TY - JOUR AB - Does school spending raise achievement? I show that effects, benchmarked by schools’ daily value added, are one-tenth to one-third as large as spending growth. Using school finance reforms for identification, I show that schools did not raise quality measured by value added. Instead, schools raised quantity measured by time diaries of staff and student hours, more than spending, with most hours added after testing. Private time costs of reforms exceed public costs. Achievement effects are small due to fadeout and delayed measurement, suggesting long-run economic effects may be more informative.
