SOEPpapers on Multidisciplinary Panel Data Research at DIW BerlinThis series presents research findings based either directly on data from the German SocioEconomic Panel Study (SOEP) or using SOEP data as part of an internationally comparable data set (e.g. CNEF, ECHP, LIS, LWS, CHER/PACO). SOEP is a truly multidisciplinary household panel study covering a wide range of social and behavioral sciences: economics, sociology, psychology, survey methodology, econometrics and applied statistics, educational science, political science, public health, behavioral genetics, demography, geography, and sport science.The decision to publish a submission in SOEPpapers is made by a board of editors chosen by the DIW Berlin to represent the wide range of disciplines covered by SOEP. There is no external referee process and papers are either accepted or rejected without revision. Papers appear in this series as works in progress and may also appear elsewhere. They often represent preliminary studies and are circulated to encourage discussion. Citation of such a paper should account for its provisional character. A revised version may be requested from the author directly.Any opinions expressed in this series are those of the author(s) and not those of DIW Berlin.Research disseminated by DIW Berlin may include views on public policy issues, but the institute itself takes no institutional policy positions.
AbstractStandard household economics assumes that couples pool their incomes and share the sum equally, which is a necessary prerequisite for computing equivalent incomes and hence all statements about the distribution of personal incomes and income poverty. However, since cohabitation without marriage is on the rise and since income pooling is less frequent among cohabiting couples, income is also pooled and shared less frequently. In conclusion, statements based on these two assumption are becoming increasingly invalid.Using data from the German Socio-Economic Panel Study, I analyze the incidence and determinants of income pooling and then proceed to determine whether couples who pool their incomes share the sum equally.In contrast to most existing studies, I use a holistic approach to identify sharing within households by analyzing data on financial satisfaction. Concerning the relation between income sharing and income pooling, I account not only for the dominance of pooling over sharing, but also for the possibility of correlated error ...
