Twin births are often used to instrument for fertility when investigating the impact of family size on labor market outcomes. In this paper we consider two econometric problems both related to the link between fertility treatments and multiple births. The first is the potential for omitted...

Twin births are often used as an instrument for fertility in models investigating the impact of family size on labour market and child outcomes. However, a large share of twin births (24% in our sample) are the result of fertility treatments, potentially causing twin births to be endogenous and...

We study the link between parental selection and children criminality in a new context. After the fall of the Berlin Wall, East Germany experienced an unprecedented temporary drop in fertility driven by economic uncertainty. We exploit this natural experiment to estimate that the children from...

After the fall of the Berlin Wall, East Germany experienced an unprecedented temporary drop in fertility driven by economic uncertainty. Using various educational measures, we show that the children born during this nativity slump perform worse from an early age onwards. Consistent with negative...

Following the collapse of the Berlin Wall, the birth rate halved in East Germany. Despite their small sizes, the cohorts conceived during this period of socio-economic turmoil were, as they grew up in reunified Germany, markedly more likely to be arrested than cohorts conceived a few years...

Do people born at different points of the economic cycle have different outcomes - and if so, why? Arnaud Chevalier and Olivier Marie examine the educational attainment and criminal activity of children born in East Germany in the few years after the fall of the Berlin Wall - a time when...
