How realistic is the supply/demand equilibrium story?: A simple demonstration of false trading and its implications for market equilibrium
نویسنده
چکیده
Transactions at non-equilibrium prices are “false trades”. Under standard assumptions, markets without false trading produce Pareto-efficient outputs. This paper demonstrates graphically the complications created when false trades occur, showing that quantities produced deviate from Pareto-efficient quantities except under unique conditions. In a general equilibrium framework, this spills over to cause Pareto-inefficient results in other markets as well. These observations call into question the use of standard supply-and-demand equilibrium theory as a starting point for policy analysis. © 2007 Elsevier Inc. All rights reserved.

متن کاملHow Does Large-scale Wind Power Generation Affect Energy and Reserve Prices?
Intermittent nature of wind power faced ISO and power producers with new challenges. Wind power uncertainty has increased the required reserve capacity and deployment reserve. Consequently, large-scale wind power generation increases ISO costs and consequently reserve prices. On the other hand, since wind power producers are price taker, large-scale wind power generation decreases residual dema...
