Social Indicators Research: "Estimating Extended Income Equivalence Scales from Income Satisfaction and Time Use Data" (Borah)

08.06.2020 -

New publication by Melanie Borah:

In this paper, I estimate extended income equivalence scales from income satisfaction and time-use data contained in the German Socio-Economic Panel. Designed to capture the needs of additional household members, these scales account for both, increases in households’ money income and domestic production requirements. The estimation procedure determines equivalence weights in these two components separately by combing the subjective with the objective approach. The findings suggest greater monetary equivalence weights for adults than for children, whereas household production increases more strongly in the number of children than in the presence of an adult partner. Differences in relative needs tend to balance out in the extended income equivalence scale, assigning additional adults and children almost identical weights of about 45%. I illustrate the implications of these estimates for measures of income inequality using the same dataset.

Perspektiven der Wirtschaftspolitik: "Prognosen und empirische Befunde: Wie groß ist die Kluft beim Mindestlohn wirklich?" (Knabe, Schöb, Thum)

06.04.2020 -

Neue Publikation von Andreas Knabe, Ronnie Schön und Marcel Thum:

Die sehr negativen Prognosen zur Beschäftigungswirkung der Einführung des Mindestlohns in Deutschland hätten sich nicht bewahrheitet, schrieben Oliver Bruttel, Arne Baumann und Matthias Dütsch in den PWP 3/2019. Andreas Knabe, Ronnie Schöb und Marcel Thum halten dem in diesem Beitrag entgegen, dass sich Prognosen und tatsächliche Beschäftigungswirkungen des Mindestlohns gar nicht wesentlich unterscheiden. Zum einen hätten sich die Beschäftigungsverluste bisher stark in einer Reduktion der Zahl der Arbeitsstunden je Beschäftigten niedergeschlagen. Zum anderen erhielten weiterhin viele Arbeitnehmer weniger als den Mindestlohn, was die bislang messbaren negativen Beschäftigungswirkungen mindere.

Sozialer Fortschritt: "Non-Compliance With The Compulsory Employment Quota Of Severely Disabled People - An Empirical Investigation Of Potential Causes At The German Federal State Level" (Borah, Hahn, Knabe)

21.01.2020 -

New publication by Melanie Borah, Kathrin Hahn and Andreas Knabe:

This paper examines factors that can explain substantial differences in the employment rate of several 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.

The Review of Income and Wealth: "Reference Income Effects in the Determination of Equivalence Scales Using Income Satisfaction Data" (Knabe, Borah, Keldenich)

09.12.2019 -

New Publication by Andreas Knabe, Melanie Borah und Carina Keldenich:

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.

Oxford Economic Papers: "How Much Does Others' Protection Matter? Employment Protection, Future Labour Market Prospects and Well-Being" (Knabe, Lücke)

04.08.2019 -

New Publication by Andreas Knabe and Christine Lücke, (online first):

Employment protection legislation (EPL) is an important determinant of workers’ perceived future labour market prospects as well as their subjective well-being. Recent studies indicate that it is not only a worker’s own level of protection, but also the employment protection of other workers that matters for individual prospects and well-being. We contribute to this literature by examining how such cross-effects on well-being are mediated by a workers’ perceived risk of job loss and future employability. We apply a structural model to data from the Third Wave of the European Quality of Life Survey, combined with summary indices from the OECD Employment Protection Database. Our results are indicative of cross-effects. Stricter protection for permanent workers (stricter regulation on the length and number of renewals of fixed-term contracts) is associated with lower (higher) perceived employability for both permanent workers and fixed-term workers. In addition, stricter protection for permanent workers is positively related to fixed-term workers’ perceived risk of job loss. We do find some evidence that EPL has significant indirect (cross-)effects on life satisfaction via the mediators. There are no indications for direct, non-mediated effects.
