We examine earnings records for 90,000 classroom teachers employed by Florida public schools between the 2001-02 and 2006-07 school years, roughly 20,000 of whom left teaching during that time. Among grade 4-8 teachers leaving for other industries, a 1 standard deviation increase in estimated...

Online education options have proliferated in recent years, with significant growth occurring at state-sponsored virtual schools. However, there is no prior credible evidence on the quality of virtual courses compared to in-person courses in U.S. secondary education. We compare the performance...

We examine whether the sorting of differently achieving students into differently sized classes results in a regressive or compensatory pattern of class sizes for a sample of national school systems. Sorting effects are identified by subtracting the causal effect of class size on performance...

We employ a combination of school fixed effects and IV estimation to estimate the effect of class size on student performance in 18 countries. Using the random part of the class-size variation between two adjacent grades within individual schools allows us to identify causal class-size effects....

We estimate the effect of class size on student performance in 18 countries, combining school fixed effects and instrumental variables to identify random class-size variation between two adjacent grades within individual schools. Conventional estimates of class-size effects are shown to be...

Nineteenth-Century Catholic doctrine strongly opposed state schooling. We show that countries with larger shares of Catholics in 1900 (but without a Catholic state religion) tend to have larger shares of privately operated schools even today. We use this historical pattern as a natural...

We use statewide administrative data from Florida to estimate the impact of attending public schools with different grade configurations on student achievement through grade 10. To identify the causal effect of structural school transitions, we use student fixed effects and instrument for middle...
