Concentration and Wage Earnings in an Open Economy: A Case Study of Korea

The object of this paper is to increase our understanding of the effect of output market power (the degree of concentration in an industry) on wage earnings in Korea. We conduct a series of econometric investigations based on the traditional human capital theory and find that workers in a more concentrated industry are paid higher. This wage premium is not explained in terms of the differences in the quality of labor and/or compensating factors. It suggests to us that the conventional estimates of the misallocation of resources due to the output market power are underestimated since this source of higher unit costs is disregarded. [820]
