An Odd Couple: Monotone Instrumental Variables and Binary Treatments Econometric Reviews 35,6 (2016): 1099-1110. Also: http://tandfonline.com/doi/abs/10.1080/07474938.2014.977082 Cohort(s): NLSY97 Publisher: Taylor & Francis Group Keyword(s): Crime; Modeling, Instrumental Variables; Occupations; Treatment Response: Monotone, Semimonotone, or Concave-monotone Permission to reprint the abstract has not been received from the publisher. This paper investigates Monotone Instrumental Variables (MIV) and their ability to aid in identifying treatment effects when the treatment is binary in a nonparametric bounding framework. I show that an MIV can only aid in identification beyond that of a Monotone Treatment Selection assumption if for some region of the instrument the observed conditional-on-received-treatment outcomes exhibit monotonicity in the instrument in the opposite direction as that assumed by the MIV in a Simpson's Paradox-like fashion. Furthermore, an MIV can only aid in identification beyond that of a Monotone Treatment Response assumption if for some region of the instrument either the above Simpson's Paradox-like relationship exists or the instrument's indirect effect on the outcome (as through its influence on treatment selection) is the opposite of its direct effect as assumed by the MIV. The implications of the main findings for empirical work are discussed and the results are highlighted with an application investigating the effect of criminal convictions on job match quality using data from the 1997 National Longitudinal Survey of the Youth. Though the main results are shown to hold only for the binary treatment case in general, they are shown to have important implications for the multi-valued treatment case as well. |

Essays on the Identification of Treatment Effects with Applications to the Labor Market Ph.D. Dissertation, Iowa State University, 2012 Cohort(s): NLSY97 Publisher: ProQuest Dissertations & Theses (PQDT) Keyword(s): Crime; Criminal Justice System; Labor Market Outcomes Permission to reprint the abstract has not been received from the publisher. This dissertation contains three independent essays; each essay can be read in isolation. The first essay investigates the causal effect of criminal convictions on various labor market outcomes in young adults. The estimation method used is a nonparametric bounding approach intended to partially identify the causal effect. The data used for this essay comes from the 1997 National Longitudinal Survey of the Youth. The second essay reevaluates the causal effect of post-secondary schooling on unemployment incidence using historical data from the 1980 U.S. Census and information on cohort level Vietnam War conscription risk. Conscription risk is used as an instrument for endogenous post-secondary schooling in a specification that accounts for the discrete nature of the treatment and outcome of interest. The third essay investigates the underlying necessary assumptions needed for the monotone instrumental variable (MIV) assumption to have identifying power on both the upper and lower bounds of a treatment effect when the treatment of interest is binary. I show that if the treatment is monotonic in the instrument, as is routinely assumed in the literature on instrumental variables, then for the MIV to have identifying power on both the lower and upper bounds of the treatment effect, the conditional-on-received-treatment outcomes cannot exhibit the same monotonicity assumed by the MIV. Results are highlighted with an application investigating the effect of criminal convictions on job match quality using data from the 1997 National Longitudinal Survey of the Youth. |

Heterogeneous Trends in U.S. Teacher Quality 1980-2010 Education Economics 23,6 (November 2015): 645-659. Also: http://www.tandfonline.com/doi/abs/10.1080/09645292.2014.996120 Cohort(s): NLSY79, NLSY97 Publisher: Carfax Publishing Company ==> Taylor & Francis Keyword(s): Armed Forces Qualifications Test (AFQT); Cognitive Ability; Heterogeneity; Occupations Permission to reprint the abstract has not been received from the publisher. This paper documents changes in the entire ability distribution of individuals entering the teaching profession using the 1979 and 1997 cohorts of the National Longitudinal Survey of Youth and a constructed Armed Force Qualifying Test score that allows direct comparison of ability between cohorts. Such direct comparison between cohorts was previously not possible due to a lack of directly comparable measures of ability. I find there are minimal differences in the ability distribution between cohorts. However, this similarity masks vast differences within specific demographics. I then also decompose these changes into cohort-wide shifts and within-cohort shifts of teachers. |

Shackled Labor Markets: Bounding the Causal Effects of Criminal Convictions in the U.S. International Review of Law and Economics 41 (March 2015): 17-24. Also: http://www.sciencedirect.com/science/article/pii/S014481881400074X Cohort(s): NLSY97 Publisher: Elsevier Keyword(s): Crime; Earnings; Incarceration/Jail; Labor Economics; Labor Market Outcomes; Racial Differences This paper examines the causal effects of criminal convictions on labor market outcomes in young men using U.S. data from the National Longitudinal Survey of Youth 1997 cohort. Unlike previous research in this area which relies on assumptions strong enough to obtain point identification, this paper imposes relatively weak nonparametric assumptions that provide tight bounds on treatment effects. Even in the absence of a parametric model, under certain specifications, a zero effect can be ruled out, though after a bias correction this result is lost. In general the results for the effect on yearly earnings align well with previous findings, though the estimated effect on weeks worked are smaller than in previous findings which focused on the effects of incarceration. The bounds here indicate the penalty from convictions, but not incarceration, lowers weeks worked by at most 1.55 weeks for white men and at most 4 weeks for black men. Interestingly, when those ever incarcerated are removed from the treatment group for black men, there does not appear to be any effect of convictions on earnings or wages but only on weeks worked. |

The Effect of Youth Labor Market Experience on Adult Earnings Journal of Economic Development 39,1 (March 2014): 47-61. Also: http://www.jed.or.kr/full-text/39-1/2.pdf Cohort(s): NLSY97 Publisher: The Economic Research Institute of Chung-Ang University (Korea) Keyword(s): Earnings; Employment, Youth; Labor Force Participation Permission to reprint the abstract has not been received from the publisher. This paper investigates the effect of multiple youth jobs on adult earnings using the 1997 National Longitudinal Survey of Youth along with multiple regression specifications to identify treatment effects and a set of relatively weak nonparametric assumptions that provide tight bounds on treatment effects. Various specifications under an exogenous selection assumption indicate that an additional youth job increases adult yearly income by about $600 with the effect on men being larger than the effect on women. These specifications control for the number of adult jobs as well as the number of weeks worked as a youth. The partial identification strategy bounds the effect for men to be greater than zero, yet substantially smaller than the regression results. However, the confidence intervals on these estimates do not exclude a zero effect. Though a spurious explanation cannot be completely ruled out by the analysis, the results in this paper seem to imply that working multiple jobs as a youth has positive effects on adult earnings beyond pure labor market experience in contrast to the negative effect of multiple jobs as an adult. |

Changing Roles of Ability and Education in U.S. Intergenerational Mobility Economic Inquiry 55,1 (January 2017): 187-201. Also: http://onlinelibrary.wiley.com/doi/10.1111/ecin.12362/abstract Cohort(s): NLSY79, NLSY97 Publisher: Wiley Online Keyword(s): Armed Forces Qualifications Test (AFQT); Armed Services Vocational Aptitude Battery (ASVAB); Educational Attainment; Gender Differences; Intergenerational Patterns/Transmission; Mobility, Economic; Parental Influences; Socioeconomic Background Permission to reprint the abstract has not been received from the publisher. Using data on young adults from the 1979 and 1997 National Longitudinal Survey of Youth, we investigate the changing roles of ability and education in the transmission of economic status across generations. We find that ability plays a substantially diminished role for the most recent cohort whereas education plays a much larger role. The first finding results primarily from a smaller effect of children's ability on status, the second from an increased correlation between parental status and educational attainment. A replication of the analysis by gender reveals that the changes in the role of ability are largely driven by men whereas the changes in education's role are largely driven by women. |

Decomposing Economic Mobility Transition Matrices Journal of Applied Econometrics 33,1 (January/February 2018): 91-108. Also: http://onlinelibrary.wiley.com/doi/10.1002/jae.2578/abstract Cohort(s): NLSY79 Publisher: Wiley Online Keyword(s): Family Income; Geocoded Data; Income Distribution; Intergenerational Patterns/Transmission; Mobility, Economic; Parental Influences Permission to reprint the abstract has not been received from the publisher. We present a decomposition method for transition matrices to identify forces driving the persistence of economic status across generations. The method decomposes differences between an estimated transition matrix and a benchmark transition matrix into portions attributable to differences in characteristics between individuals from different households (a composition effect) and portions attributable to differing returns to these characteristics (a structure effect). A detailed decomposition based on copula theory further decomposes the composition effect into portions attributable to specific characteristics and their interactions. To examine potential drivers of economic persistence in the USA, we apply the method to white males from the 1979 US National Longitudinal Survey of Youth. Depending on the transition matrix entry of interest, differing characteristics between sons from different households explain between 40% and 70% of observed income persistence, with differing returns for these characteristics explaining the remaining gap. Further, detailed decompositions reveal significant heterogeneity in the role played by specific characteristics (e.g., education) across the income distribution. |
