The series is aimed specifically at publishing peer reviewed reviews and contributions presented at workshops and conferences. Each volume is associated with a particular conference, symposium or workshop. These events cover various topics within pure and applied mathematics and provide up-to-date coverage of new developments, methods and applications.

This book reports new developments in applied econometrics. All papers originated in two international workshops that were organized in the University of Munich on July 6-7, 1989, and on January 11 - 12, 1990. Financial support for these conferences by the University of Munich and the Thyssen Foundation is gratefully acknowledged. Since then all papers were substantially revised and updated. We wish to thank all authors for their patience with the revisions and Thomas Bauer, Lucie Merkle and Gisela Loos for editorial help. The ftrst section of the book collects contributions that address new "Methodological Developments." Two of them deal with problems in microeconometrics, the other two consider multi-equation systems. Martin Kukuk and Gerd Ronning treat "Ordinal Variables in Microeconometric Models." They especially deal with the case of limited-dependent variable models where some exogenous variables are either measured on an interval scale or a nominal scale. They discuss and compare two methods to deal with the problem. In his paper on "Goodness of Fit in Qualitative Choice Models: Review and Evaluation," Klaus F. Zimmermann investigates methods to summarize the predictive quality of models that deal with discrete alternatives. For these models, a widely accepted measure for evaluation like the R2, as in the case of ordinary least squares, does not exist. The paper summarizes the literature and suggests reasonable choices for evaluation on the basis of large-scale Monte Carlo investigations.

Das Lehrbuch fuhrt in die heute als klassisch anzusehenden Methoden der OEkonometrie ein. Aufbauend auf dem unabdingbaren Fundament der Regressionsanalyse, enthalt es eine Darstellung der linearen dynamischen Systeme sowie der interdependenten Mehrgleichungsmodelle nebst den zugehoerigen Schatz- und Testverfahren. Auch der Prognosegesichtspunkt findet Beachtung. Eine Einfuhrung in die Bayes-Theorie wird ebenfalls gegeben. Soweit sie fur die OEkonometrie von Bedeutung sind, wird in der 4. Auflage eine starkere Betonung auf die Modelle mit fehlerbehafteten Daten gelegt. Auf neuere Entwicklungen in der OEkonometrie wird hingewiesen, ebenso sind die Literaturangaben uberarbeitet. Dem praktisch arbeitenden OEkonometriker gibt das Buch das Werkzeug fur seine Arbeit in die Hand und nennt die theoretischen Voraussetzungen fur das Funktionieren dieses Werzeugs.
