Using Analysis of Gini (ANOGI) for Detecting Whether Two Subsamples Represent the Same Universe

Year: 2006

Type: article

Abstract: A particular shortcoming of panel surveys is potential bias arising from selective attrition.Based on data from the German Socio-Economic Panel Study (SOEP) we analyze potentialartifacts (level, structure, inequality of income) by comparing results from two independentlydrawn panel sub-samples, started in 1984 and 2000, respectively. Both sub-samples carriedon using the same set of follow-up rules. We apply ANOGI (ANalysis Of GIni) techniques, theequivalent of ANOVA (ANalysis Of VAriance) performed on the basis of the Gini coefficient.The decomposition followed is presented in Yitzhaki (1994). We rearrange, reinterpret anduse the decomposition in the comparison of sub-populations from which the different subsampleswere drawn. Taking into account indicators for income, and for control purposesthose for education and satisfaction as well, significant differences between these two subsampleswith respect to (income) inequality are found in the first year, which start to fadeaway in wave 2 and disappear in wave 3. We find credible indication for these differences tobe driven by changes in response behavior of short term panel members rather than byattrition among members of the longer running sub-sample.
