Regional Income Stratification in Unified Germany Using a Gini Decomposition Approach

This paper delivers new insights into the development of income inequality and regional stratification in Germany after unification using a new method for detecting social stratification by a decomposition of the GINI index which yields the obligatory between- and withingroup components as well as an "overlapping" index for the different sup-populations. We apply this method together with a jackknife estimation of standard errors. We find that East Germany is still a stratum on its own when using post-government income, but since 2001 no longer is when using pre-government income. These results remain stable when using alternatively defined regional classifications. However, there are also indications of some regional variation within West Germany. Overall, these findings are important for the political discussion with respect to a potential regional concentration of future transfers from East to West Germany.Inequality decomposition; Gini; Stratification; German unification; Regional disparities; SOEP

Individual Well-Being in a Dynamic Perspective

This paper explores the determinants of individual well-being as measured by self-reported levels of satisfaction with income. Making full use of the panel data nature of the German Socio-Economic Panel, we provide empirical evidence for well-being depending on absolute and on relative levels of income in a dynamic framework. This finding holds after controlling for other influential factors in a multivariate setting. The main novelty of the paper is the consideration of dynamic aspects: individual's own history as well as the relative income performance with respect to the others living in the society under analysis do play a major role in the assessment of well-being.Interdependent Preferences, Inequality Aversion, Status, Subjective Well-Being, SOEP

Measuring Income in Household Panel Surveys for Germany: A Comparison of EU-SILC and SOEP

Empirical analyses of economic inequality, poverty, and mobility in Germany are, to an increas-ing extent, using microdata from the German Federal Statistical Office's contribution to the European Union Statistics on Income and Living Conditions (EU-SILC) as well as data from the German Socio-Economic Panel (SOEP). In addition to their significance for national reporting, the EU-SILC data are of great international significance for comparative EU-wide measurement, description, and analysis in support of the European Commission's stated objective of fighting poverty and reducing social inequality through the European social cohesion process. It is therefore crucial to assess the quality of the German contribution to EU-SILC, particularly in view of evidence in the literature of methodological problems in this still relatively young survey with respect to the representation of specific social groups and the distri-bution of key educational characteristics that can have a considerable impact on the degree and structure of inequality and poverty (see Hauser 2008, Causa et al. 2009, Nolan et al. 2009). While previous papers have critically examined the German EU-SILC contribution in comparison to the cross-sectional data from the German Survey of Income and Expenditure (EVS), the present paper compares EU-SILC-based results about income trends, inequality, and mobility with results based on SOEP, a widely used alternate panel survey of private households in Germany. The - in some cases severe - differences identified are discussed in the context of the surveying and interviewing methods, post-data-collection treatment of the micro-data as well as sample characteristics of the two studies, all of which exert a major influence on the substantive results and thus on the core findings regarding the social situation of Germany in EU-wide comparison.Inequality, poverty, mobility, household panel, EU-SILC, SOEP

Subjective Well-Being and Relative Deprivation: An Empirical Link

This paper explores the relationship between two well-established con-cepts of measuring individual well-being: the concept of happiness, i.e. self-reported level of satisfaction with income and life, and relative deprivation/satisfaction, i.e. the gaps between the individual's income and the incomes of all individuals richer/poorer than him. Operationalizing both concepts using micro panel data from the German Socio-Economic Panel, we provide empirical evidence for subjective well-being dependingmore on relative satisfaction than on absolute levels of income. This finding holds even after controlling for other influential factors in a multivariate setting.Relative deprivation; Satisfaction; Subjective well-being; SOEP

Revisiting the Income-Health Nexus: The Importance of Choosing the "Right" Indicator

We show that the choice of the welfare measure has a substantial impact on the degree of welfare-related health inequality. Combining various income and wealth measures with different health measures, we calculate 80 health concentration indices. The influence of the welfare measure is more pronounced when using subjective health measures than when using objective health measures.health inequality, concentration index, income measurement, SOEP

Item Non-response and Imputation of Annual Labor Income in Panel Surveys from a Cross-National Perspective

Using data on annual individual labor income from three representative panel datasets (German SOEP, British BHPS, Australian HILDA) we investigate a) the selectivity of item non-response (INR) and b) the impact of imputation as a prominent post-survey means to cope with this type of measurement error on prototypical analyses (earnings inequality, mobility and wage regressions) in a cross-national setting. Given the considerable variation of INR across surveys as well as the varying degree of selectivity build into the missing process, there is substantive and methodological interest in an improved harmonization of (income) data production as well as of imputation strategies across surveys. All three panels make use of longitudinal information in their respective imputation procedures, however, there are marked differences in the implementation. Firstly, although the probability of INR is quantitatively similar across countries, our empirical investigation identifies cross-country differences with respect to the factors driving INR: survey-related aspects as well as indicators accounting for variability and complexity of labor income composition appear to be relevant. Secondly, longitudinal analyses yield a positive correlation of INR on labor income data over time and provide evidence of INR being a pre-dictor of subsequent unit-non-response, thus supporting the "cooperation continuum" hy-pothesis in all three panels. Thirdly, applying various mobility indicators there is a robust picture about earnings mobility being significantly understated using information from completely observed cases only. Finally, regression results for wage equations based on observed ("complete case analysis") vs. all cases and controlling for imputation status, indicate that individuals with imputed incomes, ceteris paribus, earn significantly above average in SOEP and HILDA, while this relationship is negative using BHPS data. However, once applying the very same imputation procedure used for HILDA and SOEP, namely the "row-and-column-imputation" approach suggested by Little & Su (1989), also to BHPS-data, this result is reversed, i.e., individuals in the BHPS whose income has been imputed earn above average as well. In our view, the reduction in cross-national variation resulting from sensitivity to the choice of imputation approaches underscores the importance of investing more in the improved cross-national harmonization of imputation techniques.Item non-response, imputation, income inequality, income mobility, panel data, SOEP, BHPS, HILDA

Old-Age Pension Entitlements Mitigate Inequality: But Concentration of Wealth Remains High

Entitlements from old-age pension schemes - statutory, company, and private - represent a considerable source of wealth. For data-related reasons, analyses of the personal wealth distribution have so far failed to take this into account, however. According to recent calculations based on the 2007 data of the German Socio- Economic Panel (SOEP), the present value of total pension and state annuity entitlements (not including entitlements to provision for dependants) amounted to roughly 4.6 trillion euros. This corresponds to an average of 67,000 euros per adult. When this is combined with individuals' financial and material assets, which amount to an average of 88,000 euros, the result is a more comprehensive total net worth of more than 155,000 euros. Civil servants and retired civil servants fare better than average if this larger view is taken. This more comprehensive measurement shows considerably less inequality of wealth than traditional analyses, which refer only to financial and material assets. This is not least because of the very widespread existence of entitlements under the various old-age pension schemes with simultaneous capping based on the contribution assessment threshold for statutory pension schemes. Nevertheless, wealth continues to be highly concentrated, and the mitigating effects of old-age pension assets will likely become less important in the future. Here the effects of falling pension levels as a result of reforms in the old-age pension systems and growing gaps in earnings histories will be felt - with the risk of increasing poverty among the future elderly.Wealth inequality, Pension entitlements, SOEP
