노동유연화가 인건비 행태에 미치는 영향

This study investigates the effects of labour flexibility on the behaviour of labour costs through the change of labour adjustment costs by employment protection legislation. We divide the investigation periods into three groups according to their level of labour flexibility; 1st period(low or middle flexibility; 1984-1987), 2nd period(low flexibility; 1988-1987), and 3rd period(high flexibility; 1998-2015), and investigates the costs behaviour of personnel expenses and labour costs of each periods through Anderson et al.(2003) Basic and Extensive Models and Banker et al.(2010) ANOVA Model. Our findings show that the cost behaviour of personnel expenses and labour costs are symmetric in 1st period, but the cost behaviour of them are asymmetric in 2nd period which the level of labour flexibility is low. In the 3rd period with high flexibility of labour, personnel expenses show symmetric cost behaviour, but labour costs show anti-stickiness. For a comparative purpose, the cost behaviour of selling and administrative expenses are sticky. The results of these are similar in Banker et al.(2010) ANOVA Model. These results imply that the low(high) level of labour flexibility increases(decrease) the labour adjustment costs, consequentially lay off(retain) the unused man power when activity levels decrease. Accordingly, the hypothesis of the labour flexibility affects on the behaviour of labour costs is not rejected.
