The one site self-interacting fermionic model is considered in the presence of an external magnetic field precessing with constant angular velocity around a fixed axis. We get the exact density operator for the identical particle system as well as its one-particle properties, for general initial...

The topics discussed in the Handbook on the Economics of Natural Resources are essential for those looking to understand how best to use and conserve the resources that form the foundation for human well-being. These include nonrenewable resources, modeling of biological resources, conservation...

This paper examines a dynamic game of exploitation of a common pool of some renewable asset by agents that sell the result of their exploitation on an oligopolistic market. A Markov Perfect Nash Equilibrium of the game is used to analyze the effects of a merger of a subset of the agents. We...

We consider a renewable resource being exploited in common by firms that compete both in the output market and in the exploitation of the resource. We show that the introduction of the slightest cost differentiation among the firms can have a drastic effect on the nature of the equilibria that...

We take a capital asset pricing approach to the determination of the price of a nonrenewable natural resource in the case where the resource is durable, in the sense that once extracted it becomes a productive asset held above ground. The portfolio choice is then made up of the following assets:...

A partial equilibrium analysis shows that a pool of natural resources with constant unit costs of extraction has to be exploited in strict increasing cost order. Kemp and Long [1980] have shown that it is not necessarily the case in a general equilibrium framework. In a consumption-leisure...

We study the optimal valuation of semi-renewable resources, like groundwater, under different assumptions as to the evolution of the population. When the population is either constant or decreasing, valuations of flow and stock resources are identical. With an increasing population however, an...

We analyze the exploitation of an antibiotic in a market subject to open access on the part of antibiotic producers to the common pool of antibiotic efficacy. While the market equilibrium depends only on current levels of antibiotic efficacy and infection of the epidemiological system, the...

Natural resource stocks held in situ are physical assets. Equilibrium in the assets market requires that their rates of return be such that their owners are just willing to hold on to them rather than invest elsewhere. I discuss a number of factors relating to the evolution of extraction costs,...
