The Modigliani-Miller Proposition II (MM2) is a cornerstone in the field of corporate finance, positing that in a frictionless environment with perfect capital markets, the cost of equity capital is linearly related to a firm's leverage. This paper critically re-evaluates this proposition, particularly examining the determination of the cost and value of equity. We find that under specific circum-stances, especially when the value of a tax shield is influenced by endogenous variables, the cost and value of equity may be ambiguous. This calls into question the universal applicability of MM2. Our research offers new perspectives on the theoretical underpinnings of financial management and underscores the significance of situational factors in the practical application of these theories.

The popularity of Islamic financial instruments among Muslims is not surprising. The Islamic capital market is where sharia-compliant financial assets are transacted. It works parallel to the conventional market and helps investors find sharia-compliant investment opportunities. At a time of collective confusion when the COVID-19 epidemic is contributing to unprecedented change, this paper is keen to understand how attractive conventional and Islamic stock markets have been to investors recently. Second, this paper takes advantage of the time-scale decomposition property of the wavelet to simultaneously capture risk exposure and distinguish the risks faced by short- and long-term investors. To this end, this research conducted a two-step investigation of the daily closing equity market price indices for three Islamic stock markets and their conventional counterparts. Given that different financial decisions occur with greater or less frequency, the paper examines the connectedness of stock markets operating at heterogeneous rates and identifies the timescales using wavelet-DCC-GARCH analysis to take account of both the time and the frequency domains of stock market connectedness. The paper findings highlight the strong evidence of contagion that can be seen in nearly all conventional stock markets in the COVID-19 pandemic; they reach a high level of dependency in such health crises. Furthermore, Islamic stock markets prove to be a rich ground for global diversification.

미 연준은 2015년부터 통화정책의 정상화를 진행하고 있으며, 이는 우리 경제에 상당한 영향을 미칠 수 있다. 본 연구는 '시변모수 벡터자기회귀' (Time-varying parameter vector auto regression, TVP-VAR) 모형을 바탕으로 미국 통화정책이 우리나라 금융시장과 자본유출입에 미치는 영향을 분석한다. 미국 통화정책의 변화는 신용스프레드, 페더럴펀드 금리(정책금리), 기간프리미엄 등 세 변수를 통해 파악하였다. 국내 변수로는 금융시장 지표(장기금리, 원/달러 환율, 신용스프레드)와 국제수지표 금융계정을 분석하였다. 미국 정책금리 충격은 2004~2006년 금리인상기에는 국내 금융시장에 불안을 야기 시키고 외국인 국내 투자와 내국인 해외투자의 동시 감소를 초래하였으나 2015년 이후에는 그 효과가 제한적인 것으로 드러났다. 미국 기간프리미엄의 영향력은 양적완화 (Quantitative Easing, QE) 정책 실시 이후 확대되었다. 미국 신용스프레드가 국내 금융시장과 자본유출입에 미친 충격은 글로벌 금융위기 이후 크게 확대된 것으로 나타났다. 미국 통화정책 정상화의 파급효과 예측을 위한 시뮬레이션을 실시한 결과 정책금리 인상 자체보다 이로 인해 금융시장이 불안해질 때 발생할 수 있는 신용스프레드의 상승이 국내 금융시장에 더 큰 부작용을 미치는 것으로 나타났다. 자금유출입 측면에서 미국 통화정책 정상화는 외국인 투자자금의 국외이탈 압력 증가로 이어지나, 내국인의 해외투자자금이 국내로 환수되면서 이를 상쇄한다.

This paper examines the investment efficiency of Korean venture capitals during 1987~2006 (20 years), focusing on their selection capability. Despite the Korean government's efforts, venture capital industry has evolved in a slow speed. Since the genesis of venture paradigm in Korea at 1997, venture capital industry as a macro unit has been fully discussed in Korean contexts. But venture capital's activities at micro level regarding each investment's outcome have not been examined. This study attempts to fill the voids of micro knowledge about each investment success rates by venture capitals. We analyzed venture investment records in 4,791 venture startups and their success rates. Their investment criteria were relevant to high potential industries and amount of tangible assets. But their criteria were not relevant to R&D intensity and financial growth of venture firms, which may indicate low level of maturity about Korean venture capital industry. We found that Korean venture capital's investment pattern may be originated from the low return of investment, so that efficiency of IPO markets is a prerequisite for the upgrade of venture capitals' efficiency. Some policy implications are discussed.

The necessity for a theoretical explanation of the negative association between capital structure and company performance is identified in this study. By focusing on accounting metrics of business performance, this study is the first to investigate the moderating effects of firm size between these variables using logical reasoning. Due to the possibility of endogeneity, this study applies a two-step system GMM approach with data from 285 non-financial enterprises from PSX over a 21-year period. For robustness, we employed pooled OLS, fixed effect, and two-step difference GMM. Our data show that leverage has a detrimental impact on business performance, with size acting as a moderator in the same direction. Our analysis empirically supports some studies while refuting others due to inconsistent results in the literature, but no study has theoretically justified their negative link. We believe that because larger companies have more and easier access to capital markets, they focus primarily on the amount of return, even if the investment is inefficient in terms of the rate of return, but small businesses do not. As a result of this thinking, firm managers' performance suffers as a result of leverage.

전 세계적으로 금융시장에서는 예측할 수 없는 대형 사건들이 지속적으로 일어나고 있으며, 특히 보험시장의 경우에는 대재해성(catastrophe)손실 등을 포함한 극단적 사건에 대한 예측이 날이 갈수록 어려워지고 있는바 극단적 위험관리에 대한 필요성이 증대되고 있다. 극단적 위험관리에 있어 분포의 꼬리영역만을 분리하여 그 정보를 최대로 이용하는 방법이 필요한데, 이러한 문제들을 해결하기 위해 극단치들의 움직임을 모형화 하는 소위 극단치 이론(Extreme Value Theory: EVT)을 이용하는 것이 요구된다. 극단치 이론은 현재 여러 분야에서 활용되고 있는데, 특히 금융시장에서는 극단적 변화가 미치는 영향을 분석하기 위해서 극단치 이론을 이용한 금융위험분석을 실시하고 있다. 본 연구에서는 위험관리에 있어서 극단치 이론의 중요성을 검토하고 보험사의 위험자본에 초점을 맞추어 손실 발생의 극단적 위험을 측정하고 이에 대비한 위험자본의 적정규모를 측정하여 보았다.

This paper tests the validity of pecking order theory by Myers(1977) and Myers and Majluf(1984) on Korean manufacturing firms listed in the KRX for the years of 1994 to 2003. We also want to see if there is any difference in financing behavior between chaebol affiliated firms and non-chaebol affiliated firms. We develop testable hypotheses from the idea that established relationship between bank and firm mitigates the problem of information asymmetry (Kang and Lim, 2001), and thus makes it easier for firms to raise funds through banks. The test result of the first stage shows that firms prefer cash reserves to debt financing, and prefer debt to equity. Chaebol affiliated firms are found to behave as if they already exploit internal capital markets. The second stage of the test carried out by dividing debt capital into bank loans and corporate bonds also shows a consistent pattern of financing behavior. Firms are testified to prefer cash to bank loans, bank loans to corporate bonds, and corporate bonds to equity. In this case chaebol affiliation seems to make firms behave as if they already establish internal capital markets. Further analysis shows that some, though not in every case, difference of ordering around the occasion of Korean financial crisis exists. It may be from the change of attitude of Korean firms to risk, or from weakened influence of internal capital market along with strengthened market power in the post-crisis period.

The power expansion planning is large and capital intensive capacity planning. In the past the expansion planning was established with the proper supply reliability in order to minimize social cost. However, the planning not used cost minimizing objective function in the power markets with many market participants. This paper proposed the power expansion planning process in the power markets. This system is composed of Regulator and GENCO's model. Regulator model used multi-criteria decision making rule. GENCO model is very complex problem. Thus, this system transacted the part by several scenario assuming GENCO model.

Measuring market fear is an important way of understanding fundamental economic phenomena related to financial crises. There have been several approaches to measure market fear or panic level in a financial market. Recently, herd behavior has gained its popularity as important economic phenomena explaining the fear in the financial market. In this paper, we investigate herd behavior in global stock markets with a focus on intercontinental comparison. While various risk measures are available for the detection of herd behavior in the market, we use the standardized herd behavior index in Dhaene et al. (Insurance: Mathematics and Economics, 50, 357-370, 2012b) and Lee and Ahn (Dependence Modeling, 5, 316-329, 2017) for the comparison of herd behaviors in global stock markets. A global stock market data from Morgan Stanley Capital International is used to study herd behavior especially during periods of financial crises.

This paper is to give some hints to solve the problems of the Korean The third Market suffering from the extreme shortage of the liquidity. To solve that problem, this paper mainly compare the liquidity indices of the Third Market with that of the Japanese third market, that is Mothers. The main liqudity indices of the Mothers shows better than that of the Korean Third Market redardless of the small numbers of the listed Firms. The main differences in the liquidity levels between two markets is to caused by the trading system. The Korean Third Market has been adapting the one-to-one trading system which most stock markets of the world gave up that system owing to the inefficiency. This paper shows the proper trading system for the Third Market is competitve trading system partialy combined with the market maker system beacause of the small firm characterristics.
