A Question of Honor? The Labor Market Advantage of Academic Signaling
Mael Astruc–Le Souder, Olivier B. Bargain, Gedeao Locks

As tertiary education expands, employers increasingly rely on academic distinctions to screen among similarly qualified graduates. We study the labor-market effects of honors using administrative and survey data on Sorbonne master’s graduates. We exploit France’s fixed GPA thresholds for honors assignment to implement a fuzzy regression discontinuity design. Returns are concentrated at the intermediate distinction (“High Honors”), indicating that credentials are most informative when they separate above- from below-average students. We find that High Honors accelerate school-to-work transitions, increasing the monthly job-finding rate by about 40%. Honors also generate an initial wage premium, which fades within two years, and lead to persistent improvements in job quality, including greater access to master’s-level positions and faster transitions to permanent contracts. These results highlight the role of academic distinctions as short-run signals that shape early career allocation rather than long-term earnings.
