue. We show that although patients with low waiting costs...

A standard result in the literature on environmental economics is that efficient environmental policies regulating transboundary pollution will be adopted only if there is interjurisdictional coordination. Efficient policies can be adopted as a result of interregional treaties or mandated by a...

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...

It is widely recognized that a cost-efficient way to achieve the climate targets of the Paris agreement requires investment in carbon capture and storage (CCS). However, to trigger sizeable investment in CCS the carbon price must exceed the historic carbon prices. This paper examines whether a...

To reach the goals of the Paris agreement, net carbon emissions must be reduced to zero by the second half of this century. To achieve this, some kind of carbon dioxide removal (CDR) is needed. The paper gives an analysis of the interaction between extraction of fossil energy resources and CDR....

In countries where health care is publicly provided and where equity considerations play an important role in policy decisions, it is often argued that an increase in co-payments is unacceptable as it will be particularly harmful to the less well-off in society. The present paper derives...

Fossil fuels are non-renewable carbon resources, and the extraction path of these resources depends both on present and future demand. When this Hotelling feature is taken into consideration, the whole price path of carbon fuel will shift downwards as a response to the reduced cost of the...

If investors fear that future carbon taxes will be lower than currently announced by policy makers, long-run investments in greenhouse gas mitigation may be smaller than desirable. On the other hand, owners of a non-renewable carbon resource that underestimate future carbon taxes will postpone...
