This paper estimates a translog cost function for Swiss water utilities. From the cost function, we are able to estimate measures of marginal costs as well as economies of production density, customer density and scale, which are important determinants in water policies, such as planning and...

In this paper, we assess the economic efficiency of Swiss water utilities. To reach this aim, we accessed a new and unexploited database, which counts 330 water utilities, representing about 55% of the drinking water distributed in Switzerland. The database spans over six years (2000-2005) and...

We study the strategic utilization of storage in imperfect electricity markets. We apply a game-theoretic Cournot model to the German power market and analyze different counterfactual and realistic cases of pumped hydro storage. Our main finding is that both storage utilization and...
