We also show that Colombia's staggered rollout of a new signal of skill—a college exit exam—reduced the earnings return to reputation and increased the return to individual admission scores. These results are consistent with the hypothesis that a college's reputation provides information about the ability of its student body and about its value added, broadly understood
