Most studies only look at the effect on income, and in the US or Chile.  \n● The formal evidence mostly points to small effects (0-10%)– but we’re not confident in the methods they used. So it comes down to your prior about elite schooling. You can find a web app which allows you to apply your own judgment here.  \n● One measure of school quality (or selectiveness!) is the average SAT score of students who enroll. +200 points represents a large jump in school rank (hundreds of ranks).  \n● Applying our prior, using average intake SAT as a school quality proxy, we think:  \n\n| Claim | Intervention | Operationally | Confidence |\n| --- | --- | --- | --- |\n| Income boost small ( \u003C = 10%) | Average to good school | 1150 → 1350 SAT | 75% |\n| Income boost small ( \u003C = 10%) | Good to very good | 1250 → 1450 SAT | 65% |\n| Income boost medium\u003Cbr>( \u003C = 25%) | Good to top 10 | 1300 → 1500 SAT | 60% |\n\n● Most of the evidence is about US students at US colleges; we are even less confident outside this domain. There is some evidence that effects are larger for ethnic minority students and very mixed for female students.  \n● This report represents 1.9 weeks of effort.  \nWhy even ask this question?  \nThere’s a lot of emphasis on elite higher education—whether that’s ambitious applicants deciding where to apply to increase their impact, or funders thinking about what scholarships to offer. Economists are, surprisingly, less clear on the benefits.  \nOn the surface, this is an odd thing to doubt. The ‘effect’ hits you between the eyes:  \nBut this is a paradigm example of observational data misleading us: for instance, getting into an elite college correlates heavily with your talent, and talent correlates heavily with your earnings. (And this is just one confounder among many—consider also social class.)  \n✱ = the effect of going to an elite college, given you’re the kind of person who got in  \nSo, our research question  \nWhat’s the causal effect of attending an elite college instead of a good college, particularly for the strongest students?1  \nWe’re interested in the effect of elite schools on subsequent social impact, but we can’t see any studies on this. So we use any form of subsequent success as a proxy for added impact.(90% of studies use earnings as the outcome of interest.)  \nWhy expect income to be a decent proxy for impact? Because some things about college cause both income and impact: e.g. knowledge, peer connections, first-job prestige and career tracks, or self-efficacy.  \nIncome reflects your competence. Impact also reflects competence, and so if college affects competence then it should affect impact.  \nWe demand causal identification, that the study be able to factor out unobserved confounders. This leads us to throw out most studies, because they just use ordinary regression plus covariates to “control” for obvious variation. This means they can’t guarantee fully isolating the added value of attendance from the existing potential of admitted students (“ability bias” or “positive selection bias”).2 Briefly though: OLS studies find 10-30% increased earnings from elite college.  \nSo: we want regression discontinuity designs ( RDDs), twin studies, and (with some qualifications) instrumental variable and matched-applicant designs. (We briefly explain these methods in Appendix A.) But we should remember that all of these are essentially observational studies, underneath the clever tricks which may somewhat reduce bias.  \n1 Note that our question is very different from the average private return to education in general (i.e. pre-college schooling) , which seems high, particularly for disadvantaged groups. It’s also different from the social return, memorably and eccentric","cbCailIXRQv2JMSh","https://ap.wps.com/l/cbCailIXRQv2JMSh","pdf",11393534,33,"English","# Executive Summary\n## Research question and causal identification\n## Initial inclusion criteria and results\n## Refining the search","[{\"question\":\"What is the report’s main research question about elite colleges?\",\"answer\":\"It asks for the causal effect of attending an elite college instead of a good college, especially for the strongest students.\"},{\"question\":\"Why does the report emphasize causal identification rather than simple correlations?\",\"answer\":\"Because observational data can mislead due to confounding such as talent and social class, which correlate with both elite admission and later earnings.\"},{\"question\":\"What do the initial results suggest about income gains from elite colleges?\",\"answer\":\"They mostly indicate small effects, with typical estimates below or around 10%, while the report notes limited confidence due to concerns about the methods used.\"}]","The Return to Top Schools - A Review of the Causal Evidence - An Arb Research Report - November 2022 | PDF",83]
