Key points

  • The Earned Income Tax Credit (EITC) caused significant, nonlinear increases in family income.
  • A $1,000 increase in family income led to a 6% standard deviation rise in combined math and reading test scores.
  • Gains in test scores were more pronounced for children from disadvantaged backgrounds.
  • Results were robust across various alternative specifications.

Abstract

Using an instrumental variables strategy, we estimate the causal effect of income on children's math and reading achievement. Our identification derives from the large, nonlinear changes in the Earned Income Tax Credit. The largest of these changes increased family income by as much as 20 percent, or approximately $2,100, between 1993 and 1997. Our baseline estimates imply that a $1,000 increase in income raises combined math and reading test scores by 6 percent of a standard deviation in the short run. Test gains are larger for children from disadvantaged families and robust to a variety of alternative specifications. (JEL H24, H31, I21, I38, J13)
