In this paper we introduce two general non-parametric first-order stationary time-series models for which marginal (invariant) and transition distributions are expressed as infinite-dimensional mixtures. That feature makes them the first Bayesian stationary fully non-parametric models developed...

Spanish Abstract: La relación existente entre el riego y la rentabilidad de un activo financiero es una preocupación constante del inversionista a la hora de conformar su portafolio de inversión. La principal meta en la construcción del portafolio consiste en distribuir óptimamente la...

Two possibilities of analysis of economic cycles are studied in this document. Firstly, filter-design approaches consisting of the extraction of the information content of certain signals between two specific frequencies, as well as below or above certain frequencies. Secondly, model-based...

En este documento se establecen algunos hechos estilizados acerca del comportamiento de los precios regulados en Colombia. Se analiza el grado de rigidez de los precios en diferentes categorías de productos, con un énfasis particular en los precios regulados. En el documento se establece que...

Este documento se concentra en el crecimiento del gasto público, definido aquí como la suma entre consumo público e inversión pública, como un determinante importante de la caída en la tasa de crecimiento del PIB argentino durante el período 1901 - 2000. Partiendo de un ejercicio de...

This paper contains the results of a non parametric multi-step ahead forecast for the monthly Colombian inflation, using Mean conditional Kernel estimation over inflation changes, with no inclusion of exogenous variables. The results are compared with those from an ARIMA and a nonlinear STAR....

This paper studies the regional convergence of sub-national states in the case of Mercosur from 1961 to 2005 by using a non-parametric technique of clustering under the concept of \regime of performance". In the first section, a review in interregional convergence is shown for the Mercosur case....

Empirical applications for assessing the efficiency in cultural organizations are still scarce. In this paper, we use a non-radial, output-oriented, DEA model for assessing the efficiency of a sample of 292 Musical Societies in the Valencian Community. The interest in this type of cultural...
