Sources of comparative advantages in Brazil

Based on the Heckscher-Ohlin-Vanek model, this paper investigates relative factor abundance in Brazil, as revealed by its international trade. We study two different time periods: one characterized by high trade barriers (1980 to 1985) and the trade liberalization period (1990 to 1995). Two alternative methodologies are used: the estimation of factor intensity regressions on net exports and the direct computation of factor content in net exports. In the factor intensity regression, we incorporate technological changes that might have occurred over time, and those turned out to be significant. Both methods yield the same results: the Brazilian international trade reveals relative abundance in capital, land and unskilled labor, and scarcity in skilled labor, with qualitatively equivalent results for the two time periods studied.

Análise dos fatores de convencimento do juízo brasileiro quanto à ocorrência de fraude contábil: um estudo de caso Múltiplo da Gallus, da Encol e do Banco Santos

This work is based on the analysis of three Brazilian cases of condemnation by accounting fraud and financial reports manipulation of data, where we tried to identify if there is condemnation by accounting fraud in Brazil and the main factors considered by the judge to convince them about the accounting fraud. The theoretical reference quoted involves the theory of fraud, the psychology of fraud, examples of financial fraud in foreign companies and Brazilians banks and the law in Brazil regarding fraud and money laundering. The methodology consisted in studies of Brazilian cases with the data collection criteria from three law suits. The methodology used was the Contents Analysis The samples were chosen according to the impact those cases had in Brazil and the facility to access their law suits. Therefore, we chose Gallus Agropecuária S/A, Encol S/A and Banco Santos S/A for a matter of convenience. The evidence indicated that in those three cases, the court was convinced by the accounting fraud due to omission of relevant financial information in the balance sheet, by information provided to the market that didn¿t reflect the healthy of the company (assets written up without the property). It was identified as well that, in those three cases, there was condemnation not only for the accounting fraud per si, but also by the combination of other crimes as money laundering, fraud gang, material and ideological false fraud, and bankruptcy.

Bailey's rule for the welfare of inflation: a theoretical foundation

This paper demonstrates that for a very general class of monetary models (the Sidrauski type models and the cash-in-advance models), Bailey’s rule to evaluate the welfare efect of infation is in deed accurate. The result applies for any technology or preference, if the long-run capital stock does not depend on the ination rate. In general, a dynamic version of Bailey’s rule is established. In particular, the result extends to models in which there is a banking sector that supplies money substitutes services. A dditionally, it is argued that the relevant money demand concept for this issue- the impact of in ination under welfare- is the monetary base.

Participação das mulheres no conselho de administração e diretoria, valor e desempenho das companhias brasileiras de capital aberto

Este trabalho tem como objetivo identificar se a presença de mulheres no conselho de administração e diretoria gera impacto no valor e desempenho das empresas brasileiras de capital aberto. Em geral, a literatura sugere que a participação feminina no conselho de administração e em cargos de diretoria tende a gerar valor e desempenho superior. Este trabalho realiza um estudo inédito no Brasil, analisando 658 empresas de capital aberto no período de 2002 a 2009. Os resultados indicam que não existe uma relação estatisticamente significativa entre presença de mulheres no conselho de administração e em cargos de diretoria para o valor das empresas, mas existe uma relação negativa entre presença de mulheres no conselho e desempenho das empresas.
