Tracking can be more equitable than mixing: peer effects and college attendance.

Parents and policy makers often wonder whether, and how, the choice between a tracked or a mixed educational system affects the efficiency and equity of national educational outcomes. This paper analyzes this question taking into account their impact on educational results at later stages and two main results are found. First, it shows that tracking can be the efficient system in societies where the opportunity cost of college attendance is high or the pre-school achievement distribution is very dispersed. Second, this paper shows that although conventional wisdom suggests that equality of opportunities is best guaranteed under mixing, this is not necessarily the case. In fact, tracking is the most equitable system for students with intermediate levels of human capital required to attend college..Peer Effects, Tracking, Mixing, College attendance gap.

On the optimal allocation of students when peer effect works: Tracking vs Mixing

The belief that both the behavior and outcomes of students are affected by their peers is important in shaping education policy. I analyze two polar education systems -tracking and mixing- and propose several criteria for their comparison. I find that tracking is the system that maximizes average human capital in societies where the distribution of pre-school achievement is not very dispersed. I also find that when peer effects and individuals’ pre-school achievement are close substitutes, all risk averse individuals prefer mixing.Human Capital; Efficiency; Peer Effects; Tracking, Mixing

On the optimal allocation of students when peer effect works: Tracking vs Mixing.

The belief that the behaviour and outcomes of compulsory school students are affected by their peers has been important in shaping education policy. I analyze two polar education systems -tracking and mixing- and propose several criteria for their comparison. The system that maximizes average human capital, I find, depends crucially on the level of complementarity between peer effects and individuals' ability. I also find that when mean innate ability is much higher among the rich than among the poor, the system that best maximizes average human capital is mixing. However, there is no unanimity in the overall population so as to which system to choose.Peer effects, Tracking, Mixing.

PEER GROUP EFFECTS AND OPTIMAL EDUCATION SYSTEM

The belief that peers' characteristics influence the behavior and outcomes of students in school has been important in shaping public policy. How peers affect individuals depends on the educational system prevailing. I analyze two different systems: tracking and mixing, and I propose several criteria to compare them. I find that at compulsory level, average human capital across the population is maximized under tracking, although tracking does not dominates mixing according to first order stochastic dominance. The education system that maximizes college attendance depends on the income level in the population and on the opportunity cost of college attendance.Peer Effects, Tracking, Mixing, Income Premium

Should we raise public expenditure on basic education and reduce expenditure at college?

This paper analyzes public intervention in education, taking into account the existence of two educational levels: basic education and college education. The government decides per capita expenditure at each level and the subsidy for college education. We explore the effect of transferring money from one level to the other on equity and efficiency. We find that there is always a policy reform that satisfies both the objectives of equity and efficiency, where efficiency refers to average productivity of college graduates. For developed countries, this policy consists of transferring resources from college education to basic education.Basic education, college education, public expenditure in education.

Does grade retention affect achievement? Some evidence from PISA

Grade retention practices are at the forefront of the educational debate. In this paper, we use PISA 2009 data for Spain to measure the effect of grade retention on students achievement. One important problem when analyzing this question is that school outcomes and the propensity to repeat a grade are likely to be determined simultaneously. We address this problem by estimating a Switching Regression Model. We …find that grade retention has a negative impact on educational outcomes, but we confi…rm the importance of endogenous selection, which makes observed differences between repeaters and non-repeaters appear 14.6% lower than they actually are. The effect on PISA scores of repeating is much smaller (-10% of non-repeaters average) than the counterfactual reduction that non-repeaters would suffer had they been retained as repeaters (-24% of their average). Furthermore, those who repeated a grade during primary education suffered more than those who repeated a grade of secondary school, although the effect of repeating at both times is, as expected, much larger.Grade retention, educational scores, PISA

On the identification of the effect of education on health: a comment on Fonseca et al. (2020)

In this note we revisit the paper by Fonseca et al. (Series 11: 83-103, 2020) who find that education has a positive effect on health. They use several compulsory schooling reforms as instruments for education. Our objective is to replicate this causal finding, so we start by thoroughly discussing their identification strategy. In particular, we emphasize the importance of carefully defining birth cohort groups and using country-specific time trends. Once we take these issues into account, we show that the instrument they use is too weak

Should we transfer resources from college to basic education?

This paper analyzes public intervention in education, taking into account the existence of two educational levels: basic education and college education. The government decides per capita expenditure at each level and the subsidy for college education. We explore the effects of transferring resources from one level to the other on equity and efficiency, where efficiency refers to average productivity of college graduates. Except in the special case in which the economy is at the Equity-Efficiency Frontier (EEF), there is always a policy reform that increases the productivity of college graduates without excluding the talented poor from college. For developed countries, this policy consists of transferring resources from college to basic education.Basic education, college education, public expenditure in education
