We consider three models of investments in generation capacity in restructured electricity systems that differ by their underlying economic assumptions. The first model assumes a perfect, competitive equilibrium. It is very similar to the old capacity expansion models even if its economic interpretation is different. The second model (open-loop Cournot game) extends the Cournot model to include...

An observer makes a finite number of observations of an industry producing a homogeneous good. Each observation consists of the market price, the output of individual firms and perhaps information on a firm’s total cost or cost fluctuation. What restrictions on the data set are necessary and sufficient for it to be consistent with the hypothesis that firms in this industry are playing a Cournot...

We model firms’ output decisions in a repeated duopoly framework focussing on three interrelated issues: 1) the role of learning in the adjustment process toward equilibrium, 2) the role of organizational structure in organizational decision making, and 3) the role of changing environmental conditions on learning and output decisions. We model the firm as a type of artificial neural network, wh...

<p style='text-indent:20px;'>This paper investigates a manufacturer's retail outsourcing strategies under different competition modes with economies of scale. We focus on the effects market modes, scale and competitor's behavior decisions, then we develop four game models three modes. Firstly, find channel structure where both manufacturers choose cannot be an equilibrium Cournot competit...

The nature of competition is quite different in network industries as compared to the other, more traditional, ones. The purpose of the present paper is to thoroughly examine the implications of these differences as reflected in the dependence of equilibrium outputs, price and profits on industry concentration. We restrict the analysis to oligopolistic competition amongst firms in a market char...
