We estimate household equivalence scales, i.e. the needs of additional adults and children relative to a single adult, using income satisfaction data from the German Socio-Economic Panel. We extend previous studies applying this approach by taking reference income into account. This allows separating needs-based from reference effects in the determination of income satisfaction. We show that this adjustment helps to overcome a bias causing an overestimation of adults' and an underestimation of children's needs-based equivalence weights. Our results indicate that controlling for income comparisons substantially increases children's equivalence weight relative to that of adults.JEL Codes: I32, J13, D31

An important aspect when analyzing economic inequality between households with children is time. At given monetary incomes, the material well-being of families may be very different depending on how much time parents have at their disposal. In this paper, we provide estimates of the subjectively perceived cost of children depending on the extent of parental time restrictions. Building on a study by Koulovatianos, Schröder and Schmidt (J. Bus. Econ. Stat. 27:42–51, 2009) that introduces a novel way of using subjective income evaluation data for such estimations, we conduct a refined version of the underlying survey, focusing on young women with children in Germany. Our study confirms that the perceived monetary cost of children is substantial and increases with parental nonmarket time restrictions. The experienced loss in material living standards associated with supplying time to the labor market is sizeable for families with children.

Zusammenfassung Diese Studie untersucht Faktoren, die die teilweise starken Unterschiede in der Beschäftigungsquote Schwerbehinderter zwischen den deutschen Bundesländern im Zeitraum von 2003 bis 2015 erklären können. Sie legt dabei besonderen Wert auf die Situation in Sachsen-Anhalt, das in diesem Zeitraum die deutschlandweit niedrigste Beschäftigungsquote aufweist. Die multivariate statistische Analyse liefert Hinweise darauf, dass der Erfüllungsgrad der Beschäftigungspflichtquote nach § 154 SGB IX in stärkerem Ausmaß von soziodemografischen als von ökonomischen Strukturmerkmalen der Länder bestimmt wird. Als Hauptdeterminante tritt in dem hier spezifizierten Modell der Anteil der (registrierten) Schwerbehinderten an der Gesamtbevölkerung hervor. Abstract: Non-Compliance With The Compulsory Employment Quota Of Severely Disabled People – An Empirical Investigation Of Potential Causes At The German Federal State Level This paper examines factors that can explain substantial differences in the employment rate of severely disabled people between the German federal states from 2003 to 2015. It puts special emphasis on the situation in Saxony-Anhalt, which had the lowest employment rate of disabled persons nationwide during this time. The multivariate statistical analysis provides evidence that the degree of compliance with the compulsory employment quote is determined by socio-demographic rather than economic characteristics of the states. Within the specified model, the main determinant of the employment rate appears to be the share of (registered) severely disabled people in the population.
