우리 나라의 금융기관들은 금융환경(金融環境)의 급격한 변화 속에서 일대 전환기를 맞고 있다. 대내적으로는 금리자유화를 비롯한 금융자율화(金融自律化)의 추진, 금융산업의 개편 등의 금융구조 조정이 진행되고 있고, 대외적으로는 국내금융시장에 대한 개방압력(開放壓力)이 가중되고 있다. 본 연구의 목적(目的)은 이상의 다양한 금융환경의 변화 중에서 1991년과 1993년에 실시된 1,2단계 금리자유화조치가 은행의 경영위험에 어떠한 영향을 미쳤는지를 증권시장(證券市場)의 반응을 통하여 규명하고자 한다. 구체적으로 일반적인 예상과 같이 금리자유화로 인하여 은행의 위험이 증가하였는지 아니면 금리자유화가 은행의 자금조달과 운용에 있어서 자율성과 유연성을 확보해 주어서 오히려 은행위험을 감소시켰는지를 실증적으로 검증한다. 주가자료를 이용하는 증권시장의 반응을 통한 은행위험의 분석은 은행에 관련된 재무정보를 신속하고 충분히 반영하는 효율적 시장이며 회계자료를 이용하여 은행위험을 추정하는 방법이 부적절하다는 가정하에서 합리화된다. 은행 위험은 은행감독 당국의 관심대상인 총위험과 은행주식 투자자의 관심대상인 체계적 위험의 두요소를 대상으로 한다. 본 연구의 증권시장반응을 통한 실증분석결과에 의하면 금리자유화조치 이후 은행의 위험은 예상과는 달리 증가하지 않은 것으로 나타났다. 은행총위험은 증가하지 않았으며 체계적 위험은 오히려 2차 금리자유화 이후 하락하는 결과를 보여준다. 이는 금리자유화 조치가 은행의 자금조달과 운영에 있어서 운신의 폭을 넓혀줌으로써 금리 변동폭 증대로 인한 위험증가를 상쇄함을 의미한다. 이러한 결과는 미국의 금리자유화조치에 관련된 대부분의 연구결과와 일치한다. 또한 위험은 개별은행의 재무특성에 따라서 상이한 변화를 보여주었다. 특히 자산규모가 작은 후발은행의 경우 자금조달과 운영의 측면에서의 제한이 완화됨으로써 위험이 감소함을 보여준다. 따라서 정부당국자는 금리자유화의 긍정적 효과를 극대화하는 방향으로 적극적으로 금리자유화를 추진하는 것이 바람직하다.

The purpose of this paper is to investigate the relationship between foreign ownership and firm value. Based on the sample of 3,398 firm-year observations in the period of 2000 to 2007, we find evidence that foreign ownership is positively associated with firm value measured by the market-to-book ratio. In addition, we employ simultaneous equation system where both foreign ownership and firm value are treated as endogenous variables. Simultaneous regression models indicate that the foreign ownership affects firm value, but not vice versa. The positive effects of foreign ownership on firm value result from monitoring and disciplining roles played by foreign investors. Many Korean firms have been run by an owner-manager while monitoring provided by institutional equity holders has been limited. Therefore, Korean firms are expected to suffer from more severe agency costs caused by the conflicts of interest between owner-managers and outside investors. Our empirical results support the notion that foreign investors play an important role in enhancing corporate transparency and improving corporate governance.

Platform finance is emerging as an alternative finance for SMEs by suggesting a new funding source based on a new technology named FinTech. The essence of this business is the adapting ICT challenges to the financial industry that can adequately reflect risk assessment using Big Data and effectively meet individual risk-return preference. Thus, this is evolving as an alternative to existing finance in the form of P2P loans for Micro Enterprises and supply-chain finance for SMEs that need more working capital. Platform finance in Korea, however, is still at an infant stage and requires policy support. This can be summarized as follows: "Participation of institutional investors and the public sector," meaning that public investors provide seed money for the private investors to crowd in for platform finance. "Negative system in financial regulations," with current regulations to be deferred for new projects, such as Sandbox in the UK. In addition, "Environment for generous use of data," allowing discretionary data sharing for new products," and "Spreading alternative investments," fostering platform finance products as alternative investments in the low interest-rate era.

This paper uses the Efficient Method of Moments(EMM) of Gallant and Tauchen to estimate continuous-time stochastic volatility diffusion model for the Korean Composite Stock Price Index, sampled daily over $1995\sim2002$. The estimates display non-normality of stock index return, leptokurtic distribution, and stochastic volatility. Funker, this study suggests that two factor stochastic volatility model will be more desirable than one factor stochastic volatility model to estimate daily Korean stock return and also suggests that the stochastic volatility diffusions should allow for Poisson jumps of time-varying intensity.

본(本) 연구(硏究)는 한국증권시장(韓國證券市場)에서 무위험자산이 존재하지 않을 경우에 대용시장(代用市場)포트폴리오의 효율성(效率性) 검증(檢證)을 다변량(多變量)의 검증방법(檢證方法)에 의해 실시하고자 하였다. 검증을 위하여는 첫째로 제로베타수익률을 구하고자 하였으며 이는 Kandel(1984)과 Shanken(1985)의 연구에 기초하여 추정하는 방법을 제시하였다. 둘째로 Jobson-Korkie(1982,1989), Handel(1984,1986)과 Shanken(1985,1986)의 논문(論文)에 의거 대용시장포트폴리오의 효율성을 검증하는 과정을 유도하고 이의 검증(檢證) 통계량(統計量)을 유도하였다. 효율성 검증에 사용된 대용시장포트폴리오들은 한국종합주가지수(韓國綜合株價指數), 한경(韓經)다우지수(指數)와 2개의 동일가중지수(同一加重指數)이었다. 실증적 연구결과, 전기간(全期間)의 경우에 한국종합주가지수(韓國綜合株價指數)와 한경(韓經)다우지수(指數)의 평균수익률은 GMVP의 수익률보다 낮을 뿐만아니라 평균-분산(平均-分散)프론티어의 외부(外部)에 위치하여 이 대용시장지수(代用市場指數)들이 효율적(效率的)프론터어상에 있는가에 대한 검증(檢證)은 불가능하였다. 그리고 하위기간별분석(下位期間別分析)에서도 이 대용시장지수(代用市場指數)(후반기(後半期)의 한경(韓經)다우지수(指數) 제외)들은 평균-분산프론티어의 내부(內部)에 있어 효율성 검증은 가능하였다. 그러나 이는 대용시장지수(代用市場指數)가 효율적 프론티어상에 있는가에 대한 효율성 검증이 아니라 단순히 평균-분산프론티어상에 있는가에 대한 검증에 불과하였으며 이러한 검증 결과는 효율적(效率的)인 것으로 나타났다. 한편 한국증권거래소(韓國證券去來所)에 상장(上場)된 전 종목(種目)을 대상으로한 동일가중지수(同一加重指數)와 본 연구의 기준시점인 1980년도에 한국증권거래소에 상장된 종목을 대상으로 구성한 동일가중지수(同一加重指數)는 이들의 평균수익(平均收益)이 GMVP의 수익률보다 높을 뿐만 아니라 대용시장지수(代用市場指數)가 효율적(效率的) 프론티어 상에 있는가에 대한 효율성 검증에서 모두효율적(效率的)인 것으로 나타났다. 이러한 사실은 한국종합주가지수(韓國綜合株價指數)를 근거로 기관투자자들이 투자수익율(投資收益率)의 관점에서 포트폴리오를 구성하거나 CAPM의 실증적(實證的) 연구시에 대용시장지수(代用市場指數)로 사용하는 것은 문제점이 있는 것으로 판단되며 따라서 동일가중지수(同一加重指數)를 선택함이 바람직할 것으로 사료된다.

In Korea, middle and small-sized company takes up an absolute majority of all businesses, and most of them are founded as a limited company. Yet, it is a type of business that fits a company of certain size, and its establishment process is complicated due to various reasons such as investor protection. It is also required to have strict organization structure based on the principle of separation of ownership and management. Accordingly, as the principles may undermine entrepreneur's will to start business, there has been dramatic change in legal system on business establishment and management since 2010.

Project Financing (PF) is a financing method, executed based upon the projected profitability from a project itself instead of relying on the credit rating of project sponsors or any type of collateral. However, most financial institutions of Korea lacks the long term profitability assessment capability, and they prefer to acquire credit reinforcement from the construction companies in the form of the guarantor or debt argument commitments. As a result, PF contingent liabilities as an indirect debt, are burdened to the construction companies. Even though the PF contingent liabilities are not supposed to be part of the financial statements, they became a mandatory disclosure items since 2009. In this study, PF contingent liabilities were studied to indicate how they were correlated with construction firms' financial ratios. Construction firms were grouped by their credit rating and each group was compared in order to analyze PF contingent liabilities' impact on the financial condition of the company in terms of liquidity, liability, and stability.

During the past decade, it seems apparent that Bitcoin has been the best performing asset class. Even without a centralized authority that takes control over, Bitcoin, which started off with basically no value at all, reached around 65000 dollars in 2021, showing a movement that will definitely go down in history. Thus, even those who were skeptical of Bitcoin's intangible nature are stacking bitcoin as a huge part of their portfolios. Bitcoin's exponential growth in value also caught the attention of traditional banking and investment firms. Along with the spotlight Bitcoin is getting from the investment world, research using macro-economic variables and investor sentiment to explain Bitcoin's price movement has shown progress. However, previous studies do not make use of On-Chain Data, which are data processed using transaction data in Bitcoin's blockchain network. Therefore, in this paper, we will be utilizing LSTM, a method widely used for time-series data prediction, with On-Chain Data to predict the price of Bitcoin.
