Abstract: Unilateral Divorce Laws (UDLs) allow people to obtain divorce without the consent of their spouse. Using the staggered introduction of UDLs across European countries, we show that households exposed to UDLs for a longer period of time accumulate more savings. This effect holds for both financial and total wealth and is stronger at higher quantiles of the wealth distribution. Consistent with a precautionary motive for savings, we also find that exposure to UDLs increases female labour supply, numeracy, trust in others and dispositional optimism.

Abstract: The spread of high-speed Internet epitomizes the digital revolution, affecting several as- pects of our life. Using German panel data, we test whether the availability of broadband Internet influences fertility choices in a low-fertility setting, which is well-known for the dif- ficulty to combine work and family life. We exploit a strategy devised by Falck et al. (2014) to obtain causal estimates of the impact of broadband Internet on fertility. We find positive effects of high-speed Internet availability on the fertility of high-educated women aged 25 and above. We further confirm this result using county-level data on total fertility rate. We show that broadband access significantly increases the share of women reporting teleworking or part-time working. Furthermore, we find positive effects on time spent with children and overall life satisfaction. Our findings are consistent with the hypothesis that high-speed Inter- net allows high-educated women to conciliate career and motherhood, which may promote fertility with a “digital divide”.

Abstract: There is a growing concern that the widespread use of computers, mobile phones and other digital devices before bedtime disrupts our sleep with detrimental effects on our health and cognitive performance. High-speed Internet promotes the use of electronic devices, video games and Internet addiction (e.g., online games and cyberloafing). Exposure to artificial light from tablets and PCs can alterate individuals' sleep patterns. However, there is little empirical evidence on the causal relationship between technology use near bedtime and sleep. This paper studies the causal effects of access to high-speed Internet on sleep. We first show that playing video games, using PC or smartphones, watching TV or movies are correlated with shorter sleep duration. Second, we exploit historical differences in pre-existing telephone infrastructure that affected the deployment of high-speed Internet across Germany (see Falck et al., 2014) to identify a source of plausibly exogenous variation in access to Broadband. Using this instrumental variable strategy, we find that access to high-speed Internet (DSL) access reduces sleep duration and sleep satisfaction. Results are driven by individuals who face work or family time constraints.

Abstract: It is well-known that immigrants tend to be healthier than US natives and that this advantage erodes with time spent in the US. However, we know less about the heterogeneity of these trajectories among arrival cohorts. Recent studies have shown that later arrival cohorts of immigrants have lower entry wages and experience less economic assimilation. In this paper, we investigate whether similar cohort effects can be observed in the weight assimilation of immigrants in the US. Focusing on obesity, we show that more recent immigrant cohorts arrive with higher obesity rates and experience a faster “unhealthy assimilation” in terms of weight gain.

Abstract: This paper uses retrospective micro data from eleven European countries to investigate the role of paternal retirement in explaining children's decisions to leave the parental home. To assess causality, I use a bivariate discrete-time hazard model with shared frailty and exploit over time and cross-country variation in early retirement legislation. Overall, the results indicate a positive and significant influence of paternal retirement on the probability of first nest-leaving of children residing in Southern European countries, for both sons and daughters. Focusing on Southern Europe, I find that the increase in children's nest-leaving around the time of paternal retirement does not appear to be justified by changes in parental resources. Rather, channels involving the supply of informal child care provided by grandparents or the quality of the home should be the focus of study.

Abstract: This paper extends the previous literature on the intergenerational transmission of human capital by exploiting variation in compulsory schooling reforms across nine European countries over the period 1920-1956. My empirical strategy follows an instrumental variable (IV) approach, instrumenting parental education with years of compulsory schooling. I find some evidence of a causal relationship between parents' and children's education. The magnitude of the estimated effect is large: an additional year of parental education raises the child's education by 0.44 of a year. I also find that maternal schooling is more important than paternal schooling for the academic performance of their offspring. The results are robust to several specification checks.
