This paper is about the Spanish Electricity Market after liberalisation. The analysis focuses on finding if the market has become as a Perfect Competition regimen or on the other side, he still continues as a regimen in wich a high output supply concentration and high power market appears, not...

This paper questions the existing notion of competition prevalent in economic theory. It is shown that the prevalent idea of competition is incompatible with economic development. Fair competition, this paper argues, ought to be understood in context. The paper ends by providing some preliminary...

We examine a model of price competition with strictly convex costs where the firms simultaneously decide on both price and quantity, are free to supply less than the quantity demanded, and there is discrete pricing. If firms are symmetric then, for a large class of residual demand functions,...

In this paper, we study asymmetric information economies consisting of both non-negligible and negligible agents and having ordered Banach spaces as their commodity spaces. In answering a question of Herves-Beloso and Moreno-Garcia in [17], we establish a characterization of Walrasian...

We develop models of markets with procrastinating consumers where competition operates - or is supposed to operate - both through the initial selection of providers and through the possibility of switching providers. As in other work, consumers fail to switch to better options after signing up...

In a standard financial market model with asymmetric information with a finite number N of risk-averse informed traders, competitive rational expectations equilibria provide a good approximation to strategic equilibria as long as N is not too small: equilibrium prices in each situation converge...

We analyze the effect of price caps on equilibrium production and welfare in oligopoly under demand uncertainty. We find that high price caps always increase production and welfare as compared to the situation without price cap. Price caps close to marginal cost may lead to zero production,...

We analyze a market game where firms choose capacities under uncertainty about future market conditions and make output choices after uncertainty has unraveled. We show existence and uniqueness of equilibrium under imperfect competition and establish that capacity choices by strategic firms are...

The purpose of this paper is to provide a comparison of three types of competition in a differentiated industry: Cournot, Bertrand, and monopolistic competition. This is accomplished in an economy involving one sector and a population of consumers endowed with separable preferences and a given...

Previous theoretical researches show that learning from good performers yields intense competition and results in the low profitability of firms. These researchers do not take into account differentiation strategies being referred as a useful strategic tool to mitigate competition. We introduce...
