Ethnic Discrimination in High School Grading: Evidence from a Field Experiment
We rigorously test for ethnic discrimination in high school grading in Sweden. A random sample of the national tests in the Swedish language is graded both non-blind by the student’s own teacher and blind without any identifying information. The increase in the test score due to non-blind grading is significantly higher for students with Swedish background compared to students with foreign background. This discrimination effect is sizeable, and explains the entire difference in test scores between students with Swedish and foreign background.Discrimination; Field experiments; Education
Are boys discriminated in Swedish high schools?
Girls typically have higher grades than boys in school and recent research suggests that part of this gender difference may be due to discrimination of boys. We rigorously test this in a field experiment where a random sample of the same tests in the Swedish language is subject to blind and non-blind grading. The non-blind test score is on average 15 % lower for boys than for girls. Blind grading lowers the average grades with 13 %, indicating that personal ties and/or grade inflation are important in non-blind grading. But we find no evidence of discrimination against boys. The point estimate of the discrimination effect is close to zero with a 95 % confidence interval of ±4.5 % of the average non-blind grade.Discrimination; Field experiments; Grading; Education; Gender
Do merging local governments free ride on their counterparts when facing boundary reform?
The Western world exhibited a significant trend towards larger local governments in the twentieth century, which was driven to a large extent by boundary reforms. Boundary reforms can provide economic benefits, but may also give rise to costs driven by opportunistic political behavior. This study uses a Swedish compulsory reform to test for such behavior. The reform gives a local government the incentive to accumulate debt before a merger takes place, since the taxpayers in the new locality will share the cost. The strength of the incentive to free ride is determined by the population size of the initial locality relative to that of the new locality. I find an economically large and statistically significant free riding effect.Amalgamations Annexations Boundary reforms Common pool Difference-in-difference Fiscal policy Free riding Local governments
Automated Essay Scoring for Swedish
We present the first system developed for automated grading of high school essays written in Swedish. The system uses standard text quality indicators and is able to compare vocabulary and grammar to large reference corpora of blog posts and newspaper articles. The system is evaluated on a corpus of 1 702 essays, each graded independently by the student’s own teacher and also in a blind re-grading process by another teacher. We show that our system’s performance is fair, given the low agreementbetween the two human graders, and furthermore show how it could improve efficiency in a practical setting where one seeks to identify incorrectly graded essays
