We use a large linked employer-employee data set to analyze the importance of relative wage positions in the context of individual quit decisions as an inverse measure of job satisfaction. Our main findings are: (1) Workers with higher relative wage positions within their firms are on average...

We use a long panel data set for four entry cohorts into an internal labor market to analyze the effect of age on the probability to participate in different training measures. We find that training participation probabilities are inverted u-shaped with age and that longer training measures are...

In recent years layoffs have increasingly become the focus of public attention. So far, however, there has been no representative study for Germany of how far and under what conditions layoffs are accepted by the population - in other words by people who are not immediately affected. Principles...

Human capital and deferred compensation might explain why firms employ but do not hire older workers. Adjustments of wage-tenure profiles for older new entrants are explored in the context of deferred compensation. From an equity theory perspective, such adjustments might lead to adverse...

Atheoretical regression trees (ART) are applied to detect changes in the mean of a stationary long memory time series when location and number are unknown. It is shown that the BIC, which is almost always used as a pruning method, does not operate well in the long memory framework. A new method...

The village funds programme in Thailand is one of the biggest microfinance programmes in the world aiming at improving access to finance and income in rural areas. Earlier studies indicate that the programme is successful in realising its ambitions to some degree. We extend this work by...

We study the problem of determining both the structure and the schedule of projects subject to capacity constraints. We assume that those projects are flexible in the sense that the activities to be implemented are not entirely known in advance. In such a setting, decisions must be made with...

This paper provides a multivariate score-type test to distinguish between true and spurious long memory. The test is based on the weighted sum of the partial derivatives of the multivariate local Whittle likelihood function. This approach takes phase shifts in the multivariate spectrum into...

This paper analyzes and quantifies the idea of model risk in the environment of internal model building. We define various types of model risk including estimation risk, model risk in distribution and model risk in functional form. By the quantification of these concepts we analyze the impact of...

We consider a recently proposed class of nonlinear time series models and focus mainly on misspecification testing for models of such type. Following the modeling cycle for nonlinear time series models of specification, estimation and evaluation we first treat how to choose an adequate...
