capital asset pricing model (capm) has been among the common models to estimate expected returns rate. since the linearity assumption is considered in the standard version of the capital asset pricing model, estimating beta in nonlinear setting will be inconsistent and bias-oriented. therefore, this study tries to evaluate predictive power of nonlinear capital asset pricing model as well as sta...
reactive power management plays an essential role in the secure operation of the power system as an ancillary service. although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. on the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the secur...
This paper proposes an index for nodal market power detection in power market under locational marginal pricing (LMP). This index is an ex-ante technique to detect the market power. More precisely, this criterion detects the potential of exercising market power regardless of detecting the actual market power. Also it is obvious that pricing and market clearing method affect the potential of exe...
Reactive power as a utility of ancillary service in restructured environment is supplied by Independent System Operator (ISO). Due to the particular importance of optimal pricing strategy in the power market, the study aims to investigate this problem more closely. To this end, first the problems of restructuring, reactive power generation and its associated costs thereof were reviewed and diff...
The main criterion in investment decisions is to maximize the investors utility. Traditional capital asset pricing models cannot be used when asset returns do not follow a normal distribution. For this reason, we use capital asset pricing model with independent and identically asymmetric power distributed (CAPM-IIAPD) and capital asset pricing model with asymmetric independent and identically a...
Reactive power management plays an essential role in the secure operation of the power system as an ancillary service. Although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. On the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the se...
in trading electrical energy in deregulated power systems, violation of operation constraints such as transmission lines flow limits is possible. these conditions have been called “congestion”. one of the most important responsibility of independent system operator (iso) is congestion management in a manner that all the system equipments be operated in their nominal ranges. in this paper, usi...
earnings management has inverted the main objective of financial reporting through the distortion of the actual economic performance of companies and prevented the complete transfer of information to market. given the importance of subject of research, incentives that cause earnings management have been reviewed from various aspects. the main purpose of this research is to examine the relations...

With the development of deregulated power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benefi...
