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 Modelo Multi-Estado de Markov em Cartões de Crédito(2008) RINALDO ARTES; Régis, Daniel EvangelistaModelos multi-estado de Markov são utilizados na área médica para estimar as probabilidades de transição entre, por exemplo, vários estágios de uma doença, podendo o paciente recuperar-se ou morrer. O principal interesse deste trabalho é analisar a aplicação do modelo multiestado de Markov na área de risco associado ao uso de cartões de crédito, aproveitando as características de transições entre diversos estados de relacionamento entre os clientes e as instituições ao longo do tempo e, com isso, gerar modelos de escore para diversos fins. Modelos de regressão logística também são estimados a fim de comparar os resultados com os obtidos pelo modelo multi-estado de Markov.Working Paper A crise política de 2005: Causas estruturais e conjunturais que a explicam(2008) CARLOS ALBERTO FURTADO DE MELOWorking Paper The Effects of Trade Liberalization on Productivity Growth in Brazil: Competition or Technology?(2010) Lisboa, Marcos de Barros; NAERCIO AQUINO MENEZES FILHO; Schor, AdrianaThis paper examines the effects of trade liberalization on productivity growth in Brazil. In contrast with the previous literature, we examine whether this relationship is driven by product or input market effects, by including both output and input tariffs in firm-level productivity regressions and allowing for imperfect competition in the product market. The results show that the reductions of input tariffs were more important to explain the productivity growth that took place during trade liberalization in Brazil. Lower input tariffs may allow firms to access foreign inputs with more advanced technology at lower prices. Moreover, we find that the reduction in input tariffs led to a rise in mark-ups, while the reduction in output tariffs did the opposite.Working Paper Working Paper Métricas de Criação de Valor na Empresa e a Capitalização de Gastos com Pesquisa e Desenvolvimento(2008) ANDREA MARIA ACCIOLY FONSECA MINARDI; Sanvicente, Antonio Zoratto; Souza, Leandro da Silva eO trabalho discute os principais pontos de vista inerentes às normas de contabilidade relativas ao tratamento de despesas de pesquisa e desenvolvimento e avaliação de ativos intangíveis, ou seja, relevância para o valor da empresa e confiabilidade dos valores estimados. Descreve as normas vigentes nos Estados Unidos e no Brasil, fazendo também referência aos padrões internacionais de contabilidade. Faz uma revisão de literatura contábil empírica voltada para a determinação da relevância e da confiabilidade da capitalização de gastos com pesquisa e desenvolvimento, e descreve o procedimento adotado num dos artigos analisados para que se estimem: (a) o valor do ativo intangível gerado com pesquisa e desenvolvimento, (b) o prazo de sua vida útil, e (c) a escala de taxas de amortização do ativo assim criado. Essas estimativas seriam indispensáveis para uma empresa que capitalizasse seus gastos de P&D, principalmente para fins de cálculo do capital investido em métricas de criação de valor.Working Paper Inequality and Cost of Electoral Campaigns in Latin America(2008) Bugarin, Mauricio Soares; Portugal, Adriana; Sakurai, Sergio NaruhikoThis chapter presents a theoretical and an empirical analysis of the effect of inequality on the cost of electoral campaigns. An electoral competition model suggests that electoral campaigns costs increase with the level of inequality. An econometric analysis of Brazilian 2002 and 2004 elections at the state and municipal levels supports the results of the theoretic model. Moreover, the regressions suggest that the lower the age dispersion and the higher the education dispersion of voters, the more expensive the electoral campaigns. The empirical and theoretic results stress the importance of careful campaign financing regulation in highly-unequal Latin American countries.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, Tatiana
