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.     

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.     

Kindergarten skills and fifth-grade achievement: Evidence from the ECLS-K

Children enter kindergarten with disparate rudimentary reading and mathematics skills; capabilities for paying attention, sitting still and making friends; mental health; and inclinations for aggressive behavior. The role of these characteristics in producing fifth-grade school achievement is the subject of this paper. We find considerable impacts for school-entry academic skills but, with the exception of a kindergartener's capacity to pay attention, virtually no impacts for the collection of socioemotional skills. This finding holds both for the overall sample and for subgroups defined by race/ethnicity and socioeconomic status. The most powerful pre-school avenue for boosting fifth-grade achievement appears to be improving the basic academic skills of low-achieving children prior to kindergarten entry.     

Conditional cash penalties in education: Evidence from the Learnfare experiment

Wisconsin's influential Learnfare initiative is a conditional cash penalty program that sanctions a family's welfare grant when covered teens fail to meet school attendance targets. In the presence of reference-dependent preferences, Learnfare provides uniquely powerful financial incentives for student performance. However, a 10-county random-assignment evaluation suggested that Learnfare had no sustained effects on school enrollment and attendance. This study evaluates the data from this randomized field experiment. In Milwaukee County, the Learnfare procedures were poorly implemented and the random-assignment process failed to produce balanced baseline traits. However, in the nine remaining counties, Learnfare increased school enrollment by 3.5 percent (effect size = 0.08) and attendance by 4.5 percent (effect size = 0.10). These results suggest that well-designed financial incentives may be an effective mechanism for improving the school persistence of at-risk students at scale.     

Peer effects on high school aspirations: Evidence from a sample of close and not-so-close friends

In this paper we investigate how schoolmates influence high school dropout intentions in Catalonia, Spain. Our analysis uses self-reported friends to identify possible peers by assuming that peer influence flows in one direction in cases where one student identifies another as a friend, but the other does not reciprocate. We first estimate the effects of education aspirations of non-reciprocating friends on students’ own education aspirations, with and without conditioning on a large set of personality and cognitive characteristics. We then investigate the extent to which the estimated effects are associated with friends’ height, weight, BMI, gender and cognitive ability. The estimated impact of non-reciprocating peers’ dropout intentions is small and generally not statistically significant: a 10 percentage point increase in the fraction of non-reciprocating peers that intend to drop out increases students’ chances of dropping out by about .2 percentage points.     

Risk and career choice: Evidence from Turkey

In this paper, we examine the college major choice decision in a risk and return framework using university entrance exam data from Turkey. Specifically we focus on the choice between majors with low income risk such as education and health and others with riskier income streams. We use a unique dataset that allows us to control for the choice set of students and parental attitudes towards risk. Our results show that father's income, self-employment status and social security status are important factors influencing an individual in choosing a riskier career such as business over a less risky one such as education or health.     

Forward-Thinking Teens: The Effects of College Costs on Adolescent Risky Behavior

This paper analyzes the effect of college costs on teenagers’ engagement in risky behaviors before they are old enough to attend college. Individuals with brighter prospects for future schooling attainment may engage in less drug and alcohol use and risky sexual activity because they have more to lose if such behaviors have harmful effects in their lives. If teens correctly predict that higher college costs make future college enrollment less likely, then adolescents facing different expected costs may choose different levels of risky behavior. I find that lower college costs in teenagers’ states of residence raise their subjective expectations regarding college attendance and deter teenage substance use and sexual partnership. Specifically, a $1,000 reduction in tuition and fees at 2-year colleges in a youth's state of residence (roughly a 50% difference at the mean) is associated with a decline in the number of sexual partners the youth had in the past year (by 26%), the number of days in the past month the youth smoked (by 14%), and the number of days in the past month the youth used marijuana (by 23%). These findings suggest that the often-studied correlation between schooling and health habits emerges in adolescence because teenagers with brighter college prospects curb their risky behavior in accordance with their expectations. The results also imply that policies that improve teenagers’ educational prospects may be effective tools for reducing youthful involvement in such behaviors.     

Non-market effects of education on crime: Evidence from Italian regions

This paper studies the non-market effects of education on crime using a panel dataset for the 20 Italian regions over the period 1980–1995. Our empirical results suggest that education reduces crime over and above its effect through labour market opportunities (employment rate and wage rate). Because of the absence of a credible instrumental variable for education for Italy, our empirical strategy is to include in our econometric specification region fixed effect, year fixed effects and region-specific time trends together with an extensive set of socioeconomic and deterrence variables. Our results are robust to model specification, changes in the typology of crimes and finally, to alternative definitions of education.     

Prestige,charitable deductions and other determinants of alumni giving: Evidence from a highly selective liberal arts college

Private institutions of higher education are highly dependent on alumni support to cover operating expenses, fund endowments and fuel large capital campaigns. For example, in 2004, alumni at private liberal arts colleges generated nearly 43% of total voluntary support and funded 21.5% of total institutional expenditures. This paper uses 15 years of detailed data on alumni donations to a private liberal arts college to explore a full range of potential determinants of giving. Results suggest that wealthy alumni who live in states that allow charitable tax deductions are more generous than otherwise similar alumni in states without such subsidies. Alumni contributions also increase in years when the college has achieved greater athletic prestige but fall when academic prestige rises. Furthermore, recent alumni are more influenced by institutional prestige than older graduates. With regard to other determinants, females tend to be more generous, as do alumni living in wealthier neighborhoods within 250 miles of the college. Alumni who have close alumni relatives tend to give more as do alumni who participated in campus activities during their college years. Undergraduate major and occupational sector are also strong predictors of giving behavior.     

The impact of education on health knowledge

The theory on the demand for health suggests that schooling causes health because schooling increases the efficiency of health production. Alternatively, the allocative efficiency hypothesis argues that schooling alters the input mix chosen to produce health. This suggests that the more educated have more knowledge about the health production function and they have more health knowledge. This paper uses data from the 1997 and 2002 waves of the NLSY97 to conduct an investigation of the allocative efficiency hypothesis by analyzing whether education improves health knowledge. The survey design allows us to observe the increase in health knowledge of young adults after their level of schooling is increased by differential and plausibly exogenous amounts. Using nine different questions measuring health knowledge, we find weak evidence that an increase in education generates an improvement in health knowledge for those who ultimately attend college. For those with high school as the terminal degree, no relationship is found between education and health knowledge. These results imply that the allocative efficiency hypothesis may not be the primary reason for why schooling impacts health outcomes.     

Immigration and student achievement: Evidence from Switzerland

This paper investigates empirically whether immigrant students in Switzerland perform poorly compared to their native counterparts and provides some explanations. Using a national sample of the 2000 PISA (Programme for International Student Assessment) database, we first analyze the impact of immigrant status on pupils’ achievement. We find a negative and significant impact of immigrant status on test scores in reading, mathematics and science literacy, even after controlling for a set of characteristics. We then decompose the observed reading score gap between Swiss and immigrant students to identify whether gaps in endowments explain test score differences along the distribution. Lower endowments explain most of the achievement gap in reading between Swiss and second-generation immigrants. However, lower returns explain around one quarter of the achievement gap between Swiss and first-generation immigrants for the weakest pupils.     

The effect of social programs and exposure to professionals on the educational aspirations of the poor

Investment in human capital is an important tool for reducing poverty. However, the poor may lack the capacity to aspire, which often results in underinvestment in their children's education. This paper studies the effect of a social program on the educational aspirations poor parents have for their children, and explores the role of exposure to educated professionals as a possible channel for increasing these aspirations. First, using differences-in-differences, we show that the Mexican antipoverty program PROGRESA raises the educational aspirations of beneficiary parents for their children of a third of a school year. Then, exploiting PROGRESA's mandated differential exposure to professionals, using triple differences, we find evidence suggesting that educational aspirations for children from high-exposure households are almost half of a school year higher six months after the start of the program. Finally, we show that there is a positive correlation between parental aspirations and children's educational attainment.     

The causal effect of education on health: Evidence from the United Kingdom

Numerous economic studies have shown a strong positive correlation between health and years of schooling. The question at the centre of this research is whether the correlation between health and education represents a causal relation. This paper uses changes in compulsory schooling laws in the United Kingdom to test this hypothesis. Multiple measures of overall health are used. The results provide evidence of a causal relation running from more schooling to better health which is much larger than standard regression estimates suggest.     

The adverse effects of parents’ school selection errors on academic achievement: Evidence from the Beijing open enrollment program

One major concern with public school open enrollment programs is the potential for parents’ school selection errors to adversely affect their children's academic achievement. In this study of the Beijing middle school open enrollment program, we estimate the degree to which children's school outcomes were negatively affected by the poor choices their parents made during the school selection process. We do this by examining parents’ responses to a survey on school choices combined with actual school applications, school admission records, and High School Entrance Examination test scores for 4717 students entering middle schools in Beijing via randomized lotteries. We find that the children of parents who made judgment errors in school selection were admitted to lower quality schools and achieved lower test scores on the High School Entrance Examination. Parents who had less education, whose children performed at lower levels in primary school, and who were less attentive to teachers’ opinions about schools were more prone to make these errors. Providing assistance to parents, especially those less prepared to make informed choices about school selection, is consequently important for supporting more efficient and equitable open enrollment programs.     

Non-formal basic education as a development priority: Evidence from Nicaragua

Almost 900m adolescents and adults are illiterate in the developing world, yet most policy discussions focus on the educational circumstances of primary aged children. As a result non-formal educational programs for adolescents and adults are given very little support, and this group is virtually ignored in international agreements such as the millennium declaration. This article presents the first serious attempt at evaluating the impact of a non-formal education program. Results show significant learning achievement over the academic year, as well as strong development impacts of the program in non-learning dimensions of participants’ lives. These positive impacts, plus the significantly lower unit costs and self-targeted nature of the program provide strong evidence that this type of program can be an important part of the poverty reduction and human capital enhancement strategy of developing countries with large illiterate adult populations.

Taking the maker movement to school: A systematic review of preK-12 school-based makerspace research

In this systematic review, we examined research on school-based makerspaces, emergent but increasingly popular sites for instruction and learning in preK through 12 settings. Through electronic database, hand, and ancestral searches, we identified 22 empirical studies published in peer-reviewed journals and dissertations that reported preK-12 students’ learning outcomes after participating in school-based makerspace interventions. We found that school-based makerspace research is increasing and published internationally, with a majority of studies (n = 13) conducted with middle and high school participants. Outcomes and interventions varied considerably across studies, demonstrating the disparate nature of school-based makerspace research. In the studies we reviewed, the goals, objectives, and scope of makerspace interventions did not conflict with those of schools, but best practices for makerspace teachers were lacking and equity-oriented approaches to designing makerspace activities and materials were still emerging. Implications of our findings for planning makerspace instruction and future research on makerspace interventions are discussed.     

The effect of kindergarten classroom size reduction on second grade student achievement: Evidence from California

Because classroom size reduction (CSR) and standards based testing were implemented at the same time in California during the mid-1990s, it is difficult to isolate the effects of classroom size on outcomes from the effects of curriculum changes. As a result, the main comparison in this paper is very specific – the effect of reduced sized kindergarten classrooms on test performance in second grade. The main result of the paper is that the effect of classroom size reduction is small, especially when compared to the other determinants of student achievement at the second grade level. There is a very small effect of classroom size reduction on student achievement in reading and math, and no effect in language and spelling. Of the two offsetting effects of CSR controlling for spending – the direct effect of smaller classes and the indirect effect on teacher quality, the class-size effect is larger. Over time, the negative effect on teacher quality is reduced as new teachers gain experience and credentials.
