Ein Jahr nach Inkrafttreten der deutschen Energierechtsnovelle sind die Konturen der zukünftigen Strommarktregulierung noch zu weiten Teilen ungeklärt. Vor diesem aktuellen wirtschaftspolitischem Hintergrund wird in diesem Papier die Frage nach einer sachgerechten Ausrichtung der...

We analyze a number of unstudied aspects of retail electricity competition. We first explore the implications of load profiling of consumers whose traditional meters do not allow for measurement of their real time consumption, when consumers are homogeneous up to a scaling factor. In general,...

Despite all of the talk about "deregulation" of the electricity sector, a large number of non-market mechanisms have been imposed on emerging competitive wholesale and retail markets. These mechanisms include spot market price caps, operating reserve requirements, non-price rationing protocols,...

We empirically test the hypothesis that the discounts offered by firms to consumers who purchase tickets in advance increase with the intensity of competition. We develop a new measure of competition for which we use the proximity (in departure time) of a given flight to its competitors to infer...

Recovery of stranded costs is perhaps the most litigious issue encountering regulators in promoting competition in United States and European utility industries. We build a dynamic model of Cournot competition which takes into account a particular regulatory mechanism regularly employed in...

In this paper we have developed a model which analyzes price competition in the deregulated Spanish electriciy market. This model is the first to take explicitly into account the mechanism designed in the recent Spanish electricity law for settling stranded costs payments. We show that stranded...

I study the role of purely financial players in electricity markets, where they trade alongside physical buyers and sellers. In this context, physical sellers intertemporally price discriminate, leading to price differences that financial traders arbitrage, thus restricting producers' market...

All but one of U.S. power markets administered by Regional Transmission Operators require that sellers of power to end-users must own or have contractual access to generation capacity sufficient to cover their loads. The exception is the Electricity Reliability Council of Texas (ERCOT), which...
