After Wicksell in 1911 had published the second Swedish edition of his Lectures on Political Economy, a debate began in the Ekonomisk Tidskrift between Wicksell and his opponent Sven Brisman. The controversy was mainly about the concept of capital and the rate of interest, but the circumstances...

In this article we propose a model in which individuals experience habit formation in environmental quality. Further, a consumption good causes a negative external effect on the environment.The intertemporal utility of a benevolent social planner depends on consumption of two goods and the...

We model self-control conflict as a stochastic struggle of an agent against a visceral influence, which impels the agent to act sub-optimally. The agent holds costly pre-commitment technology to avoid the conflict altogether and may decide whether to procure pre-commitment or to confront the...

We analyze optimal social discount rates when people derive utility from relative consumption. We compare the social, private, and conventional Ramsey rates. Assuming a positive growth rate, we find that 1) the social discount rate exceeds the private discount rate if the importance of relative...

We study how gender, birth-order and number of siblings are related to stated time and risk preferences and real-life decisions. We use survey data covering about 2,300 individuals and find that time and risk preferences are significantly correlated among women but not among men. We also find...

This paper combines knowledge from soil science and economics to estimate economic determinants of soil capital. Explaining soil capital facilitates a better understanding of constraints and opportunities for increased agricultural production and reduced land degradation. The study builds on an...

We show that peer sanctioning increases cooperation in public goods experiments more in unequally endowed groups than in equally endowed groups. Punishment results in a redistribution of wealth from high to low endowment players within groups. <p>

This report reviews the current status of second generation biofuels. First generation biofuels continue to be substantially subsidized, and this has contributed to the increasing use of such fuel. However, recent studies claim that the future of biofuels lies in second generation biofuels, in...

This paper provides the latest research developments in the method of choice experiments applied to valuation of non-market goods. Choice experiments, along with the, by now, well-known contingent valuation method, are very important tools for valuing non-market goods and the results are used in...

Soil erosion and fertilizer run-off cause serious flow externalities in downstream environments through-out the world. Social costs include e.g. loss of health, life and production due to pollution and eutrophication of freshwater resources, reduced life of hydro-power plants, increased...
