We investigate conditions sufficient for identification of average treatment effects using instrumental variables. First we show that the existence of valid instruments is not sufficient to identify any meaningful average treatment effect. We then establish that the combination of an instrument and a condition on the relation between the instrument and the participation status is sufficient for identification of a local average treatment effect for those who can be induced to change their participation status by changing the value of the instrument. Finally we derive the probability limit of the standard IV estimator under these conditions. It is seen to be a weighted average of local average treatment effects.

In the United States, awareness is increasing that medical care alone cannot adequately improve health overall or reduce health disparities without also addressing where and how people live. A critical mass of relevant knowledge has accumulated, documenting associations, exploring pathways and biological mechanisms, and providing a previously unavailable scientific foundation for appreciating the role of social factors in health. We review current knowledge about health effects of social (including economic) factors, knowledge gaps, and research priorities, focusing on upstream social determinants—including economic resources, education, and racial discrimination—that fundamentally shape the downstream determinants, such as behaviors, targeted by most interventions. Research priorities include measuring social factors better, monitoring social factors and health relative to policies, examining health effects of social factors across lifetimes and generations, incrementally elucidating pathways through kno...

The Social Determinants of Health: Coming of Age

Este libro describe un importante conjunto de habilidades clave que aumentan el aprendizaje mas profundo, la preparacion para la universidad y la carrera, el aprendizaje centrado en el estudiante y el pensamiento de orden superior. Estas etiquetas incluyen habilidades cognitivas y no cognitivas, como pensamiento critico, resolucion de problemas, colaboracion, comunicacion efectiva, motivacion, persistencia y aprender a aprender. Las habilidades del siglo XXI tambien incluyen creatividad, innovacion y etica que son importantes para el exito posterior y pueden desarrollarse en entornos de aprendizaje formales o informales. Este informe tambien describe como estas habilidades se relacionan entre si y con las habilidades y contenidos academicos mas tradicionales en las disciplinas clave de lectura, matematicas y ciencias. Educacion para la vida y el trabajo: Desarrollar conocimientos y habilidades transferibles en el siglo XXI resume los hallazgos de la investigacion que investiga la importancia de tales habilidades para el exito en la educacion, el trabajo y otras areas de responsabilidad adulta y que demuestra la importancia de desarrollar estas habilidades. en la educacion K-16. En este informe, se identifican caracteristicas relacionadas con el aprendizaje de estas habilidades, que incluyen desarrollo profesional docente, curriculo, evaluacion, programas extraescolares y extraescolares y centros de aprendizaje informal como exhibiciones y museos.

Teacher training, teacher quality and student achievement

We estimate the importance of teachers in Chicago public high schools using matched student‐teacher administrative data. A one standard deviation, one semester improvement in math teacher quality raises student math scores by 0.13 grade equivalents or, over 1 year, roughly one‐fifth of average yearly gains. Estimates are relatively stable over time, reasonably impervious to a variety of conditioning variables, and do not appear to be driven by classroom sorting or selective score reporting. Also, teacher quality is particularly important for lower‐ability students. Finally, traditional human capital measures—including those determining compensation—explain little of the variation in estimated quality.

Although education pays off handsomely in the United States, children from low-income families attain less education than children from more advantaged families. In this article, Cecilia Elena Rouse and Lisa Barrow investigate why family background is so strongly linked to education. The authors show that family socioeconomic status affects such educational outcomes as test scores, grade retention, and high school graduation, and that educational attainment strongly affects adult earnings. They then go on to ask why children from more advantaged families get more or better schooling than those from less advantaged families. For low-income students, greater psychological costs, the cost of forgone income (continuing in school instead of getting a job), and borrowing costs all help to explain why these students attain less education than more privileged children. And these income-related differences in costs may themselves be driven by differences in access to quality schools. As a result, U.S. public schools tend to reinforce the transmission of low socioeconomic status from parents to children. Policy interventions aimed at improving school quality for children from disadvantaged families thus have the potential to increase social mobility. Despite the considerable political attention paid to increasing school accountability, as in the No Child Left Behind Act, along with charter schools and vouchers to help the children of poor families attend private school, to date the best evidence suggests that such programs will improve student achievement only modestly. Based on the best research evidence, smaller class sizes seem to be one promising avenue for improving school quality for disadvantaged students. High teacher quality is also likely to be important. However, advantaged families, by spending more money on education outside school, can and will partly undo policy attempts to equalize school quality for poor and nonpoor children.

U.S. Elementary and Secondary Schools: Equalizing Opportunity or Replicating the Status Quo?.

In this article, we review the empirical evidence on the impact of education vouchers on student achievement and briefly discuss the evidence from other forms of school choice. The best research to date finds relatively small achievement gains for students offered education vouchers, most of which are not statistically different from zero. Furthermore, what little evidence exists regarding the potential for public schools to respond to increased competitive pressure generated by vouchers suggests that one should remain wary that large improvements would result from a more comprehensive voucher system. The evidence from other forms of school choice is also consistent with this conclusion. Many questions remain unanswered, however, including whether vouchers have longer-run impacts on outcomes such as graduation rates, college enrollment, or even future wages, and whether vouchers might nevertheless provide a cost-neutral alternative to our current system of public education provision at the elementary and ...

School Vouchers and Student Achievement: Recent Evidence, Remaining Questions

We present results from a randomized study of a well-defined use of computers in schools, a popular instructional computer program for pre-algebra and algebra. We primarily assess the program using a test designed to target pre-algebra and algebra skills. Students ran domly assigned to computer-aided instruction score significantly higher on a pre-algebra and algebra test than students randomly assigned to traditional instruction. We hypothesize that this effective ness arises from increased individualized instruction as the effects appear larger for students in larger classes and in classes with high student absentee rates.
