This paper estimates the return to education using two alternative instrumental variable estimators: one exploits variation in schooling associated with early smoking behaviour, the other uses the raising of the minimum school leaving age. Each instrument estimates a 'local average treatment...

Social experiments are powerful sources of information about the effectiveness of interventions. In practice, initial randomization plans are almost always compromised. Multiple hypotheses are frequently tested. "Significant" effects are often reported with p-values that do not account for...

We use data from the Texas Schools Microdata Panel (TSMP) to examine the extent to which dropouts use the GED as a route to post-secondary education. The paper develops a model pointing out the potential biases in estimating the effects of taking the "GED path" to postsecondary education....

This paper estimates the marginal returns to college for individuals induced to enroll in college by different marginal policy changes. The recent instrumental variables literature seeks to estimate this parameter, but in general it does so only under strong assumptions that are tested and found...

We discuss fixed and random effects models in the context of educational research and set out the assumptions behind the two approaches. To illustrate the issues, we analyse the determinants of pupil achievement in primary school, using data from the Avon Longitudinal Study of Parents and...

We study the origins of what has become one of the most radical and encompassing programmes of school reform seen in the recent past amongst advanced countries – the introduction of academy schools to English secondary education. Academies are state schools that are allowed to run in an...

Estimates using admissions lotteries suggest that urban charter schools boost student achievement, while charter schools in other settings do not. Using the largest available sample of lotteried applicants to charter schools, we explore student-level and school-level explanations for this...

We conduct a study under 2,400 third grade students at three large secondary comprehensive schools to evaluate a gifted and talented (GT) program with selective program admission based on past achievement. We construct three complementary estimates of the program's impact on student achievement....
