Sex ratios (males to females) rose markedly in China in the last two decades, and crime rates nearly doubled. This paper examines whether the two are causally linked. High sex ratios imply fewer married men, and marriage has been conjectured to be a socializing force. Our paper exploits the...

Goldin and Katz [2002], in an influential paper, argued that giving unmarried minors access to the contraceptive Pill was instrumental for women's professional advancement, because such access allowed marriage to be postponed. However, by 1960, married women could get the Pill and thence it is...

In 1980, housing prices in the main US cities rose with distance to the city center. By 2010, that relationship had reversed. We propose that this development can be traced to greater labor supply of high-income households through reduced tolerance for commuting. In a tract-level data set...

Crime rates almost doubled in China between 1992 and 2004. Over the same period, sex ratios (males to females) in the crime-prone ages of 16-25 years rose sharply, from 1.053 to 1.093. Although scarcity of females is commonly believed to be a source of male antisocial behavior, a causal link has...

We compare the intergenerational earnings mobility of immigrants with natives in Sweden. We find an overall convergence in average earnings between immigrants and natives. This convergence hides a divergence in average earnings between groups of immigrants with different ethnic origins. We find...

To what extent is the length of our lives determined by pre-birth factors? And to what extent is it affected by parental resources during our upbringing that can be influenced by public policy? We study the formation of adult health and mortality using data on about 21,000 adoptees born between...

We study the importance of the extended family – the dynasty – for the persistence in inequality across generations. We use data including the entire Swedish population, linking four generations. This data structure enables us to identify parents' siblings and cousins, their spouses, and the...

We use data on a large sample of Swedish-born adoptees and their biological and adopting parents to decompose the persistence in health inequality across generations into pre-birth and post-birth components. We use three sets of measures for health outcomes in the second generation: mortality,...

In this study we examine the passage of a reform to in-vitro fertilization (IVF) procedures in Sweden in 2003. Following publication of medical evidence showing that pregnancy success rates could be maintained using single rather than multiple embryo transfers, the single embryo transfer (SET)...
