The German schooling system selects children into different secondary school tracks already at a very early stage in life. School track choice heavily influences choices and opportunities later in life. It has often been observed that secondary schooling achievements display a strong correlation...

This paper analyses the duration of child poverty in Germany. In our sample, we observe the entire income history from the individuals? birth to their coming of age at age 18.Therefore we are able to analyze dynamics in and out of poverty for the entire population of children, whether they...

Using a panel of household travel diary data collected in Germany between 1997 and 2005, this study assesses the effectiveness of fuel efficiency improvements by econometrically estimating the rebound effect, describing the extent to which higher efficiency causes additional travel.Following a...

Measures of Active Labor Market Policy are widely used in European countries, but despite many econometric evaluation studies no conclusive cross-country evidence exists regarding ?what program works for what target group under what (economic and institutional) circumstances??. This paper...

Any researcher would certainly agree with Hamermesh?s (1993:34) intuition about separability that the ease of substitution between any two production factors should be unaffected by a third factor that is separable from the others. This paper emphasizes that such a notion of separability needs...

This paper illustrates two techniques for calculating the statistical significance of the marginal effects derived from Heckman?s sample selection model,an increasingly common econometric specification in political science. The discussion draws on an analysis by Sweeney (2003) of the incidence...

This analysis shows that multivariate generalizations to the classical Heckman (1976 and 1979) two-step estimator that account for cross-equation correlation and use the inverse Mills ratio as a correction-term are consistent only if certain restrictions apply to the true error-covariance...
