There is a large literature on the optimal order of exploitation of natural resources. We explore the impact of specific technical progress that enables the saving of resource inputs in production on the order of exploitation. Models of growth tend to assume uniform and global technical progess....

We study the optimal policies of research and development in the context of a resource-exploiting economy. We distinguish two cases: non-renewable resources and renewable resources. In the first case, we show that it is useful to construct an index of scarcity, which is the product of the level...

There exist specific factor scarcities if, and only if, the inputs of the production process are not perfect substitutes. Under the extreme assumption of strict factor complementarity between labour and resources in the production of some aggregate consumption good, and assuming that the...

This paper studies the intertemporal substitutions between the use of renewable and non renewable resources if the productivities of the different kinds of resources are improved through time by exogenous trends of dedicated technical progress. We show that the optimal exploitation paths of the...

Il existe une littérature assez abondante sur l'ordre dans lequel une société devrait utiliser ses ressources au cours du temps. Ce que nous voudrions explorer c'est l'incidence d'un progrès technique spécifique, permettant d'économiser les quantités de ressources requises par unité de...
