This paper analyses the extent of gasoline price differences among provinces in Argentina during the period 1998-2000, and tries to impute those differences to price discrimination and non-price discrimination causes. It also tries to measure the effects of those differences on quantities and...

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. It is primarily...

This paper develops an oligopoly model with firms that may potentially be state-owned or privately owned 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...

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...
