This paper presents the results from a randomized controlled trial of Chapter One, an early elementary reading tutoring program that embeds part-time tutors into the classroom to provide short bursts of 1:1 instruction. Eligible kindergarten students were randomly assigned to receive...

What drives governments with similar revenues to publicly provide very different amounts of goods for which private substitutes are available? Key examples are education and health care. This paper compares spending by Brazilian municipalities on pre-primary education---a good that is also...

We discuss the evidence on the effectiveness of preschool programs using results from three well-known intervention studies: the Chicago Child-Parent Centers, High/Scope Perry Preschool Program, and the Carolina Abecedarian Project. Results from cost-benefit analyses of other programs for...

Two radically different descriptions of immigrant earnings trajectories in the U.S. have emerged. One asserts that immigrant men following the 1965 Immigration and Nationality Act have low initial earnings and high earnings growth. Another asserts that post-1965 immigrants have low initial...

Using historical, longitudinal data on individuals, we track the earnings of immigrant and U.S.-born women. Following individuals, instead of synthetic cohorts, avoids biases in earnings-growth estimates caused by compositional changes in the cohorts that are followed. The historical data...
