Fixed Effects Individual Slopes
Fixed effects (FE) panel models have been used extensively in the past, as those models control for all stable heterogeneity between units. Still, the conventional FE estimator relies on the assumption of parallel trends between treated and untreated groups. It returns biased results in the presence of heterogeneous slopes or growth curves that are related to the parameter of interest (e.g., selection into treatment is based on individual growth …
What You Need to Know When Estimating Impact Functions with Panel Data for Demographic Research
The estimation of impact functions - that is the time-varying causal effect of a dichotomous treatment (e.g., marriage, divorce, parenthood) on outcomes (e.g., earnings, well-being, health) - has become a standard procedure in demographic applications. The basic methodology of estimating impact functions with panel data and fixed-effects regressions is now widely known. However, many researchers may not be fully aware of the methodological subtle…
Is There a Male Marital Wage Premium? New Evidence from the United States
This study reconsiders the phenomenon that married men earn more money than unmarried men, a key result of the research on marriage benefits. Many earlier studies have found such a "male marital wage premium." Recent studies using panel data for the United States conclude that part of this premium is due to selection of high earners into marriage. Nevertheless, a substantial effect of marriage seems to remain. The current study investigates wheth…
Fixed-Effects Panel Regression
Domestic Work and the Wage Penalty for Motherhood in West Germany
Previous research suggests that household tasks prohibit women from unfolding their full earning potential by depleting their work effort and limiting their time flexibility. The present study investigated whether this relationship can explain the wage gap between mothers and nonmothers in West Germany. The empirical analysis applied fixed-effects models and used self-reported information on time use and earnings as well as monthly family and wor…
Abschreibungsraten allgemeiner und beruflicher Ausbildungsinhalte - empirische Evidenz auf Basis subjektiver Einschätzungen / Depreciation Rates of General and Vocational Training Capital - Evidence B…
The computer revolution together with educational expansion has led to dramatic changes in the structure of the workforce and in the organisation of workplaces in the last four decades. These developments should have different impacts on the use of vocational and general skills. This study compares depreciation rates of general and specific training capital among West German workers between 1979 and 1999. In this time the personal computer entere…
