Dieser Beitrag wägt Vorteile und Nachteile verschiedener Flexibilisierungsstrategien ab, die der Stabilisierung des Beschäftigungsniveaus dienen. Insgesamt zeigt sich, daß Arbeitszeitflexibilisierung durch Arbeitszeitkonten alternativen kurzfristig ausgerichteten Anpassungsmechanismen aus...

The question of a double dividend from revenue-neutral ecological tax reforms (an ecological advantage plus an economic advantage) has recently become a widely discussed topic both in real-world economic policy and in economic theory. The subject has produced many advocates and opponents in the...

This paper proposes simple Hausman-type tests to check for bias in the log-periodogram regression of a time series believed to be long memory. The statistics are asymptotically standard normal on the null hypothesis that no bias is present, and the tests are consistent. The use of the tests in...

Das Papier untersucht, wie Erwartungsbildung mit Hilfe neuronaler Netze modelliert werden kann. Die Grundlage bildet ein Cobweb-Modell, in dem Firmen Preiserwartungen auf Basis eines Feedforward-Netzes bilden.Zunächst wird anhand von Simulationen gezeigt, daß Firmen durch neuronale...

This paper considers blockwise empirical likelihood for real-valued linear time processes which may exhibit either short- or long-range dependence. Empirical likelihood approaches intended for weakly dependent time series can fail in the presence of strong dependence. However, a modified...

This paper analyzes the relationship between the expectational stability of rational expectations equilibria and the possible convergence of adaptive learning processes. Results obtained using recursive least squares lead to the conjecture that a correspondence between these both selection...
