Econometric Approaches to Public Health Policy: Behavioral Response to Substance Use Regulations Ph.D. Dissertation, Department of Economics, University of California, Santa Barbara, 2014 Cohort(s): NLSY97 Publisher: ProQuest Dissertations & Theses (PQDT) Keyword(s): Alcohol Use; Drug Use; Gender Differences; Substance Use Permission to reprint the abstract has not been received from the publisher. The third chapter, entitled "The Substitutability of Alcohol and Marijuana: Where there is Smoke, is there Fire?," uses data from the 2002-2007 National Survey on Drug Use and Health to investigate recent evidence from a regression discontinuity framework that alcohol and marijuana are substitutes for young adults. The central assumption underlying this method is that the model correctly specifies the smooth function of the forcing variable, in this case, age. I consider a wide variety of parametric and nonparametric models to test the robustness of the discontinuous effect found for marijuana use at the minimum legal drinking age (MLDA). The recent finding that alcohol and marijuana are substitutes is sensitive to specification choice for the whole sample. Regardless of the specification there is no evidence of a significant change in marijuana use by men, while the substitution effect for women is robust. I corroborate and investigate the gender difference using data from the National Longitudinal Survey of Youth 1997 Cohort (NLSY97). I find that the reduction in marijuana use at the MLDA by women is heterogeneous by education and race. There is also evidence of a complementary relationship between alcohol and marijuana use for parts of the male sample. |

Maternal Employment and Academic Achievement: An Empirical Project Masters Thesis, Applied Economics, University of North Carolina at Greensboro, May 2006. Also: http://www.uweb.ucsb.edu/~kwelding/documents/kevin_final_draft.doc Cohort(s): Children of the NLSY79 Publisher: Department of Economics, University of North Carolina at Greensboro Keyword(s): Maternal Employment; Peabody Individual Achievement Test (PIAT- Math); Peabody Individual Achievement Test (PIAT- Reading); Peabody Picture Vocabulary Test (PPVT); Socioeconomic Status (SES) Permission to reprint the abstract has not been received from the publisher. This paper uses the NLSY79 to link mothers to their children and exploit detailed information on child, mother and household characteristics, as well as supplemental area, paternal and income information. Maternal employment was found to have a small, statistically insignificant effect on achievement test scores. The estimates show that maternal employment during the first five years of a child's life has a negative effect on achievement test scores and recent maternal employment has a positive effect, but both estimates are statistically insignificant. The results do not show a significant difference in effects of maternal employment for daughters and sons. The most compelling results occur when maternal employment effects are examined for advantaged and disadvantaged children separately. The estimates provide evidence of neutral and harmful effects of maternal employment for children in higher SES families and neutral and beneficial effects for children in lower SES families. |
