While models of mixed oligopoly have been analyzed within a rapidly growing literature, little is known about the mechanism of efficiency improvement relating to partial privatization. In this paper, we endogenize efficiency improvement in relation to the level of privatization. We show that in...

A motivation for the paper is to reveal the "calculative silences" of scholars who limit their research and teaching to organisations that are centralised command and control hierarchies favoured by dictators. Centralisation introduces systemic unethical and dysfunctional relationships from the...

Due to recent legislation, Benchmarking in the German water and sewerage sector will be introduced as widely as possible. Under certain conditions this decision by the German Bundestag might help to improve the efficiency of the industry. I will define two sets of conditions. First, a useful...

There is a lack of competition in the German water and sewerage sector. According to economic theory levels of service can be expected to be inefficient. I will check this hypothesis and therefore take a closer look at various categories of levels of service. In analysing the internet pages of...

The question non longer is if more competition should be introduced in the German water and sewerage sector. The issue rather is what kind of competition ought to be implemented. There are mainly three different approaches: Competition in the Market; Competition for the Market and the...

Spanish Abstract: El documento presenta una revisión de la literatura sobre empresas públicas y regulación, con el objetivo de establecer las características fundamentales que debería contener esta última para atender a las particularidades de dichas empresas. Identificar las diferencias...

The aim of this paper is to investigate the welfare effect of privatization in oligopoly when the government takes into account the distortionary effect of raising funds by taxation (shadow cost of public funds). We analyze the impact of the change in ownership not only on the objective function...

I study the endogenous choice of a price or quantity contract in a mixed duopoly with a socially concerned firm which maximizes a combination of profit and consumer welfare. Contrasting the literature, I find that equilibria where firms adopt price contracts and quantity contracts might coexist....

The purpose of this paper is to investigate the effect of privatization in a mixed duopoly, where a private firm complete in quantities with a welfare-maximizing public firm. We consider two inefficiencies of the public sector : a possible cost inefficiency and an allocative inefficiency due to...
