This study purposes to analyze how the level of diversification affects cost stickiness behavior. Specifically, we document that cost stickiness behavior is bigger in case of firm with a high level of related diversification. The purpose mentioned above are empirically tested using 1,508 firm-year data listed on Korea Stock Exchange from 2000 to 2009 and regression analysis methods were used for the analysis of the research hypotheses. The following are the results of this study : First, the increase in SG&A(selling, general and administrative costs) as sales increases is greater than the decrease in SG&A in respect to the equivalent decrease in sales. Second, cost stickiness behavior is bigger in case of firm with a high level of diversification. Also, cost stickiness behavior is bigger as the level of related diversification increase. These results imply that the level of diversification effects on the cost stickiness behavior.

The purpose of this case study is to verify the usefulness of three costing models and a minimum profit management model that can support the logistics warehouse companies in the Busan Newport Distri-park. This case study investigated traditional costing, activity-based costing (ABC), and time-driven ABC (TDABC); and suggested that an appropriate minimum profit management model is contribution margin analysis. Accordingly, in order to verify the usefulness of models, this case study surveyed the actual cost management conditions of companies, applied the three costing models to the "K" warehouse company in the Busan Newport Distri-park, and undertook a comparative study of the results. This case study produced two main findings. First, TDABC was verified as the most useful and advanced of the three costing models tested. Second, contribution margin analysis was confirmed to be the most suitable model to manage minimum profits for port warehouse companies in the Busan Newport Distri-park.

This study examined whether there is a difference in cost asymmetry between a corporate listed on KOSDAQ and a corporate listed on KOSPI, and whether there is a difference in cost asymmetry depending on the size of the listed corporate. In the previous study, cost asymmetry was examined only for listed corporate, but the difference in size between KOSDAQ-listed corporate and KOSPI-listed corporate was not examined. However, according to many studies, since the characteristics of corporate and firm risks are different between corporate listed on KOSPI and corporate listed on KOSDAQ, or even for listed corporate, such an impact may affect the decision-making of internal resource allocation. The analysis was conducted that there would be a difference in the impact. For this study, the results of analyzing the KOSPI and KOSDAQ markets from 2011 to 2019 using the cost behavior model of Anderson et al. (2003), There was a difference in cost behavior in the KOSPI and KOSDAQ markets. Overall, as in previous studies, Cost Stickiness was appeared. but in the case of the KOSPI market, Cost Stickiness was mitigated.It was found that corporate with large corporate size made the decision to dispose of idle resources more clearly when sales decreased. In addition, it was observed that the higher the foreign investor's ownership ratio, the KOSPI market, and the larger the corporate size, the more clearly the Stickiness of cost was mitigated. This study expands research on cost asymmetry and reveals that there is a difference between the KOSPI market and the KOSDAQ market, and between the size of the corporate, and has a differentiation from previous studies.
