Environmental and tax policies and the optimal provision of clean and dirty public goods are analysed within the context of a second-best framework of optimal taxation. Households consume both clean and dirty commodities. Degradation of the natural environment occurs due to the consumption of...

In this paper we develop techniques for measuring the trade policy equivalent of domestic distortions, using a distance function approach. Our measure, the Trade Restrictiveness Index, is shown to equal the uniform tariff which is welfare-equivalent to a given pattern of domestic taxes and...

The implications of more environmental concern for the optimal provision of public goods, taxation, environmental policy and involuntary unemployment are derived within a second-best framework in which lump-sum taxes and subsidies are not available and labour supply is rationed due to a rigid...

This Paper presents a formal theory of reciprocity. Reciprocity means that people reward kind actions and punish unkind ones. The theory takes into account that people evaluate the kindness of an action not only by its consequences but also by the intention underlying this action. The theory...

In this Paper we show that a simple model of fairness preferences explains major experimental regularities of common pool resource (CPR) experiments. The evidence indicates that in standard CPR games without communication and without sanctioning possibilities inefficient excess appropriation is...

This paper brings the aid effectiveness debate to the sub-national level. We hypothesize the non-robust results regarding the effects of aid on development in the previous literature to arise due to the effects of aid being insufficiently large to measurably affect aggregate outcomes. Using...

Many countries have failed to use natural resource wealth to promote growth and development. They have been damaged by volatility of revenues, have failed to save a sufficiently high proportion of their resource revenues and failed to make high return investments to support diversification of...

In this Paper we focus on the question: Will the HIPC debt reduction program help in the transformation of the development assistance business and change the rules of the ‘debt game’ in Africa? We concentrate on the donor and official creditor side, by exploring how the growing debt of...

This Paper discusses the challenges confronting developing countries seeking to overcome discrimination in world trade rules and policies. The major sources of discrimination in both developed and developing countries in the areas of market access opportunities and WTO disciplines are briefly...

We develop a political-economic model of aid fungibility. A donor country gives aid to a recipient government for the benefit of a target group. However, the recipient government accepts political contributions from a lobby group not targeted by the donor and transfers a fraction of the aid to...
