Self-interest and incompetence

All social science’s schools have a common assumption: self-interests is the central variable explaining human behavior in society. The author has no contention about that. But says that in contemporary societies a second variable is turning increasingly relevant when one is willing to explain social outcomes: policymakers’ technical and emotional incompetence. Incompetent policymakers, who fail to choose the alternative more consistent with their own objectives, even when interests were neutralized, always existed. But now, that an increasing number of social outcomes are dependent on government policy, competence turned strategic. Besides selfinterest, competence must be assessed when one evaluates social outcomes.

Comparing equilibrium real interest rates : different approaches to measure Brazilian rates

Despite the difficulties involved in the precise determination of equilibrium real interest rates, it seems clear that nominal interest rates has been higher in Brazil than in similar emerging economies. This paper aims to shed light on the possible reasons for this feature of the Brazilian economy. We extend Miranda and Muinhos (2003) one-country study to a sample of 20 countries, using many methods to compare measures of the real interest: (i) extracting equilibrium interest rates from IS curves; (ii) extracting steady state interest rates from marginal product of capital; (iii) capturing relevant variables and the fixed effects having real interest rates as dependent variable in a panel for emerging countries; and (iv) extracting inflation expectation from the spread between fixed rate and inflation-indexed treasure notes.

The trasition from fixed to floating exchange rate regimes: the case of Brazil

This dissertation evaluates macroeconomic management in Brazil from 1994 to the present, with particular focus on exchange rate policy. It points out that while Brazil's Real Plan succeeded in halting the hyperinflation that had reached more than 2000 percent in 1993, it also caused significant real appreciation of the exchange rate situation that was only made worse by the extremely high interest rates and ensuing bout of severe financial crises in the intemational arena. By the end of 1998, the accumulation of internai and externai imbalances led the authorities to drop foreign exchange controls and allow the currency to float. In spite of some initial scepticism, the flexible rate regime cum inflation target proved to work well. Inflation was kept under control; the current account position improved significantly, real interest rates fell and GDP growth resumed. Thus, while great challenges still lie ahead, the recent successes bestow some optimism on the well functioning of this exchange rate regime. The Brazilian case suggests that successful transition from one foreign exchange system to another, particularly during financial crisis, does not depend only on one variable be it fiscal or monetary. In reality, it depends on whole set of co-ordinated policies aimed at resuming price stability with as little exchange rate and output volatility as possible.

An ordering of measures of the welfare cost of inflation in economies with interest-bearing deposits

This paper builds on Lucas (2000) and on Cysne (2003) to derive and order six alternative measures of the welfare costs of inflation (five of which already existing in the literature) for any vector of opportunity costs. The ordering of the functions is carried out for economies with or without interestbearing deposits. We provide examples and closed-form solutions for the log-log money demand both in the unidimensional and in the multidimensional setting (when interest-bearing monies are present). An estimate of the maximum relative error a researcher can incur when using any particular measure is also provided.

Welfare costs of inflation: the case for interest-bearing money and empirical estimates for Brazil

We provide in this paper a closed fonn for the Welfare Cost of Inflation which we prove to be closer than Bailey's expression to the correct solution of the corresponding non-separable differential equation. Next. we extend this approach to ao economy with interest-bearing money, once again presenting a better appoximation than the one given by Bailey's approach. Fmally, empirical estimates for Brazil are presented.

A model to estimate the US term structure of interest rates

The US term structure of interest rates plays a central role in fixed-income analysis. For example, estimating accurately the US term structure is a crucial step for those interested in analyzing Brazilian Brady bonds such as IDUs, DCBs, FLIRBs, EIs, etc. In this work we present a statistical model to estimate the US term structure of interest rates. We address in this report all major issues which drove us in the process of implementing the model developed, concentrating on important practical issues such as computational efficiency, robustness of the final implementation, the statistical properties of the final model, etc. Numerical examples are provided in order to illustrate the use of the model on a daily basis.

Essays on the monetary aspects of the term structure of nominal interest rates

Interest rates are key economic variables to much of finance and macroeconomics, and an enormous amount of work is found in both fields about the topic. Curiously, in spite of their common interest, finance and macro research on the topic have seldom interacted, using different approaches to address its main issues with almost no intersection. Concerned with interest rate contingent claims, finance term structure models relate interest rates to lagged interest rates; concerned with economic relations and macro dynamics, macro models regress a few interest rates on a wide variety of economic variables. If models are true though simplified descriptions of reality, the relevant factors should be captured by both the set of bond yields and that of economic variables. Each approach should be able to address the other field concerns with equal emciency, since the economic variables are revealed by the bond yields and these by the economic variables.

Interesse, ideologia & incompetência: a guerra do Iraque e o segundo consenso de Washington

Este projeto continua a avançar o programa de pesquisa que relaciona desenvolvimento econômico e democracia: pretende-se neste projeto dar um passo adiante e examinar como a democracia, uma vez consolidada como fruto do desenvolvimento capitalista, se torna ela própria um fator de desenvolvimento, particularmente quando ela deixa de ser uma mera democracia de elites para se tornar uma democracia de sociedade civil, na qual o debate público passa a ser um elemento central.

Competição e alavancagem na indústria de aços planos

Pesquisas recentes nos campos das Finanças e de Economia Industrial vêem mostrando que as decisões de financiamento corporativo são interdependentes de decisões relativas ao mercado de produtos. As teorias apresentadas apóiam-se na responsabilidade limitada dos detentores do capital próprio para construir modelos nos quais a dívida é utilizada estrategicamente. Altos níveis de endividamento tendem a favorecer o acirramento da concorrência e a produzir resultados piores do que numa situação de conluio, provocando a adoção de mecanismos de limitação da alavancagem e da concorrência pelo oligopólio. Evidências indicam que firmas alavancadas suavizam a concorrência enquanto firmas menos ou não alavancadas tornam a concorrência mais acirrada ante a presença de um rival mais alavancado. Dados de corte seccional das firmas participantes do mercado brasileiro de aços planos ao carbono foram tratados pelo método econométrico para verificar o comportamento da variável de endividamento tendo como variáveis explicativas de interesse os preços praticados e as quantidades vendidas pelas firmas e, como variáveis de controle, algumas dentre aquelas sugeridas pela teoria da estrutura de capital. Os resultados mostram evidências de que a variável de concorrência "preço" influencia as decisões de estrutura de capital das firmas siderúrgicas produtoras de aços planos e que a correlação com a alavancagem é positiva. No entanto, nenhuma conclusão pôde ser obtida sobre a variável quantidade. Cálculos adicionais produziram resultados que são indicativos de iniciativas de aumento de concorrência pelas firmas mais alavancadas da indústria, como redução de preço, aumento de lucratividade e maior participação de mercado, sugerindo que as circunstâncias de expansão de demanda favorecem a ruptura do conluio.

Does location matter to explain loan interest rates? evidence from Brazilian highly concentrad local markets

O setor bancário brasileiro é altamente concentrado. Embora concentração não signifique necessariamente que o mercado se comporta de forma não competitiva, o grau de competição é freqüentemente questionado no país. Utilizando uma base de dados extensiva e única do mercado de crédito brasileiro, este trabalho procura avaliar muitos dos fatores que contribuem para a variação nas taxas de juros cobradas pelos bancos nos diferentes mercados locais em duas categorias de empréstimos. A concentração não é significante ou mesmo associada a taxas de juros mais baixas, em parte devido ao papel dos bancos públicos. O prêmio de default é positivo e significante, e há alguma evidência de imperfeição de mercado. Neste trabalho, analisamos também o comportamento de precificação dos bancos em diferentes regiões do país, e encontramos que a localização é importante para explicar as taxas de juros dos empréstimos.

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.

Mercado de crédito no Brasil: características e respostas a choques

Verifica-se a existência de forte componente auto-regressivo ao se decompor o impacto dos principais componentes na determinação do volume de crédito no Brasil. Tal fato é indicativo de que a política bancária é muito relevante para determinação do volume de crédito no Brasil. Variáveis controladas pelo governo - como taxa básica de juros e depósitos compulsórios - não mostraram grande impacto no total de crédito. A grande proporção de créditos direcionados na economia brasileira, com a contrapartida de ser positiva na formulação de políticas públicas, traz conseqüências negativas como: (i) maior taxa de juros nos empréstimos livre; (ii) dificuldade de construir mercado de empréstimos para prazos mais longos, especialmente para empresas; e (iii) maior inércia à política monetária.
