This study tests an intervention that introduces a structured curriculum for five-year olds into the universal preschool context of Norway. We conduct a field experiment with 691 five-year-olds in 71 preschools and measure treatment impacts on children’s development in mathematics, language...

This paper presents the first analysis of the life course outcomes through late midlife (around age 55) for the participants of the iconic Perry Preschool Project, an experimental high-quality preschool program for disadvantaged African-American children in the 1960s. We discuss the design of...

Many development programs that attempt to disseminate improved technologies are limited in duration, either because of external funding constraints or an assumption of impact sustainability; but there is limited evidence on whether and when terminating such programs is efficient. We provide...

The Post-9/11 GI Bill allows service members to transfer generous education benefits to a dependent. We run a large-scale experiment to test whether active choice framing impacts US Army service members' decision to transfer benefits. Individuals who received email messages framing GI Bill use...

This paper studies inference in randomized controlled trials with covariate-adaptive randomization when there are multiple treatments. More specifically, we study in this setting inference about the average effect of one or more treatments relative to other treatments or a control. As in Bugni...

This paper studies inference for the average treatment effect in randomized controlled trials where treatment status is determined according to a "matched pairs" design. By a "matched pairs" design, we mean that units are sampled i.i.d. from the population of interest, paired according to...

We analyze a labor market program that subsidizes skill-upgrading occupational training for work-ers employed in small and medium sized enterprises. The program covers a substantial share of training costs. Nonetheless, take-up has been low. In an experimental setup, we mailed 10,000 brochures...
