Restructuring in the power industry is followed by splitting different parts and creating a competition between purchasing and selling sections. As a consequence, through an active participation in the energy market, the service provider companies and large consumers create a context for overcoming the problems resulted from lack of demand side participation in the market. The most prominent ch...

In this paper capacity withholding in an oligopolistic electricity market that all Generation Companies (GenCos) bid in a Cournot model is analyzed and the capacity withheld index, the capacity distortion index and the price distortion index are obtained and formulated. Then a new index, Distortion-Withheld Index (DWI), is proposed in order to measure the potential ability of market for capacit...

Many attribute the rise in obesity since the early 1980s to the overconsumption of fast food. A dynamic model of a differentiated-product industry equilibrium shows that a firm with market power will price below marginal cost in a steady-state equilibrium. A spatial hedonic pricing model is used to test whether fast food firms set prices in order to exploit their inherent addictiveness. The res...

The purpose of this study is to examine the terms "perfect" and "imperfect" competition in market structure from an Islamic economic perspective. This employed a qualitative approach library research as its methodology. results literature review indicate that perfect has close relationship with concept. proximity reflected price, which determined according hadith Prophet Muhammad by supply dema...

This paper studies the impacts of renewable energy support policies on energy prices, fossil fuel supply and thus carbon emissions and climate change. We show that the impacts are highly dependent on capacity constraints of renewable energies and market power in the fossil fuel sector. We differentiate renewable energies by whether they face production capacity constraints (solar vs. biofuels) ...

This paper examines the presence of labour market imperfections in France, that lead to power on side either firms or their workforce, and investigates role import competition as a possible discipline device. Using information large panel French manufacturing firms, we find Chinese lowers positive gap between actual wages level would prevail under perfect competition, thus strengthening firms’ ...

The Power TAC is a competition-based simulation of an electricity market. The goal of the competition is to test retailer (broker) strategies in a competitive environment. Participants create broker agents that trade electricity. In this paper we describe our broker, which we created as a participant of the 2014 Power TAC competition. We describe the strategies for two main components of the ga...

Our goal in this paper is to study the market impact in a market in which order flow is autocorrelated. We build a model which explains qualitatively and quantitatively the empirical facts observed so far concerning market impact. We define different notions of market impact, and show how they lead to the different price paths observed in the literature. For each one, under the assumption of pe...

Competition is an increasingly important theme in telecommunications policy. It has been credited with expanding services, lowering prices, and stimulating innovation. (Jamison et al. 2009) But competition can raise difficult challenges for telecommunications policy makers and regulators. One of these challenges is determining the optimal mix of market and regulatory involvement in determinatio...

Many researchers show that “market institutions” are an ideal means to exchange and allocate resources under the assumptions of perfect and symmetric information and perfect competition. However, in the real world, we observe many instances in which these assumptions are not satisfied due to imperfect competition, incomplete information, transaction costs, and externalities. In this study we fo...
