Public child care is expected to assist families in reconciling work with family life. Yet, empirical evidence for the relevance of public child care to maternal employment is inconclusive. We exploit the introduction of a legal claim to a place in kindergarten in Germany, which was contingent on day-of-birth cut-off dates and resulted in a marked increase in kindergarten attendance of three-year olds in the following years. Instrumental variable and difference-indifferences estimations on two individual-level data sets yield large and positive effects of public child care on maternal employment. A set of placebo treatment tests corroborate the validity of our identification strategies. Terms of use: Documents in EconStor mayJEL-Code: J220, J130, D040.

This paper reviews the empirical economic literature on the relative importance of non cognitive skills for school and labour market outcomes, with a focus on Europe. There is evidence that high cognitive test scores are likely to result not only from high cognitive skills but also from high motivation and adequate personality traits. This suggests that part of the contribution of cognitive skills to economic growth could be due to personality traits. Across large parts of the literature, there is consensus that non cognitive skills have important effects both on school attainment and on labour market outcomes. These effects might be as important as the effects of cognitive skills. Less consensus exists on the malleability of non cognitive skills, with some arguing that these skills can be altered until the end of teenage years and others claiming that emotional intelligence can be changed at any age. Most of what economists know about the technology of non cognitive skill formation concerns early educational levels, such as preschools and schools. While it is difficult to argue that all relevant skill formation ends before labour market entry, there is scant evidence on the role of the workplace in the maintenance and development of existing skills. Clearly, more research in this area is needed.

Education policy-makers and practitioners want to know which policies and practices can best achieve their goals. But research that can inform evidence-based policy often requires complex methods to distinguish causation from accidental association. Avoiding econometric jargon and technical detail, this paper explains the main idea and intuition of leading empirical strategies devised to identify causal impacts and illustrates their use with real-world examples. It covers six evaluation methods: controlled experiments, lotteries of oversubscribed programs, instrumental variables, regression discontinuities, differencesindifferences, and panel-data techniques. Illustrating applications include evaluations of earlychildhood interventions, voucher lotteries, funding programs for disadvantaged, and compulsory-school and tracking reforms.

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.
