Using data from the National Longitudinal Survey of Youth 1979 (NLSY79), the third chapter examines impacts of maternal employment on the development of children in families led by working single mothers. A contemporaneous specification and a value-added specification are implemented for modeling the production functions for cognitive and non-cognitive development of children. In the estimation models based on the contemporaneous specification, instrumental variables and fixed-effects models are used to identify the effects of mother's recent work hours and work weeks. No significant effects of contemporaneous maternal employment are found. The value-added specification includes a lagged outcome that represents all past inputs to the production of outcomes of children. There is little evidence of significant effects of maternal employment in any of the models estimated. |
