The research objectives of this thesis were to contribute to Bayesian statistical methodology by contributing to risk assessment statistical methodology, and to spatial and spatio-temporal methodology, by modelling error structures using complex hierarchical models. Specifically, I hoped to...

Organizations that use time series forecasting on a regular basis generally forecast many variables, such as demand for many products or services. Within the population of variables forecasted by an organization, we can expect that there will be groups of analogous time series that follow...

Global marketing managers are keenly interested in being able to predict the salesof their new products. Understanding how a product is adopted over time allowsthe managers to optimally allocate their resources. With the world becoming evermore global, there are strong and complex interactions...

Diese Dissertation beinhaltet drei eigenständige Aufsätze, die die Interaktionen von Bewertungsmodellen für Wertpapiere, Finanzmärkten und der Volkswirtschaft untersuchen. Alle drei Papiere tragen zu einem besseren Verständnis von Verknüpfungen zwischen Finanzmärkten und Realwirtschaft....

W e develop a structural demand model that endogenously captures the effect of out-of-stocks on customer choice by simulating a time-varying set of available alternatives. Our estimation method uses store-level data on sales and partial information on product availability. Our model allows for...

Se propone una nueva medida de la inflación subyacente que informa, en tiempo real, sobre los riesgos asimétricos en las previsiones de inflación. Las asimetrías son generadas por no linealidades inducidas por la actividad económica. El nuevo indicador se basa en un modelo multivariante de...

This paper provides a synthesis and further development of a global modelling approach introduced in Pesaran, Schuermann and Weiner (2004), where country specific models in the form of VARX* structures are estimated relating a vector of domestic variables to their foreign counterparts and then...

Die vorliegende Dissertation zu makroökonomischen Themen beinhaltet einen einleitenden Literaturüberblick, drei eigenständige und voneinander unabhängige Kapitel sowie einen technischen Anhang. In Kapitel zwei wird ein Zwei-Länder Modell einer Währungsunion betrachtet, in dem die...

This dissertation is the collection of three essays aimed to evaluate the empirical performance of dynamic stochastic general equilibrium (DSGE) models in explaining the behavior of macroeconomic dynamics in emerging countries. Chapter 1, which is joint work with M. Uribe and R. Pancrazzi,...

The estimation of dynamic stochastic general equilibrium (DSGE) models is the subject of a rapidly growing literature. This dissertation contributes to the existing body of work by focusing on issues related to parameter identification.In the first essay I show that DSGE models are characterized...
