공공부문 비정규직의 이행과 임금페널티 분석

This study examines transitions and wage penalties between employment statuses in the public and private sectors, using the six-year data of the Labor Panel from 2005 to 2010. The probability of the transition of contingent employment to regular employment in the public sector is 7.0%. The 2/3 of the transition, however, was exceptional since it was mainly the result of some temporary government policies. 22.5% of contingent workers in the public sector moved to contingent employment in the private sector, while only 4.1% of contingent workers in the public sector moved to regular employment in the private sector. This contrasts with the fact that 10.1% of contingent workers in the private sector moved to regular employment in the same sector. The analysis of wage differences between employment statuses in both sectors, using the OLS model and the fixed effect model, shows that wage penalty on contingent workers was more than 9.9%, and 5.7% even after controlling unobserved individual qualities. Moreover, the wage penalty on contingent workers against their regular counterparts in the public sector was 10.3%, which is much higher than 5.2% in the private sector, showing that wage discrimination against contingent workers is harsher in the public sector than in the private sector.
