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....

Between 1930 and 1970, average school size in the United States increased from 87 to 440 and average district size increased from 170 to 2,300 students, as over 120,000 schools and 100,000 districts were eliminated via consolidation. We exploit variation in the timing of consolidation across...

International comparative studies of student performance have initiated political discussions in countries all over the world on how to improve the educational achievement of students. The empirical evidence suggests that central exams help to achieve higher student performance. Central exams...

We estimate the relative roles of factor inputs and productivity in explaining the level of economic development, which is measured as output per worker. For a large sample of countries, we show that alternative identifying productivity assumptions and alternative measures of human capital have...

New evidence confirms the conclusion of former surveys that the link between school resources and student performance is generally missing in educational production. While the conventional within-country cross-section evidence remains controversial, recent contributions which control for...

Based on Baumol's cost-disease model, we develop two alternative measures of the change in the productivity of schooling. Both productivity measures are based on changes in the relative price of schooling. We find that in most OECD countries the price of schooling has increased faster in 1970-94...
