This paper presents new evidence on the role of cognitive skills in promoting economic growth rate, using a within country dataset (Brazilian municipalities’ dataset) and nonparametric kernel regression estimation with mixed data.

This article generalizes the conditional stochastic kernel developed by Quah (1997, 1998) for multiple and more general conditioning schemes using nonparametric conditional density estimation. We utilize this methodology to analyze conditional convergence in income for Brazilian municipalities...

This article analyses the evolution of relative per capita income distribution of Brazilian municipalities over the period 1970-1996. Analyses are based on non-parametric methodologies and do not assume probability distributions or functional forms for the data. Two convergence tests have been...

In this article, we test the hypothesis of contagion amongst sectors within the United States' economy during the subprime crisis. The econometric methodology applied here is based on the dynamic conditional correlation model proposed by Engle (2002). Further, we applied several Lagrange...

This article investigates the existence of contagion between countries on the basis of an analysis of returns for stock indices over the period 1994 to 2003. The econometrics methodology used is that of multivariate Generalized Autoregressive Conditional Heteroscedasticity (GARCH) family...
