In this paper we consider the optimal impulse control of a system which evolves randomly in accordance with a homogeneous diffusion process in R^1: Whenever the system is controlled a cost is incurred which has a fixed component and a component which increases with the magnitude of the control...

The purpose of this study is to analyze the cost efficiency of electricity distribution systems in order to enable regulatory authorities to establish price- or revenue cap regulation regimes. The increasing use of efficiency analysis in the last decades has raised serious concerns among...

Earlier studies found little evidence of scale economies at large banks; later studies using data from the 1990s uncovered such evidence, providing a rationale for very large banks seen worldwide. Using more recent data, we estimate scale economies using two production models. The standard...

The abatement of non-CO2 greenhouse gases (OGHG) has proved to be of paramount importance for reaching global mitigation targets. The modeling of their abatement is normally carried out referring to marginal abatement cost (MAC) curves, which by now represent a standard approach for such an...
