This paper summarises a decade of research by the authors into the welfare economic foundations for agricultural policy. The main results are that the levels of support to agriculture in rich developed countries like Norway are way out of proportion with what could conceivably be defended by...

The paper reviews the theory of environmental taxation under first best and second best conditions. It argues that negative environmental externalities lead to reductions of the provision of public goods, while investment in abatement increases the supply of public goods. Together with optimal...

Christmas is when people are expected to act selflessly for the well-being of others, but are people actually more altruistic at this time of the year? Responding to this question poses a challenge because of the confounding factors of charitable tax breaks, reciprocity motives, direct social...

This paper develops a model for analysing problems related to centralisation and decentralisation. The model is of the new economic geography type, in which there are agglomeration gains in cities but not in rural areas. These gains are counteracted by residential preferences. We show that, even...

This paper studies the conditions for a welfare-maximizing allocation of resources to the production of global public goods, such as biodiversity, the global climate, the cultural heritage, knowledge, and world peace. A global social welfare function is maximized subject to production...

We are concerned with economic analyses of markets from the perspective of supporting a decision maker selling in the market. The competitive pressure and the price formation are central issues. The goal of this paper is to highlight the remarkably different price patterns obtained from...

We study the effects of quality regulation on market outcomes by exploiting the staggered phase-in of bioequivalence requirements for generic drugs in Chile. We estimate that the number of drugs in the market decreased by 25%, average paid prices increased by 10%, and total sales decreased by...

Individual retailers may choose to invest in a substitute to a dominant supplier’s products (inside option) as a way of improving its position towards the supplier. Given that a large retailer has stronger investment incentives than a smaller rival, the large retailer may obtain a selective...

Patient mobility is a key issue in the EU who recently passed a new law on patients' right to EU-wide provider choice. In this paper we use a Hotelling model with two regions that differ in technology to study the impact of patient mobility on health care quality, health care financing and...

We study the incentives for hospitals to provide quality and expend cost-reducing effort when their budgets are soft, i.e., the payer may cover deficits or confiscate surpluses. The basic set up is a Hotelling model with two hospitals that differ in location and face demand uncertainty, where...
