Subjective beliefs and inclusion policies: evidence from college admissions

What is this research about and why did you do it?

Research shows that university enrolment from disadvantaged groups can lag despite financial aid, suggesting that preferential admission policies could be a better way to increase the enrolment of disadvantaged students (Chetty et al, 2020). In fact, admission officers and governments around the world are adopting targeted admission policies to reduce inequalities in higher education. But in this paper, we show that information frictions can curb the effectiveness of these policies in bringing disadvantaged talent to college. We studied this topic to understand how to best design policies that can close the gap in university participation between rich and poor students. 


How did you answer this question?

We analysed data from a Randomised Controlled Trial in Chile, where 128 high-schools were randomly assigned to be part of a preferential admission programme or not.  This allowed us to establish the impacts of this policy on university admissions and enrolments. To understand the role of information frictions, we surveyed students  and found that their beliefs about the likelihood of gaining admission are incorrect. We then used economic modelling to understand how these information frictions interacted with policy effectiveness. The model quantified how the biases in subjective beliefs affected investments in admission credentials, and ultimately who gets admitted to college. 


What did you find?

We found that preferential admissions can increase the admission and enrolment rates of disadvantaged students. But information frictions can curb their effectiveness in bringing disadvantaged talent to college. This is because they can lead overconfident but underprepared students to enter college. Providing high-school students with correct information about their university admission chances when introducing preferential admissions can avoid these distortions and lead to a pool of college entrants that is better-prepared.


This Figure shows results from the model simulations. It plots the effect that biases in subjective beliefs about admission chances have on admissions, as a function of students ability, measured by the SIMCE test score. SIMCE is a standardised test taken at baseline (grade 10). The effect of belief biases is obtained by taking the difference between admissions simulated in the baseline scenario in which students have biases in beliefs and in a counterfactual scenario in which students have no biases in their beliefs. The graph shows that, both with and without preferential admissions, belief biases lead low- and middle-ability students to enrol at a higher rate than the rate at which they would enrol if they had correct beliefs, and vice versa for high-ability students. The over-enrollment of low- and middle-ability students is more pronounced under preferential admissions, suggesting that preferential admission can exacerbate the distortions in the composition of college entrants that arise when high-school students are misinformed about their admission chances.

What implications does this have for the research on wealth concentration or economic inequality?

University education can promote intergenerational mobility, one of the most powerful tools to reduce wealth concentration. But university enrolment is severely unequal across socio-economic lines globally. Our study shows that preferential admission policies can play a central role in reducing inequalities, but their design can be improved to better achieve their intended objectives. Eliminating information frictions by, for example, providing individualised information on admission chances into different programs, in contexts where preferential admissions are in place can improve the match between disadvantaged talent and university.


What are the next steps in your agenda?

I want to understand the long-term effects of preferential admissions on the disadvantaged. I will keep collecting data on the students who participated in this Randomised Controlled Trial as they progress through university and to the labour market.
