In this paper, we consider an asymmetric polluting oligopoly: firms have different production costs, and their pollution characteristics may also be different. We will demonstrate that, in this case, optimal tax rates per unit of emission are not the same for all firms. We call this property...

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 evaluate biodiversity in a real options framework, when the resources in use are substitutable. We examine optimal conservation decisions given that a biodiversity loss is irreversible and that future use values are uncertain. While species substitutability is generally believed to reduce the...

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...

This paper presents a simple model of resource extraction where preferences are household's preferences depend on relative consumption levels. We identify two dimensions along which consumption externalities distort the efficient extraction of resources: (i) the static trade-off between...

We show that when polluting firms are Cournot oligopolists, they may have an incentive to use the market of pollution permits as a means of indirectly coordinating their outputs. If firms are initially identical, trade in pollution permits may result in an asymmetric oligopoly. The case where...

We characterize optimal firm-specific emission tax rates, and optimal firm-specific emission standards, and provide intuitive explanation on differential treatments. We show that there is a unified framework for deriving firm-specific policy measures. When firms are identical, the optimal policy...

This paper distinguishes relative risk aversion and resistance to intertemporal substitution in climate risk modeling. Stochastic recursive preferences are introduced in a stylized numeric climate-economy model using preliminary IPCC 1998 scenarios. It shows that higher risk aversion increases...
