Brazilian regional development distribution, evidences for socio-economic policy

As to many Latin american countries, the impacts of the recent economic globalization on the Brazilian economy have revealed a diversified tendency in spatial development when regional economic indicators are observed. This is due to the specificities or each region, as regard their sector structure, the availability of human resources and the degree of technological innovation undertaken by local enterprises. From a situation of regional inequalities observed in lhe socio-economic levels of development at the beginning of the eighties the dynamics of the Brazilian regional evolution has presented different speeds and intensities in the several spaees. This paper aims to evaluate the dynamics of Brazilian regional development during the 1985-95 period and the impacts over the working population and regional disparities in order to offer some elements to assist social and economic policy. For this purpose Dispersion Quotients and Dispersion lntensity Coefficients were calculated based on two variables, the Regional Gross Domestic Product anel the Working Population. The results of the analysis confirm the existence of considerable regional disparities and it was observed that thc sector and regional redistribution of the GDP indicate that in a general way, no remarkable changes occurred in the regional development in the period. The results show that although the economic policies did stimulate a global convergence process of the per capita product among regions, those policies did not attenuate economic dynamism concentration to the desired extent.

Productive restructuring: effects on Brazilian regional development distribution

This paper aims to evaluate the dynamics of Brazilian regional development during the 1985-95 period. First, regional inequalities indexes were calculated for the whole country’s economy based on the per capita regional income (Williamson Inequality Index), in order to test the convergence or divergence. After this, the analysis aimed to verify the sector and regional dynamics in a more detailed exam, and for this purpose Dispersion Quotients and Dispersion Intensity Coefficients were calculated based on two variables, the Regional Gross Domestic Product and the Working Population. The results of the analysis confirm the existence of considerable regional disparities and it was verified that the sector and regional redistribution of the GDP indicate that, in a general way, no remarkable changes occurred in the regional productive structures in the period. It is also inferred that the economic policy at that period, in spite of resulting in a global regional convergence process of the per capita product, did not avoid the continuation of the concentration of greater economic dynamism in the most advanced regions, nor did it diminish in any considerable way the difference in the degree of development of the Northeast region.

O regime geral de previdência social: diagnósticos estruturais críticos e proposta de reformas

Since the last decade of the past century and further, there have been increased, polemic discussions in Brazil that are also occurring simultaneously in the rest of the world: the sustainability of public pension systems. The Brazilian system, which is denominated as the General Regimen of Social Welfare and was established in a distribution regimen, is becoming a growing source of expenditures for the Federal Government and is contributing to the increasing of its fiscal deficit. This situation started to decline after the promulgation of the Federal Constitution in 1988, in which actions had been established reflecting the feeling of ¿social debt¿ existing in the country by that time after years of economic growth without yield redistribution. Thus, benevolent rules had been instituted that provided an assistancialist character to the program, making it unsustainable when it is seen by the internationally accepted premise of the pension system as social insurance with perpetual duration. In consequence, there was an explosive growth of the financial needs of the system reaching the equivalent of 1.63% of the Gross Domestic Product in 2005. In this sense, many arguments in favor of revision and reforms in the current model had solidified, resulting, in 1998, in some changes in the contribution rules of the diverse sectors of society, as well as in the concession of benefit rules. However, such changes had not obtained significant effects since the main source of the imbalance, which is essentially structural, was not attacked. Therefore, this research seeks to diagnose some of the most structural points in the current public pension system in Brazil and evaluate what can be done in terms of reforms to turn the program into balance again and in restore harmony with its conceptual objectives.

Internet share of advertising expenditure : growth drivers and inhibitors in the brazilian market

Os investimentos com publicidade na Internet como uma percentagem das despesas totais de publicidade variam significativamente de um país para outro. O número é tão baixo quanto 4,7% no mercado brasileiro e tão alto como 28,5% no mercado britânico (ZenithOptimedia, 2011b). Algumas razões explicam tal disparidade. No nível macro, a participação dos gastos com publicidade na Internet está fortemente ligada a variáveis como o produto interno bruto per capita e à penetração da Internet na população. No nível micro, uma pesquisa qualitativa foi feita para identificar os fatores que contribuem e inibem o crescimento da participação da publicidade online no mercado brasileiro. A vasta lista de inibidores parece ter profundo impacto sobre como os profissionais de mercado tomar decisões de alocação de investimento em publicidade por tipo de mídia. Devido à legislação, à auto-regulamentação e às dinâmicas da indústria, grande parte da tomada de decisão é realizada por agências de publicidade. Estas parecem ter fortes incentivos econômicos para selecionar outros tipos de mídia e não a Internet ao definir planos de mídia. Ao mesmo tempo, a legislação e a auto-regulamentação fornecem desincentivos para corretores de mídia a operar no mercado local. A falta de profissionais qualificados e a padronização limitada também desempenham papéis importante para inibir uma maior participação da Internet nos gastos com publicidade no Brasil. A convergência dos resultados quantitativos com os qualitativos indica possíveis motivos pelos quais a participação da publicidade online no Brasil é tão baixa. Em primeiro lugar, a participação é explicada pelo estágio de desenvolvimento dos países. Quanto mais rico e mais desenvolvido um país, maior a proporção de gastos com publicidade online tende a ser. Em segundo lugar, o estágio econômico emergente do Brasil potencialmente dá espaço para o aumento do ineficiências do mercado, tais como programas de descontos oferecidos de forma desproporcional para os principais decisores de alocação de investimentos de mídia. Este fato aparentemente produz um feedback negativo, contribuindo para manter a baixa participação da publicidade online no total dos investimentos publicitários.

Public debt and the limits of fiscal policy to increase economic growth

Research that seeks to estimate the effects of fiscal policies on economic growth has ignored the role of public debt in this relationship. This study proposes a theoretical model of endogenous growth, which demonstrates that the level of the public debt-to-gross domestic product (GDP) ratio should negatively impact the effect of fiscal policy on growth. This occurs because government indebtedness extracts part of the savings of the young to pay interest on the debts of the older generation, who are no longer saving. Therefore, the payment of debt interest assumes an allocation exchange role between generations that is similar to a pay-as-you-go pension system, which results in changes in the savings rate of the economy. The major conclusions of the theoretical model were tested using an econometric model to provide evidence for the validity of this conclusion. Our empirical analysis controls for timeinvariant, country-specific heterogeneity in the growth rates. We also address endogeneity issues and allow for heterogeneity across countries in the model parameters and for cross-sectional dependence.

Modelagem do produto interno bruto brasileiro utilizando modelos não lineares

O trabalho tem como objetivo aplicar uma modelagem não linear ao Produto Interno Bruto brasileiro. Para tanto foi testada a existência de não linearidade do processo gerador dos dados com a metodologia sugerida por Castle e Henry (2010). O teste consiste em verificar a persistência dos regressores não lineares no modelo linear irrestrito. A seguir a série é modelada a partir do modelo autoregressivo com limiar utilizando a abordagem geral para específico na seleção do modelo. O algoritmo Autometrics é utilizado para escolha do modelo não linear. Os resultados encontrados indicam que o Produto Interno Bruto do Brasil é melhor explicado por um modelo não linear com três mudanças de regime, que ocorrem no inicio dos anos 90, que, de fato, foi um período bastante volátil. Através da modelagem não linear existe o potencial para datação de ciclos, no entanto os resultados encontrados não foram suficientes para tal análise.

O mercado acionário brasileiro e a macroeconomia: um estudo sobre o impacto de indicadores macroeconômicos e da política monetária sobre diversos setores e índices de ações

Este trabalho consiste no estudo do tipo de correlação e previsibilidade existentes entre a bolsa brasileira, representada pelos índices Ibovespa e SmallCaps, e indicadores macroeconômicos, como produção industrial, inflação e Produto Interno Bruto. No processo, o mercado acionário é dividido setorialmente. Tal divisão tenta reduzir os riscos não sistêmicos através da diversificação de ações e se utiliza de um critério de liquidez pré-estabelecido. A parte final do trabalho estuda a relação desses setores com indicadores mais específicos da economia brasileira como crédito, inadimplência, vendas no varejo, produção e licenciamento de veículos.

Essays on economic growth

A fundamental question in development economics is why some economies are rich and others poor. To illustrate the income per capita gap across economies consider that the average gross domestic product (GDP) per capita of the richest 10 percent of economies in the year 2010 was a factor of 40-fold that of the poorest 10 percent of economies. In other words, the average person in a rich economy produces in just over 9 days what the average person in a poor economy produces in an entire year. What are the factors that can explain this difference in standard of living across the world today? With this in view, this dissertation is a conjunction of three essays on the economic growth field which we seek a possible responses to this question. The first essay investigates the existence of resource misallocation in the Brazilian manufacturing sector and measures possible distortions in it. Using a similar method of measurement to the one developed by Hsieh and Klenow (2009) and firm-level data for 1996-2011 we find evidence of misallocation in the manufacturing sector during the observed period. Moreover, our results show that misallocation has been growing since 2005, and it presents a non-smooth dynamic. Significantly, we find that the Brazilian manufacturing sector operates at about 50% of its efficient product. With this, if capital and labor were optimally reallocated between firms and sectors we would obtain an aggregate output growth of approximately 110-180% depending on the mode in which the capital share is measured. We also find that the economic crisis did not have a substantial effect on the total productivity factor or on the sector's misallocation. However, small firms in particular seem to be strongly affected in a global crisis. Furthermore, the effects described would be attenuated if we consider linkages and complementarity effects among sectors. Despite Brazil's well-known high tax burden, there is not evidence that this is the main source of resource misallocation. Moreover, there is a distinct pattern of structural change between the manufacturing sectors in industrialized countries and those in developing countries. Therefore, the second essay demonstrate that this pattern differs because there are some factors that distort the relative prices and also affect the output productivity. For this, we present a multi-sector model of economic growth, where distortions affect the relative prices and the allocation of inputs. This phenomenon imply that change of the production structure or perpetuation of the harmful structures to the growth rate of aggregate output. We also demonstrate that in an environment with majority decision, this distortion can be enhanced and depends on the initial distribution of firms. Furthermore, distortions in relative prices would lead to increases in the degree of misallocation of resources, and that imply that there are distinct patterns of structural changes between economies. Finally, the calibrated results of the framework developed here converge with the structural change observed in the firm-level data of the Brazilian manufacturing sector. Thereafter, using a cross-industry cross-country approach, the third essay investigates the existence of an optimal level of competition to enhance economic growth. With that in mind, we try to show that this optimal level is different from industrialized and under development economies due to the technology frontier distance, the terms of trade, and each economy's idiosyncratic characteristics. Therefore, the difference in competition industry-country level is a channel to explain the output for worker gap between countries. The theoretical and empirical results imply the existence of an inverted-U relationship between competition and growth: starting for an initially low level of competition, higher competition stimulates innovation and output growth; starting from a high initial level of competition, higher competition has a negative effect on innovation and output growth. Given on average industries in industrialized economies present higher competition level. With that if we control for the terms of trade and the industry-country fixed effect, if the industries of the developing economy operated under the same competition levels as of the industrialized ones, there is a potential increase of output of 0.2-1.0% per year. This effect on the output growth rate depends on the competition measurement used.

Efeitos de variáveis macroeconômicas no nível de liquidez de empresas brasileiras

Com a evolução dos mercados e a possibilidade de acesso a informações em tempo real, as empresas se encontram bastante expostas a variações em sua liquidez. Surge então uma necessidade de se estudar o que afeta sua operação e de que forma são afetadas por choques na economia. Este trabalho tem como objetivo investigar como variações de indicadores macroeconômicos, como por exemplo, mudanças na taxa de câmbio, no PIB, na inflação e na taxa de juros impactam no nível de liquidez corrente das empresas. Foram selecionados dados de empresas brasileiras ativas para o período de 2003 até 2011 (dados trimestrais), com ações negociadas na BM&FBovespa e não pertencentes ao setor financeiro e de seguros. Os resultados sugerem que o nível de liquidez das empresas é afetado por algumas variações de indicadores macroeconômicos. Verificou-se que variáveis como PIB, IBOVESPA e taxa de juros se relacionam positivamente com o índice de liquidez corrente. Já as variáveis câmbio e inflação se relacionam negativamente.

Essays in macroeconometrics

The knowledge of the current state of the economy is crucial for policy makers, economists and analysts. However, a key economic variable, the gross domestic product (GDP), are typically colected on a quartely basis and released with substancial delays by the national statistical agencies. The first aim of this paper is to use a dynamic factor model to forecast the current russian GDP, using a set of timely monthly information. This approach can cope with the typical data flow problems of non-synchronous releases, mixed frequency and the curse of dimensionality. Given that Russian economy is largely dependent on the commodity market, our second motivation relates to study the effects of innovations in the russian macroeconomic fundamentals on commodity price predictability. We identify these innovations through a news index which summarizes deviations of offical data releases from the expectations generated by the DFM and perform a forecasting exercise comparing the performance of different models.

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.
