Essays on labor market policies in Korea
This dissertation examines the impact of employment protection regulations using job duration data in Korea. In 2007, the Korean government introduced a labor market reform that required employers to convert a worker's contract from a temporary to permanent one in order to continue to employ a worker for more than two years. I analyzes the effects of the reform from the perspectives of employers and employees. ... In the third chapter, I verify if the upsurge of alternative employment arrangements is found after the 2007 Korean labor market reform in the Economically Active Population Survey (EAPS) as well as Korean Labor & Income Panel Study (KLIPS). For this, I compare the two labor market surveys, the EAPS and KLIPS, from the perspective of reported employment arrangements using the same survey questions on the employment types of wage and salary workers. However, we are confronted with a puzzle because the results using the two data sets show different patterns for the shares of temporary worker groups. The continued growth in the proportion of alternative employment arrangements after 2007 was not found in the results using EAPS data. To answer as to what factors cause the different results in the two data sets, I investigate if there are differences in demographic characteristics between the EAPS and KLIPS data sets. However, I cannot find any significant difference that is large enough to explain the different pattern of the share of alternative employment arrangements between the EAPS and KLIPS. Therefore, we conclude the difference in demographic characteristics is not a main factor causing different results in the EAPS and KLIPS.
