L'objectif de ce papier est de construire un modele d'evaluation des investissements optimaux a realiser dans les centrales electriques thermiques qui opereront en 2005 en Allemagne. Un autre but de ce papier est d'evaluer, sous l'angle economique, les arguments qui ont pu ou peuvent pousser...

Unemployment rates vary widely at the sub-regional level. We seek to explain why such variation occurs, using data for 174 districts in the Midi-Pyrenees region of France for 1990-91. A set of explanatory variables is derived from theory and the voluminous literature.

The infinite source Poisson model is a fluid queue approximation of network data transmission that assumes that sources begin constant rate transmissions of data at Poisson time points for random lengths of time. This model has been a popular one as analysts attempt to provide explantations for...

We propose a simple model of competition for the production of energy between a thermal station and an hydrostation. We show analytically and geometrically that, despite its static characteristics, the output from the thermal station is determined by the intertemporal specifications of costs and...
