원가행태의 비대칭성과 산업별 특성 차이에 대한 종합적 분석

초록

This study analyses cost behaviour with regard to asymmetric behaviour and inter-industry differences for total costs, CGS, SG&A, and discretionary costs to Korean firms over the 1990-2007 period. Building upon the existing studies, it endeavours to provide a more detailed and comprehensive analysis in terms of data period, cost items, independent variables, levels of change in activity volume, and inter-industry analysis. Further, it attempts to compare and contrast existing studies on cost stickiness. Key findings of the study are as follows. Firstly, generally different industries show different cost stickiness except for total costs. Secondly, all industries of interest tend to show stickiness for most cost categories when change in sales revenue is greater than ±50%, but the tendency is not apparent in the cases of below 50%. Thirdly, for most industries, inventory intensity, non- current asset intensity, debt ratio, and consecutive decrease in sales revenue generally affect stickiness for total costs, CGS, and SG&A, but it seems that discretionary cost and its constituents are largely unaffected by these factors.
