Works Councils and Establishment Productivity

Steffen Müller

ILR Review, No. 4, 2012

Abstract

Declining union density in many industrialized countries increases interest in alternative forms of employee representation, such as works councils. The German works council is one of the most powerful forms of worker representation in developed countries, but little is known of its causal effect on productivity. The author used a large linked employer-employee panel data set to examine this issue. Comparing firms with and without a works council, the author finds that establishments with a works council are on average 6.4% more productive; but he also presents evidence that this figure underestimates the true productivity effect of works councils.

Human Capital and Fertility in Germany after 1990: Evidence from a Multi-Spell Model

Marco Sunder

IWH Discussion Papers, No. 22, 2009

Abstract

We analyze the timing of birth of the first three children based on German panel data (GSOEP) within a hazard rate framework. A random effects estimator is used to accommodate correlation across spells. We consider the role of human capital – approximated by a Mincer-type regression – and its gender-specific effects on postponement of parenthood and possible recuperation at higherorder births. An advantage of the use of panel data in this context consists in its prospective nature, so that determinants of fertility can be measured when at risk rather than ex-post, thus helping to reduce the risk of reverse causality. The analysis finds evidence for strong recuperation effects, i.e., women with greater human capital endowments follow, on average, a different birth history trajectory, but with negligible curtailment of completed fertility.
