This paper describes the architecture and uses of an Internet based software platform called PowerWeb. PowerWeb was designed and implemented as a simulation environment for evaluating various power exchange auction markets through experimental investigation. It is designed to host simulations of a competitive “day-ahead” electric energy market in which the participants interact by submitting bi...

How does competition in a firm's product market affect the behavior of its stock? We examine this question in a noisy rational expectations economy in which firms operate under monopolistic competition. Production is subject to productivity shocks and requires capital, raised on a perfectly competitive equity market. Investors observe firms' past profits and collect private information about th...

We consider a market in which capacity-constrained generators compete in scalar-parameterized supply functions to servean inelastic demand spread throughout a transmission constrained power network. The market clears according to a locationalmarginal pricing mechanism, in which the independent system operator (ISO) determines the generators’ production quantities tominimize the reve...

This paper presents an empirical assessment of the degree of competition within the Jamaican banking sector during the period 1998 to 2009. We employ a dynamic version of the Panzar Rosse Model to estimate market power among the sample of banks that constitute over 90 percent of the banking market. Using the conventional statistical tests, we are unable to reject monopoly/perfect collusion for ...

We examine the relationship between market structure and the persistence of US dollar-based sectoral real exchange rates for 14 OECD countries. Our empirical results based on disaggregated data suggest that differences in market structure significantly determine the rates at which deviations from sectoral purchasing power parity decay. Specifically, industries with a larger price-cost margin ar...

Several regions of the U.S. have sought to restructure the electric power industry by separating the potentially competitive generation sector from the natural monopoly functions of electricity transmission and distribution. Under this restructuring scheme, a central authority, which we will refer to as the independent system operator (ISO), is given control over both the transmission system an...

A major concern in the design of wholesale electricity markets is the potential for the exercise of market power by generating unit owners. To better understand the determinants of generating unit owner market power and how it is exercised, this paper derives a model of bidding behavior in a competitive electricity market which incorporates various sources of uncertainty and the impact of the e...

Game theory is the study of mathematical models and cooperation between intelligent rational decision-makers. This paper provides a flexible model to calculate pay-off matrix based on several importance factors. This model is adapted by cooperative game and developed for some competitive advantages sections in pharmaceutical industry. An optimum solution is derived by considering Nash equilibri...

This paper presents a new framework for the day-ahead reactive power market based on the uniform auction price. Voltage stability and security have been considered in the proposed framework. Total Payment Function (TPF) is suggested as the objective function of the Optimal Power Flow (OPF) used to clear the reactive power market. Overload, voltage drop and voltage stability margin (VSM) are inc...
