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...

In this paper we show that a homogeneous-product market with multiple Bertrand equilibria becomes a market with a single Bertrand equilibrium when we introduce a small degree of product differentiation. When differentiation tends to zero, that Bertrand equilibrium converges to the unique...

The aim of this paper is to conciliate some conclusions of the economic theories of breach of contract and tort law. The main result is that the two efficient alternatives that tort law identifies (negligence rule and strict liability with a defense of contributory negligence) are mirrored by...

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,...

This paper presents a model of capital accumulation and income distribution that comes from the dynamic interaction between capitalists and workers in an economy. The model is later applied to fit data from the Argentine and the US economies, and to test if they are closer to the implications of...

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 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...
