Estimation of the impact of the statutory labor hours cut on labor earnings in Korea

Abstract

In this paper we estimate the impact of the statutory labor hours cut in Korea on monthly labor earnings by the regression discontinuity design (RDD) method. The implementation of the statutory labor hours cut policy was sequentially extended based on the number of corporation’s employees. The estimation results show that the statutory labor hours cut did not make the workers receiving the treatment better off on average throughout the entire period of 2004-2008 in the sense that it raised monthly labor earnings. However, the policy intervention is found to substantially improve the welfare of workers in the treatment group in 2007 and 2008. © 2017, Korean Econometric Society. All rights reserved.
