The purpose of this paper is to show that in a general equilibrium framework it is never optimal to use high cost substitute after lower cost exhaustible resource even if it is possible to accumulate productive capital. Indeed if the high cost substitute is scarce it is always optimal to consume...

This paper examines the sequence of optimal extraction of nonrenewable resources in the presence of multiple demands. We provide conditions under which extraction of a nonrenewable resource may be discontinuous over the course of its depletion

In this paper, we analyse a control theoretic model of a country possessing a finite amount of a nonrenewable resource. The country can both consume the indigenous resource and export it. Moreover, a substitute for the indigenous resource is available at a given backstop price. We obtain the...

In this paper, we analyze the question of membership in a non-renewable resource cartel, with specific application to OPEC. Using a simple model of a non-renewable resource market, we show that the benefits of cartel membership are related to the size of remaining reserves. Domestic petroleum...

CCS (carbon dioxide capture and storage) is an issue which has received increasing attention in the debate on climate change over the last years because of its relative technical simplicity and a large expected potential in reducing carbon dioxide emissions. The coexistence of both strong...

We consider the Hartwick rule for capital accumulation and resource depletion, provide semantic clarifications and investigate whether this rule indicates sustainability and requires substitutability between manmade and natural capital. In addition to shedding light on the meaning of the...

In this paper, we analyze the question of membership in a non-renewable resource cartel, with specific application to OPEC. One would expect the benefits of cartel membership to be positively related to the size of remaining reserves, while domestic petroleum consumption should be negatively...

The separation of powers and responsibilities has evolved over time in Italy given that political ideals have been pushing towards a greater decentralization for the last twenty years. Under environmental federalism issues, an interesting case of study - capable of being empirically treated - is...

If environmental quality positively affects the productivity of labor in R&D and pollution is caused by the use of a non-renewable resource, it is socially optimal to postpone extraction and to intertemporally adjust R&D effort.
