We study the link between lobbying and industrial concentration. Using data for past 20 years in US, we show how increases when an industry becomes more concentrated, using mergers as shocks to This holds true both expenditures on federal well campaign contributions. Results are line with predictions of a model where is akin public good incumbents, thus typically underprovided, while merger sol...

Deregulation policy has caused some changes in the concepts of power system reliability assessment. This paper deals with generation reliability evaluation in perfect competition power market using market economic concepts and its dynamic. Also, because of power markets and generators’ forced outages stochastic behavior, Monte Carlo Simulation (MCS) is used in this research. Generation reliabil...

in this paper, the concept of conjectural variation (cv) is used to specify optimal generation decision for generation companies (gencos). the conjecture of genco is defined as its belief or expectation about the reaction of rivals to change of its output. using cv method, each genco has to learn and estimate strategic behaviors of other competitors from available historical market operation da...

deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. in this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. also, because of power market and generators’ forced outages stochastic behavior, monte carlo simulation is used for reliability evaluation. generation reli...

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...

Regulatory reform in the Nordic electricity-supply markets has resulted in a single integrated Nordic electricity market. This paper performs an econometric study of market power in the spot market of Nord Pool, the joint Nordic power exchange. I use a dynamic extension of the Bresnahan-Lau model, and weekly data for the period from 1996 through April 1999. To my knowledge, this is the first st...

The main objective of this paper is to evaluate the structure of the Iranian banking system and to measure the market power factor based on the Boone approach. In this paper, we investigated the Iranian organized money market, including 18 banks operating in the period of 2008-2015. To calculate the marginal cost (MC), we used a Translog Stochastic Frontier Cost Function. Findings based on the ...

The paper presents an empirical model of the “make or buy” decision faced by independent power producers (IPPs) in restructured U.S. wholesale electricity markets. The model is applied to plant-level data that track the investment decisions of major IPPs from 1996 to 2000, yielding estimates of each firm’s investment cost and expected profit functions. The estimates are used to evaluate the eff...
