Educational Reform, Ability, and Family Background
评估了瑞典1950年代的一项重大教育改革（包括延长义务教育、统一课程、取消12岁分科）对教育程度和收入的影响，发现该改革提高了父亲仅受过义务教育的孩子的教育程度和收入，但降低了父母受过教育的孩子的收入。
In this paper we evaluate the impact of a major school reform, that took place in the 1950s in Sweden, on educational attainment and earnings. The reform, which has many common elements with reforms in other European countries including the UK, consisted of increasing compulsor schooling, imposing a national curriculum and abolishing selectionby ability into Academic and non-academic streams at the age of 12 (comprehensive school reform). Our data combines survey data with administrative sources. We find that the reform increased both the educational attainment and the earnings of children whose fathers had just complusory education. However the earnings of those with educated parents declined - possibly because of a dilution of quality at the top end of the education levels. The overall effect of the reform was however positive.
