Unskilled labor and wage determination: an empirical investigation for Germany
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...

Employment Prospects and Skill Acquisition of Apprenticeship-Trained Workers in Germany
Using data from the German Socio-Economic Panel for 1984-90, the author analyzes the entrance of young individuals into the German labor market, comparing the experience of apprenticeship graduates to that of graduates from universities, full-time vocational schools, and secondary schools. Apprentices experienced fewer unemployment spells in the transition to their first full-time...

Markov Chain Monte Carlo analysis of underreported count data with an application to worker absenteeism
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.

Discriminatory versus uniform Treasury auctions: Evidence from when-issued transactions
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...

Evaluation von Hochschulleistungen, Leistungsindikatoren und Performance Measurements
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...

A Comparison of US, UK, and German Insolvency Codes
This paper describes three insolvency codes, those of the United Kingdom (UK), Germany, and the United States (US) and compares their efficiency against a number of benchmarks. These codes have been chosen because they cover a broad spectrum of debtor- and creditor-oriented insolvency procedures. The paper also compares the plans of distressed firms' reorganizations both within...

Die theoretische Fundierung unvollständiger Verträge
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...

ECOSYS-87: Model Calculations of the activity in cow meat related to deposition time and feeding regimes after a nuclear fallout
The radioecological model ECOSYS-87 was used to evaluate the effect of countermeasures for reducing the ingestion dose by eating cattle meat after an accidental release of radioactive material. Calculations were performed using a database adapted to Swiss conditions for the case that (1) contaminated grass or hay is replaced by clean fodder; (2) the last 100 days before slaughter,...

A look at the Nd as a special case of CNV
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...

A fair mechanism for the efficient reduction of global CO2-emissions
Because of the public good character of global emissions it is difficult to implement reduction
targets as formulated at Toronto or Rio. This paper presents a simple mechanism for inducing
efficient contributions to the reductions of emissions as a non-cooperative equilibrium. The
world is partitioned into groups of countries, and then each country is taxed or...

Retirement of spouses and social security reform
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...

The cross-country Engel curve for product diversification
This paper employs ICP expenditure data to investigate the relationship between income and product diversity. It turns out that per-capita income has a strong positive impact on the number of products consumed at a non-negligible level in a country, and a significant negative impact on the concentration of consumers' expenditure across different goods categories. Inequality in...

Tax evasion, consumption of public goods and fairness
This study shows that in general the impact of equity on tax evasion depends on how the taxpayer's risk aversion is affected by perceived equity. Then possible reasons are discussed why an increase in perceived equity may increase a person's risk aversion and thus lead to a decrease of evasion. An economic as well as a psychological argument are presented which can explain...

Energy security Coping with multiple supply risks
This study starts from the observation that today's Western trading nations are exposed to multiple risks of energy supplies, eg simultaneous shortage of oil and gas supplies. To cope with these risks, both oil and gas can be stockpiled. Adopting the viewpoint of a policy maker who aims at minimizing the expected cost of security of supply, optimal simultaneous adjustments of...

Diffusion of hospital innovations in different institutional settings
This paper purports to analyze a hospital's adoption of both product and process innovation as a quantal choice. The impacts of this decision on physicians, while depending on institutions that differ between the US and continental Europe, are shown to feed back to the hospital, influencing the profitability of the innovation. Recent changes of hospital finance give rise to...

Collective action, migration and welfare states
In current welfare state analysis there is little theory to explain the action of exclusive groups. This article explores the possibilities of a theory that focuses on the interaction between individual choices and strategies, the formal systems, policies and rules of governments and the informal norms and practices of groups. The argument is that club theory, a branch of public...

Happiness and unemployment: a panel data analysis for Germany
We use data from the German Socio-Economic Panel to investigate how individual happiness is affected by unemployment. Unemployment has a large and negative effect even after controlling for individual specific fixed effects. Nonparticipation, in contrast, is much less harmful to happiness. Further, we decompose the total well-being costs of unemployment and find that well above three...

Duration dependence and dispersion in count - data models
This paper explores the relation between non-exponential waiting times between events and the distribution of the number of events in a fixed time interval. It is shown that within this framework the frequently observed phenomenon of overdispersion, i.e. a variance that exceeds the mean, is caused by a decreasing hazard function of the waiting times, while an increasing hazard...
