The definition and operationalization of wealth information in population surveys and the corresponding microdata requires a wide range of more or less normative assumptions. However, the decisions made in both the pre- and post-data-collection stage may interfere considerably with the substantive research question. Looking at wealth data from the German SOEP, this paper focuses on the impact of collecting ...
The March Current Population Survey (CPS) is the primary data source for estimation of levels and trends in labor earnings and income inequality in the USA. Time-inconsistency problems related to top coding in theses data have led many researchers to use the ratio of the 90th and 10th percentiles of these distributions (P90/P10) rather than a more traditional summary measure of inequality. With access ...
The present study calculates variable, cross-sectional as well as longitudinal equivalence scales on the basis of the German 1984-2010 Socio-Economic Panel (SOEP) database for West Germany. It follows the "individual variant" for calculating subjective equivalence scales using "life satisfaction" as a proxy variable for "utility". The cross-sectional scale estimates are characterized by relatively ...
The effects of childbirth on future labor market outcomes are a key issue for policy discussion. This paper implements a dynamic treatment approach to estimate the effect of having the first child now versus later on future employment for the case of Germany, a country with a long maternity leave coverage. Effect heterogeneity is assessed by estimating ex post outcome regressions. Based on SOEP data, ...
We survey the literature on income mobility, aiming to provide an integrated discussion of mobility within- and between-generations. We review mobility concepts, descriptive devices, measurement methods, data sources, and recent empirical evidence.
Using representative micro data from the German Socio-Economic Panel Study (SOEP), this paper delivers new insights into the development of income inequality and regional stratification in Germany after unification. This paper applies a new method for detecting social stratification by a decomposition of the Gini index that yields the obligatory between- and within-group components as well as an 'overlapping' ...
Income as the traditional one dimensional measure in well-being and poverty analyses is extended in recent studies by a multidimensional poverty concept. Though this is certainly a progress, however, two important aspects are missing: time as an important dimension and the interdependence of the often only separately counted multiple poverty dimensions. Our paper will contribute to both aspects: First, ...
The paper investigates maternity leave behavior in West Germany for females being employed between 1995 and 2006 using data from the German Socio Economic Panel. The observational study focuses on the investigation of individual and family-related covariate effects on the duration of maternity leave following first or second childbirth, respectively. Dynamic duration time models are used in which covariate ...
Der Artikel untersucht die Indikatoreigenschaften der Geldmenge für die Inflation. Unter Verwendung eines P*-Modells hat Svensson (2000) theoretisch gezeigt, dass die Beziehung zwischen beiden Größen recht schwach ausgeprägt ist. Die vorliegende Studie präsentiert empirische Evidenz für die Beziehung im Euroraum. Dabei wird Svenssons Ansatz durch die Berücksichtigung verschiedener Schocks sowie unter ...
