We adapt the classical Schaefer model of fisheries management to take into account intergenerational equity, in the line of Sumaila ([18]) and Sumaila and Walters ([19]). The resulting discount rate then is non-constant, and the planner’s preferences are time inconsistent, so that optimal...

We model an economy that alternates randomly between abundance and scarcity episodes. We develop an original method to characterize in detail the structure of the Markovian competitive equilibrium. Accumulation and drainage of stocks are the main focuses. Economically appealing comparative...

Based on evolutionist theories and project management knowledge, a connectionist model based on genetic algorithm is built to simulate innovation process in organizations. Transformation and selection produce micro dynamics to create macro behavior in the agents' population. Results clarify...

It is shown that backward-forward procedure which selects solutions in dynamic models with rational expectations may fail to give a solution when the lags are of order two.

An essential element of any realistic investment portfolio selection is the consideration of transaction costs. Our purpose, in this paper, is to determine the maximum return and the corresponding number of securities to buy giving such return, whenever practical constraints features related to...

In this paper we study BSDEs arising from a special class of backward stochastic partial differential equations (BSPDEs) that is intimately related to utility maximization problems with respect to arbitrary utility functions. After providing existence and uniqueness we discuss the numerical...

In this paper the modelling of venture capital decision making is being attempted, using a multicriteria decision support system (the Minora system) based on the interactive use of the Uta ordinal regression model. First, a review of the literature on the evaluation criteria for venture capital...
