Este trabajo desarrolla un modelo de equilibrio de un mercado con diferenciación horizontal de productos en el cual las empresas fijan los precios de las variedades que proveen y, en ciertos casos, alguna de ellas actúa como líder de precios. Dados esos elementos, el trabajo explora qué...

This article analyzes the basic characteristics of the Argentine competition law and the way in which it has been enforced in several important antitrust cases. We begin with a section that introduces the evolution of the law, followed by another section about the basic economic and legal...

This paper develops an oligopoly model with firms that may potentially be public or private, and solves it for different cases in which the number and ownership of those firms vary. The results are then compared in terms of total surplus and consumer surplus, and this comparison produces...

This paper develops a model for demand-system estimations, whose coefficients are own-price Marshallian elasticities and elasticities of substitution between goods. The model satisfies the homogeneity, symmetry and, eventually, adding-up restrictions implied by consumer theory, and is primarily...

This paper develops a game-theoretic model of a contract between a creditor and a debtor where equilibrium depends on the damage rule chosen for breach-of-contract situations, the use of impossibility-of-performance excuses and the level of legal contract enforceability. We find that, under...

This paper uses a least-square regression method that relates per-capita income to four phonetic characteristics (r-dropping, and the so-called father-bother, cot-caught and pin-pen mergers), to study the socio-economic significance of those characteristics in North American English. As a result...
