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 study with a sample of 1,070 primary school children, aged seven to eleven years,how altruism in a donation experiment is related to children’s risk attitudes and intertemporalchoices. Examining such a relationship is motivated by theories of reciprocalaltruism that provide a cornerstone to...

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...

We estimate the relationship between computers and students’ educational achievement in the international student-level PISA database. Bivariate analyses show a positive correlation between achievement and computer availability both at home and at school. However, once we control extensively...
