The use of new energy to generate electricity in the power system and large-scale increase grid connection has led increasingly insufficient regulation, order solve this problem, peak shaving auxiliary service market came into being.This article comprehensively analyzes factors those affect clearing price services: macro include economic policies (renewable electric substitution), technological...

over the past three decades vertical price transmission analysis has been the subject of considerable attention in applied agricultural conomics. it has been argued that the existence of asymmetric price transmission generates rents for marketing and processing agents. retail prices allegedly move faster upwards than downwards in response to farm level pricemovements. this is an important issue...

This paper examines the incentives to exercise market power that generators would face and the different strategies that they would follow if all electricity supplies in Chile were traded in an hourly-unregulated spot market. The industry is modeled as a Cournot duopoly with a competitive fringe; particular care is given to the hydro scheduling decision. Quantitative simulations of the strategi...

A persistent question in industrial economics is the underpinning of the link between market concentration and price. How much of the link can be attributed to market power and how much to market efficiency? This paper develops a theoretical model to address that question. Applied to the US portland cement industry, the model indicates that both impacts matter. In relative terms, however, the m...

As agricultural products move from being economic commodities to quality-differentiated goods, price dispersion within specific markets increases and implicit subsidies from high quality producers to low quality producers are removed. This paper examines how these distributional effects can influence patterns of support and opposition to changes in marketing arrangements. The simple model devel...

accurate and effective electricity price forecasting is critical to market participants in order to make an appropriate risk management in competitive electricity markets. market participants rely on price forecasts to decide on their bidding strategies, allocate assets and plan facility investments. however, due to its time variant behavior and non-linear and non-stationary nature, electricity...

Since the 1980s, the market structure of vaccines has become increasingly oligopolistic, and in some cases, monopolistic. Alongside these supply trends, we see the emergence and growth of group procurement schemes on the demand side of the market. National governments and international organizations procure vaccines on behalf of end users. Two such organizations include the UNICEF Supply Divisi...
