Small Family, Smart Family? Family Size and the IQ Scores of Young Men
Black, Sandra E.; Devereux, Paul J.; Salvanes, Kjell G.
Journal of Human Resources, v45 n1 p33-58 Win 2010
This paper uses Norwegian data to estimate the effect of family size on IQ scores of men. Instrumental variables (IV) estimates using sex composition as an instrument show no significant negative effect of family size; however, IV estimates using twins imply that family size has a negative effect on IQ scores. Our results suggest that the effect of family size depends on the type of family-size intervention and that there are no important negative effects of "expected" increases in family size. However, unexpected shocks to family size resulting from twin births have negative effects on the IQ scores of existing children. (Contains 26 footnotes, 6 tables, and 3 figures.)
