This study investigates how maternal employment is related to the cognitive development and body weight of 10 and 11 year olds, controlling for a wide variety of child, mother and family characteristics. The results suggest that limited market work benefits youths who are relatively "disadvantaged" and even long hours, which occur infrequently, are unlikely to leave them much worse off. By cont...

Several indicators of men's economic status are used, including school enrollment, employment, type of labor contract, work experien...
