The problem of diagnostic checking is tackled from the perspective of the subspace methods. Two statistics are presented and its asymptotic distributions are derived under the null. The procedures generalize the Box-Pierce statistic for single series and the Hoskings' statistic in the...

A new procedure to predict with subspace methods is presented in this paper. It is based on combining multiple forecasts obtained from setting a range of values for a specic parameter that is typically xed by the user in the subspace methods literature. An algorithm to compute these predictions...

In this paper we analyse the market integration process of the relative price distribution, develop a model to analyze market integration, and present a formal test of increasing market integration. We distinguish between the economic concepts of price convergence in mean and in variance. When...

Este artículo describe una metodología que permite contrastar la convergencia absoluta y relativa del nivel general de precios (en media y varianza), basada en un modelo de precios relativos que incluye un proceso de transición y permite medir la velocidad de convergencia de precios entre un...

Este documento propone un modelo estadístico y un marco conceptual para estimar la volatilidad de la inflación suponiendo rational inattention, donde la caída del nivel de atención responde a la llegada de noticias al mercado. Estimamos la tendencia y la volatilidad condicional de la...
