We develop a cash management model in which firms face randomly occurred investment projects and retrieve investments upon the maturity of these projects. Using the Markov Decision Problem approach, we examine a control policy which dynamically adjusts the cash balance under the discounted cost criterion. The existence of an optimal policy is shown under some conditions. The optimal solution procedure is developed to find the optimal points and the optimal sizes for adjusting the cash balance. In numerical experiment, we investigate important structural properties of the optimal cash management policy.

2009년 7월부터 도입된 양육수당은 보육시설을 이용하지 않고 가정 내에서 양육되는 아동에 대한 형평성 차원에서 양육수당이 제공되는 것으로 보육시설을 이용하지 않는 국민기초생활수급자와 차상위 계층 2세 미만 영아에 대해 월 10만 원을 아동양육수당으로 제공하면서 시작되었다. 그러나 2013년에는 소득에 관계없이 만 0~2세의 아동을 대상으로 만 0세 20만 원, 만 1세 15만 원, 만 2~5세 10만 원의 지원금을 제공하기로 개정되었다. 2013년의 이러한 정책변화는 전년도인 2012년의 양육수당 정책과 비교해 볼 때, 760%의 재정 증액이 이루어진 것으로 그 지원의 확대 정도가 이례적으로 매우 큰 것을 알 수 있다. 본 논문에서는 이러한 양육수당의 급격한 확대에 주목하며 양육수당 정책형성과정에 대한 정책네트워크 분석을 시도하였다. 분석 결과, 지방선거, 총선 및 대선이 정책형성 과정 행위자들의 상호작용 및 네트워크 구조 등에 즉각적인 영향을 주었는데, 즉 정당 행위자들은 양육수당의 확대가 정당 행위자들의 이익(선거결과)에 직접적인 영향을 준다고 판단하고 있었다. 이러한 정책경쟁 과정에서 정부부처들과의 예산과 관련된 갈등은 오히려 논의를 다양화시켜 양육수당 논의는 활성화 되었다. 또한 총선 이후 새누리당의 공약에서 시작된 양육수당의 확대는 비슷한 복지 공약 등을 내세운 박근혜 후보가 대통령에 당선되면서 구체적으로 정책채택 단계로 접어들어 정책형성과정과 정책채택과의 밀접한 관계도 확인하였다.

Purpose - We examine the marginal value of cash in Korean retail firms, largely unexamined in literature. The marginal value of cash plays pivotal role in cash management policy; especially, a significantly low marginal cash value indicates substantial manager-shareholder conflicts. Research design, data, and methodology - We estimate marginal cash values by adopting the approach of Faulkender & Wang (2006). The sample of retail firms traded in Korean Stock Exchange from 1991 to 2013 is analyzed. Results - We estimate the marginal value of cash for the retail firms as 0.75, implying significant manager-shareholder conflicts. We find a lower marginal value of cash for financially constrained retail firms, contradicting existing theories. The marginal value of cash increases substantially after 2000s, suggesting severe agency conflicts in 1990s as a key reason behind our findings. Conclusions - Our findings support the substantial resource diversion problem in Korean firms and the agency theory of cash management policy. Our results argue against the widely accepted view focusing on implications of financial constraints, which highlights a need of new cash management theory.

Electronic cash affects central bank in many areas, in particular regarding the issuance of money, supervision of cashless payments, supervision of the banking system and monetary policy. The effects of electronic cash on central bank policies, the security and integrity of the payment system, and naturally also on single sector such as company engaged in the transport of money and valuables, depend mainly on the extent to which the new payment methods can replace cash. The possible development of electronic cash merits special attention from central banks for at least three reasons. First, central banks are concerned that the introduction of the new payment instrument should have no adverse effect on public confidence in the payment system and payment media. Second, although the substitution of electronic cash for other forms of money should not theoretically hamper central bank's ability to control the money supply, it might, however, have practial implications, at least in the long run, which need to be carefully examined. Third, because electronic cash may be used for payments of very small value, they have the potential, more than any other cashless instrument, to take over the role of notes and coins in the economy and, therefore, have implications for central bank's activities and revenues.

Prior literature expects a lower marginal cash value for weaker governance firms. We test this empirical hypothesis by using the sample of publicly traded Korean firms from 2005 to 2013. To measure the quality of governance structures, we employ the corporate governance scores provided by Korean Corporate Governance Services. The empirical model of Faulkender and Wang (2006) is adopted to estimate the marginal value of cash. Our empirical analysis shows a higher marginal value of cash for the good governance firms in the examination of the total governance score. This finding is consistent to the agency view of cash policy predicting a larger marginal value of cash for the firms with higher governance scores. However, this positive relationship is not robust for a subset of detailed governance scores; a lower marginal cash value is observed for the firms with better qualities of board structure, auditing, dividend policies. Moreover, our empirical analysis verifies a quite low level of marginal cash value for Korean firms, which supports the existence of severe agency conflicts in Korean corporations. Our results verify the significant role of agency conflicts between a manager and shareholders in the determination of marginal cash values in the Korean firms.

Purpose - This paper examines the explanatory power of the agency theory in the determination of cash holdings for Korean retail firms. If the agency theory holds, a firm with strong corporate governance structure tends to have low cash holdings. A strong governance structure makes the CEO of this firm to behave in the interests of shareholders and thus the CEO has low incentive to stockpile cash holdings, which can be easily diverted for the CEO's own managerial purposes. We investigate this relationship between corporate governance structure and cash holdings, by using corporate governance scores as a proxy variable that captures the effectiveness of corporate governance mechanism. Research design, data, and methodology - We adopt the sample of publicly listed retail firms in KOSPI market from 2005 to 2013. Financial and accounting statements are gathered from the WISEfn database. We also use the corporate governance scores published by Korean Corporate Governance Service. The relationship between the corporate governance scores and cash holdings is cross-sectionally estimated based on the ordinary least square method. This estimation method is widely accepted in the existing literature. The sample of large conglomerates, Chebol, and the remainder firms are separately examined as well, to account for the distinctive internal financing environment in these large conglomerates. Results - We mainly contribute to the extant literature by providing empirical evidence against the agency theory of cash policy. Unlike the prediction of agency theory, we confirm statistically insignificant or even positive correlations between the set of corporate governance scores and cash-asset ratios. Almost all the major corporate governance attributes including total score, shareholder rights, board structure, and the quality of information disclosure do not show negative correlations with cash holdings, which poses a strong challenge to the validity of the agency theory in the determination of retail firms' cash holdings. Conclusions - This study presents interesting empirical results with respect to the cash policy in Korean retail firms. Consistent to prior studies, I verify that the agency theory only limitedly explains the level of cash holdings. Future studies may obtain more robust results by examining a longer sample period.

Purpose - Prior theories expect a lower marginal value of cash for weak governance firms. To test this hypothesis, we examine the relationship between corporate governance structures and marginal cash values in Korean retail firms. Research design, data, and methodology - We estimate marginal cash values based on the model of Faulkender & Wang (2006). The retail firms listed in Korean Stock Exchange from 2005 to 2013 are analyzed. Corporate governance scores are provided by Korean Corporate Governance Services. Results - We show a higher marginal value of cash for the weak governance retail firms in terms of total governance score. Our analysis on a detailed set of governance scores generally confirms this tendency. Yet, a higher marginal cash value is obtained for the firms with better board structures and dividend policies. Conclusions - Our findings argue against the agency view of cash policy predicting a negative relationship between corporate governance scores and marginal cash values. A low marginal value of cash, widely observed in the sample firms, also supports severe resource diversion problem in Korean corporations.

본 연구는 1999년부터 2002년까지 지속적으로 많은 현금성 자산을 보유하고 있는 56개의 상장기업을 표본으로 하여 그 영업성과를 평가한다. 이를 위해 동종산업내의 유사한 자산규모를 가진 기업들과, 일시적으로 많은 현금자산을 보유한 기업들로 구성된 두 개의 비교표본을 이용한다. 결과에 따르면, 표본기업들의 향후 4년간, 즉 2003년부터 2006년까지의 영업성과는 두 비교표본에 비하여 평균적으로 우수함이 확인된다. 그리고 보유현금이 영업성과에 기여하는 정도는 소유구조와 정보비대칭의 정도에 따라 횡단면적 차이를 보인다. 먼저, 기업의 정보비대칭의 정도가 클 수록 현금보유가 영업성과에 긍정적인 영향을 미치는 것으로 확인되었는데 이는 현금자산이 정보비대칭에 따른 외부자본조달 비용의 추가부담을 감소시켰기 때문으로 판단된다. 한편, 외국인 지분이 큰 기업의 경우는 지속적인 현금보유가 영업성과 개선에 기여하지 못하는 것으로 나타났는데 이는 외국인 투자자들이 잉여현금문제를 감소시켜 현금자산의 기여도를 높이리라는 기대와는 일치하지 않는 결과이다. 오히려 외국인 투자자는 높은 배당을 요구하거나 적대적 M&A의 가능성을 높여 현금자산의 유용성을 저해한 것으로 생각된다. 반면, 최대주주 지분은 영업성과에 유의적인 영향을 보이지 않았다. 이 같은 결과는 보편적 기대와는 달리, 지속적인 현금자산 유지 정책이 평균적으로 영업성과에 긍정적인 영향을 가짐을 의미하며 그렇지만, 소유구조에서 기인하는 대리인 문제와 정보비대칭의 정도에 따라 그 유효성에는 횡단면적 차이가 있음을 시사하는 것이다.

Purpose - The purpose of this study is to examine whether the cash policies of retail firms listed on Korean stock markets are consistent with the evidence provided in the study of Almeida et al. (2004). Liquidity management is an important issue for financially constrained firms relative to financially unconstrained firms. Because there are few sources of external funding, the optimal liquidity policies of financially constrained firms should reflect their own earnings or cash inflows to create opportunities for current and future real investments. According to this simple idea, we estimate the sensitivity of cash to cash flows and simply check whether the estimated sensitivity to cash flows of the cash retained by constrained retail firms is greater than that of the cash retained by unconstrained retail firms. Through this work, we aim to explain why the cash policies of the retail firms listed on the Korean stock markets differ from those of listed manufacturing enterprises. Research design, data, and methodology - To explain a firm's cash holdings, we use only three explanatory variables: earnings before interest and taxes (EBIT), Tobin's q, and size. All the variables are defined as the value of the numerator divided by aggregate assets. Thanks to this definition, it is possible to treat all the sample firms as a single large firm. The sample financial data for this study are collected from the retail enterprises listed on the KOSPI and KOSDAQ markets from 1991 to 2013. We can obtain these data from WISEfn, the financial information company. This study's methodology has its origin in Keynes's simple idea of precautionary liquidity demand: When a firm faces financial constraints, cash savings from earnings or cash inflows become important from the corporate finance perspective. Following this simple idea, Almeida et al. (2004) developed their theoretical model and found empirical evidence that the sensitivity of cash to cash flows varies systematically according to different types of financing frictions. To find more empirical evidence for this idea, we examined the cash flow sensitivity of the cash held by Korean retail firms. Results - Through several robustness tests, we empirically showed that financially constrained Korean retail firms display significant positive propensity to save cash from earnings before interest and taxes, while the estimated cash flow sensitivity of the cash held by unconstrained retail firms is not significant. Despite the relatively low earnings of retail firms, their sensitivity is three times greater than that of manufacturing enterprises. This implies that Korean retail firms have greater intentions of facilitating future investments rather than current investments. Conclusions - The characteristics of the cash policies of Korean retail firms differ from those of manufacturing firms. This contrast may be attributable to industry-oriented policy planning, regulations, and institutional differences. However, the industrial policymakers should observe signals of the long-term growth options of retail firms based on their high propensity to save from their cash inflows.
