Score contribution per author:
α: calibrated so average coauthorship-adjusted count equals average raw count
While the previous literature finds robust evidence that children who enter school at a more advanced age have better test scores than their younger classmates, only little is known about the persistence of this effect into adulthood. This study is the first to analyze whether the school starting age even affects test scores long after school graduation. The scores were conducted as part of a representative survey of adults, measuring math and language competencies. Exploiting state and year variation in school entry regulations, the results show that a higher school starting age significantly increases competencies in receptive vocabulary.
