Contract enforcement and incentive compatibility in large economies with differential information: the role of exact feasibility

We consider exchange economies with a continuum of agents and differential information about finitely many states of nature. It was proved in Einy, Moreno and Shitovitz (2001) that if we allow for free disposal in the market clearing (feasibility) constraints then an irreducible economy has a competitive (or Walrasian expectations) equilibrium, and moreover, the set of competitive equilibrium allocations coincides with the private core. However when feasibility is defined with free disposal, competitive equilibrium allocations may not be incentive compatible and contracts may not be enforceable (see e.g. Glycopantis, Muir and Yannelis (2002)). This is the main motivation for considering equilibrium solutions with exact feasibility. We first prove that the results in Einy et al. (2001) are still valid without free-disposal. Then we define an incentive compatibility property motivated by the issue of contracts’ execution and we prove that every Pareto optimal exact feasible allocation is incentive compatible, implying that contracts of a competitive or core allocations are enforceable.

BISA copyright review: Brazil

This paper is part of the Brazilian branch of the BISA Copyright Review, a research project focused on the intersection of copyright and public interest in Brazil, India and South Africa, funded by the Ford Foundation. The Brazilian contribution is based on interviews with some of the key actors involved with the process of copyright reform initiated by the Brazilian Ministry of Culture in 2007, and provides a thorough picture of the Brazilian copyright policy scenario as of 2008.

Media piracy in emerging economies

Media Piracy in Emerging Economies is the first independent, large-scale study of music, film and software piracy in the developing world, with a focus on Brazil, India, Russia, South Africa, Mexico and Bolivia. Based on three years of work by some thirty-five researchers, the study tells two overarching stories: one tracing the explosive growth of piracy as digital technologies became cheap and ubiquitous around the world, and another following the growth of industry lobbies that have reshaped laws and law enforcement around copyright protection. The report argues that enforcement efforts have largely failed, and that the problem of piracy is better addressed as a failure of affordable access to media in legal markets.

O enforcement contratual no Brasil : uma análise das decisões do TJSP e TJRS sobre o contrato de factoring

A teoria da Nova Economia Institucional atribuiu papel de destaque às instituições, classificando-as como as “regras do jogo” nas sociedades. Uma das vertentes desta literatura foca-se em analisar a relação entre o grau de enforcement ou exigibilidade das decisões proferidas pelo Poder Judiciário e seu impacto no desenvolvimento econômico das nações, em especial, dos países em desenvolvimento. No Brasil, este debate ganha relevância no final da década de 1990 a partir de determinadas pesquisas de cunho social realizadas com magistrados, demonstrando que estes tenderiam a sacrificar a previsibilidade judicial em favor da justiça social. Nesse contexto, certos economistas brasileiros lançam a hipótese da existência de um viés anticredor por parte do Poder Judiciário brasileiro, cuja tendência é a de favorecer a parte devedora, fato que resulta na manutenção das altas taxas de juros no país, bem como na inexistência de um mercado de crédito de longo prazo. Diante deste debate, foi selecionado segmento específico – a atividade de factoring – para se desenvolver pesquisa empírica qualitativa substantiva a fim de se (i) investigar o grau de enforcement das decisões contratuais e (ii) testar a existência ou não de um viés anticredor por parte dos Tribunais de Justiça de São Paulo e do Rio Grande do Sul.

Legal enforcement, collateral and heterogeneity of project financing contracts

This paper employs mechanism design to study the effects of imperfect legal enforcement on optimal scale of projects, borrowing interest rates and the probability of default. The analysis departs from an environment that combines asymmetric information about cash flows and limited commitment by borrowers. Incentive for repayment comes from the possibility of liquidation of projects by a court, but courts are costly and may fail to liquidate. The value of liquidated assets can be used as collateral: it is transferred to the lender when courts liquidate. Examples reveal that costly use of courts may be optimal, which contrasts with results from most limited commitment models, where punishments are just threats, never applied in optimal arrangements. I show that when voluntary liquidation is allowed, both asymmetric information and uncertainty about courts are necessary conditions for legal punishments ever to be applied. Numerical solutions for several parametric specifications are presented, allowing for heterogeneity on initial wealth and variability of project returns. In all such solutions, wealthier individuals borrow with lower interest rates and run higher scale enterprises, which is consistent with stylized facts. The reliability of courts has a consistently positive effect on the scale of projects. However its effect on interest rates is subtler and depends essentially on the degree of curvature of the production function. Numerical results also show that the possibility of collateral seizing allows comovements of the interest rates and the probability of repayment.
