We study how measures of socioeconomic health inequality inform about welfare inequality. We argue that transfers of either income or health from a better off to a worse off individual should reduce welfare inequality. Lacking an objective measure of individual welfare, we suggest that such a...

We present a simple approach to transform a deterministic numerical model, where several agents simultaneously make decisions, into a stochastic model. This approach, which builds on scenario aggregation, a numerical method developed to solve decision problems under uncertainty, is used to build...

In public good games, voluntary contributions tend to start off high and decline as the game is repeated. If high contributors are matched, however, contributions tend to stay high. We propose a formalization predicting that high contributors will self-select into groups committed to charitable...

This paper focuses on two equity dimensions of climate policy, intra- and intergenerational equity, and analyzes the implications of equity preferences on climate policy, and on the production and consumption patterns in rich and poor countries. We develop a dynamic two-region model, in which...

We study the interactions between fuel efficiency improvements in the transport sector and the oil market, where the efficiency improvements are policy-induced in certain regions of the world. We are especially interested in feedback mechanisms of fuel efficiency such as the rebound effect,...

Most studies show that the present generation has to take the burden and reduce consumption to mitigate future climate change. However, significant climate change is due to a market failure, and corrections of market failures give possibilities of Pareto improvements. In this paper, we study the...

The Coordination Reform was introduced in Norway in 2012 including a fee for bed-blocking in hospitals. To study this, we introduce a Stackelberg game where the hospital is the leader and the care institution is the follower. The reform does not necessarily lead to less bed-blocking as this...

Empirical studies show that years of schooling are positively correlated with good health. The implication may go from education to health, from health to education, or from factors that influence both variables. We formalize a model that determines an individual's demand for knowledge and...

We investigate how moral considerations, background conditions and risk can trigger resistance to implement trading institutions. We provide survey results on moral opposition to trade on several goods and services like body organs, sex services, surrogate mothers, trade with developing nations,...

Aiming to reduce the number of brown (polluting) cars on the road, several countries currently promote the purchase and use of green (emission-free) cars through financial and non-financial incentives. We study how such incentives affect consumers who continue to drive brown cars. Using a simple...
