A straightforward way to prevent students from leaving education without a higher secondary diploma is increasing the compulsory education age. The idea is that, by staying longer in school, more students eventually obtain a higher secondary diploma. This paper examines the impact of a one-year increase in compulsory school-age on dropping out of secondary education by a difference-in-differences analysis. For this, we exploit a recent compulsory education policy reform in the Netherlands. After controlling for confounding factors and observable covariates, we find that the one year increase in compulsory school-age reduces dropout by 2.5 percentage points. The effect, however, is entirely situated in the group non-liable to the policy reform. We observe that native Dutch vocational students, mostly without retention in grade, but also without a higher secondary diploma at hand, more often left school in the immediate period before the policy reform. Given the economic revival at that time, this may reflect anticipation of labor market opportunities. 相似文献

Recent studies conclude that teachers are important for student learning but it remains uncertain what actually determines effective teaching. This study directly peers into the black box of educational production by investigating the relationship between lecture style teaching and student achievement. Based on matched student-teacher data for the US, the estimation strategy exploits between-subject variation to control for unobserved student traits. Results indicate that traditional lecture style teaching is associated with significantly higher student achievement. No support for detrimental effects of lecture style teaching can be found even when evaluating possible selection biases due to unobservable teacher characteristics. 相似文献

This paper investigates empirically whether immigrant students in Switzerland perform poorly compared to their native counterparts and provides some explanations. Using a national sample of the 2000 PISA (Programme for International Student Assessment) database, we first analyze the impact of immigrant status on pupils’ achievement. We find a negative and significant impact of immigrant status on test scores in reading, mathematics and science literacy, even after controlling for a set of characteristics. We then decompose the observed reading score gap between Swiss and immigrant students to identify whether gaps in endowments explain test score differences along the distribution. Lower endowments explain most of the achievement gap in reading between Swiss and second-generation immigrants. However, lower returns explain around one quarter of the achievement gap between Swiss and first-generation immigrants for the weakest pupils. 相似文献

Although age is not supposed to be a criterion for the award of the Nobel Prize, it is commonly believed that it does play a role. Indeed, econometric evidence in this paper also suggests such a role. However, the paper finds that, if there is a preference for older Nobel candidates, this is introduced during the nomination process. The paper actually finds that the Nobel Committee does not favor older nominees and that, if anything, it seems to partially offset the age premium introduced by the nominators. 相似文献
