The effect of working time preferences and fair wage perceptions on entrepreneurial intentions among employees

To date, little is known about how working time preferences and fair wage perceptions affect employees’ entrepreneurial intentions. Using data from the German Socio-Economic Panel Study, we provide first evidence that the difference between the actual and desired amount of working hours in paid employment is positively related to the propensity to switch to self-employment. Furthermore, our analysis ...

Forecasting Behavioural and Distributional Effects of the Bofinger-Walwei Model using Microsimulation

Since Germany's social assistance reform ("Hartz-IV-Reform") in 2005 there has been a strong increase in the number of working poor and long-term unemployed. This development is often attributed to the remaining disincentives of the reformed social assistance to take up a low-paid full time job. Therefore, several proposals have been worked out to reduce these disincentives. In this ...

Restricted likelihood ratio testing in linear mixed models with general error covariance structure

We consider the problem of testing for zero variance components in linear mixed models with correlated or heteroscedastic errors. In the case of independent and identically distributed errors, a valid test exists, which is based on the exact finite sample distribution of the restricted likelihood ratio test statistic under the null hypothesis. We propose to make use of a transformation to derive the ...

Voluntary Turnover: What We Measure and What It (Really) Means

In this paper, we run regression analyses to explain voluntary turnover intentions with data from more than 5,000 employees and with about 250 explanatory variables.

We show the relevance of the so-called omitted variable bias to our findings ...
