Development of the Decision Support System (DSS) used by the National Emergency Operations Centre in Switzerland began immediately after the accident at Chernobyl. The system will evaluate acceptable countermeasures following the accidental release of radioactivity in order to reduce ingestion dose. The DSS - not designed for the very early phase following the accidental release of...

This article contributes to the ongoing debate on native wage impacts of immigration. I propose a mobile-fixed factor distinction as a framework in which to think about the differential impact of immigration on various labor market groups. Skilled workers are treated as a fixed factor of production since the strong reliance on skill certification in Germany inhibits mobility and...

A new approach for modeling under-reported Poisson counts is developed. The parameters of the model are estimated by Markov Chain Monte Carlo simulation. An application to workers absenteeism data from the German Socio-Economic Panel illustrates the fruitfulness of the approach. Worker absenteeism and the level of pay are unrelated, but absence rates increase with firm size.

We use wehn-issued transactions data to assess the Treasury's current experiment with uniform auctions, suggesting a higher information release, which should reduce pre-auction uncertainty and the winner's curse. Under uniform auctions, wehn-issued volatility falls after the auction and again after the outcome announcement. The pattern is the opposite for discriminatory...

Aufgrund der zunehmenden Studentenzahlen und der hohen Investitionen in Forschungs- und Bildungseinrichtungen beanspruchte der Hochschulbereich in den letzten Jahren immer mehr öffentliche Mittel mit steigender Tendenz. Wurden die Hochschulbudgets bis anhin von den Parlamenten weitgehend stillschweigend genehmigt, wird dies - aufgrund der knappen Ressourcen - in Zukunft kaum mehr der...

Innerhalb der Kontrakttheorie hat sich im vergangenen Jahrzehnt die Theorie unvollständiger Verträge als besonders fruchtbar erwiesen. Jüngste Forschungsarbeiten zeigen jedoch, daß die durch Hart und Moore (1988) als gegeben geglaubte Fundierung nicht sehr robust ist. Ziel des Artikels ist es, einen Einblick in aktuelle Fragen und Ergebnisse der diesbezüglichen Forschung zu...

Tone onset and normal tone offset in Nd tasks are formally similar to the S1 and S2 events in a CNV task requiring perceptual discrimination (tone duration) for designated tones. If the Nd thus reflects more than mere stimulus selection, increasing the duration of all tones should lengthen the Nd wave. Eight subjects participated to three Nd tasks, with short tones of 50, 150, and...

The retirement decisions of spouses may be interdependent for various reasons: similarity of tastes, joint assets, sharing rules for income and housework, or complementarity of leisure. Because of data limitations, only a few empirical studies exist on this topic. From a policy point of view interdependent retirement could become important if legislators in different EC countries are...
