This paper points to the important role which the elasticity of aggregate capital supply with respect to the net rate of return to capital plays for the efficiency of policymaking in a decentralized economy with mobile capital and spillovers among jurisdictions. In accordance with previous...

I study climate policy choices for a “policy bloc” of fuel-importers, when a “fringe” of other fuel importers have no climate policy, fuel exporters consume no fossil fuels, and importers produce no such fuels. The policy bloc and exporter blocs act strategically in fossil fuel markets....

Using a calibrated overlapping generations model we quantify the welfare gains of an age dependent income tax. Agents face uncertainty regarding future abilities and can by saving transfer consumption across periods. The welfare gain of switching from an age-independent to an age-dependent...

In the standard setting a system of tradable permits is effective and cost-efficient in attaining the policy objective of pollution reduction. This outcome is challenged in case of a tradable permit system in a federal system/constitution with individual states having discretionary power...

Scientific expertise suggests that mitigating extreme world-wide climate change damages requires avoiding increases in the world mean temperature exceeding 2◦ Celsius. To achieve the two degree target, the cumulated global emissions must not exceed some limit, the so-called global carbon...

The green paradox conveys the idea that climate policies may have unintended side effects when taking into account the reaction of fossil fuel suppliers. In particular, carbon taxes that will be implemented in the future induce resource owners to extract more rapidly which increases present...

Much of the theoretical literature on inequality assumes that the equalisand is a cardinal variable like income or wealth. However, health status is generally measured as a categorical variable expressing a qualitative order. Traditional solutions involve reclassifying the variable by means of...

In economic models, risk and social preferences are major determinants of criminal behavior. In criminology, low self-control is considered a fundamental cause of crime. Relating the arguments from both disciplines, this paper studies the relationship between self-control and both risk and...

We study a dynamic model with two competing durable goods; one dirty, the other clean. Due to network effects a consumer who adopts the dirty good today will increase the incentive future consumers have to adopt the dirty good. Thus, a consumer who chooses the dirty good, in a sense causes more...
