Este artigo estuda a persistência das flutuações do crescimento econômico brasileiro com dados anuais de 1900 a 2008. Para a análise das séries são usados modelos ARFIMA e testes de raiz unitária com quebras estruturais. Os resultados indicam que ambos PIB e PIB per capita brasileiros...

O presente artigo estima equações de oferta e demanda por exportações de automóveis brasileiros, entre 1992Q1 e 2006Q4, usando o mecanismo de correção de erro com parâmetros fixos e variáveis no formato espaço-estado. Pelos resultados das elasticidades de curto e longo prazo, pode-se...

This study approaches the survival ability of firms in the North region of Portugal from 1985 to 2007, allowing regional and national comparisons through the application of non-parametric and semi-parametric methods. This analysis is based on the creation of a specific entrepreneurship database,...

This study suggests an alternative approach, nested in exogeneity tests, to verify Ricardian Equivalence. The intuitive appeal and the sophisticated statistical method are the advantage of this new procedure. Furthermore, two others contributions are made: a) an explanation to the failure of...

This paper shows new econometric estimates for the Brazilian function of aggregate imports. Besides the basic relation, which includes income and relative price and identifies a demand equation (canonic model), we explore the pronounced co-movements between total imports, household consumption...

This paper estimates the Brazilian NAILO (Nonaccelerating Inflation Level of Output), obtains (Bayesian) probability bands for the Nailo and for its growth rate, and investigates the relationship between deviations of output with respect to the Nailo and the acceleration of inflation. As...
