This paper analyses cyclical effects on job-to-job mobility using German data. The focus lies on the influence of the regional unemployment rate and the regional growth of the GDP. Job-to-job transitions are fragmented into external and internal movements. The innovation is to describe mobility...

In non-linear regression models, such as the heteroskedastic probit model, coefficients cannot be interpreted as marginal effects. Marginal effects can be computed as a non-linear combination of the regression coefficients. Standard errors of the marginal effects needed for inference and...

This paper investigates the effects of detailed job characteristics on job satisfaction, job search and quits using data from the German Socio-Economic Panel (GSOEP) in a fixed effects framework. Using a factor analysis, seventeen job characteristics are reduced to seven factors that describe...

CEO compensation that is perceived to be excessive regularly causes agitation in the population. Using German data, we show that perceiving CEO pay to be unjust has economic repercussions in terms of lower work morale.

In non-linear regression models, such as the probit model, coefficients cannot be interpreted as marginal effects. The marginal effects are usually non-linear combinations of all regressors and regression coefficients of the model. This paper derives the marginal effects in a probit model with a...

Using data from the German Socio-Economic Panel (GSOEP) we study whether being individually affected by downward wage rigidity has an effect on layoffs, quits and intra-firm mobility. Within a structural empirical model we estimate the individual extent of wage rigidity. This is expressed by the...

In diesem Beitrag wird die regionale Ausbreitung von COVID-19-Infektionen untersucht. Unter Verwendung der Hauptkomponentenanalyse, des LARS- und RLASSO-Auswahlverfahrens erfolgt eine Variablenreduktion. Geprüft wird die Bedeutung von Zustandsabhängigkeit, unbeobachteter Heterogenität und...

This paper presents a survey on panel data methods in which Iemphasize new developments. Inparticular, linear multilevel models with a new variant are discussed. Furthermore, non-linear, nonparametric and semiparametric models are analyzed. In contrast to linear models there do not exist unified...

This paper presents a survey on recent developments in estimation methods, instrumental variables approaches, panel data models, non- and semiparametric models for micro data. Additionally, some tests in these areas are considered. Special attention is paid to problems with weak instruments,...
