We consider the problem of scheduling jobs online, where jobs may be served partially in order to optimize the overall use of the machines. Service requests arrive online to be executed immediately; the scheduler must decide how long and if it will run a job (that is, it must fix the Quality of Service level of the job) at the time of arrival of the job: preemption is not allowed. We give lower...

We compute rationally the topological (complex) K-theory of the classifying space BG of a discrete group provided that G has a cocompact G-CW -model for its classifying space for proper G-actions. For instance word-hyperbolic groups and cocompact discrete subgroups of connected Lie groups satisfy this assumption. The answer is given in terms of the group cohomology of G and of the centralizers ...

Multiple Glass Ceilings Both vertical (between job levels) and horizontal (within job levels) mobility can be sources of wage growth. We find that the glass ceiling operates at both margins. The unexplained part of the wage gap grows across job levels (glass ceiling at the vertical margin) and across the deciles of the intra-job-level wage distribution (glass ceiling at the horizontal margin). ...

Job Preferences as Revealed by Employee Initiated Job Changes Many previous studies try to discover job preferences by directly asking individuals. Since it is not sure, whether answers to these surveys are relevant for actual behaviour, this empirical examination offers a new approach based on representative German data. Employees who quit their job and find a new one, compare the two jobs wit...

This study compares the duration of new job matches in the east and west German labour market that formed between the start of the German Economic, Monetary and Social Union in July 1990 and December 2000. The study relies on job duration data drawn from the German Socio-economic Panel. It shows with non-parametric duration methods that job matches are less stable in east than in west Germany. ...

Job Insecurity and Future Labour Market Outcomes This paper uses longitudinal survey data to test the degree to which measures of job insecurity are correlated with changes in labour market status. Three major findings are reported. First, the perceived probability of job loss is only weakly related to both exogenous job separations and subsequent transitions to unemployment and inactivity. Sec...
