Working Paper Bank debit taxes: yield vs. disintermediation(2003) Kirilenko, Andrei; Summers, Victoria P.Working Paper Education and health: evaluating theories and evidence(2006) Cutler, David M.; Lleras-Muney, AdrianaThere is a large and persistent association between education and health. In this paper, we review what is known about this link. We first document the facts about the relationship between education and health. The education 'gradient' is found for both health behaviors and health status, though the former does not fully explain the latter. The effect of education increases with increasing years of education, with no evidence of a sheepskin effect. Nor are there differences between blacks and whites, or men and women. Gradients in behavior are biggest at young ages, and decline after age 50 or 60. We then consider differing reasons why education might be related to health. The obvious economic explanations - education is related to income or occupational choice - explain only a part of the education effect. We suggest that increasing levels of education lead to different thinking and decision-making patterns. The monetary value of the return to education in terms of health is perhaps half of the return to education on earnings, so policies that impact educational attainment could have a large effect on population health.Working Paper Bad taxation: disintermediation and illiquidity in a bank account debits tax model(2006) Albuquerque, Pedro H.This paper uses a dynamic general equilibrium model to study the economic effects of bank account debits (BAD) taxation. Australia and various Latin American countries have levied or levy BAD taxes. Aspects such as financial disintermediation, market illiquidity, and impacts on dividend and interest rates are considered. Part of the BAD tax revenue may be fictitious, due to increased interest payments on government debt. The Brazilian BAD tax (CPMF) experience is evaluated. The empirical analysis confirms some theoretical predictions. Incidence base over GDP appears to be sensitive to the tax rate, possibly engendering a Laffer curve. The tax may also cause real interest rates to increase. Furthermore, the deadweight losses are relatively large, even if revenues are small. The theoretical and empirical results suggest that the BAD tax is not adequate for revenue collection.Working Paper Quantity-before-Price Auction: Evaluating the Performance of the Brazilian Existing Energy Market(2008) Moita, Rodrigo; Rezende, LeonardoWorking Paper Policy Preferences for Output Stability before and after Inflation Targeting(2008) Araújo, Eurilton; Pinheiro, TatianaWorking Paper Consumption in South America: myopia or liquidity constraints?(2008) Paz, Lourenço Senne; Gomes, Fábio Augusto ReisIn this paper, we consider Brazil, Colombia, Peru and Venezuela for a study on aggregate consumption behavior, in which we test the life cycle-permanent income hypothesis prediction that consumption growth depends only on interest. Our results suggest that only Venezuelan data supported this prediction. To identify possible reasons for rejection in the other cases, we checked for liquidity constraints, myopia and perverse asymmetry. We found that for Brazil the perverse asymmetry was rejected, whereas for Colombia the liquidity constraint hypothesis was rejected. The results were uninformative about Peruvian consumptionWorking Paper Corporate Financial Policies and the Exchange Rate Regime: Evidence from Brazil(2008) Rossi Júnior, José LuizEste trabalho analisa o relacionamento entre a política financeira das empresas e o regime cambial para uma amostra de empresas brasileiras não-financeiras no período de 1996 a 2006. Os resultados indicam que, além de reduzir a proporção da dívida expressa em moeda estrangeira e aumentar a utilização de derivativos, a adoção de um regime de câmbio flutuante leva a um maior casamento monetário entre a ativo e o passivo das firmas. O trabalho mostra que esta melhora no gerenciamento de risco das firmas dá-se, principalmente, nas firmas mais expostas ao risco cambial. Os resultados confirmam que o regime cambial exerce um papel importante na determinação da vulnerabilidade externa das firmas.Working Paper What is the Value of Corporate Social Responsibility? An answer from Brazilian Sustainability Index(2008) Rossi Júnior, José LuizThis paper analyzes using a sample of non-financial Brazilian companies from 2005 to 2007 whether corporate social responsibility has an impact on firm value. Using companies’ Tobin’s Q as a proxy for their market value, the paper finds that firms that compose the Bovespa Corporate Sustainability Index (ISE) are traded with a premium compared to the other publicly traded firms. The result is robust to the inclusion of a set of control variables and the method of estimation. In addition, after controlling for self-selectivity, the results confirm that policies that focus corporate sustainability add value to the firm. The paper indicates that the benefits of corporate social responsibility policies surpass the possible costs implied by the adoption of such policies, leading corporate social responsibility to exert a positive impact on firm value.Working Paper Exchange Rate Exposure, Foreign Currency Debt and the Use of Derivatives: Evidence from Brazil(2008) Rossi Júnior, José LuizThis paper studies the exchange rate exposure and its determinants for a sample of non-financial Brazilian companies from 1996 to 2006. The results show that more than 25% of the firms in the sample have significant exchange rate exposure. Moreover, the results indicate that the number of firms exposed is higher in periods of crisis and under a fixed exchange rate regime. In addition, the results point out that although companies’ international activities, operational hedging and financial policies are important determinants of firms’ foreign exposure, the changes in companies’ exposure that took place when the country moved from a fixed to a floating exchange rate regime were mainly driven by changes in companies’ foreign currency borrowing and the use of derivatives that occurred in the period.Working Paper The Impact of the Distribution of R&D Expenses on Firms’ Motivations to Patent(2008) Barros.
