Can a smaller-class at school lead to a better educational outcome and more equality in achievement? We estimate the causal effects of class-size on achievement tests by using discontinuous changes in class-size under the Japanese public compulsory education system. We employ a value-added model...

Using data for the 1990's, this paper examines the role of sheepskin effects in the returns to education for Japan. Our estimations indicate that sheepskin effects explain about 50% of the total returns to schooling. We further find that sheepskin effects are only important for workers in small...
