본 연구의 목적은 발생한 거래에 대해 적합한 회계 계정을 선택하는 예측 모델을 생성하는 것이다. 이를 통해 단기적으로 보조 수단으로 활용하여 회계 전표 승인에 대한 소요 시간을 단축하거나, 장기적으로 손익계산서가 일정 오차율 이내에서 자동으로 빠르게 작성됨으로써 재무 정보의 적시성을 올려주고, 기업의 실적을 나타냄에 있어 개별 담당자의 주관이 개입될 여지가 줄어든다는 면에서 재무 정보의 객관성을 올려줄 것으로 기대한다. 제안하는 모델은 비용 전표 이력의 적요를 자연어 처리하고 학습한 모델을 통해 1 차(공시용) 비용 계정을 분류한다. 분류 결과를 범위로 활용하는 기계 학습을 활용하여 좀 더 세밀한 범위의 2 차(관리용) 비용 계정을 분류하였다.

In this study, we investigated public announcements of stock splits using the Korean Stock Market data from 2000 through 2007. The purposes of this study are to examine whether stock splits have the information contents in the Korean capital markets, and to investigate the possible cause of the market reactions. We measured the market reactions with abnormal returns, cumulative abnormal returns and cumulative average abnormal returns. For the purpose, two specific hypotheses were tested. One is 'Signalling Effects' where stock splits function as a signal through which managers transmit a favorable information for investors. The other is 'Liquidity Effects' where stock splits increase the trading convenience. We have th following results. Firstly, positive market effects were found when stock splits were announced. Secondly, there was difference in trading convenience between the high and the low split ratios. Finally, the long term performance through stock splits in the Korean capital markets was not significant.

Throughout this research course, we have analyzed the financial situation of more than 2,700 companies using credit evaluation disclosures from 2017 to 2019. The population was gathered based on the certification of Ppuri companies and Ppuri Expertise companies through the Korea National Ppuri Industry Center, accompanied by the NICE credit evaluation index. For the first time in Korea, we wanted to look at growth, profitability, and stability through financial analysis of the Ppuri industry. Through an indepth analysis, we identified operating income (rate), net income (rate), asset size, and debt ratio, along with three years of Ppuri company workers and total sales fluctuations, and looked at the financial structure per capita. In addition, financial status per person was compared by dividing Ppuri companies into six groups by employee size. Groups were 10 or fewer people, 11 to 20 people, 21 to 50 people, 51 to 200 people, 201-300 people, and 300 or more people; single individual companies were excluded for research convenience. Overall, the financial situation of Ppuri companies was judged to be in a very bad downturn, and financial indicators deteriorated over the course of the three years of investigation. In particular, the smaller the number of employees, the greater the financial fluctuations were and the worse the situations were. Among Ppuri companies, the casting industry, which is the technical starting point for the value chain of the industry, was found to also be in a very bad state, with continued workforce declines, total assets and sales reductions at severe levels, and operating income (rate) and net income (rate) also very poor. This is why we need a suitable and feasible policy direction, something that is difficult but must be allowed to develop.

This study aims to determine whether ESG performance positively affects foreign ownership for listed firms that publish sustainability reports. Furthermore, we test whether the disclosure of environmental information in the sustainability report in accordance with the TCFD recommendations moderates the relationship between ESG performance and foreign ownership. The results of the empirical analysis are as follows. First, there is a positive correlation between ESG performance in a given year and foreign ownership in the following year, i.e., the higher a firm's ESG performance, the higher its foreign ownership. Second, the presence of environmental disclosure in accordance with the TCFD recommendations positively moderates the relationship between ESG performance and foreign ownership, i.e., environmental disclosure in accordance with the TCFD recommendations strengthens the positive relationship between ESG performance and foreign ownership. In conclusion, this study shows that foreign investors invest more in companies with better ESG performance, and the effect is stronger for companies that disclose environmental information in accordance with TCFD recommendations.

Using the financial institutions that have adopted performance-based stock option plan, this paper examines whether performance-based executive stock options improves effectively firm value. Over the period 2002~2005, we investigate short-term and long-term effects of the performance-based stock options on stock price. The empirical results are summarized as follows. First, the announcement of plain vanilla stock options generates no significant effects on firm value. Meanwhile, the announcement of performance-based stock options results in negative and significant abnormal returns, which is contrary to the expectation. In addition, we find that there are strong, significant and negative announcement effects when banks grant performance-based stock options. Secondly, there is no significant difference between the long-term performance of the sample granting stock options and that of the benchmarks, which is similar to the findings of the previous research. Also, we fail to get any evidence that performance-based stock option awards have improved the long-term firm value.

기존연구에 의하면 무상증자의 공시는 공시기간 중 정(+)의 가격효과를 초래하는 것으로 나타나고 있다. 무상증자에 대한 이러한 시장의 호의적인 반응을 설명하기 위해 여러 가설이 제기되어 왔으며, 그 중 무상증자는 좋은 내부정보를 외부에 신빙성 있게 전달하는 신호기제가 될 수 있다는 신호가설이 특히 지지를 받고 있다. 그런데 짧은 공시기간 중의 정(+)의 주가반응만을 보고 신호가설이 지지된다고 단정짓는데는 무리가 있다. 본 연구에서는 과연 신호가설이 주장하는 것처럼 무상증자가 사업기회의 확대, 미래현금흐름의 증대, 추후 차입여력의 증대를 가져오는가를 더 면밀히 검증하기 위하여 무상증자 실시기업의 장기성과를 조사하였다. 본 연구의 특징은 (1)공시기간 이후의 1년 이내의 기간에 중점을 둔 대부분의 기존연구와 달리 증자 후 36개월간의 장기성과를 측정하였으며, (2)주가수익률 자료와 회계자료를 동시에 이용하여 장기성과를 조사하였고, (3)장기 초과수익률 측정과 검증에 있어 통계적 오류가 있는 누적초과수익률(CAR)을 보완하기 위해 매입보유초과수익률(BHAR)을 사용했으며, 이를 위해 엄격한 기준을 적용하여 표본기업과 비교기업을 선정하였다는 데 있다. 실증분석 결과 신호가설을 지지하는 증거는 발견하지 못하였으며 오히려 무상증자 실시기업이 시장평균 또는 비교기업인 비증자기업에 비해 장기적으로 주가수익률 및 영업성과에 있어 저성과를 보이는 증거를 상당 수 발견하였다. 구체적으로 동일가중평균수익률로 조정한 보유기간 초과수익률의 경우 증자 후 1개월에서 24개윌까지의 BHAR이 5% 미만 수준에서 부(-)의 값을 보였으며, 비모수통계치를 사용할 경우 $1{\sim}36$개월까지의 전기간에서 유의한 부(-)의 저성과를 보이고 있다. 또한 영업성과면에서도 증자기업이 비증자기업에 비해 증자 후 수익성과 현금흐름이 저조하게 나타나고 있다.해 현물시장의 수익률, 변동성이 높은 것으로 나타났으나, 변경후에는 현물시장에 비해 선물시장의 수익률 변동성이 높은 것으로 나타났다. VAR 분석에 의하면 변경후가 변경전에 비하여 선물이 현물을 선도하는 시차가 다소 커진 것으로 나타나 현물시장과 선물시장이 동시에 가격제한폭 확대후에 비효율적으로 되었다는 의미로 판단된다.기간에서는 선물의 15분 선도효과와 현물의 1분 선도효과가 발견되어 선물의 선도효과가 지배적임을 발견하였다.적 일정하게 하는 소비행동을 목표로 삼고 소비와 투자에 대한 의사결정을 내리고 있음이 실증분석을 통하여 밝혀졌다. 투자자들은 무위험 자산과 위험성 자산을 동시에 고려하여 포트폴리오를 구성하는 투자활동을 행동에 옮기고 있다.서, Loser포트폴리오를 매수보유하는 반전거래전략이 Winner포트폴리오를 매수보유하는 계속거래전략보다 적합한 전략임을 알 수 있었다. 다섯째, Loser포트폴리오와 Winner포트폴리오를 각각 투자대상종목으로써 매수보유한 반전거래전략과 계속거래 전략에 대한 유용성을 비교검증한 Loser포트폴리오와 Winner포트폴리오 각각의 1개월 평균초과수익률에 의하면, 반전거래전략의 Loser포트폴리오가 계속거래전략의 Winner포트폴리오보다 약 5배정도의 높은 1개월 평균초과수익률을 실현하였고, 반전거래전략의 유용성을 충분히 발휘하기 위하여 장단기의 투자기간을 설정할 경우에 6개월에서 36개월로 이동함에 따라 6개월부터 24개월까지는 초과수익률이 상승하지만, 이후로는 감소하므로, 반전거래전략을 활용하는 경우 주식투자기간은 24개월이하의 중단기가 적합함을 발견하였다. 이상의 행태적 측면과 투자성과측면의 실증결과를 통하여 한국주식시장에 있어서 시장수익률을 평균적으로 초과할 수 있는 거래전략은 존재하므로 이러한 전략을 개발 및 활용할 수 있으며, 특히, 한국주식시장에 적합한 거래전략은 반전거래전략이고, 이 전략의 유용성은

This study investigated the effect of tender-offer on the value of the firms in Korea. For this purpose, the study applied an event study methodology to 55 cases(bidding firm : 26, target firm : 39) of tender-offer and 164 cases(bidding firm : 144, target firm : 20) of merger announcements made between January 1st, 1994 and September 30th 2004. We found the following results. For tender-offer announcements, there was a significant increase in target firm's value while there was no significant change in bidding firm's value. In contrast, for merger announcements, there was a significant increase in bidding firm's value while there was no significant change in target firm's value. In addition, the synergy effect of tender-offer was higher than that of merger. The results support the Berkovitch and Khanna(1991)'s prediction that bidding firms choose tender-offer rather than merger in the presence of higher synergy profit from M&A.

Since convertible debt has both characteristics of stocks and bonds, its issuance can be related to both interests of stockholders and bondholders. Nevertheless, the existing studies focused mainly on the wealth effect on stockholders. In this paper we revisit the hypotheses on the issue of convertible debt especially from the viewpoint of a firm's growth, by making an additional investigation into bondholders' wealth effects. We find that stockholders' wealth increases with bondholders' wealth in the firm whose book-to-market ratio is low and thus is considered a growth firm. This finding seems consistent with the hypothesis in which the issue of convertible debt mitigates the agency cost of debt in the high-growth firm.

Environmental accounting identifies and measures environmental costs and provides them to interested parties of corporation. The purposes of this study are as follows: First, it investigates the method of measurement and the timing of recognition of environmental costs. Second, it suggests the method of disclosure of environmental costs. In order to accomplish these objectives, this study reviewed relevant literature and studies in advanced countries and Korea. The main results of this study can be summarized into four points: (1) environmental costs are classified into environmental pollution cost and environmental pollution prevention cost, by considering the sources of occurrence of, the functions of and the types of environmental costs. (2) the methods of measurement of environmental costs are various but they almost all subjective and arbitrary. So an accurate measurement of environmental cost is actually difficult. (3) According to the accrual basis, environmental costs are recognized respective to prior period adjustments, expenses or losses of the current period and the assets of the next period. (4) There are 3 methods of disclosure of environmental costs: an extension model of financial statements, a compromise model, and an original model. An extension model financial statements is easy to apply in business practice because it discloses environmental costs by adding accounts into the framework of a traditional accounting system or supplementary reports. This research can contribute to the establishment of accounting standards for environmental costs in Korea.

In this paper, we have studied the impact of adopting XBRL (eXtensible Business Reporting Language) on information asymmetry in capital markets with the additional research on the usefulness of XBRL data how to improve the quality of accounting information. From the Kosdaq XBRL service, the samples are selected including 38 adopted companies and the 30 non-adopted companies for the paired analysis. The daily stock return volatility (VOLA) as independent variable and other several controlling variables have been added for the regression analysis to measure the impact on information asymmetry in capital markets. he analytical result indicated that the asymmetry hypotheses that XBRL data will give a significant impact on the capital market and will reduce the volatility, which are expected in the hypotheses. This is the first analytical research on the capital market and its impacts to the capital market from adopting XBRL based accounting information. Additionally, the analysis showed the impacts on the reporting cycle of accounting information and its usefulness of accounting data itself.
