Entry costs and quality of business environment: a critical analysis
Zylbersztajn, Decio;
RAM. Revista de Administra??o Mackenzie , 2010, DOI: 10.1590/S1678-69712010000500008
Abstract: transaction costs are the costs to protect property rights. institutions are shaped in order to control transaction costs in society. studies have been developed to measure transaction costs both at the macro and microeconomic levels. entry costs, i.e., the cost to start up a new business are considered a proxy for business environment quality, being also interpreted as a proxy to transaction cost measurement. this paper presents new elements in order to amplify the potential of research in business environment, particularly business entry costs. it stresses the limitation related to two theoretical points: first, the near decomposability of one complex transaction, and second, the complementarity between ex-ante and ex-post transaction costs, both related to the methodology adopted to measure business entrance costs.
Papel dos contratos na coordena??o agro-industrial: um olhar além dos mercados
Zylbersztajn, Decio;
Revista de Economia e Sociologia Rural , 2005, DOI: 10.1590/S0103-20032005000300001
Abstract: this essay departs from the question about the limited adoption of the contractual approach in the field of agricultural economics in brazil. it discusses the relevance of the contractual approach to the theory of the firm, presents the evolution of the studies of coordination in food chains in brazil and abroad, and concludes suggesting a research and educational agenda for applied agricultural economics.
Organiza??o ética: um ensaio sobre comportamento e estrutura das organiza??es
Zylbersztajn, Decio;
Revista de Administra??o Contemporanea , 2002, DOI: 10.1590/S1415-65552002000200008
Abstract: the main objective of the essay is to discuss the theme of ethics and organizations under the lenses of the new institutional economics. given the importance of ethics and social responsibility for organizations, the study suggests the risk associated to the benign approach of cooperation based on the assumption of absence of opportunism. also discusses the problem of survival of the ethical corporation, in face of the existence of non-ethical behavior of the competition. the study concludes that internal organization should be architected to provide the incentives and align the behavior of stakeholders and stockholders. it also concludes that institutional evolution should affect the capacity for the socially responsible organization survive in the market place.
O episódio de Freud com a cocaína: o médico e o monstro
Gurfinkel, Decio;
Revista Latinoamericana de Psicopatologia Fundamental , 2008, DOI: 10.1590/S1415-47142008000300006
Abstract: the aim of this paper is to evaluate of the possible "remaining portions" of freud's cocaine episode on the creation of psychoanalysis creation. specifically, the author provides a critical, analytical and retrospective examination of this episode. the result of the evaluation calls attention to four elements: the appearance of freud as a psychiatrist and pharmacologist and the gradual abandonment of this path. but addction eventually became an object of research and self-administration was used as a method of research. in addition, the belief in a model of a magical cure was tested and subsequently abandoned.

The Scattering Theory of CP Violation
Decio Cocolicchio
Physics , 1997,
Abstract: The mixing effects and the $CP(T)$--violating formalism for Kaon, B--mesons and similar unstable oscillating systems, are recovered by means of a method based on the properties of the complex singularities in the $S$--matrix theory with unstable intermediate states. General $q^2$--dependent relations for CP--asymmetries are then introduced.
Logical aspects of quantum (non-)individuality
Decio Krause
Physics , 2008,
Abstract: In this paper I consider some logical and mathematical aspects of the discussion of the identity and individuality of quantum entities. I shall point out that for some aspects of the discussion, the logical basis cannot be put aside; on the contrary, it leads us to unavoidable conclusions which may have consequences in how we articulate certain concepts related to quantum theory. Behind the discussion, there is a general argument which suggests the possibility of a metaphysics of non-individuals, based on a reasonable interpretation of quantum basic entities. I close the paper with a suggestion that consists in emphasizing that quanta should be referred to by the cardinalities of the collections to which they belong, for which an adequate mathematical framework seems to be possible.
Determinantes dos arranjos contratuais: o caso da transa??o produtor-processador de carne bovina no Uruguai
Mondelli, Mario;Zylbersztajn, Decio;
Revista de Economia e Sociologia Rural , 2008, DOI: 10.1590/S0103-20032008000300010
Abstract: what are the determinants of the commercial channel choice in the beef producers-processors transactions? the question refers to the coordination and production control problem associated to changes in consumer's awareness of specific attributes in food products. two contractual arrangements coexist in this transaction: direct-contracting and broker-induced transactions transaction cost economic offers helpful insights to understand the reason for the development and adaptations of different contractual arrangement moved by transaction cost economizing perspective. the empirical analysis is focused in the uruguayan beef agro-industrial system. analysis integrates (i) institutional and organizational changes in the beef industry; (ii) based on the analysis of the transaction dimensions (frequency, asset specificity and uncertainty) we address hypothesis of the determinants of the contractual arrangement in the beef producers-processors transaction; and (iii) we run a statistical test of the hypotheses based on a logit model. we used a panel data with producers-processors transaction from uruguayan agricultural bureau (77,000 transactions). we confirm the hypotheses of the determinants of the contractual arrangement choice. the probability of a transaction being aligned with the direct contractual arrangement increase in transaction with higher asset specificity (i.e., young steer), lower distance between the producer and the processor, and with higher frequency of transaction.
Stability of contracts in the Brazilian wine industry
Zylbersztajn, Decio;Miele, Marcelo;
Revista de Economia e Sociologia Rural , 2005, DOI: 10.1590/S0103-20032005000200008
Abstract: a variety of contracts between wineries and grape growers are observed in brazil. this study addresses the concept of coordination of food chains, particularly the stability of contractual relationships. a qualitative analysis of industry-farmers contracts is presented, followed by a quantitative analysis testing transaction cost economics-based hypothesis. scale, location, age of vineyard, and the cooperative organizational form are addressed in terms of the effect on the stability of contracts. vertical and horizontal coordination are addressed. data come from a sample of 139 grape-growers that supplied 10 major wineries. the results show that more stable contracts or vertical integration are characteristic of high quality wine production, where the need for strict contractual coordination is more relevant, i.e. risk of hold up losses is larger. we test the hypothesis that site specificity and quality-related specific investments are associated with more stable contractual architectures. farmers' cooperatives present poorer performance but tend to hold more stable relationships with their members, possibly the result of adverse selection, since specialized farmers prefer to maintain contracts with investor-owned wineries, instead of farmers' cooperatives. conclusions are presented in the final part.
