Essays on Recovering Latent Characteristics Using Nonparametric and Semiparametric Methods Ph.D. Dissertation, Department of Economics, Johns Hopkins University, 2016 Cohort(s): NLSY97 Publisher: Johns Hopkins University Keyword(s): Drug Use; Modeling; Self-Reporting Permission to reprint the abstract has not been received from the publisher. This dissertation explores applying nonparametric and semiparametric methods to recover latent characteristics in various settings. The second chapter employs panel data to recover latent behavior related to the health and drug use of survey respondents. The misreporting problem of drug use in self-reported surveys can severely affect the validity of estimation results in empirical work. In this paper we use an eigen-decomposition method to nonparametrically estimate the misclassification errors under various assumptions and settings. We use the longitudinal data of NLSY97 and focus on the years from 2005 to 2009, when the cohort is aged in their mid-20s. We find that the overall proportion of participants who actually use marijuana is higher than the reported proportion. Moreover, participants' inclination to misreport their drug use status is related to their current and previous actual drug use as well as their "habit" for misreporting in surveys. In general, males are more likely to underreport their drug use than females. |

Essays on Higher Education and Human Capital Investments Ph.D. Dissertation, Department of Economics, Johns Hopkins University, 2019 Cohort(s): NLSY79 Young Adult Publisher: Johns Hopkins University Keyword(s): College Characteristics Permission to reprint the abstract has not been received from the publisher. In the third chapter, `"Why Not Choose the Best School? The Determinants of College Choices", I study the determinants of college choices among the schools offering admission. There is extensive research literature on the determinants of mismatch between student ability and college quality that focuses mostly on how students make application decisions. However, the college decision process consists of several stages and includes students' decision-making processes when deciding on which school's admissions offer to accept. This study uses the National Longitudinal Survey of Youth 1979 Children and Young Adults data to examine how students choose colleges among the schools offering admission. The analysis shows that while most students choose schools with the highest quality among the available offers, about 40% of students do not. Students' demographic and socioeconomic backgrounds do not explain such enrollment pattern well. College characteristics in relation to students' characteristics--the degree of overmatch (low ability students at high quality colleges) and the distance to college--affect college choice. |
