Three Papers in Labor Economics Ph.D. Dissertation, Michigan State University, 2002 Cohort(s): NLSY79 Publisher: UMI - University Microfilms, Bell and Howell Information and Learning Keyword(s): The first paper demonstrates that the time-allocation generalization of labor supply can generate interesting and surprising predictions regarding labor supply behavior. These predictions follow from the assumptions made about input combinations available for final consumption. When goods cannot be produced strictly from time or money then either input could curtail the substitution effect. The second paper shows that Korenman and Blackburn's (1994) finding of a ten-percentage point drop in the Male Marriage Earning Differential (MMED) over the years 1967-1988 is biased upwards. It presents evidence that the bias may be due to the imputation procedures used before 1976. Then, it uses a residual-based trimmed estimator to remove the bias and construct a more consistent MMED series. The new series supports the conclusion that both changes in selection and married female labor force participation affect the MMED. The paper concludes that, while the MMED does not appear to have changed significantly, as of the late 1980s, the composition of the MMED has become more due to selection. The third paper surveys investigations into the causality of the MMED. Gray's (1997) comparison of the returns to years of marriage with the NLS and NLSY and Stratton's (2002) estimation of the return to years of marriage and cohabitation using the NFHS are reexamined with the assistance of a residual-based trim and then compared with other longitudinal studies' findings. Then, a qualitative comparison is made of recent MMED studies' findings of the prevalent direction of causality for the MMED. There appears to be evidence that being married had an effect on earnings before 1970 and 1970-1979. However, more recent studies either support the selection hypothesis or fail to find evidence that the household division of labor enhances the husband's market productivity. Finally, a meta-analysis of cross-sectional estimates of the MMED across time and age groups is made. The meta-analysis finds a four-percentage point decline in the MMED in recent years, after controlling for how the MMED rises with age. |
