This paper reports an experiment designed to assess the effects of a rotation in the marginal cost curve on convergence in a repeated Cournot triopoly. Increasing the cost curve’s slope both reduces the serially-undominated set to the Nash prediction, and increases the peakedness of earnings. We observe higher rates of Nash equilibrium play in the design with the steeper marginal cost schedule,...
امروزه مصرف کنندگان به دنبال محصولاتی هستند که ضمن رفع گرسنگی و احتیاجات غذایی، برای سلامتی انسان نیز مفید باشند. غذای فراسودمند به غذایی گفته می شود که حاوی ترکیباتی است که بر یک یا چندین عملکرد در بدن انسان اثر مثبت دارند. اخیرِاً اثبات شده است که برخی از لیپیدها علاوه بر داشتن ارزش تغذیه ای، می توانند دارای اثرات مثبتی بر سلامتی انسان باشند. از جمله ترکیبات فراسودمند لیپیدی می توان به اسیدهای ...
We characterise the relationship between two network based oligopoly markets when local players share the interconnection’s ownership. To that purpose, we analyse the case of the Bacton (UK)-Zeebrugge (Belgium) natural gas pipeline using Vector Auto-regressive Representation techniques. We conclude that there is a threshold of capacity deployment after which the two local markets split. As a re...
The class of consistently competitive games canonically unifies Prisoner’s Dilemmas, contests, auctions, and Bertrand competitions. If those games are repeated infinitely, the players have to negotiate about the strategies that are to be repeated infinitely. These negotiations, however, are perturbed by the possibility that players make defective proposals (defective proposals are sensibly not ...
Does Equal Pay Legislation Reduce Labour Market Inequality? This paper considers a labour market model of monopsonistic competition with taste-based discrimination against minority workers to study the effect of equal pay legislation on labour market inequality. When the taste for discrimination is small or competition is weak, the policy removes job segregation and the wage gap completely. How...
In this paper, we develop a vertically differentiated duopoly model where a high-quality producer competes against a low-quality producer, a la Cournot competition. The high-quality firm has both a new technology and an obsolescent technology. After first deciding whether to license, the firm then chooses which of the two technologies to license. We show that, irrespective of the licensing cont...
We conduct experiments testing the relationship between excess capacity and pricing in repeated Bertrand-Edgeworth duopolies and triopolies. We systematically vary the experimental markets between low excess capacity (suggesting monopoly) and no capacity constraints (suggesting perfect competition). Controlling for the number of firms, higher production capacity leads to lower prices. However, ...
A given number of single-product oligopolists locate in one of two separate market-places, which consumers access at a cost. Firms set prices and the CES consumers choose purchases at one or both market-places. Firm agglomeration in one market-place produces positive profits because of product differentiation. But under various assumptions, geographical separation of firms produces prices analo...
We study how competition affects innovation (and welfare) when firms compete both in the product market and in innovation development. This relationship is complex and may lead to scenarios in which a lessening of competition increases R&D and consumer welfare in the long run, contradicting arguments provided by antitrust agencies in recent merger cases. We provide conditions for when a merger ...
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 an evolutionary (learning) game into a duopoly model with product differentiation on the Hotelling li...
