O impacto da Lei de Responsabilidade Fiscal no desempenho financeiro e na execução orçamentária dos municípios no Rio Grande do Sul de 1997 a 2004

Sandra Regina Toledo Santos; Tiago Wickstrom Alves

This paper analyses the performance of Rio Grande do Sul cities based on economic and financial indicators from 1997 to 2005 aiming at assessing the impact of the so-called Fiscal Responsibility Law (FRL) on financial performance and budget execution. Nine indicators were employed and through a regression using panel data it was estimated the changes on those indicators after the introduction of the FRL. The results show that seven out of the nine indicators had a better performance due to the FRL, as expected by the theory.

External financial liberalization and growth in emerging countries: a panel data estimation using a new index (1990-2004)

Cesar Rodrigues van der Laan; André Moreira Cunha; Tiago Wickstrom Alves

The 2008 financial crisis and its economic downturn have reignited the fierce debate about the financial liberalization and its implications on economic growth, especially in the realm of the developing countries. In this paper, we focus on this line of research, contributing in two main ways. First, we present an alternative method to measure financial liberalization, based on the same International Monetary Fund (IMF) annual reports most studies currently use as source of data. Second, we use panel data for a group of relevant emerging countries in Latin America and East Asia, including the new proxy in an attempt to test its effects on economic growth during the recent period (1990-2004). The more reliable index has not changed the main consensus on the subject, though, as results are in accordance with the prevalent thesis on the literature, that is, the link between financial liberalization and economic growth might not be as strong as may be supposed in theory. This means the other basic theoretical determinants must instead be observed to spur growth, while countries should observe the Keynesian agenda of stabilizing international finance through the introduction of limits to the free mobility of capital flows, as IMF economists have recently supported.

Estudo da economia de escala do setor de telecomunicações móveis do Brasil pós-privatizações

Maria Ivanice Vendruscolo; Tiago Wickstrom Alves

RESUMO O setor de telecomunicacoes passou por signifi cativas transformacoes estruturais, inovacoes tecnologicas e mudancas nos processos regulatorios nas ultimas decadas, em nivel mundial. A telefonia movel brasileira seguiu a mesma tendencia, desenvolvendo uma complexa estrutura oligopolista apos a quebra do monopolio estatal. Inicialmente, com a abertura do mercado, foi adotada uma estrutura na qual a competicao se dava entre operadoras de Banda A e B. Num segundo momento, com o cumprimento das metas de universalizacao, previstas pelo novo modelo de telecomunicacoes brasileiro, a concorrencia entre as operadoras foi intensifi cada, com a entrada das operadoras de Banda D e E. Dadas as mudancas ocorridas na estrutura de mercado do setor de telefonia brasileiro, no periodo pos-privatizacoes, este estudo teve por objetivo verifi car se as operadoras de telefonia movel brasileiras estavam usufruindo economias de escala por meio da analise da funcao de custo polinomial e das curvas de custos. A pesquisa foi de natureza aplicada do tipo documental, utilizando o metodo estatistico de minimos quadrados com um modelo para dados em painel. Os resultados estimados da funcao de custos para o setor revelaram que a producao com base no numero de clientes apresentou retornos crescentes e decrescentes de producao, evidenciando a existencia de economias de escala no setor. Entretanto, o setor encontrava-se com um numero excessivo de empresas, dada a demanda do mercado para que as empresas de telefonia movel brasileiras pudessem usufruir os beneficios dos ganhos de escala. Palavras-chave: Economia de escala. Funcao de custos. Telecomunicacoes.

Fatores determinantes da evasão universitária: uma análise com alunos da UNISINOS

Vanessa Viégas Alves Furtado; Tiago Wickstrom Alves

O presente trabalho tem como objetivo realizar uma analise dos fatores determinantes da evasao universitaria naUniversidade do Vale do Rio dos Sinos (UNISINOS). O estudo foi conduzido com base em uma amostra representativade alunos da UNISINOS, ingressantes no periodo de 2005 a 2008, tendo avaliado, por meio de regressao Logit, a relacaoentre variaveis socioeconomicas e evasao discente. Pelos resultados da pesquisa concluiu-se que algumas variaveispesquisadas possuiam relacao crescente a evasao, como, por exemplo, a variavel disciplinas canceladas, em que umnumero maior de cancelamentos resultou em uma probabilidade mais elevada de evasao por parte dos alunos. Outrasvariaveis possuiam relacao inversa a esse fenomeno, como a variavel disciplinas cursadas, na qual um numero maior dedisciplinas cursadas por semestre reduzia as chances de o estudante evadir.

DEMANDA E OFERTA ENERGÉTICA: UMA PERSPECTIVA MUNDIAL E NACIONAL PARA O ETANOL

Fernanda Schutz; Angélica Massuquetti; Tiago Wickstrom Alves

This paper estimates the bilateral trade flows between the BRICs – Brazil, Russia, India and China – in the next decades. This study employs a gravity model based on a sample of 57 countries. Trade flows and a variety of other data were collected from 2000 to 2007 to enable the estimation of gravity equations that explain the international trade in this period. By using two different estimation methods – OLS and Tobit – a wide set of parameters was generated, with the aim to choose the most adequate equations for the estimations wanted. Finally, these two best parameter sets were arranged and applied on gravity equations, combined with the Goldman Sachs predictions, in order to obtain future estimations of bilateral trade flows between them in three time-scenarios: short term (2010), midterm (2020) and long term (2030). The results show that the ‘intra-BRICs’ trade flows will grow even more than the GDP of these countries, meaning an increase in the interdependence among these economies, contributing to maintain their economic growth.

CAPITAL HUMANO E O DESEMPENHO ECONÔMICO-FINANCEIRO DE EMPRESAS BRASILEIRAS DO SETOR ELÉTRICO

Jonas Ismael da Silva; Clea Beatriz Macagnan; Tiago Wickstrom Alves; Francisco Zanini

This paper characterize as empiric study about intangible resources, based in the theory Resource Based View of the Firm (RBV) with the objective of analyzing if relationship exists among the investment in human capital and the economical-financial development of the companies of the electric section, with striped actions in the Brazilian stock exchange. The universe of 26 Brazilian companies of the electric industry, in the period from 2001 to 2008, a sample of 184 representative elements was analyzed. The methodology was of OSM, with data in panel. For representation of the explanatory variable on intangible resources was used Value Added Intellectual Coefficient - VAICTM coefficient, proposed by Pulic (2000). The obtained results are statistically significant, the one that makes possible infer that the companies that invested more in human capital those that obtained better economical-financial acting were. This study, considering the electric segment, it supplies empiric evidences that the companies that invest in human capital and financial capital can obtain better economical-financial acting.

Análise da capacidade explicativa do investimento pelo q de Tobin em empresas brasileiras de capital aberto

Edson Luis Kammler; Tiago Wickstrom Alves

The aim of this work is to test the explanatory capacity of investments in publicly-quoted Brazilian companies using Tobin’s “q” theory. The study was carried out by means of panel data analysis, using data taken from the balance sheet and share prices on the stock exchange. The greatest difficulty with Tobin’s “q” theory is calculating the replacement cost of capital, although there are approximations that can facilitate the calculation. In this work we adopted the models proposed by Chung and Pruitt (1994) and by Lee and Tompkins (1999), because they were considered to be a simplified approximation of “q”. For these particular analyses we worked with the years 2002 to 2008, using the “q” variable in the same year as the investment, with a one period lag and squared. This work is innovative in that it provides evidence of the possibility of measuring the replacement cost of capital and, therefore, testing Tobin’s “q” theory within the Brazilian context. We concluded that it is possible to explain variations in investments by means of Tobin’s “q” theory, thereby obtaining more significant results than other analyses that used other approximations for Tobin’s “q”.

Tiago Wickstrom Alves

This article analyzes, through the structural-differential method, the creation of jobs in Brazil, having as comparative base the Brazilian Federated States, from 1970 to 1980. The data were obtained of the Population Censuses published by the IBGE. Through this study the disparity of the capacity of creating States jobs could be perceived. Additionally, Ii is possible to realize that this disparity would be responsible for the industrial concentration in the following decades. Key words: Employment; structural-differential method; economic growth

Dynamics of housing finances in the towns of Rio Grande do Sul: an evaluation of the program "My House, My Life"

Cátia Fernanda da Silva; Tiago Wickstrom Alves

O presente trabalho tem como objetivo avaliar a dinâmica dos financiamentos habitacionais nos municipios do Rio Grande do Sul no periodo compreendido entre 2006 e 2010. Para isso, utiliza-se informacoes obtidas junto a Caixa Economica Federal, instituicao responsavel por 73% do total de financiamentos imobiliarios realizados no Brasil (FINANCIAMENTO, 2010). Para esta analise utiliza-se de tres tipos de avaliacoes: metodo estrutural-diferencial, tecnicas de krigagem e regressao espacial. Como resultados obtidos atraves do estudo, pode-se inferir que houve um maior dinamismo no periodo considerado nas faixas de maior valor de imovel. Alem disso, houve um processo de crescimento mais intenso nas zonas de depressao. As curvas de nivel, baseadas no valor do efeito liquido do metodo estrutural-diferencial, permitem constatar que houve um movimento de dispersao do volume de financiamento para essas areas. Ainda, os maiores volumes de financiamento sao concedidos nos municipios que possuem um maior PIB per capita, um maior IDESE e menor taxa de urbanizacao. Municipios com pequenas extensoes territoriais e grande concentracao populacional tambem apresentam um volume maior de financiamentos. As variaveis utilizadas no modelo de regressao espacial foram significativas, explicando 95% das alteracoes ocorridas com a variavel dependente. Destaque para a variavel deficit habitacional, que nao foi significante em nenhum dos anos analisados.
