This paper studies optimal investment in different types of electric plants. Neither future fuel prices nor future demand are known. Furthermore, we take into account explicitly the problems of management of the peak load and of the decrease of efficiency of plants used for long periods. A two...

An elementary proof of the existence of a competitive equilibrium is given for economies where the weak axiom of revealed preference or the gross substitution property hold. It is shown by an induction argument that in these cases, the problem is reduced to the question of the existence of an...

In this paper we analyse the problem of the modelling of individual transitions in presence of an incomplete sampling scheme.

We examine an important class of decision problem under uncertainty that entails the standarrd portfolio problem and the demand for coinsurance. The agent faces a controllable risk -his demand for a risky asset for example- and a background risk. We determine how a change in the distribution in...

This paper extends the theory of irreversible investment under uncertainty to incorporate capacity constraints and uncertainty on the input price. In addition, no restriction on the demand elasticity value is imposed. Assuming input price follows a geometric Brownian motion, the optimal...

Organizations require discretionary decision making to be delegated and to be under only partial scrutiny from supervisors. This introduces the possibility for agents to use their discretionary power to their own advantage and in detriment to the organization. We model this situation by...

Consider a general equilibrium framework where the marginal cost of extraction from several deposits of an exhaustible resource is constant in terms of an inexhaustible perfect substitiute and differs between deposits. The instantaneous rate of productionfrom the inexhaustible resourcce is...
