      Using longitudinal data from the German Socio-Economic Panel (SOEP), this article examines whether gender wage differentials occur due to differences in prototypical personality traits of women and men and provides the first application of a gender wage gap decomposition on the basis of a correlated random effects model. Main results show that agreeableness and openness are the most important personality ...

      This article examines heterogeneity in the effect of unemployment on social participation. Whereas existing studies on this relationship essentially estimate mean effects, we use quantile regression methods to provide a broader and more complete picture. To ac-count for the potential endogeneity of job loss, we estimate quantile treatment effects (on the treated) based on entropy balancing and focus ...

      This paper uses data from the Migrant Samples of the German Socio-Economic Panel to study the fertility behaviour of women who migrated to Germany between 1990 and 2015. Special emphasis is placed on the large groups of migrants who have moved t

      • SOEPpapers 495 / 2012

        This paper deals with long distance internal migration patterns of the immigrant population in Germany and addresses the question whether immigrants are more mobile than native Germans and to what extent the differences in spatial mobility behavior between immi-grants and native Germans are influenced by a) individual level characteristics, b) macro level regional economic characteristics and c) regional ...

        Human capital theory predicts pecuniary returns to regional migration, but also positive self-selection of migrants. Therefore, when estimating the causal effect of migration one has to take care of potential self-selection. Several authors recommend using fixed effects models thereby controlling for time constant unobserved heterogeneity. However, if selection operates not only on wage level but also ...

        This paper investigates gender differences in the spatial mobility of young adults when initially leaving their parental home. Using individual data from 11 waves (2000-2010) of the SOEP, we examine whether female home leavers in East Germany move ac
