제조원가와 기간비용 원가행태 비교 연구

This study investigates whether cost stickiness occurs in manufacturing parts and selling, general, and administrative parts using a sample of Korean firms during the period from 1982 to 2003. We compare the behaviour of cost of goods sold, labour costs and depreciation costs between manufacturing activities and selling, general, and administrative activities associated with the change of sales activity through ABJ Basic and Extensive Models and Banker ANOVA Model. We review cost stickiness theory, the results and the meaning of those studies. Our findings show that cost stickiness occurs in labour cost and depreciation cost for selling, general, and administrative activities, but not in labour cost and depreciation cost for manufacturing activities. These result show that management whose sales revenue falls holds the surplus resources to avoid the adjustment costs in the future when sales are restored. Although the labour and depreciation costs for manufacturing activities are not statistically significant, the sign and the magnitude of the coefficient suggest that the Korean firms probably dispose the surplus resources for manufacturing activities more rapidly than that of selling, general, and administrative activities when sales falls, considering the non-stickiness of these costs for manufacturing activities.
