This paper provides new estimates of the medium and long-term impacts of Head Start on the health and behavioral problems of its participants. We identify these impacts using discontinuities in the probability of participation induced by program eligibility rules. Our strategy allows us to...

Delivering early childhood programs at scale is a major policy challenge. One way to do so is by using existing public infrastructure. This paper experimentally assesses the short-term impacts of a new government home visiting program integrated into health care services. The program changed the...
