توسعه اقتصادی و تاثیر آن بر ساختار گروه بندی شغلی در کره 1971-1990

By utilizing occupational wage data in Korea, this paper attempted to find major determinants of occupational wage performance of occupational groups with a combination of cluster and discriminant analysis. This research yielded three major determinants (annual investment, credit availability, and uncovered interest parity) which were also major determinants in a previously undertaken industrial wage analysis. With these major factors, interpretations gleaned from this research confirm research findings from previous research in economics.

Utilizing wage data allows researchers in different disciplines, including economics, management, and public policy, opportunities for evaluation, assessment, and diagnosis of economic impacts and policy legacy. This paper, in particular, focuses on the Korean wage data set, the Occupational Wage Survey(OWS), in evaluating the economic impact of development of occupational grouping structures. Previous research 1, 2 and 3 utilizing industrial wage section of the OWS yielded two or three important determinants of wage performance in Korea from 1971 to 1991. Those were investment and uncovered interest parity 2 and 3; an earlier paper [1] found investment, real interest rate and credit availability as the major sources that have driven the wage performance in Korea. Following this line of study, but with the unused half of the OWS, the occupational wage section, this paper investigates the major determinants of occupational wage performance in Korea in the period from 1971 to 1990. While finding the determinants, this paper looks at the occupational grouping structure that has been formed during the recent two decades of rapid industrialization. Interesting questions arise from the two basic research focuses. The first is whether the determinants would be identical or different from past research using the industrial section of the OWS. The second question is whether this paper can find the evidence of occupational rent in the Korean data set. The third is to determine wage differentials between occupational categories with different educational backgrounds. Findings from this research will supplement the existing research tradition in labor economics. Furthermore, with the second and third questions, this research leaves for the future the task of comparing the results with other countries.

This research yielded three major determinants of occupational wage performance in Korea from 1971 to 1990. An interesting finding was that the three roots were found as the major determinants of industrial wage section of the Korean economy in the 1971 to 1991 period 1, 2 and 3. Therefore, it would be interesting to see whether identical common determinants exist in other countries for both occupational and industrial wage data, if data availability permits. If this happens, the validity of this research would be enhanced greatly. In the case where there is a spectrum of countries regarding the commonality of determinants, it would also be a starting point for an international comparison.
