Abstract
Strong intergenerational associations in wealth have fueled a long-standing debate over why students of low-income parents tend to have on average lower incentives to be highly educated. Understanding the role of preferences, attitudes, and future expectations according to social background seems crucial in the students’ decision to invest in higher education. Perceptions about the consumption value of education may explain a substantial share of the variation in students’ ability to prosecute their study, influencing their probability of finding a job. For this purpose, we conducted a randomized control experiment with university students in Emilia-Romagna who benefit from the financial aid program offered by the regional public system. We want to explore what type of message is more effective in eliciting aid recipients’ attitudes and expectations. In particular, we compare messages stressing the importance of receiving public grants compared to the role of education in terms of career success. We can document whether or not students’ beliefs about the consumption value of tertiary education predict students’ beliefs compared to how likely public grants may help obtain the necessary grades to proceed into the labor market stage with a more significant probability of success. Differences in the perceived consumption value of education across gender and socio-economic groups can account for a large proportion of the gender and socio-economic gaps both in students’ intentions to select some jobs as well as in their perceptions about their performance. In this direction, a spatial regression evaluation can be derived based on the geographical residence of the students’ families.

Experimental Details

Interventions

Intervention(s)
The information treatment involves two messages and we want to explore what type of message is more effective in shifting aid recipients’ expectations and education performance. The first message stresses the importance of receiving and keeping public grants for students’ educational success; the second message focuses on the consumption value of tertiary education.

Secondary Outcomes

Secondary Outcomes (end points)
We will explore treatment heterogeneities by the following students’ characteristics:
Income and Socio-Economic Background, Gender, Ex-ante performance, Migration Status, Major type
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
Hypothesis: If the respondent receives information on the fact that the probability of their educational success is higher when they receive and keep the public grant, they will be more likely to shift their expectations and performance than the control group. We also expect students receiving information on the fact that the probability of their job success is higher when they complete tertiary education, to have better future expectations and increase their educational performance.
Experimental Design Details
We invited the full population of university students in the Emilia-Romagna Region who benefit from the financial aid to participate in the experiment, i.e. a total of XXXX students in the 2021/2022 academic year. The message will be randomly assigned at the student level following a between-subject design. Students in the control group will not receive any message.
Randomization Method
Randomization performed by Qualtrics, the survey software we use to conduct the survey.
Randomization Unit
Randomization is performed at the individual level stratifying the sample by gender, residence and migration status.
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
All people that have access to educational grants in the four Universities in the region of Emilia Romagna, e.g. 22000 students.
Sample size: planned number of observations
20% of the full population: 0.20*22.000=4400
Sample size (or number of clusters) by treatment arms
1466 students in the control, 1466 students in the info1 treatment, 1466 students in the info2 treatment
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Given sample size and sample variance, we can calculate the smallest real effect size which we would be able to detect at 80% power. This value is called the minimal detectable effect with 80% power, or 0.8 MDE.
