Decentralization and education performance: a first view to the Brazilian process

This paper analyses the impact of the decentralization in educational system that is taking place in Brazil in the last decade, as a result of several laws that encourage municipalities to invest in fundamental education. The proficiency tests undertaken by the government allows to follow some public schools in two points in time. Therefore we were able to create an experimental group with the schools that were under state system in the SAEB exam and have migrated to the municipality system by the time of Prova Brasil and a control group with the schools that were under the state system between the two exams and compare the difference in their results using a fixed effect panel data analysis. The difference in difference estimator indicates that there is no significant change in the performance of the students.

Test score disclosure and school performance

In this paper we test whether the disclosure of test scores has direct impacts on student performance, school composition and school inputs. We take advantage of the discontinuity on the disclosure rules of The National Secondary Education Examination (ENEM) run in Brazil by the Ministry of Education: In 2006 it was established that the 2005 mean score results would be disclosed for schools with ten or more students who took the exam in the previous year. We use a regression discontinuity design to estimate the e ects of test disclosure. Our results indicate that private schools that had their average scores released in 2005 outperformed those that did not by 0.2-0.6 in 2007. We did not nd same results for public schools. Moreover, we did not nd evidence that treated schools adjusted their inputs or that there was major changes in the students composition of treated schools. These ndings allow us to interpret that the main mechanism driving the di erences in performance was the increased levels of students', teachers' and principals' e ort exerted by those in schools that had scores publicized.

Are defaults a family affair?: the relationship between kinship and microloan performance

A partir de uma grande base de dados fornecida por uma instituição de microcrédito do nordeste brasileiro, a relação entre parentesco e inadimplência é analisada. O presente trabalho mostra evidências de que o parentesco entre membros de um grupo solidário afeta positivamente a adimplência. Grupos em que todos os membros possuíam algum laço de parentesco entre si apresentaram uma probabilidade 24% menor de inadimplência do que grupo sem esses laços. Além disso, quando considerado apenas o primeiro empréstimo, grupos com 100% de parentesco entre os membros apresentaram uma probabilidade 45% menor de inadimplência em comparação com membros sem relações de parentesco. Os resultados deste trabalho também mostram que há uma relação negativa entre parentesco e probabilidade de mudança na formação de um grupo solidário. Essas análises permitem fazer inferências acerca dos mecanismos pelos quais o parentesco afeta o desempenho do microcrédito. Os resultados sugerem que o parentesco possui um benefício maior no processo de autosseleção do grupo. Além disso, os resultados também sugerem que o impacto positivo do parentesco nas atividades de automonitoramento compensa o enfraquecimento das atividades de enforcement.

The relationship between board of director's nationality diversity and financial performance

Companies are moving to a more international structure; going into new markets and having an increased competition in all fronts. Therefore, the practices that lead companies to a more efficient and competitive position are praised.

This new structure with several different nationalities working together poses new challenges for companies. Understanding if and how a more diverse has a relationship with financial performance is the starting point for better managing this new corporate structure.

Demand and supply: price elasticities and corporate performance in the UK

This paper investigates the relationship between consumer demand and corporate performance in several consumer industries in the UK, using two independent datasets. It uses data on consumer expenditures and the retail price index to estimate Almost Ideal Demand Systems on micro-data and compute timevarying price elasticities of demand for disaggregated commodity groups. Then, it matches the product definitions to the Standard Industry Classification and uses the estimated elasticities to investigate the impact of consumer behaviour on firm-level profitability equations. The time-varying household characteristics are ideal instruments for the demand effects in the firms' supply equation. The paper concludes that demand elasticities have a significant and tangible impact on the profitability of UK firms and that this impact can shed some light on the relationship between market structure and economic performance.

Effects of capital structure on markups and competitive performance : evidence from Portugal

Este estudo avalia os efeitos da estrutura de capital nas margens de lucro e no desempenho competitivo. Aplica teorias relativas à contra ciclicidade das margens de lucro, e aos resultados do mercado do produto de Chevalier e Scharfstein (1996), a dados portugueses, seguindo a metodologia de Campello (2001). Utilizando dados de painel de empresas pertencentes à indústria transformadora Portuguesa, a análise fornece evidencia para a contra-ciclicidade de margens de lucro e de um efeito conjunto de dívida e recessão económica nas margens de lucro. Tendo por base o recenseamento de empresas Portuguesas, a análise não fornece evidência de uma relação significativa entre a estrutura de capital e o desempenho competitivo.
