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...

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....

To study whether current spending levels and public knowledge of them contribute to transatlantic differences in policy preferences, we implement parallel survey experiments in Germany and the United States. In both countries, support for increased education spending and teacher salaries falls...

What do citizens of the United States and Germany think about their schools and school policies? This paper offers the first broad comparison of public thinking on education in the two countries. We carried out opinion surveys of representative samples of the German and American adult...
