Corona-virus(COVID-19), which has affected the world economy and Korea economy widely since 2020 could have an effect on management future perspectives. Thus this paper investigate whether the effect of COVID-19 pandemic on cost stickiness is contingent on operating uncertainty. By using the sample listed in KOSPI and KOSDAQ from 2018 to 2020. I find that COVID-19 increase cost stickiness when sales growth volatility is low. This paper contribute to the literature by providing the empirical evidence which contains that the effect of COVID-19 on cost stickiness varies with operating uncertainty.

Purposes of this paper are to investigate whether managers' compensation is sticky as accounting performance(ROA) vary or not and explore further what factors influence the managers' compensation stickiness. To empirically study the stickiness of managers' compensation, we used the financial data from manufacturing firms lised in the Korea Stock Exchange(1,000 firm-year data for 4 years). The results are as follows : First, managers' compensation is sticky with respect to change in accounting performance. That is, the increase in managers' compensation as accounting performance increases is greater than the decrease in managers' compensation in respect to equivalent decrease in accounting performance. Second, the degree of managers' compensation stickiness increases when managers have influence and contribution to firm value. Specifically, the degree of stickiness is positively associated with investment opportunity set, intangible assets' value, uncertainty of firms' operating environment, complexity of organizational hierarchy. But firms' size reversely impacts on the degree of managers' compensation stickiness.

This study examines the impact of corporate social responsibility activities (CSR) on cost stickiness. The asymmetrical cost behavior in which the cost reduction rate of a company is lower than the cost increase rate of an increase in sales is called cost stickiness. In this study, we separated the companies with CSR and those without CSR, and then compared their cost behaviors. This study reports that the cost stickiness of the companies performing the CSR is stronger than the companies that did not. This means that the company needs ongoing investments to create value through the CSR, so it is difficult to reduce committed resources involved immediately when sales declines. We expect that the result of this study provides meaningful insight to participants in the capital market by presenting empirical evidence that the firms' CSR can affect the managers' costs decisions.

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.

This study investigated the effect of corporate international diversification on cost stickiness. A cost behavior that indicates a lower rate of cost reduction when the volume of sales decreases than the rate of cost increase when the volume of sales is increased is called cost stickiness. This cost behavior is caused by decisions made by considering the adjusting costs of the manager, and for corporate international diversification, the decision making on the adjustment cost of the manager has been reduced by the offsetting accruals hypothesis. From the empirical results, we observed that the cost stickiness of international diversified companies decreases. It is expected to contribute to the capital market and academia by identifying whether corporate international diversification can have a significant impact on management decision making related to costs.

This study analyzes the effects of the obsolescence assets on the asymmetry of costs. Cost asymmetry refers to a lower percentage of costs when sales fall than increases in costs when sales increase. the obsolescence asset induces various decisions, including high maintenance costs and management improvements and replacement of facilities. This study is to analyze the cost behavior according to those decisions. The analysis showed that the higher the obsolescence of assets rate, we found cost elasticity, with a greater reduction in costs when sales decrease than the increase in costs when sales increase. Second, the lower the cost will not appear as the obsolescence of assets rate increases in case that the concentration of an item of property, plant and equipment is high, and when sales decrease. The above result means that the obsolescence of assets rate acts as operating risk and thus operates resources flexibly according to changes in sales, but when the concentration of property, plant and equipment is high, the decision-making constraint make it difficult for the flexible operation.

The purpose of this paper is to verify the cost behavior of non-listed companies in Mongolia from 2013 to 2018. And we investigate the relationship between cost behavior and earnings management. Earnings management was measured using the Big-Bath and avoiding loss incentives. Big-Bath suspected firms report a very large loss and avoiding loss suspected firms have a bite profit. The results of this study are as follows. First, non-listed firms in Mongolia, operating costs(oc) and selling, general and administrative(sga) costs show the cost stickiness. Second, cost stickiness was different depending on the earnings management. The suspected avoiding loss firms have upward earnings management incentives, operating costs and sga costs all present anti-cost stickiness. The suspected big bath firms strengthen the cost stickiness of operating costs and sga costs. This study is meaningful in that it first analyzed the relationship between earnings management and cost stickiness of non-listed firms in Mongolia using empirical data. It will be meaningful in that it provides relevant information to those interested in research and investment.

The purpose of this study is to analyze how managers' reporting choices affect asymmetric cost behaviors in manufacturing firms in Korea and Japan. In order to analyze the contents, SG&A, COGS, and operating expenses (OE), which were the targets of the previous studies, were analyzed using the operating costs paid in cash (OC) and the operating expenses before depreciation (OEBD) proposed by Shust and Weiss (2014). The differentiation of cost behavior was analyzed. The analysis revealed, first, that both Korea and Japan showed the difference between cost behavior of OE and OC. Specifically, the cost stickiness of OC was higher than that of OE. In particular, it showed that Korea firms have a higher intensity of tangible fixed assets that are weakening the cost stickiness compared to Japanese firms. Second, the occurrence of depreciation costs weakens the cost stickiness in both countries. Lastly, the higher the debt ratio, the more aggressively the cost reduction of Japanese companies. We hope that this study will help to improve the relationship between the two countries at the academic level when the Korea-Japan relationship cools down.

This study examines the effect of the self-overviewing attributes derived from agency problem on the cost behavior in franchise industry. To solve the research problem, we developed the proxies for self-overviewing attributes of domestic franchise CEO and used Anderson et al. (2003)'s cost behavior model to test hypothesis. Moreover, we grouped the self-overviewing variables for additional test. We find that operating costs are more sticky for firms which present higher CEO's self-overviewing attributes in franchise industry. Second, we find that the greater the self-overviewing tendency, more strengthened cost stickiness when sales decrease. This study is meaningful in that we developed proxies for self-overviewing propensity, such as the hypodermic behaviors of franchise CEO, which have not been performed in previous studies, to enhance future studies of franchise CEO. Futhermore, we empirically provide the effects of CEO's self-overviewing attributes on the operating costs behaviors, suggesting useful information to franchise stakeholders such as prospective start-ups, franchisee and investors.
