a r t i c l e i n f o In competitive product markets, repeated interaction among producers with similar economic characteristics would be expected to result in convergence of their behaviors. If convergence does not occur, it raises fundamental questions related to the sustainability of heterogeneous competitive strategies. This paper examines the prices submitted to the British wholesale elect...

electricity price predictions have become a major discussion on competitive market under deregulated power system. but, the exclusive characteristics of electricity price such as non-linearity, non-stationary and time-varying volatility structure present several challenges for this task. in this paper, a new forecast strategy based on the iterative neural network is proposed for day-ahead price...

Rising prices in the German wholesale electricity market have spurred discussions about the potentials and the abuse of market power. Particularly since the introduction of emission certificates, electricity prices increased continuously closely related to rising certificate prices. The oligopolistic structure of the German market with four major players owning 90% of the capacities (Bundeskart...

the new competitive environment changes the paradigm of power system operation. in the transmission area, open access process provides fair accessibility for all market participants. congestion management is one of the most important side effects of this new process. this paper proposes a new approach for congestion management which is based on both active and reactive re-dispatch of the networ...

due to uncertain nature of wind and photovoltaic power units, the participation of this units in electricity markets is subjected to significant deviation penalties. this issue leads to despondency or even admission of these units in the competitive environment. with regard to this fact that the low deviations are available when predictions are performed in a short-term horizon and also distrib...

We show that when health care providers have market power and engage in Cournot competition, a competitive upstream health insurance market results in over-insurance and over-priced health care. Even though consumers and firms anticipate the price interactions between these two markets - the price set in one market affects the demand expressed in the other - Pareto improvements are possible. Th...

Previous studies on international marketing have typically asked the question: “how is the demand characterized across countries?” Such analysis is then used to provide guidelines for firms to enter new markets and/or to allocate marketing resources across countries. In order to provide such normative guidelines however, one also needs to analyze the supply-side of the problem, i.e. ask: “what ...

In theory, competitive emission permit markets minimise total abatement cost for any emission ceiling. Permit markets are often imperfectly competitive, however, if they are thin and dominated by large firms. The dominant firm(s) could exercise market power and increase other firms’ costs of pollution control, while reducing their own emission control costs. This paper reports a testbed laborat...
