Language,high school leadership and the postsecondary outcomes of Hispanic students

This paper asks whether high school leadership activities play an important role in explaining the Hispanic college-completion gap. The analysis in this paper considers the role that English language fluency plays in a Hispanic student's leadership probability and in the student's future educational success. The main results in this paper are: first, after controlling for demographic and school characteristics, there are no major differences in high school leadership activities between Hispanics and non-Hispanics; second, high school leadership activities predict higher college attendance rates for all demographic groups; and third, high school leadership activities predict a higher probability of attaining a college degree among Hispanic students whose first language is not English. Importantly, this relationship is stronger among students whose first post-secondary institution is a 2-year college.     

The medium term schooling and health effects of low birth weight: Evidence from siblings

Research has shown that low birth weight is linked to infant mortality as well as longer term outcomes. This paper examines the medium term outcomes that may link low birth weight to adult disadvantage using a national longitudinal sample with a large sample of siblings (Add Health). Results show strong effects on several educational outcomes, including early grade repetition, receipt of special education services, and reports of a learning disability. Results for longer term outcomes are suggestive, though less robust and small in magnitude. Overall, the results suggest that medium term educational disadvantages associated with low birth weight are not driven by family level unobservables and do not accumulate into large long-term disadvantage.     

Sports participation and academic performance: Evidence from the National Longitudinal Study of Adolescent Health

It has been argued that high school sports participation increases motivation and teaches teamwork and self-discipline. While several studies have shown that students who participate in athletic activities perform better in school than those who do not, it is not clear whether this association is a result of positive academic spillovers, or due to the influence of unobservables. Using data from the National Longitudinal Study of Adolescent Health and a variety of statistical techniques designed to distinguish between these hypotheses, we examine the effect of sports participation on several measures of academic performance. Our results provide only limited evidence that sports participation leads to enhanced academic performance.     

The impact of legalized abortion on high school graduation through selection and composition

This analysis examines whether the legalization of abortion changed high school graduation rates among the children selected into birth. Unless women in all socio-economic circum-stances sought abortions to the same extent, increased use of abortion must have changed the distribution of child development inputs. I find that higher abortion ratios are associated with higher graduation rates for black males, but not other demographic groups. In a pooled analysis, I find that abortion has a significant negative impact on graduation rates. The effect disappears when I control for ethnicity. The cohorts born between 1965 and 1979 contained falling shares of whites, who have relatively high graduation rates. Regression results indicate abortion ratios are linked with the fertility differences between ethnicities, which suggests this is a channel of influence. Overall, the relationship between abortion exposure and educational attainment is small. A standard deviation change in abortion might move the national graduation rate by less than three-tenths of a percentage point.     

Does school choice increase the rate of youth entrepreneurship?

Because entrepreneurial activity is a key source of economic growth, promoting youth entrepreneurship has become a priority for policymakers. School choice programs force administrators and teachers to be more entrepreneurial in their jobs by encouraging innovation and by creating competition and a more business-like environment in K-12 education. Does going to school in this climate make students more likely to become entrepreneurs? In this paper we test whether youth entrepreneurship rates are higher in counties with school choice programs. We find that voucher programs create higher rates of youth entrepreneurship, while charter schools do not, relative to traditional public schools.     

The impact of short-term economic fluctuations on kindergarten enrollment

For some 5-year-olds, delayed kindergarten enrollment may result in long-term academic benefits. Although waiting an additional year allows for further development prior to the start of formal education, the economic costs of the next best alternatives can be significant. This study examines the impact of short-term economic fluctuations on a household's kindergarten enrollment decision. I find that during economic downturns kindergarten enrollment increases. To explore a potential mechanism through which this effect may arise, I propose an instrumental variables approach to identify the causal effect of fluctuations in household resources due to the business cycle on the timing of kindergarten enrollment.     

Testing implications of a tournament model of school district salary schedules

Using panel data on the salary schedules of public school teachers and administrators, I look for evidence of a tournament wage structure. A tournament model is presented, where teachers compete for promotion to administrators. Districts can create incentives for teachers by offering either a higher pay premium for promotion or a larger probability of promotion. The model predicts an inverse relationship between these two values. Evidence supporting this prediction is found in the data. In contrast, an alternative model of incentive pay, where returns to seniority substitute for imperfect monitoring, is not supported empirically. This result is consistent with intuition that tenure protections make it hard for districts to fire shirking teachers, making returns to seniority a poor method of providing incentives.     

The effects of quarter of birth on academic outcomes at the elementary school level

This paper uses public schools data to examine the effects of age on student academic achievement in light of recent trends to delay children's entry into kindergarten. To avoid problems of endogeneity, students’ quarters of birth is employed as an instrument for age at entry. In particular, the effects of students’ quarters of birth on math and reading standardized test scores and grade retention at the elementary school level are estimated. Evidence of benefits to being among the oldest in one's age-grade cohort is found. Interestingly, over time, the youngest students begin to perform approximately on par with the oldest students, creating a u-shaped pattern to the data.     

The effects of high school math curriculum on college attendance: Evidence from the NLSY97

Using a sample of youth who graduated from high school in the late 1990s and early 2000s, this paper examines the impact of high school math curriculum on the decision to go to college. Results that control for unobserved differences between students and their families suggest that a more rigorous high school math curriculum is associated with a higher probability of attending college and of attending a 4-year college. The household fixed effect results imply that students who take an advanced academic math curriculum in high school (algebra II or precalculus, trigonometry, or calculus) are about 17 percentage points more likely to go to college and 20 percentage points more likely to start college at a 4-year school by age 21 compared to those students whose highest math class was algebra I or geometry.

Teens’ alcohol consumption and schooling

While research outside economics has found that drinking has a negative effect on cognitive skills, some economists have failed to find any negative relationship between drinking and academic performance. This paper argues that the reason for this discrepancy is due to the way education is measured in the economic literature. Herein, binge drinking in the senior year of high school is found to reduce the probability of receiving a high school diploma and to increase the probability of graduating with a General Education Development (GED). Moreover, this study finds that alcohol policies do not affect the dropout rate measured at the age of 25, but they do affect the probability that a student will graduate on time. In conclusion, bingeing is found to be responsible for inducing individuals to temporarily drop out of school. Eventually, these individuals return to school to complete their education, most likely by obtaining a GED diploma.     

Charter school authorizers and student achievement

In this paper we analyze the relationship between charter school authorizers and student achievement. We perform this analysis using a 10-year panel dataset from Minnesota, a state that permits four distinct types of authorizers—local school boards, postsecondary institutions, nonprofit organizations, and the Minnesota Department of Education. The results of the analysis indicate that there is no statistically significant relationship between charter school authorizing type and mean levels of student achievement. However, the analysis also reveals that schools authorized by nonprofit organizations exhibit substantially more variability in achievement than schools authorized by local school boards.

Does schooling affect health behavior? Evidence from the educational expansion in Western Germany

During the postwar period German states pursued policies to increase the share of young Germans obtaining a university entrance diploma (Abitur) by building more academic track schools, but the timing of educational expansion differed between states. This creates exogenous variation in the availability of upper secondary schooling, which allows estimating the causal effect of education on health behaviors. Using the number of academic track schools in a state as an instrumental variable for years of schooling, we investigate the causal effect of schooling on health behavior such as smoking and related outcomes such as obesity. We find large and robust negative effects of education on smoking for women. These effects can mostly be attributed to reductions in starting rates rather than increases in quitting rates. We also find large negative effects of education on smoking for men. However, the precision of these is not robust to sample specification changes and results for men should thus be interpreted with caution. We find no causal effect of education on reduced overweight and obesity.     

Educational gaps in medical care and health behavior: Evidence from US Natality data

The US Natality files provide information on medical procedures and health related behavior during pregnancy and childbirth. The data set represents nearly the universe of mothers who give birth in the US, providing the most complete coverage possible of medical care and health behavior among a specific patient population. We document gaps in outcomes by education of the mother and the changes in these educational gaps during 1989-2002.

Early commitment on financial aid and college decision making of poor students: Evidence from a randomized evaluation in rural China

Many educational systems have struggled with the question about how best to give out financial aid. In particular, if students do not know the amount of financial aid that they can receive before they make a decision about where to go to college and what major to study, it may distort their decision. This study utilizes an experiment (implemented by the authors as a Randomized Control Trial) to analyze whether or not an alternative way of providing financial aid—by providing an early commitment on financial aid during the student's senior year of high school instead of after entering college—affects the college decision making of poor students in rural China. We find that if early commitments are made early enough; and they are large enough, students will make less distorting college decisions.
