This paper models joint implementation (JI) for emission reduction between a developed and a developing country. When the per unit price of JI abatement is negotiated, the relative pay-offs deviate from the ratio of bargaining powers. When firms bargain, country-wise gains can increase with a...

The search for sustainability indicators should be guided by a theory of sustainable development (SD). In this paper we investigate two such theoretical frameworks and the indicators that they suggest. Indicators associated with weak sustainability are characterized by aggregative indicators...

To protect the elephant, trade in ivory has been banned since 1990. In this paper, we demonstrate that this ban's effect on elephant populations is ambiguous. Depending on the discount rate, among other things, the trade ban can either increase or decrease optimal population size. If the...

This paper seeks to develop a basic analytical framework that can be used to trace the environmental impacts of macroeconomic policies, and especially to identify where unforeseen negative environmental effects may occur and design remedial measures. The framework is based on a formal...

International transfers to developing countries are sometimes advocated on the ground that they contribute to tropical forest conservation. Here we demonstrate that the effectiveness (and attractiveness) of this instrument is reduced if the restrictive assumption of deterministic prices is...

The paper reviews two alternative rules for allocation of property rights in a global greenhouse-gas emissions budget, assuming implementation of a tradablequota arrangement. These are the per capita rule and no-regrets-for-the-South (NRFTS) rule. The operation of a quota market under these...

The paper analyzes the conflict between illegal and legal exploitation of wildlife species in an East African context. In the model there are two agents, an agency managing a national park of fixed area and a group of local people living in the vicinity of the park. The park agency has the legal...

The paper analyses the conflict between wildlife conservation and its accompanying land-use in an East African context. In the model there are two agents. First, there is an agency managing the wildlife and the habitat of the wildlife, which is referred to as parkland. On the other hand, there...
