    Description: This paper is about a model of Bertrand competition in a homogeneous-good market with free entry of identical firms and variable returns to scale. If the optimum number of active firms in the market is two or more, and the number of active firms is equal to that optimum number, then Bertrand equilibrium exists for that optimum number, and it does not exist if the number of active firms is less than the optimum. The model, however, does not rule out the existence of Bertrand equilibria with more active firms than the optimum number. Finally, when the optimum number of active firms in the market is one, Bertrand equilibrium does not exist.

    Description: Este trabajo propone un procedimiento para evaluar la posible existencia de correlación negativa entre complejidad fonológica, morfológica y sintáctica de diferentes idiomas. El procedimiento se basa en el uso de coeficientes de correlación parcial, variables instrumentales y sistemas de ecuaciones simultáneas, y se lleva a cabo sobre datos tomados de la fábula “El viento norte y el sol”, traducida a 40 idiomas distintos. La complejidad fonológica se mide por el número de fonemas por sílaba, la complejidad morfológica por el número de sílabas por palabra, y la complejidad sintáctica por el número de palabras por frase. Luego de controlar por fenómenos relacionados con factores geográficos y endogeneidad estadística, se llega a la conclusión de que la complejidad fonológica está negativamente correlacionada con la complejidad morfológica, y que esta, a su vez, está negativamente correlacionada con la complejidad sintáctica. Estos resultados pueden relacionarse con la llamada “ley de Menzerath”.

    Description: 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 useful for the estimation of the demands of several goods of the same industry or group of products. The characteristics of the model are compared to other existing alternatives (logarithmic, translog, AIDS and QUAIDS demand systems). The model is finally applied to estimate the demands for several carbonated soft drinks in Argentina, and its results are presented, together with the ones obtained with the other estimation methods.

    Description: El objetivo de este trabajo es reseñar las teorías económicas que sirven de sustento a las recomendaciones de política respecto de la propiedad y la regulación de los servicios de infraestructura, y tratar de combinarlas a fin de poder evaluar las ventajas y desventajas de los distintos esquemas alternativos de organización de dichos servicios (empresa pública, empresa privada con regulación por costos, regulación por incentivos, desregulación). Usando como criterios de evaluación los conceptos de eficiencia, equidad y compatibilidad de incentivos, se llega a la conclusión esperable de que ningún esquema es óptimo en todas las dimensiones, pero también surgen ciertas advertencias y recomendaciones para la adopción de esquemas de organización mixtos.

    Description: 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 perfect legal enforceability, the different alternative damage rules (based on expectation or reliance damages, with or without performance excuses) are able to induce an efficient performance by the contracting parties. But we also find that, if legal enforceability is imperfect, then a rule based on expectation damages with an excuse for impossibility of performance is able to work more efficiently than the other alternative damage rules.

    Description: 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 we find a positive and statistically significant relationship between per-capita income and r-dropping, and between per-capita income and the presence of the cot-caught merger, and a negative and statistically significant relationship between per-capita income and the pin-pen merger. No statistically significant relationship is found, however, between per-capita income and the presence of a father-bother merger or split.

    Description: This paper presents a version of the proportionally calibrated almost ideal demand system (PCAIDS) model, useful for merger simulations, which can be econometrically estimated using price data for two firms in a market. The model is then applied to a database of the Argentine gasoline market, and its results are compared to the ones obtained with other alternative specifications.

    Description: This paper presents a model of the penalty-kick game between a soccer goalkeeper and a kicker, in which there is uncertainty about the kicker's type (and there are two possible types of kicker). To find a solution for this game we use the concept of Bayesian equilibrium, and we find that, typically, one of the kicker's types will play a mixed strategy while the other type will choose a pure strategy (or, sometimes, a restricted mixed strategy). The model has a simpler version in which the players can only choose between two strategies (right and left), and a more complex version in which they can also choose a third strategy (the center of the goal). Comparing the incomplete-information Bayesian equilibria with the corresponding complete-information Nash equilibria, we find that in all cases the expected scoring probability increases (so that, on average, the goalkeeper is worse off under incomplete information). The three-strategy model is also useful to explain why it could be optimal for a goal keeper never to choose the center of the goal (although at the same time there were some kickers who always chose to shoot to the center).

    Description: El presente trabajo presenta un método prospectivo simplificado que sirve para estimar incrementos y reducciones de precios esperados, asociados con casos antitrust de prácticas colusivas y de abusos de posición de dominio en los cuales no resulta posible comparar datos reales de situaciones alternativas competitivas y anticompetitivas. Los incrementos y reducciones calculadas sirven a su vez para estimar daños (y, eventualmente, multas e indemnizaciones) relacionados con los casos en cuestión. El método aparece ilustrado con datos provenientes del mercado argentino de cierto insumo petroquímico.
    Description: This paper develops a simplified prospective method to estimate expected price increases and reductions, associated with antitrust cases of collusion and abuse of dominance, in which it is not possible to compare real data under alternative competitive and anticompetitive situations. The calculated price increases and reductions are useful to estimate damages (and, eventually, fines and compensations) related to the cases under analysis. The method is illustrated with data from the Argentine market of a certain petrochemical input.
