This paper examines whether there is a counter-cyclical pattern in the quality of children. In particular, we study the relationship between the unemployment rate and several measures of parental characteristics, parental behavior behavior, and child health. Using data from the Natality files, including panel level data of mothers, we find evidence of positive, counter-cyclical variation in bab...

BIRTH WEIGHT AND DURATION OF GESTATION That mean birth weight is higher for males than for females has been consistently recorded (for example by Pearson, 1900; Murray, 1924; Martin, 1931; Bakwin and Bakwin, 1934; Anderson, Brown, and Lyon, 1943), and more recently by Karn and Penrose (1951), Norval, Kennedy, and Berkson (1951), and Salber and Bradshaw (1951). There have been fewer investigatio...

This research seeks to reevaluate the relationship between AFDC and fertility by focusing on births to women through the age of twenty-three using data from the National Longitudinal Survey of Youth (NLSY). Using discrete time hazard models, I examine the impact of AFDC on births directly associated with AFDC, on out-of-wedlock births, and on all births. I also examine the importance of AFDC on...
