The importance of empirical economics and econometric methods has greatly in­ creased during the last 20 years due to the availability of better data and the improved performance of computers. In an information-driven society such as ours we need quickly to obtain complete and convincing statistical results. This is only possible if the appropriate econometric methods are applied. Traditional econometric analysis concentrates on classical methods which are far from suitable for handling actual economic problems. They can only be used as a starting point for students to learn basic econometrics and as a reference point for more advanced methods. Modern Econometrics tries to develop new approaches from an economic perspective. A consequence is that we have less of a unified econometric theory than in former times. Specific branches which require specific methods have been established. Nowadays, nobody has complete knowledge of every area of econometrics. If someone is interested to learn more about a field, relatively unknown to them, they will require support.

Für die Beurteilung umweltpolitischer Maßnahmen müssen neben dem Grad der Zielerreichung auch die Effekte im ökonomischen und ökologisch-technischen Gesamtsystem prognostiziert werden. Dazu haben sich disaggregierte makroökonometrische Modelle als besonders nützlich erwiesen. In einem vom Umweltbundesamt initiierten Projekt wurden erstmals im deutschsprachigen Raum zwei verschiedene Modelle parallel benutzt. Die Zuverlässigkeit wurde dadurch erheblich verbessert. Das Modell PANTA RHEI der GWS (Osnabrück) und der Modellverbund des RWI (Essen) wurden um die Umweltbereiche Wasser, Klima, Luft und Boden erweitert und dann zur Simulation folgender umweltpolitischer Maßnahmen eingesetzt: Ökosteuer, Flächensteuer (jeweils verschiedene Varianten), Flächenangebots-Beschränkung, CO2-Steuer. Das Buch enthält die Beschreibung der Modellstrukturen, die Darstellung der Simulationen und eine vergleichende Diskussion der Ergebnisse.
