The Head Start program, launched in 1965 and targeted to children from disadvantaged backgrounds, remains the largest early childhood care and education (ECE) program in the United States and the only one deployed at the federal level. As such, the Head Start literature spans several decades and...

Genetics confer 2-3-fold higher obesity risk through inherited mechanisms affecting appetite and metabolism, with pathways particularly modifiable during the first 1,000 days of life. We leverage the end of UK sugar rationing in September 1953, a sharp discontinuity in early-life sugar exposure...

Researchers typically collect experimental data sequentially, allowing early outcome observations and adaptive treatment assignment to reduce exposure to inferior treatments. This article reviews multiarmed-bandit adaptive experimental designs that balance exploration and exploitation. Because...
