Even if a firm sets up a target leverage ratio to maximize its value, it may be deviated from the target ratio for various reasons when adjustment costs are substantial. On the other hand, the firm tries to revert to its target ratio when deviation costs are large enough. Adjustment costs includes not only explicit transaction costs affected by firm characteristics but also investment frictions, institutional arrangements, macroeconomic conditions, and etc. Since it is difficult to measure both adjustment and deviation costs, recent studies on leverage measure adjustment speeds using partial adjustment models which are adequate to reflect the dynamics of capital structure.The purpose of this study is to test the practical application of dynamic trade-off theory and non trade-off theory such as pecking-order and market timing based on the measurement of adjustment speeds of 387 Korean listed firms in the period of 2000-2014. Specially, we focus on the difference in adjustment speeds between large and small firms because firm size difference provides opportunity to discover the relative significance between adjustment costs and deviation costs. The adjustment speed of small firms is slower than that of large firms when small firms pay more transaction costs in financing. On the contrary, the adjustment speed of small firms is faster when they suffer more by being deviated from the target leverage ratio.Important empirical findings of this study can be summarized as follows. First, the adjustment speed is 0.51 when the book leverage ratio is used and 0.54 when the market leverage ratio is used. Such fast adjustments support the trade-off theory postulating that firms try to maintain the target leverage ratio. Second, the adjustment speed of small firms is faster than that of large firms, which indicates that deviation costs are more important than transaction costs. Third, this paper provides various evidence on the effects of firm characteristics on adjustment speeds classified by firm size. Fourth, various robustness tests increase the credibility of our results. Finally, we show that both the determinants of target leverage and the speeds of adjustment toward the target depend upon the choice of the book leverage ratio and the market leverage ratio.

The estimation of maintenance cost of information system so far has been conducted centered on the ordering body, so the problem of provider`s having to cover the cost due to small cost compared to the amount of work is not solved. This study is a base study for estimating the maintenance cost of information system centered on provider, and it deduces cost items of maintenance and suggests adjustment factors for adjusting the gap between the ordering body and provider regarding the maintenance cost. In order to deduce the cost items of maintenance, this study adds the activities of the provider for maintenance to the base study of cost factors regarding the existing maintenance activity, divides, and classifies them into the fixed cost and variable cost. In order to adjust the gap between the ordering body and provider regarding the maintenance cost, this study found the adjustment factors such as the code, utility, and components created by the automatic tool that was not included when estimating the maintenance cost centered on the ordering body. After examining and analyzing K Company`s data of maintenance performance for three years, it confirmed that the gap regarding the adjustment factors was about 13% in case of K Company.

원가의 하방경직성(cost stickiness)과 관련된 연구는 이를 실증적으로 검증한 Andersen et al.(2003)의 연구 이후 활발히 이루어져 왔다. 합리적인 의사결정 관점에서 원가의 하방경직성은 매출 감소에 대해 즉각적으로 잉여자원을 처분하지 않고 보유함으로써 발생하게 된다. 즉, 조정비용은 원가의 하방경직성을 야기 시키는 원인 중 하나이다. 본 연구는 횡단면적으로 하방경직성을 측정한 Andersen et al.(2003)의 모형과 달리 개별기업 수준에서 하방경직성을 측정한 Homburg and Nasev(2008)의 하방경직성을 산출하는 방법을 이용하여 하방경직적인 원가행태를 보이는 기업의 조정비용과 재무적 특성을 분석하였다. 연구결과, 첫째, 자산집중도, 종업원집중도, 매출의 변동성, 원가의 고정성은 양(+)의 값을 보고 하여 하방경직적인 원가행태를 보이는 기업의 조정비용은 높은 것으로 나타났다. 둘째, 하방경직성을 나타내는 기업의 비기대이익, 성장성, 유동비율은 양(+)의 값을 나타내었고, 부채비율은 음(-)의 값을 보여 주요 재무적 특성들을 확인하였다. 셋째, 코스피 기업과 코스닥 기업을 대상으로 평균 차이 검정을 분석한 결과 하방경직성, 조정비용, 재무적 특성은 차이가 있음을 발견하였다. 넷째, 하방경직적인 원가행태를 나타내는 기업의 조정비용과 재무적 특성은 시장에 따라 상이함을 제시하였다. 본 연구는 하방경직성을 나타내는 기업의 조정비용과 재무적 특성을 규명하였다는 점에서 의의가 있을 것이다. 아울러 시장의 성격이 상이한 코스피와 코스닥 기업을 구분하여 비교 분석함으로써 코스닥 시장의 원가행태에 대한 연구 토대를 마련했다는 점에서도 의미가 있다. After reporting the Andersen et al.(2003), the studies of cost stickiness are very active and most of them analyze the factors that affect the cost stickiness. In the reasonable decision perspectives, cost stickiness should happen to keep the unutilized resources instead of selling them promptly as sales go down. In other words, adjustment cost is one of the reasons to make the cost stickiness. This study shows the adjustments costs and financial characteristics of firm showing cost stickiness using the Homburg and Nasev(2008) model. The result of the study, asset intensity, employee intensity, sales volatility, and cost fixity are positive. It means that in showing cost stickiness firm has the high adjustment costs. Second, unexpected earnings, growth, and current ratio are positive, and debt ratio is negative. Hence, we know that showing the cost stickiness firms possess the financial characteristics. Third, this study finds out the difference of cost stickiness, adjustment costs. and financial characteristics between the listed companies in KOSPI and KOSDAQ. Finally, the adjustment costs and financial characteristics are different depending on the market. This study will be meaningful to provide the adjustment costs and financial characteristics of showing cost stickiness firms, and it compares the listed companies in KOSPI and KOSDAQ based on the market peculiarities. It will improve the relevance of management information. Moreover, it implies that only less cost decreasing gives awareness to the importance over the earning’s asymmetry.

環境紛爭調整法에 따른 분쟁해결과 ADR의 일반이론(Ⅱ)

김시철 한국환경법학회 2009 環境法 硏究 Vol.31 No.1

The Environmental Dispute Adjustment System (“EDAS”) stipulated in the Environmental Dispute Adjustment Act (“EDAA”) is a form of Alternative Dispute Resolution (“ADR”) handled by a division of the Administrative Branch. This particular dispute resolution mechanism followed in the EDAS, consists of several controversial aspects, when viewed in the light of various general principles that lies in the core of ADR. Though the main purpose of EDAS, which models after the Japanese Adjustment System for Grievances from Pollution, is to settle civil disputes arising in the environmental areas, when compared, the vast majority of EDAS cases in Korea relate to adjudicatory awards while mediation cases constitute overwhelming dispute resolutions in Japan. This, therefore, has drawn criticism concerning the Korean practice of dispute resolution in the environmental dispute setting, since it runs contrary to the very nature of ADR. Furthermore, in consideration of the general principles of ADR, the provisions of EDAA consist of various fundamental defects. In fact, due to the tendency of ‘under-litigation’ involving environmental disputes, to some extent, this requires a specific mechanism for resolution of such disputes. Under the current system of EDAS, however, the State provides public subsidy to litigants as a matter of fact, which may result in ‘over-litigation’ of disputed cases and actually create a converse effect. Though it may be inevitable to sustain the current system for the time being, for the future, the EDAS should be framed in order to minimize the total cost of resolving disputes. Since the total cost consists of both an ‘operation cost’ and an ‘error cost,’ to reduce the former cost, the latter cost is considered as a necessary trade-off. The EDAS, therefore, must be constructed in a way to minimize the sum of both costs accordingly. Until recently, the successful outcome of a mediation or an adjudicatory award within the EDAS has been considered as a formal consent agreement between the parties concerned, which is greatly similar to that of Japan. Nevertheless, because of the newly enacted statute, EDAA(amended by Act No. 8955 on Mar. 21, 2008, and effective on Sep. 22. 2008), the final outcome of EDAS now has the same effect as a consent judgment of a court. This raises doubts on whether the amendment of the statute can even be upheld as legitimate at all. Under the current Civil Procedure Act in Korea, consent judgments not only have the effect of an execution(enforcement power) but also the effect of a claim preclusion(res judicata). When compared, the Korean consent judgment system is somewhat different from the German system, which only has the effect of execution(enforcement power) but not of claim preclusion. The constitutionality of the statute must also be strictly scrutinized since outcomes of the ADR conducted by the Administrative Branch have the similar effect of a consent judgment. Even from the standpoint of democratic legitimacy, the Korean EDAS is relatively inferior to the Japanese system. Thus, it seems unreasonable to produce the outcomes of EDAS have the similar effect of a consent judgment. Furthermore, in light of the precedents of the Korean Constitutional Court, controversy surrounding the constitutionality of the provisions on the effect of EDAS or Ex Officio Mediation system still remains as an important issue to be considered. The very nature of the ADR must be emphasized that respects the parties’ autonomy involving each dispute, in order to establish a dispute resolution system that is based on sound ADR principles. From another standpoint, the success of EDAS system depends on the extent of reducing the error costs associated with the disputes resolutions. Therefore, in addition to reviewing the empirical research conducted in the U.S. or Japan for guidance in improving the current EDAS system, attempts to narrow the gap between the decisions of the...

식중독의 사회경제적 비용추정: 삶의 질 개념을 적용한 질병비용추정법을 이용하여

신호성,이수형,김종수,김진숙,한규홍,Shin, Ho-Sung,Lee, Sue-Hyung,Kim, Jong-Soo,Kim, Jin-Suk,Han, Kyu-Hong 대한예방의학회 2010 예방의학회지 Vol.43 No.4

Objectives: This study estimated the annual socioeconomic costs of food-borne disease in 2008 from a societal perspective and using a cost-of-illness method. Methods: Our model employed a comprehensive set of diagnostic disease codes to define food-borne diseases with using the Korea National Health Insurance (KNHI) reimbursement data. This study classified the food borne illness as three types of symptoms according to the severity of the illness: mild, moderate, severe. In addition to the traditional method of assessing the cost-of-illness, the study included measures to account for the lost quality of life. We estimated the cost of the lost quality of life using quality-adjusted life years and a visual analog scale. The direct cost included medical and medication costs, and the non-medical costs included transportation costs, caregiver's cost and administration costs. The lost productivity costs included lost workdays due to illness and lost earnings due to premature death. Results: The study found the estimated annual socioeconomic costs of food-borne disease in 2008 were 954.9 billion won (735.3 billion won-996.9 billion won). The medical cost was 73.4 -76.8% of the cost, the lost productivity cost was 22.6% and the cost of the lost quality of life was 26.0%. Conclusions: Most of the cost-of-illness studies are known to have underestimated the actual socioeconomic costs of the subjects, and these studies excluded many important social costs, such as the value of pain, suffering and functional disability. The study addressed the uncertainty related to estimating the socioeconomic costs of food-borne disease as well as the updated cost estimates. Our estimates could contribute to develop and evaluate policies for food-borne disease.

Capital Structure Adjustment in Korean Retail Firms

이정환,김상수 한국유통과학회 2017 유통과학연구 Vol.15 No.11

Purpose - Capital structure adjustment costs influence the test of the standard trade-off theory of capital structure. We investigate whether there exist economically significant capital adjustment costs in the Korean retail industry. Research design, data, and methodology - This paper adopts the model of Leary and Roberts(2005) to obtain the hazard rate of capital structure variations. The retail firms traded in the KOSPI and KOSDAQ markets are analyzed from 2000 to 2016. Results - The empirical analysis shows infrequent capital structure adjustments in the Korean retail firms. The duration analysis emphasizes that the fixed adjustment cost plays an important role in the determination of capital structure adjustments for the Korean retail firms. Yet, even after taking account of infrequent capital structure adjustments, the trade off theory only weakly explains the capital structure variations of the Korean retail firms. Conclusions - This paper confirms the existence of capital structure adjustment costs for the Korean retail firms. Our results argue for the significance of fixed adjustment costs in capital structure adjustments. Such emphasis on the fixed cost is inconsistent with the existing studies. The trade off theory does not successfully explain capital structure policy in the Korean retail firms even after considering adjustment costs.

Speed of Adjustment and Leverage Deviation - Cost of Equity Nexus: Evidence from Emerging Markets and Crisis

Akbar Aldino Karpates,Viverita Viverita 사람과세계경영학회 2022 Global Business and Finance Review Vol.27 No.6

Purpose: This study investigates the impact of leverage deviation on the cost of equity under the specifically mentioned condition in ASEAN-5 considering the global financial crisis and the sensitivity of the cost of equity on leverage deviation. Design/methodology/approach: This study employs the Generalized Least Square (GLS) model and the dynamic panel estimation based on the two-step difference GMM to analyze the data. Findings: The regression analysis found deviated from the target leverage impact unfavorably on the firm's cost of equity. The results also show that the more sensitive the cost of equity is to the leverage deviation from the target, the faster the adjustment. However, firms will adjust their capital structure for a lower cost during the crisis. Additionally, it shows a compelling behavior in the relation between the sensitivity of the cost of equity to leverage deviation on the leverage speed of adjustments. Research limitations/implications: The higher sensitivity of the cost of equity is to the leverage deviation from the target, the faster the adjustment. It implies that the disregard of heterogeneity in SOA will mislead the adjustment period to the target leverage. Originality/value: Using manually collected data, this study provides empirical evidence on the importance of leverage deviation and the sensitivity of the cost of equity and the speed of adjustment to the target debt level to analyze capital structure decision in an enormous leverage usage in ASEAN. Second, this paper presents new evidence of the effect both in normal economic conditions and crisis periods, which is rarely examined in the ASEAN emerging market.

미국 반덤핑 조사에서 원가 미만 판매 테스트의 공정성 연구 - 원가와 내수 판매가격 간 공정한 비교 -

송은엽,이지은 무역구제학회 2022 무역구제연구 Vol.0 No.66

As the dumping margin is calculated through the comparison between the export price and the normal value, the fair comparison between the two prices is the most essential factor in calculating the reasonable dumping margin. Accordingly, the WTO Anti-Dumping Agreement and the U.S. Customs Act specifically stipulate the definition and factors of the like product and the two prices are compared based on the product characteristic value of CONNUM in consideration of factors that may affect sales price and cost. If the factors to be considered are not fully reflected in CONNUM, the level of trade adjustment may be applied to solve the problem of distortion of fairness. However, in the case of a sales-below-cost test, there is no legal provision to provide a fair comparison, and the U.S. Department of Commerce’s guideline to report only one weighted average cost per CONNUM limits the possibility of various costs depending on production facilities, regions, etc. within the same CONNUM. Therefore, this study discussed a fair comparison between export prices and normal values and reviewed the definition of normal values and production costs subject to sales-below-cost tests. Also, upon analysis of the case related to cost adjustment, this study proposed the limitations of fair comparison between normal value and production cost and the need for cost adjustment. 덤핑마진은 수출가격과 정상가격 간의 비교를 통해 산출되므로 두 가격간의 공정한 비교는 정확한 덤핑마진 산정에 있어 가장 기본이 된다. 이에 WTO반덤핑협정 및 미국 관세법 등에서 수출가격의 비교대상이 되는 동종물품의 정의 및 고려 요소에 대해 구체적으로 명시하고 있으며, 판매가격과 원가에 영향을 미칠 수 있는 요인들을 고려하여 CONNUM이라는 제품 특성치를 기준으로 두 가격을 비교하도록 규정하고 있다. 고려해야 하는 요인들을 CONNUM에 온전히 반영하지 못한 경우, 공정성이 왜곡되는 문제를 해결하기 위해 수출시장과 내수시장의 거래단계 간의 차이를 조정하는 장치가 마련되어있다. 그러나 정상가격과 생산원가를 비교하는 원가 미만 판매 테스트의 경우, 공정한 비교가 이루어질 수 있도록 규정하는 법률 조항이 없을 뿐만 아니라 CONNUM 한 개당 한 개의 가중평균 원가만을 보고하도록 하는 미 상무부의 규정은 동일한 CONNUM 내에서도 생산설비, 지역 등에 따라 다양한 원가가 존재할 수 있는 가능성을 제한함에 따라 정상가격과 생산원가 간의 공정한 비교가 이루어지지 못하고 있다. 이에 본 연구는 수출가격과 정상가격 간의 공정한 비교에 대해 논의하고 원가 미만 판매 테스트의 대상이 되는 정상가격과 생산원가의 정의에 대해 검토하였다. 이후 원가조정과 관련한 사례를 통해 정상가격과 생산원가 간의 공정한 비교가 이루어지지 못하는 한계점과 원가 조정의 필요성에 대해 제언하였다.

Junseok Bae,Pratyush Shahi,Sang-Ho Lee,Han-Joong Keum,Ju-Wan Seok,Yong-Soo Choi,Jin-Sung Kim 대한척추신경외과학회 2025 Neurospine Vol.22 No.1

Objective: To analyze costs and cost-effectiveness of transforaminal endoscopic thoracic discectomy (TETD) for the treatment of symptomatic thoracic disc herniation (TDH) and compare it with open microdiscectomy (MD). Methods: This retrospective cohort study included patients who underwent TETD or MD for symptomatic TDH and had a minimum follow-up of 1 year. Cost analysis included di rect costs (primary and secondary hospital costs), indirect costs (lost wages due to work ab sence), total costs (direct + indirect), and cost-effectiveness (cost per quality-adjusted life year [QALY] and incremental cost-effectiveness ratio [ICER]). Clinical outcomes included patient-reported outcome measures (Oswestry Disability Index [ODI], 36-item Short Form health survey [SF-36]), QALY gained, and reoperation and readmission rates at 1 year. TETD and MD groups were compared for outcome measures. Results: A total of 111 patients (57 TETD, 54 MD) were included. The direct ($6,270 TETD vs. $7,410 MD, p<0.01), indirect costs ($1,250 TETD vs. $1,450 MD, p<0.01), total costs ($7,520 TETD vs. $8,860 MD, p <0.01), and cost per QALY ($31,333 TETD vs. $44,300 MD, p <0.01) were significantly lower for TETD compared to MD. ICER of TETD was found to be -$33,500. At 1 year, TETD group showed significantly greater improve ment in ODI (46% vs. 36%, p < 0.01) and SF-36 (64% vs. 53%, p < 0.01) and significantly greater QALY gained (0.24 vs. 0.2, p < 0.01) compared to MD group. No significant differ ence was found in reoperation and readmission rates. Conclusion: TETD demonstrated significantly better clinical outcomes, lower overall costs, and better cost-effectiveness than MD in appropriately selected patients of symptomatic TDH.

Economic Evaluation of Add-on Levetiracetam for the Treatment of Refractory Partial Epilepsy in Korea

Guk-Hee Suh,Sang Keol Lee 대한신경정신의학회 2009 PSYCHIATRY INVESTIGATION Vol.6 No.3

Objective: This study estimated the expected cost-effectiveness ratio expressed as the incremental cost per seizure-free day (SFD) gained and the incremental cost per quality adjusted life year (QALY) gained when using levetiracetam (LEV) as add-on therapy from a third-party payer perspective. Methods: A 1-year dose-escalation decision-tree model comparing LEV plus standard therapy (ST) with ST alone was designed to combine transition probabilities, costs and outcomes. The short-term outcomes and probabilities were derived from a prospective, openlabel clinical trial with 100 Korean adults with refractory partial epilepsy. All data for the direct medical costs were derived from Korean cost data extracted from reports published by the National Health Insurance Corporation. Results: The average gain in SFDs attributed to LEV add-on was 18.3 days per patient per year and the incremental cost-effectiveness ratios (ICERs) for LEV add-on were US$ 44 per SFD per patient and US$ 11,084 per QALY gained. All sensitivity analyses showed that the model was robust to the assumptions made. Conclusion: The economic evaluation indicates that, given a wide range of assumptions, the increased cost of treating patients having refractory partial epilepsy with LEV may be partially offset by a reduction in other direct medical costs. This reduction is a consequence of an increase in the number of SFDs and improved quality of life.
