Income inequality: the role of impatience in a job-search process

This paper investigates the income inequality generated by a jobsearch process when di§erent cohorts of homogeneous workers are allowed to have di§erent degrees of impatience. Using the fact the average wage under the invariant Markovian distribution is a decreasing function of the time preference (Cysne (2004)), I show that the Lorenz curve and the between-cohort Gini coe¢ cient of income inequality can be easily derived in this case. An example with arbitrary measures regarding the wage o§ers and the distribution of time preferences among cohorts provides some quantitative insights into how much income inequality can be generated, and into how it varies as a function of the probability of unemployment and of the probability that the worker does not Önd a job o§er each period.

How does corruption hurt growth? Evidences about the effects of corruption on factors productivity and per capita income

Corruption is a phenomenon that plagues many countries and, mostly, walks hand in hand with inefficient institutional structures, which reduce the effectiveness of public and private investment. In countries with widespread corruption, for each monetary unit invested, a sizable share is wasted, implying less investment. Corruption can also be a burden on a nation’s wealth and economic growth, by driving away new investment and creating uncertainties regarding private and social rights. Thus, corruption can affect not only factors productivity, but also their accumulation, with detrimental consequences on a society’s social development. This article aims to analyze and measure the influence of corruption on a country’s wealth. It is implicitly admitted that the degree of institutional development has an adverse effect on the productivity of production factors, which implies in reduced per capita income. It is assumed that the level of wealth and economic growth depends on domestic savings, foster technological progress and a proper educational system. Corruption, within this framework, is not unlike an additional cost, which stifles the “effectiveness” of the investment. This article first discusses the key theories evaluating corruption’s economic consequences. Later, it analyzes the relation between institutional development, factor productivity and per capita income, based on the neoclassical approach to economic growth. Finally, it brings some empirical evidence regarding the effects of corruption on factor productivity, in a sample of 81 countries studied in 1998. The chief conclusion is that corruption negatively affects the wealth of a nation by reducing capital productivity, or its effectiveness.

A experiência com esporte e educação do Instituto Bola pra Frente: de projeto a tecnologia social

Tecnologia social é um conceito recente, mas sua fundamentação teórica foi inspirada nas idéias do líder indiano Mahatma Gandhi, que popularizou a fiação manual da charkha, uma roca de fiar giratória, como uma solução para diminuir a miséria. O objetivo de uma tecnologia social é produzir um novo patamar de desenvolvimento, que permita o acesso e a produção do conhecimento por toda a população, unindo os saberes acadêmico e popular na busca de soluções sociais inovadoras. O esporte é considerado o maior fenômeno social e cultural da sociedade contemporânea, conectando-se a questões como tempo livre e lazer, mercantilização, espetacularização e inclusão social. Partindo da Grécia Antiga até chegar à sua institucionalização, na Inglaterra do século XIX, o esporte sempre esteve ligado ao contexto educacional. Atualmente, a legislação brasileira reconhece três dimensões do esporte: esporte de rendimento, esporte de participação e esporte educacional. O foco deste estudo é a experiência do Instituto Bola Pra Frente, trabalho social dos tetracampeões mundiais de futebol Jorginho e Bebeto, com esses dois temas: esporte educacional e tecnologia social. Buscamos contribuir para um melhor entendimento desses conceitos e avaliar sua contribuição para a promoção social. Este estudo levanta o histórico e aprofunda os conceitos atuais de tecnologia social: o que caracteriza e quais as implicações de uma tecnologia social, além de experiências de implementação. Como referencial de esporte educacional, esta pesquisa faz um breve histórico do esporte e do futebol, analisando a sua relação com a sociedade, a educação e o terceiro setor. Como referencial prático, este estudo levanta a história do Instituto Bola Pra Frente, aprofundando sua evolução desde 2000, quando foi fundado, no Complexo do Muquiço, no Rio de Janeiro, até os dias atuais, enfatizando quais são os seus conceitos norteadores, sistematizando as informações acerca de sua organização metodológica, metodologia pedagógica e avaliação de impacto social, além da aplicação dos quesitos básicos de uma tecnologia social ao caso do Instituto.

Incerteza e dívida pública prefixada no Brasil

This study analyses the bids¿ dispersion in fixed income government securities auctions issued by the National Treasury of Brazil. We try to estimate the bids¿ variance based on factors that may forecast its movement. We hope to help the security issuer by offering more data before the auction. The basic idea is to relate the market uncertainty with the primary auction of government securities. Results indicates the importance of uncertainty on the bidding decisions. It shows also the need for a liquid secondary market to the selling of long-term fixed income securities.

The influence of materialism on consumption indebtedness in the context of low income consumers from the city of São Paulo

This research is in the domains of materialism, consumer vulnerability and consumption indebtedness, concepts frequently approached in the literature on consumer behavior, macro-marketing and economic psychology. The influence of materialism on consumer indebtedness is investigated within a context that is characterized by poverty and by factors that cause vulnerability, such as high interest rates, limited access to credit and to quality affordable goods. The objectives of this research are: to produce a materialism scale that is well adapted to its environment, characterizing materialism adequately for the population studied; to compare results obtained with results of other studies; and to measure the relationship between materialism, socio-demographic variables, attitude to debt and consumption indebtedness. The primary data used in the analyses were collected from field research carried out in August, 2005 that relied on a probabilistic household sample of 450 low income individuals who live in poor regions of the city of Sao Paulo. The materialism scale, adapted and translated into Portuguese from Richins (2004), proved to be very successful and encourages new work in the area. It was noted that younger adults tend to be more materialistic than older ones; that illiterate adults tend to be less materialistic than those who did literacy courses when they were already adults; and that gender, income and race are not associated with the materialism construct. Among the other results, a logistic regression model was developed in order to distinguish those individuals who have an installment plan payment booklet from those who do not, based on materialism, socio-demographic variables and purchasing and consumer habits. The proposed model confirms materialism as a behavioral variable useful for forecasting the probability of an individual getting into debt in order to consume, in some cases almost doubling the chance of occurrence of this event. Findings confirm the thesis that it is not only adverse economic factors that lead people to get into debt; and that the study of demand for credit for consumption purposes must, of necessity, include variables of a psychological nature. It is suggested that the low income materialistic consumer experiences feelings of powerlessness and exclusion because of the gap that exists between their possessions and their desires. Lines of conduct to combat this marginalization from the consumer society are drawn targeting marketing professionals, public policy makers and vulnerability researchers. Finally, the possibility of new studies involving the materialism construct, which is central to literature on consumer behavior, albeit little used in empirical studies in Brazil, are discussed.

Estado, política cultural e manifestações populares: a influência dos governos locais no formato dos carnavais brasileiros

Apesar das controvérsias sobre a forma como as festas populares têm sido tratadas, é fundamental reconhecer que, além das questões econômicas, elas envolvem um componente social muito importante. Fatores como o fortalecimento de identidade e do sentimento de pertencimento, reforço de laços comunitários, participação popular na formulação e implementação das políticas e ocupação de espaços públicos têm íntima relação com essas festas. Dentro desse cenário está inserida a maior das festas populares brasileiras, o carnaval. Os festejos carnavalescos são estudados nesta Dissertação. A idéia é analisar como o a Administração Pública e o Carnaval estiveram sempre muito próximos, em relações que por vezes eram consensuais e, em outros momentos, bastante conflitantes. Para a realização desta dissertação foram coletados diversos dados públicos, que compõem a parte quantitativa da pesquisa. Os dados qualitativos foram obtidos através de várias entrevistas, com atores governamentais e não-governamentais ligados à festa. Além do aspecto descritivo sobre a atuação dos governos locais em relação aos carnavais citados, este trabalho pretende ampliar uma dimensão pouco explorada nas pesquisas sobre a cultura em geral e sobre o carnaval em especial: a Economia do Carnaval. Os dias de realização da festa geram grandes ganhos financeiros e é fundamental analisar quem, de fato, são os beneficiários através de uma pergunta básica, mas de crucial importância: Carnaval para quem? Esta dissertação visa colaborar com a discussão sobre o papel que os governos locais podem, com algumas medidas, melhorar as condições socioeconômicas dos trabalhadores, criando mecanismos capazes de desconcentrar a renda, reduzindo assim as desigualdades socioeconômicas do país.

Continuidade e descontinuidade administrativa em governos locais: fatores que sustentam a ação pública ao longo dos anos

Esta dissertação estuda a questão da continuidade e descontinuidade de políticas públicas em governos municipais. Apesar do tema ser muito presente na fala e no cotidiano de gestores, pesquisadores, servidores públicos e jornalistas, há poucos estudos que realmente aprofundem como se dão esses fenômenos. Os poucos trabalhos realizados apontam primeiro para o paradoxo democrático da questão ¿ ainda que a descontinuidade seja normalmente considerada indesejável, ela é um dos pressupostos básicos da alternância de poder que a rotina democrática requer. Além disso, há quem aponte que os dois fenômenos possam estar mais ligados do que numa análise superficial. Por último, alguns estudos sugerem que possa haver mais continuidade do que o senso comum levaria a crer, ainda que as explicações para essa realidade ainda estejam pouco elaboradas. É nesta direção que o presente trabalho pretende contribuir. O objetivo principal desta pesquisa foi avançar na compreensão dos fatores que favorecem a continuidade de ações públicas em governos locais no Brasil. Neste sentido, a parte teórica do trabalho incluiu uma revisão de modelos de políticas públicas uitilizados como lente teórica à observação da pesquisa empírica. Também foram revistos alguns textos sobre o local e suas políticas de desenvolvimento, priorizados como objetos de estudo desta dissertação. Foram então realizados três estudos de caso de diferentes políticas de desenvolvimento local. As iniciativas estudadas foram escolhidas a partir do banco de experiências do Programa Gestão Pública e Cidadania, selecionando projetos realizados em cidades com mais de 200 mil habitantes e que já tenham passado por pelo menos três eleições municipais. Os casos estudados foram o Programa de Coleta Seletiva de Lixo de Embu (SP), o Programa de Produção Associada com Garantia de Renda Mínima de Jundiaí (SP) e a Instituição Comunitária de Microcrédito Portosol de Porto Alegre (RS). As análises apontam para a existência de pelo menos quatro fatores que favorecem a continuidade de iniciativas públicas em governos locais. Em primeiro lugar, notou-se a importância de que se desenvolvam ações intencionais para tanto. Além disso, são igualmente importantes fatores técnicos e políticos. Por último, sugere-se que a inserção do projeto ou instituição em coalizões consistentes é benéfico à sua continuidade.

Income and bargaining effects on education and health

In this paper, we examine the impacts of the reform in the rural pension system in Brazil in 1991 on schooling and health indicators. In addition, we use the reform to investigate the validity of the unitary model of household allocation by testing if there were uneven impacts on those indicators depending on the gender of the recipient. The main conclusion of the paper is that the reform had significantly positive effects on the outcomes of interest, especially on those co-residing with a male pensioner, indicating that the unitary model is not a well-specified framework to understand family allocation decisions. The highest impacts were on school attendance for boys, literacy for girls and illness for middle-age people. We explore a collective model as defined by Chiappori (1992) as one possible alternative representation for the decision-making process of the poor rural Brazilian families. In the cooperative Nash equilibrium, the reform effects can be divided into two pieces: a direct income effect and bargaining power effect. The data support the existence of these two different effects

Public investment in basic education and economic growth

The main objective of this paper was to visualize the relation between government spending on basic education and the human capital accumulation process, observing the impacts of this spending on individual investments in higher education, and on economic growth. It is used an overlapping-generations model where the government tax the adult generation and spent it in basic education of the next generations. It was demonstrated that the magnitude of the marginal effect of government spending in basic education on growth crucially depends on public budget constrains. The paper explains why some countries with a lot of public investment in basic education growth at low rates. In that sense if a country has only a lot of public investment in basic education without investment in higher education it may growth at low rates because the taxation can cause distortions in the agents incentives to invest in higher education.

Equity and Efficiency in Education: motivations and targets

The recently released "Educational PAC" attempts to place basic education at the center of the social debate. We have subsidized this debate, offering a diagnosis of how different education levels can impact individuals' lives through broad and easily interpreted indicators. Initially, we analyze how much each educational level reaches the poorest population. For example, how are those in the bottom strata of income distribution benefited by childcare centers, private secondary education, public university or adult education. The next step is to quantify the return of educational actions, such as their effects on employability and an individual's wages, and even health as perceived by the individual, be that individual poor, middle class or elite. The next part of the research presents evidence of how the main characters in education, aka mothers, fathers and children, regard education. The site available with the research presents a broad, user-friendly database, which will allow interested parties to answer their own questions relative to why people do not attend school, the time spent in the educational system and returns to education, which can all be cross-sectioned with a wide array of socio-demographic attributes (gender, income, etc.) and school characteristics (is it public, are school meals offered, etc.) to find answers to: why do young adults of a certain age not attend school? Why do they miss classes? How long is the school day? Aside from the whys and hows of teaching, the research calculates the amount of time spent in school, resulting from a combination between absence rates, evasion raters and length of the school day. The study presents ranks of indicators referring to objective and subjective aspects of education, such as the discussion of the advantages and care in establishing performance based incentives that aim at guiding the states in the race for better educational indicators.

The impact of AIDS on income and human capital

This paper studies the impact of HIV/AIDS on per capita income and education. It explores two channels from HIV/AIDS to income that have not been sufficiently stressed by the literature: the reduction of the incentives to study due to shorter expected longevity and the reduction of productivity of experienced workers. In the model individuals live for three periods, may get infected in the second period and with some probability die of Aids before reaching the third period of their life. Parents care for the welfare of the future generations so that they will maximize lifetime utility of their dynasty. The simulations predict that the most affected countries in Sub-Saharan Africa will be in the future, on average, thirty percent poorer than they would be without AIDS. Schooling will decline in some cases by forty percent. These figures are dramatically reduced with widespread medical treatment, as it increases the survival probability and productivity of infected individuals.

Introducing higher moments in the CAPM: some basic ideas

We show how to include in the CAPM moments of any order, extending the mean-variance or mean-variance-skewness versions available until now. Then, we present a simple way to modify the formulae, in order to avoid the appearance of utility parameters. The results can be easily applied to practical portfolio design, with econometric inference and testing based on generalised method of moments procedures. An empirical application to the Brazilian stock market is discussed.
