도시의 집적도가 임금노동자들의 초과노동시간과 임금보상에 미치는 영향

This paper examines the impact of agglomeration economics on wage workers’ overtime and the wage compensation for overtime using KLIPS (Korea Labor and Income Panel Study) data. The labor market is differentiated by occupation, but there is an imperfect substitution relationship among occupations due to different tasks in different industries. The effect of agglomeration on overtime was determined by distinguishing the labor density at the region-occupation level, the labor density at the region-occupation-industry level, industrial diversity index for specific occupations, specialization at the region- occupation level, and specialization at the region-occupation-industry level. In particular, using the multi-layered classification method of the Korean Standard Classification of Occupations Code, the analysis was divided into professional groups, white-collar groups (such as service and sales), blue-collar groups (such as technicians and assembly workers), and simple labor groups, and the results were generally the same for all four occupational groups and pooled group. Overtime increased with increasing worker density, and decreased with increasing diversity and specialization. In general, overtime has a positive effect on wages in the next period. However, overtime caused by agglomeration has either negative effect or no effect on wages, indicating that agglomeration leads to under-compensation for overtime labor.
