The aim of this paper is to present an alternative methodology for discounting far distant future externalities genereted by an investment project: time-declining discount rates. First I present the experimental evidence on individuals' time-inconsistency. Second I consider the theoretical...

In the paper we propose an to evaluation of the environmental effects of consumption activities. The approach consists of two steps, namely (1) assignment of environmental effects to consumption activities, for which we propose to use the methods of (multidimensional) cost sharing, and (2) a...

This paper investigates the effect of credibility of environmental policies on environmental innovation and welfare. When the government precommits to an emission tax, the monopolist's abatement effort is lower than if the environmental policy is at the government's discretion. Time consistent...

In this paper, distribution and welfare effects of changes in block price systems are evaluated. A method is discussed to determine, for a Marshallian demand function, equivalent variation in case of a block price system. The method is applied to analyze welfare and distribution effects of...

This paper examines a simple North-South growth model where negative externalities may contribute to reinforce economic growth. Agents' welfare depends on three goods in the model: leisure, a common access renewable natural resource (one in each hemisphere) and a non-storable consumption good....

We derive a theoretically consistent welfare measure that is to be interpreted as a "green" net national product (NNP). In our framework, environmental deterioration is modelled as an undesirable, but inherent by-product of economic activities consuming the resource base. A major advantage of...

Adoption of climate change response options generates not only global carbon-saving benefits but also local externalities, here denominated as secondary benefits. So far funding for global warming response options, such as GEF, has discriminated against secondary benefits (SD) in their project...

In this paper, the expansion of private production erodes the quality of commonly owned goods, thereby forcing individuals to rely increasingly on private goods to satisfy their needs. In the face of this deterioration, households keep their labour supplies and saving rates relatively high in...

We evaluate the effectiveness of non optimal and temporally inconsistent incentive policies for regulating the exploitation of a renewable common-pool resource. The corresponding game is an N-person discrete-time deterministic dynamic game of T periods fixed duration. Three policy instruments...

We analyse growth dynamics in an economy where the well-being of economic agents depends on three goods: leisure, a free access environmental good and a private good which can be produced by each agent through his own labour input. The private good can be consumed as a substitute for the...
