This paper examines the effect of risk-aversion on the short-run supply of timber, when the harvest revenue can be invested in a risk-free and a risky asset. It turns out that recognition of the risky investment alternative invalidates the previously reported effect of risk-aversion on short-run...

Previous studies have reported significant gains from adaptive harvest strategies when future timber prices are uncertain. For the final harvest decision in even-aged stand management, the adaptive strategy typically means that a stand is harvested only when the timber price is high, whereas low...

In this paper, we model the economic incentives surrounding opium crop production at farm level in Afghanistan. Specifically, we examine the impact of eradication policies when opium is used as a means of obtaining credit, and when the crops are produced in sharecropping arrangements. The...

This thesis consists of a summary and four self-contained papers. Paper [I] examines whether the implementation of a social safety net programme in Ethiopia has affected the value, risk and composition of farmers’ crop portfolios. The empirical analysis suggests that the value and risk of the...

The starting point for this paper is the potential self-control problem underlying the consumption of unhealthy food. The purpose is to analyze public policies, which are designed to correct for the welfare loss associated with such behavior. Contrary to previous studies, our analysis suggests...

This paper concerns income taxation, commodity taxation, production taxation and public good provision in a multi-jurisdiction framework with transboundary environmental damage. We assume that each jurisdiction is large in the sense that its government is able to influence the world-market...

This paper concerns international coordination of environmental taxation. The main purpose is to study the global welfare effects that will arise, if there is an agreement between countries to slightly increase their emission taxes. We show that even if each individual country has chosen its...

Earlier literature on tax competition and policy coordination typically assumes that the labor market is competitive; a description less suitable for Europe, where trade unions have had a strong position in the labor market for a long time. This paper concerns factor income taxation and public...
