A descontinuidade em banco comercial privado nacional: um estudo de caso: o COMIND

O objetivo deste estudo busca identificar e descrever fatos indicadores da causa de descontinuidade do Banco Comércio e Indústria de são Paulo S.A. - COMIND. Aos 31 de dezembro de 1974, o COMIND assumira a posição do 6ª maior banco privado do país e, aos 19 de novembro de 1985, transformou-se na maior falência da história bancária brasileira. A descrição delineará o perfil da sua trajetória de existência, enfatizando o período da sua última gestão. Utilizando-se de documentação indireta, tais como relatórios de Comissão de Inquérito, de auditoria e de CPI da câmara, procurou-se a consistência das informações pertinentes ao caso em estudo. Os resultados obtidos propiciaram ordenar os fatos e proceder um cruzamento com causas de falências bancárias ocorridas, preponderantemente, nos E.U.A. As conclusões da pesquisa se basearam nas evidências resultantes de análise comparativa, culminando com o entendimento de que houve uma administração bancária frágil, inepta e centralizadora, além de omissão por parte da auditoria independente.

Factors affecting the technical efficiency of production of the Brazilian banking system : a comparison of four statistical models in the context of data envelopment analysis

This paper uses an output oriented Data Envelopment Analysis (DEA) measure of technical efficiency to assess the technical efficiencies of the Brazilian banking system. Four approaches to estimation are compared in order to assess the significance of factors affecting inefficiency. These are nonparametric Analysis of Covariance, maximum likelihood using a family of exponential distributions, maximum likelihood using a family of truncated normal distributions, and the normal Tobit model. The sole focus of the paper is on a combined measure of output and the data analyzed refers to the year 2001. The factors of interest in the analysis and likely to affect efficiency are bank nature (multiple and commercial), bank type (credit, business, bursary and retail), bank size (large, medium, small and micro), bank control (private and public), bank origin (domestic and foreign), and non-performing loans. The latter is a measure of bank risk. All quantitative variables, including non-performing loans, are measured on a per employee basis. The best fits to the data are provided by the exponential family and the nonparametric Analysis of Covariance. The significance of a factor however varies according to the model fit although it can be said that there is some agreements between the best models. A highly significant association in all models fitted is observed only for nonperforming loans. The nonparametric Analysis of Covariance is more consistent with the inefficiency median responses observed for the qualitative factors. The findings of the analysis reinforce the significant association of the level of bank inefficiency, measured by DEA residuals, with the risk of bank failure.

Co-ordination failure, moral hazard and sovereign bankruptcy procedures

We study a model of sovereign debt crisis that combines problems of creditor coordination and debtor moral hazard. Solving the sovereign debtor's incentives leads to excessive 'rollover failure' by creditors when sovereign default occurs. We discuss how the incidence of crises might be reduced by international sovereign bankruptcy procedures and relate this to the current debate on revising international financial architecture.
