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.

Impacto sobre a renda per capita de longo prazo de um sistema de aposentadoria de repartição simples

Este trabalho constrói um modelo de gerações sobrepostas em tempo contínuo de acumulação de capital. Os indivíduos passam por dois períodos de vida distintos. No primeiro, que transcorre entre o nascimento até a idade de T anos, os indivíduos ofertam trabalho inelasticamente, consomem e acumulam capital de forma ótima e se defrontam com uma probabilidade de morte nula. No segundo aposentam-se e passam a ter uma probabilidade de morte positiva, auferindo renda do patrimõnio acumulado ej ou recebendo transferências financiadas com imposto distorcido sobre a renda. Neste caso há um sistema de previdência de repartição simples. A partir da agregação das escolhas individuais, encontra-se uma equação para o capital de estado estacionário no sistema fundado e no sistema de repartição simples. Pode-se então calcular a renda de estado estacionário em cada um dos sistemas e a sensibilidade do diferencial de renda com ralação a diversos parâmetros.

Avaliação de políticas públicas: estudo do comportamento de indicadores relacionados com a saúde em municípios do estado de Pernambuco após a emenda Constitucional Nº 29

The Brazilian Public Health System (Sistema Único de Saúde - SUS), defined by the Constitution of 1988, is almost 20 years old and is a landmark for health public policies. In these 20 years, the law was altered several times with the objective of prioritizing the investment of public money in such a needy area as health. Among these changes, it is important to single out the Constitutional Amendment number 29, issued on 13th September 2000, which determined the minimum investment in health. According to this amendment, as from the year 2000, the municipalities should invest in health services a minimum of 7% of the revenue from taxes and transferences from the Federal and State governments. This value was to rise gradually to 15% by 2004. Since every public policy should be systematically evaluated and considering the assumption that, according to the incrementalist theory, more money invested in health would tend to solve the crisis in the health system, this dissertation consists of a study of a set of health indicators in some municipalities of the State of Pernambuco after the Amendment 29. The evaluation period spanned 4 years, from 2002 to 2005 and the area chosen for the study was located in southern agreste region of the state. Ten health indicators were selected, all of which included in the Administrative Rule no 493, of the Health Ministry. It was found that in the chosen period the average investment in health was greater than 15% of the municipalities¿ revenue since 2002. However, the value of the investment per capita, considering the municipality's share of it, which was half of the total investment, decreased from 2002 to 2004 and increased in 2005. It was also found that the municipalities with the lowest per capita income were the ones with the highest investment per capita in health. As regards children mortality in the region, it was on average 33 for every 1000 children born, which is classified as ¿medium¿ according to the above mentioned Administrative Rule no 493. No statistically significative correlation was found between the amount of money invested in health and children mortality.

Flypaper effect revisited : evidence for tax collection efficiency in Brazilian municipalities

This paper has two purposes. First, to construct efficiency scores in tax collection for Brazilian municipalities in 2004, taking into consideration two outputs: amount of per capita local tax collected -tax revenue- and the size of local informal economy- tax base. This methodology eliminates the price- effect of tax collection. Second, using the rules established on the Brazilian Constitution in 1988 to transfer unconditional funds among municipalities as instrument, to estimate the relationship between intergovernmental transfers and efficiency in tax collection. We conclude that transfers affect negatively the efficiency in tax collection, leading to a reinterpretation of the flypaper effect.

Empirical evidence on real convergence across brazilian states

This paper examines the real convergence hypothesis across Brazilian states. In order to test for the existence of income convergence the or- der of integration of real Gross State Product (GSP) per capita series is examined as well as their di¤erences with respect to the São Paulo state which is used as a benchmark state. Both parametric and semiparametric methods are used and the results show that convergence is achieved in the cases of Alagoas, Amazonas, Bahia, Goiás, Mato Grosso, Minas Gerais, Pernambuco, Piauí, Rio Grande do Sul, Rio de Janeiro and Santa Cata- rina and convergence is weakly achieved in the cases of Ceará, Maranhao, Pará, Paraná and Sergipe .The states of Espírito Santo, Paraíba and Rio Grande do Norte show no convergence. O artigo examina a hipótese de convergência real entre os estados brasileiros. Para testar a existência ou não da convergência da renda a ordem da integração da série do produto real bruto do estado per capita é examinada assim como suas diferenças com respeito ao estado de São Paulo que é usado como base. Foram utilizados métodos paramétricos e semiparametric e os resultados mostram que ocorre convergência nos estados: Alagoas, Amazonas, Baía, Goiás, Mato Grosso, Minas Gerais, Pernambuco, Piauí, Rio Grande do Sul, Rio de Janeiro e Santa Catarina e ocorre convergência fraca nos estados: Ceará, de Maranhão, Pará, Paraná e Sergipe.

Crescimento e convergência de renda entre os estados brasileiros

O objetivo principal da tese medir a velocidade de convergência entre renda per-capita dos estados brasileiros. Para atingir este intento tese foi dividida em dois capítulos, um para situar discussão realizada na literatura relacionada ao crescimento econômico, outro para realizar tarefa que se propunha trabalho. No primeiro capitulo é feita uma revisão de todos os principais modelos de crescimento desenvolvidos partir da tradição neoclássica de funções de produção com rendimentos decrescentes para os fatores de produção. Nesta revisão são destacados duas importantes conclusões destes modelos, a existência de convergência entre renda per-capita de todos os países ao esgotamento do crescimento. Logo em seguida são apresentadas tentativas de construção de modelos que não levem estes resultados. Por fim, são feitas considerações respeito de convergência entre renda per-capita de países com características semelhantes, culminando no tema de convergência entre estados de um mesmo pais. No segundo capitulo principal objetivo verificar existência de um processo de convergência entre renda per-capita para caso dos estados brasileiros e, uma vez verificada existência deste processo, calcular velocidade de convergência. Para alcançar este objetivo utiliza-se da metodologia usada por Barro Sala-i-Martin Convergence, Journal of Political Economy, 1992) para os estados americanos. No desenvolver do trabalho também foi feita uma tentativa para estimar os PIB's dos estados brasileiros para ano de 1990. conclusão obtida de que os estados brasileiros estão convergindo em termos de renda per-capita, porem uma velocidade menor que a dos estados americanos.

Determinantes do crescimento: uma comparação das regressões em sistemas de equações cross-section com regressões em painel

Essa tese se propõe fazer uma comparação entre duas técnicas alternativas para estudo de impactos marginais de variáveis sócio-econômicas sobre as taxas de crescimento per-capita de grupos de países durante período de 1965 1985: regressão em sistemas de equações com dados em seções transversais, usada por Barro Sala-i-Martin (1995), entre outros, e a regressão em painel com coeficientes individuais. Tentaremos mostrar que os resultados associados certas variáveis são bastante diferentes procuraremos entender algumas causas dessas diferenças. Além disso, estaremos preocupados em avaliar como os resultados são afetados ao alterarmos conjunto de países estudado, em particular quando tomamos grupos de países com uma série de características semelhantes.

The welfare cost of macroeconomic uncertainty in the post-war period

Lucas (1987) has shown the surprising result that the welfare cost of business cycles is quite small. Using standard assumptions on preferences and a fully-áedged econometric model we computed the welfare costs of macroeconomic uncertainty for the post-WWII era using the multivariate Beveridge-Nelson decomposition for trends and cycles, which considers not only business-cycle uncertainty but also uncertainty from the stochastic trend in consumption. The post-WWII period is relatively quiet, with the welfare costs of uncertainty being about 0:9% of per-capita consumption. Although changing the decomposition method changed substantially initial results, the welfare cost of uncertainty is qualitatively small in the post-WWII era - about $175.00 a year per-capita in the U.S. We also computed the marginal welfare cost of macroeconomic uncertainty using this same technique. It is about twice as large as the welfare cost ñ$350.00 a year per-capita.

The implications of embodiment and Putty-Clay to economic development

In this paper we construct and analyze a growth model with the following three ingredients. (i) Technological progress is embodied. (ii) The production function of a firm is such that the firm makes both technology upgrade as well as capital and labor decisions. (iii) The firm’s production technology is putty-clay. We assume that there are disincentives to the accumulation of capital, resulting in a divergence between the social and the private cost of investment. We solve a single firm’s problem in this environment. Then we determine general equilibrium prices of capital goods of different vintages. Using these prices we aggregate firms’ decisions and construct the theoretical analogues of National Income statistics. This generates a relationship between disincentives and per capita incomes. We analyze this relationship and show the quantitative and qualitative roles of embodiment and putty-clay. We also show how the model is taken to data, quantified and used to determine to what extent income gaps across countries can be attributed to disincentives.

Integração, crescimento e bem-estar

Neste artigo desenvolve-se um modelo de crescimento econômico endógeno para o caso de duas economias integradas levando-se em conta a presença de custos de transporte na forma de iceberg costs. A presença de tais custos juntamente com a existência de ganhos de escala terá um efeito negativo sobre a taxa de crescimento dos países integrados e exercerá um importante efeito sobre a localização da produção de insumos intermediários. Demonstra-se, no entanto, que um processo de integração com custos de transporte ainda leva a um aumento da taxa de crescimento de estado estacionário devido ao aumento do mercado consumidor de insumos. O ganho de bem-estar decorrente da integração dependerá das dotações de cada país, na medida em que o nível de consumo per capita após a integração depende destas dotações. Adicionalmente, apresenta-se uma simulação de ganhos em termos de taxa de crescimento do PNB e de bem-estar para uma integração econômica entre Brasil e Argentina.

The effects of longevity and distortions on education and retirement

This article studies the impact of longevity and taxation on life-cycle decisions and long-run income. Individuals allocate optimally their total lifetime between education, working and retirement. They also decide at each moment how much to save or consume out of their income, and after entering the labor market how to divide their time between labor and leisure. The model incorporates experience-earnings profiles and the return-to-education function that follows evidence from the labor literature. In this setup, increases in longevity raises the investment in education - time in school - and retirement. The model is calibrated to the U.S. and is able to reproduce observed schooling levels and the increase in retirement, as the evidence shows. Simulations show that a country equal to the U.S. but with 20% smaller longevity will be 25% poorer. In this economy, labor taxes have a strong impact on the per capita income, as it decreases labor effort, time at school and retirement age, in addition to the general equilibrium impact on physical capital. We conclude that life-cycle effects are relevant in analyzing the aggregate outcome of taxation.
