Motivation
Aspirations and poverty• Standard poverty traps are generated by external constraints:
malnutrition (Dasgupta-Ray 1986), credit mkt imperfections (Banerjee-Newman 1991), etc.
• Internal constraints may also generate poverty traps, leading to aspiration failures (Appadurai 2004; Dalton, Ghosal, Mani 2014; Genicot-Ray 2016)Poverty low asp. low investment poverty...
Stereotypes and poverty• Above mechanism particularly relevant for groups that are
negatively stereotyped or discriminated in society.Stereotype threat: anticipate & internalize stereotype underperform (Steele-Aronson 1995)

This lecture
• How do aspirations and stereotypes play out in a context where investment has long term consequences, i.e., education?
• Study two different potentially marginalized groups: immigrants in Italy and Black South-Africans in SA
• Combine administrative & experimental data
• Consider different social interactions: w/ teachers & w/ peers
Plan of the talk1. Educational choices of immigrant children in Italy
• Aspirations & psychological factors2. Teachers’ stereotypes
• Effect of revealing own bias3. Peers’ stereotypes
• Effect of inter-group contact

Early tracking and educational choices
Carlana, La Ferrara, Pinotti Goals and gaps
Greater disadvantage in educational systems characterized by early tracking (Cobb-Clark et al. 2009)• Information gaps (Dustmann et al. 2014)• Aspiration traps (Genicot and Ray, 2014; Guyon and Huillery, 2014)
High-school choice is an early career decision w/ long term consequences on labor mkt outcomes (Giustinelli, 2011)
Research questions• Do immigrant children under-aspire when choosing high
school in an early tracking system?• Can we align their aspirations w/ their academic potential?
o Evaluate a large-scale program targeting high-achieving immigrant students in Italy
![Page 6: Aspirations, Stereotypes and Educational Choicespubdocs.worldbank.org/en/950851557242051768/DEC... · Aspirations, Stereotypes and Educational Choices Eliana La Ferrara Bocconi University,](https://reader030.fdocuments.net/reader030/viewer/2022040617/5f1f10a963bc2f33e773e9a7/html5/thumbnails/6.jpg)
The Italian schooling system
Stratification of students after 8th grade into 3 tracks
• Academic oriented (liceo) college• Technical college or white collar jobs• Vocational blue collar jobs
Carlana, La Ferrara, Pinotti Goals and gaps
Vocational track worse under several dimensions (e.g., earnings, ex post satisfaction, etc.)
![Page 7: Aspirations, Stereotypes and Educational Choicespubdocs.worldbank.org/en/950851557242051768/DEC... · Aspirations, Stereotypes and Educational Choices Eliana La Ferrara Bocconi University,](https://reader030.fdocuments.net/reader030/viewer/2022040617/5f1f10a963bc2f33e773e9a7/html5/thumbnails/7.jpg)
Fact 1: Educational segregation
• Immigrant students disproportionately choose vocational track compared to Italians
Carlana, La Ferrara, Pinotti Goals and gaps
• Need to control for ability use standardized test score in math & italian (Invalsi) in 6th grade as proxy for academic potential
![Page 8: Aspirations, Stereotypes and Educational Choicespubdocs.worldbank.org/en/950851557242051768/DEC... · Aspirations, Stereotypes and Educational Choices Eliana La Ferrara Bocconi University,](https://reader030.fdocuments.net/reader030/viewer/2022040617/5f1f10a963bc2f33e773e9a7/html5/thumbnails/8.jpg)

The intervention
“Equality of Opportunity for Immigrant students” (EOP)• Program in collaboration w/ Ministry of Education (MIUR)• Target: high-performing students from low-income countries in
lower secondary school• Goal: align their HS choice w/ their academic potential
Schools• All schools w/ >20 immigrant students in 5 provinces of
Northern Italy 145 schools: randomize 70 treatment, 75 control
Carlana, La Ferrara, Pinotti Goals and gaps
Individuals• In each school, the 10 immigrant students w/ highest Invalsi
test score in 6th grade (only countries w/ GDP pc < Italy) Takeup rate: 79%

The intervention
Students followed during grades 7 and 8.Two types of activities:
Carlana, La Ferrara, Pinotti Goals and gaps
1. Career choice consultancy
• Information about Italian schooling systemo type of high-schools, job opportunities, booklet translated in
language of home country
• Psychological support based on Social Cognitive Career Theory
• 14 meetings during grades 7-8: 5 group meetings, 5 individual, 3 w/ parents, 1 w/ teachers
![Page 13: Aspirations, Stereotypes and Educational Choicespubdocs.worldbank.org/en/950851557242051768/DEC... · Aspirations, Stereotypes and Educational Choices Eliana La Ferrara Bocconi University,](https://reader030.fdocuments.net/reader030/viewer/2022040617/5f1f10a963bc2f33e773e9a7/html5/thumbnails/13.jpg)
Examples of psychological support activities
Carlana, La Ferrara, Pinotti Goals and gaps
• Peer education, e.g., video on barriers and self-efficacy of high-school students
• “Thinking about your past life, indicate 5 study experiences and 5 other experiences that you have completed successfully… which personal resources helped you doing well in that thing”
• “Please find below the professions you selected and indicate which resources are needed (knowledge, skills, personality traits, motivations, ... ) then divide them into “I have it” and “I need to develop it”
• “Please list the results you would like to achieve with your job”

The intervention
Carlana, La Ferrara, Pinotti Goals and gaps
2. Cognitive Academic Language Proficiency (CALP)
• Tutor on Italian language to facilitate studying and learning allsubjects• # meetings higher for students w/ lower Invalsi scores in
grade 6 (2 thresholds, though little variation)
• The 2 components (Career consultancy & CALP) offered as joint package, not a 2x2 designo “ethics”

2. Non-cognitive skills
Questionnaire on a broad range of psychological variables, including info on:
• Goals: e.g., which educational level do you want to achieve?
• Self-efficacy: e.g., thinking about your ability, do you think you could get a university degree?
• Perceived barriers: e.g., do you think the following barriers could be an obstacle to achieving your educational goals: economic barriers, racial prejudice, ideas of the family…?
Carlana, La Ferrara, Pinotti Goals and gaps
Aggregate into 2 indexes through principal component analysis:
• Academic motivation
• Perceived barriers

Probability of recommending high track
Carlana, La Ferrara, Pinotti Goals and gaps
Effect only for boys, who had shown improvements in academic performance not driven by experimenter demand effects
![Page 26: Aspirations, Stereotypes and Educational Choicespubdocs.worldbank.org/en/950851557242051768/DEC... · Aspirations, Stereotypes and Educational Choices Eliana La Ferrara Bocconi University,](https://reader030.fdocuments.net/reader030/viewer/2022040617/5f1f10a963bc2f33e773e9a7/html5/thumbnails/26.jpg)
Additional results
Variance decomposition
• Most of the effect explained by motivation & teachers’ recommendation
Carlana, La Ferrara, Pinotti Goals and gaps
Medium term effects
• 2 years later, treated students are no more likely to fail subjects, despite attending more demanding high schools
Spillovers
• Male classmates of treated students have lower retention rates; impact stronger on immigrants
• Improvement in “behavior” of immigrant males• No impact on high school choice for boys, but (+) impact on
female classmates (who were closer to “marginal”)• No impact on teachers’ recommendations
![Page 27: Aspirations, Stereotypes and Educational Choicespubdocs.worldbank.org/en/950851557242051768/DEC... · Aspirations, Stereotypes and Educational Choices Eliana La Ferrara Bocconi University,](https://reader030.fdocuments.net/reader030/viewer/2022040617/5f1f10a963bc2f33e773e9a7/html5/thumbnails/27.jpg)
Summing up
• EOP reduced educational segregation: +12% enrollment in demanding high schools for immigrant boys, closing gap w/ comparable Italians
• Mechanisms: motivation & teachers’ support
Policy implications• Role of ‘soft skills’ suggests potential information &
“aspirations” interventions, ideally scalable & cheaper to implement
Carlana, La Ferrara, Pinotti Goals and gaps
• Role of teachers’ recommentations suggests working on teachers’ attitudes towards immigrant students, in particular stereotypes next paper

2. Revealing stereotypes: Evidence from immigrants in schools(with A. Alesina, M. Carlana and P. Pinotti)
Stereotypes are over-generalized representations of differences between groups (Bordalo et al., 2017)• Allow for easier and efficient processing of information• May cause discrimination, i.e. biased judgment against
particular groups
If discrimination occurs in a critical period for educational choices, this may discourage investment by disadvantaged groups• Important to study negative stereotypes in school• Link b/w stereotypes and aspirations
Alesina, Carlana, La Ferrara, Pinotti Revealing stereotypes

Research questions
Are teachers biased against immigrants?
• Analyze the impact of teachers’ stereotypes on bias in grading(i.e., the difference b/w teacher-assigned grades & blindly graded test scores)
How do we change teachers’ bias?
• Evaluate a simple & scalable intervention: reveal own stereotypes to teachers
• Test if this affects their grading policy• Indirect evidence about people’s awareness of their own bias

Implicit Association Test (IAT)
• Experimental method from social psychology (Greenwald and Banaji, 1995)
• Pair two concepts in rapid categorization task
• Speed in associating: mental process perceives a given pair as less common
Alesina, Carlana, La Ferrara, Pinotti Revealing stereotypes
Advantages of IAT• Reveal cognitive processes of which individuals may not be
aware (e.g., perception, stereotyping)• Or may be uncomfortable disclosing (e.g., prejudice)

• Existing literature takes grade gap as evidence of discrimination (Gilliam et al., 2016; Botelho et al., 2015; Burgess and Greaves, 2013; Hanna and Linden, 2012; Van Ewijk, 2011; 2018; Lavy, 2008)
• However, it could reflect unobservables:o e.g., multiple choices standardized test scores may be easier
for immigrants than teacher-assigned examso e.g., teachers may observe characteristics (effort, discipline)
that differ b/w natives and immigrants
To isolate bias, we test if the gap in grading is correlated w/ teachers’ IAT

Why different results for Math & Literature teachers?
• Standardized test scores in math may be better at measuring skills valued by teachers when grading than those in reading (Bettinger, 2012)
Alesina, Carlana, La Ferrara, Pinotti Revealing stereotypes
• Literature grades may reflect different standards for teachers w/ different expectations on immigrants' language skills - and these expectations may be correlated w/ IAT
o We find that Literature teachers w/ higher IAT give better grades to 1st vs 2nd generation immigrants, ceteris paribus

Approach 1: exploit information on explicit bias
• WVS question on right to job: teachers who openly state that natives have more rights than immigrants should be less “surprised” by email feedback
• We expect smaller (or no) adjustment in grades

Summary & policy implications
• Revealing own stereotypes to teachers reduces bias in grading
o Suggests that teachers were not aware of (or had not fully internalized) their own stereotypes

Stereotypes not only by teachers but also by peers
• Can stereotypes be changed through interaction w/ members of a different group?
• How does this affect academic performance?
Answer these questions exploiting random exposure to roommate in some dorms at University of Cape Town• South Africa is a particularly interesting context, as apartheid led
to stereotyping & marginalization of blacks

Discussion
Corno, La Ferrara, Burns Interaction, stereotypes & performance
Why does black students’ performance improve?• Not because (white) roommate is more skilled: we control for
admission score
Possible channels• Role modeling: learning how to navigate the system• Network effects: different set of peers• Fewer opportunities for joint “distractions”• Anxiety reduction
• Impact on academic outcomes persists at the end of year 2 (not for GPA but for # exams passed and eligibility to continue)
