Figure 2
University Enrollment and Share of Peers with C Feedback.
Notes: The figure represents the relation between individual enrollment at university and the proportion of peers with C feedback. Dots are data averages over small intervals. The black continuous line represents the predicted value from a regression of the enrollment dummy variable on a polynomial function of order three of the share of peers with C feedback. The dashed grey lines represent 95% standard errors. The regression coefficients used to compute the predicted values are displayed in Table A3. The predicted value is computed from individual data and not data averages.

Balancing tests for the proportion of peers with C feedback.
Notes: The figure represents the estimated coefficient from the separated regressions of each individual's observable characteristics on the share of peers with C feedback. The left panel displays OLS regressions, while the right panel presents fixed-effect regressions using major-by-high-school-by-year fixed effects and controlling by the peers mean characteristics; horizontal red lines are the standard errors.
