현금흐름과 발생액 및 구성요소들이 현금흐름의 지속성과 기업가치에 미치는 영향

박창래,이상희,Park, Chang-Rae,Lee, Sang-Hee 한국산학경영학회 2009 산학경영연구 Vol.22 No.2

본 연구의 목적은 이익의 구성요소인 현금흐름과 발생액 그리고 현금흐름 요소 및 발생액의 요소가 현금흐름의 지속성과 기업가치에 미치는 영향을 조사하였다. 차기의 현금흐름과 재무제표공시시점 월말의 종가 각각을 종속 변수로 하고 당기의 현금흐름과 현금흐름의 구성요소, 그리고 발생액과 발생액의 구성요소를 독립변수로 하는 4개의 모형에 대하여 회귀분석을 실시하였다. 1980년에서 2006까지 증권거래소에 상장된 12월 결산 제조기업을 대상으로 분석한 결과는 다음과 같다. 현금흐름과 발생액은 현금흐름의 지속성과 기업가치 평가에 유의적인 관계를 보이고 있으며 현금흐름이나 발생액 보다는 현금흐름의 요소나 발생액의 요소가 현금흐름의 지속성과 기업가치평가에 미치는 영향이 더 컸다. 그리고 현금흐름의 요소와 발생액의 요소 중 일부는 현금흐름의 지속성이나 기업가치평가에 있어서 서로 다른 영향을 미치는 결과를 보였다. 따라서 현금흐름과 발생액을 현금흐름의 지속성과 기업가치 평가와 관련된 의사결정에 활용할 경우 총액보다는 각 요소별로 고려할 필요가 있으며, 현금흐름 예측시와 기업가치 평가에 있어서 각 요소를 달리 고려할 필요가 있음을 보여준다. The purpose of this article is to investigate the effects of cash flow and accrual, which are the elements of earnings, and those of the elements of cash flow and accrual on the consistency of cash flow and firm's value. We analyzed 4 kinds of regression models, of which the independent variables are this period's cash flow, the elements of cash flow, accrual, and the elements of accrual, and the dependent variables are the next period's cash flow, and the stock price at the end of financial statements disclosure months, respectively. The sample firms were the manufacturing companies listed on the Stock Exchange 1980 through 2006, of which the fiscal year ended in December. And, the results of the analyses are as follows: Cash flow and accrual are shown to have significant relationships with cash flow consistency and the evaluations of firms' value. And, the elements of cash flow or accrual proved to have more influence than the total amount of them, on cash flow consistency and the evaluation of firms' value. Also, the results present that some of the elements of cash flow and accrual differently affect cash flow consistency and the evaluation of firms' value. Accordingly, this study indicates that each of the elements of cash flow and accrual needs to be considered respectively rather than the total amount of them, in the case that cash flow and accrual are used in the decision-making concerned with the forecast of cash flow and the evaluation of firms' value. This study also shows that each element of cash flow and accrual needs to be used differently for cash flow forecast and the evaluation of firms' value.

When the financial accounting regulations are established by governmental agency, the accounting regulation change may have two aspects of effect. The one is the effect of regulation itself. The other is symbolic meaning effect of governmental regulation. This study is to investigate the information content of the mandated disclosure of consolidated financial statements in these two aspects. First, I investigated the disclosure expansion effect by the comparison of the information content of parent companies with control companies which had no disclosure duty. Second, I investigated the symbolic meaning effect of governmental regulation by the comparison of the information content of members in Big Group Companies with non-members. The empirical test results are as fellows. First, there is no significant difference in information content between parent companies and non-disclosure duty companies. And there is no significant difference between already disclosure firms and non-disclosure firms. This results show that the disclosure expansion effect doesn`t exist. Second, except the case of disclosure duty companies, there is significant difference in information content between members in Big Group Companies and non-members. And the members are lower in CAR than non-members. This shows that symbolic meaning effect of governmental regulation change exists.

Hospitals have been very susceptable to changes in external environment. Accordingly, they have been experiencing great financial difficulty due to low insurance rates and increasing competition. As a remedy, hospitals have attempted to use computer in a strategic manner. Such system is called strategic information system(SIS), and order communication system(OCS ) is an example of SIS in hospital setting. While OCS has known to be effective in reducing waiting time for outpatients, many hospitals are reluctant to introduce this system mainly because there are no real data or methods for justifying the cost of the system. Cost-benefit analysis has been traditionally used for such purpose, but this method deals with limited portion of benefits and therefore not very useful for analyzing the economic feasibility of SIS. In this paper, information economics tools which expand cost with value was used to analyze the economic feasibility of OCS. To assist the analysis, financial simulation model was developed using simulation package, called IFPS(Interactive Financial Planning System).

Hospitals are experiencing an increasing amount of financial difficulty due to government control of hospital rates since national health insurance has been implemented. The decision support system (DSS) was developed to provide cost and revenue information for the services rendered by each department in an effort to reduce costs. This information may be used to identify the causes of financial loss if cost exceeds revenue and to conduct variance analysis or portfolio analysis to improve financial situation of hospitals. The DSS was developed using a micro-mainframe interface approach where the mainframe computer collects and summarizes daily cost and revenue data and the micro computer computes the cost for each department. The significances of this paper are to determine the cost allocation basis and methods which are suitable to Korean situation and to apply DSS technology to the cost analysis.

확률 변동성 곡면의 구축과 활용방안에 관한 연구

본 연구는 Heston(1993)모형과 Dupire(1994)모형을 이용하여 내재변동성 곡면(implied volatility surface)과 국소변동성 곡면(local volatility surface)을 구축하는 방법에 대해 연구하였다. 오랫동안 블랙-숄즈 공식의 문제점으로 지적되어온 상수 변동성(constant volatility)을 이용한 옵션가격결정모형의 대안으로 변동성 왜도와 기간구조를 반영한 정교한 확률변동성 곡면을 구현하는 방법을 기술하고, 금융업계의 현실을 반영하여 그 활용방안을 고찰해 보았다. 변동성 곡면을 구축하는 방법으로는 Heston(1993)모형으로 장외옵션 자료(장내옵션도 활용)를 활용하여 장내옵션만으로 구축이 가능하지 않은 머니니스와 긴 만기를 갖는 유럽형 옵션의 가격을 계산하였으며, 이 유럽형 옵션 가격에서 내재변동성을 계산하였다. 또한, 주가연계증권(ELS)의 가격결정과 헤징에 사용하기위해 위와 같은 방식으로 계산된 내재변동성을 이용하여 Dupire(1994)모형으로 국소변동성 곡면(local volatility surface)을 구현하였다. 변동성 곡면이 금융업계에서 주가연계증권(ELS)의 가격결정과 헤지운용에 활용도가 높아지고 있어, 기존의 역사적변동성으로 평가되던 상수 변동성을 변동성 곡면으로 대체할 경우 시장 내재변동성이 반영된 정교한 헤지운용 성과를 기대할 수 있을 것으로 판단된다. 아울러, 국내외 ELS발행사가 투자자의 환매요청에 따라 제시하고 있는 ELS 환매가격과 평가가격과의 괴리를 줄일 수 있어, 유가증권을 평가하는 채권평가사의 ELS시가평가 발전에 기여 할 것으로 판단된다. We study the construction of implied volatility surface and local volatility surface using Heston(1993) and Dupire(1994) model, respectively. Practitioners have been aware of the drawback of Black-Scholes option pricing model when it comes to the assumption of constant volatility. We contemplate sophisticated construction methods reflecting volatility skew and term structure in real financial markets. Heston(1993) model enables us to calibrate implied volatility surface which has long term maturity and deep out of the money strikes using listed and OTC derivatives including hybrid options. We also make it into the local volatility surface which can be used for pricing and hedging ELS(Equity-Linked-Securities) products following Dupire(1994) model. There is a growing number of the utilization of volatility surface in hedging and pricing ELS products in financial markets. We expect that exploiting volatility surface could give us operation benefits comparing with the use of constant volatility. Furthermore, it would contribute to the advancement of the bond pricing companies by filling the gap between redemption price and evaluation price of the ELS.
