Maternity leaves can affect mothers' and infants' welfare if they first affect the amount of time working women stay at home post birth. We provide new evidence of the labor supply effects of these leaves from an analysis of the introduction and expansion of job-protected maternity leave in...

We investigate the impact of maternity leave on the cognitive and behavioral development of children at ages 4 and 5, following up previous research on these children at younger ages. The impact is identified by legislated increases in the duration of maternity leave in Canada, which...

This paper exploits a unique ongoing experiment to analyze the effects of early rearing conditions on physical and mental health in a sample of rhesus monkeys (Macaca mulatta). We analyze the health records of 231 monkeys which were randomly allocated at birth across three rearing conditions:...
