The aim of this paper is to present a systematic and detailed account regarding the behavior of Spanish regional unemployment rates throughout the last two decades of the 20th century. In a first approach we use descriptive techniques that allow to confirm the existence, and especially the...

This paper is concerned with parameter estimation and inference in a cointegrating regression, where as usual endogenous regressors as well as serially correlated errors are considered. We propose a simple, new estimation method based on an augmented partial sum (integration) transformation of...

This paper develops an asymptotic theory for test statistics in linear panel models that are robust to heteroskedasticity, autocorrelation and/or spatial correlation. Two classes of standard errors are analyzed. Both are based on nonparametric heteroskedasticity autocorrelation (HAC) covariance...

We consider the problem of estimating the variance of the partial sums of a stationary time series that has either long memory, short memory, negative/intermediate memory, or is the first-difference of such a process. The rate of growth of this variance depends crucially on the type of memory,...

In this paper, we investigate the asymptotic properties of nonparametric Bayesian mixtures of Betas for estimating a smooth density on [0, 1]. We consider a parametrization of Beta distributions in terms of mean and scale parameters and construct a mixture of these Betas in the mean parameter,...

Este trabajo evalúa la hipótesis de convergencia en indicadores sociales en la Costa Caribe colombiana durante el período 1985-2005 y contrasta los resultados obtenidos con los patrones de convergencia en el resto del país. A este efecto, se usa el índice de Necesidades Básicas...
