An equity crowdfunding system of Korea has been introduced since January 25, 2016. The crowdfunding has contributed to remove the funding gap for startups in Korea. In the three years since the introduction of the system, the amount issued has been growing annually 31 percent. In 2018, the general investors who participated in equity crowdfunding, account for 93.8% of the total market size. General investors are a large part of equity crowdfunding. Investors, however, are facing the information asymmetry problems. General investors rely heavily on the investment prospectus provided by startups to obtain the information they need to determine their investment decisions. Under these circumstances, startups have the incentive to provide information that is advantageous to them, and investors are likely to be adversely affected by the investment prospectus. In this study, we collected the novel crowdfunding prospectus dataset: a total of 459 investment prospectus and conducted a morphological analysis. The analysis showed that the more positive the word, the higher the success rate of investors' subscriptions. We also compared projects that were heavily invested by general investors with projects that were heavily invested by professional investors. Then, we were able to examine that the success rates of project subscription, which were heavily invested by general investors, were higher than the projects of professional investor type. It can be interpreted as a general investor driven crowdfunding market. Based on these results, we propose three policies. First, the supervisor should be strengthened to provide more detailed information on investment risk factors in the prospectus. Second, the crowdfunding intermediary should monitor information provided by startups. Third, an investor should be asked to add a question to the investment compliance test that allows the investor to recognize the problem in the manual.

The purpose of this study is to grasp the correlation between network and firm's performance by analyzing the perception and characteristics of network of business founder and investor from the perspective of the network. We selected a TIPS support program which is evaluated to be a best practice as a research target for empirical analysis. The empirical results using social network and statistical analysis, shows that the stronger the investor's network connectivity, the more likely it is that the investor's start - up succeeds in attracting subsequent investment. In addition, both the entrepreneurial team and the management think that the internal human network between the enterprise and the investor plays an important role in inducing investment or exploring the company, and recognizes that the value of the human network will have a significant influence on the enterprise value evaluation or investment decision.

South Korea has investment agreements such as FTAs, BITs with several countries. Up to now, no single case has been registered against the Korean government on breach of investment agreements, but it is likely that the number of such cases would increase. Therefore, an investor-state dispute settlement system, an arbitral procedure by which a foreign investor may seek compensation of damage against the host country, is gaining its importance. The provision of the ISDS has been one of the hottest issues in Korea while the Kor-US FTA was being signed. In this respect, with the growing number of regional agreements such as BITs and FTAs, a careful scrutiny on the ISDS is necessary for Korea. I have therefore studied theoretically subjects including the National Treatment(NT), the Most-Favored Nation(MFN), Fair and Equitable Treatment and Expropriation - those that have been the objects of protection on investors. And I have analyzed ICSID arbitral awards and provided implications. In the ICSID arbitral awards, the Fair and Equitable Treatment turned out to be the most recognized violation on investors by the host State in terms of investor protection. On the other hand, Indirect Expropriation - a matter of which public anxiety was shown led by civic groups - was not generally recognized in arbitral awards. This study is written for sake of governments, local autonomous entities and public enterprises that are in charge of FTAs and BITs.

Energy is an essential element in economic activity and people's lives, an important resource used by various industries, and the financialization of commodity markets has led to the growing importance of crude oil turning into the same asset as other assets. Accordingly, studies analyzing the correlation between energy prices and investor sentiment explain that investor sentiment affects oil prices through economic factors and speculation. In this study, we wanted to analyze whether the impact of the most representative changes in oil prices affects investor decision making, affecting investor sentiment, and applying wavelet consistency analysis to determine how energy prices relate to investor sentiment. Studies show that policies should be focused on policy and market changes because energy prices differ by time scale and investment sentiment should be more influential in the long term than in the short term.

The ICSID arbitral tribunal shall determine the suitability of investors in accordance with the Article 25 of the ICSID convention and the investment or investor's provisions under the BIT. The eligibility of investors has an important role in establishing jurisdiction under international investment disputes. Therefore, this study draws implications on issues related to investor qualification, focusing on ICSID arbitration. The investor's nationality shall be taken into consideration in determining whether the investor is eligible. The criteria for determining the nationality of a corporate investor include the place of incorporation, main business location, and substantial ownership or control. The criterion of the place of incorporation that is used in a number of BIT have the problem of protecting investors from third countries not involved in the BIT. So, in recent years it is stipulated that the actual economic activity or the main business location as well as the place of incorporation criteria. And this problem is complemented by the denial of benefit clause. When determining whether a local corporation is controlled by foreigner in the host state it considers the shareholding rate, voting rights, and the exercise of managerial rights. There is a tendency to recognize shareholder's right to petition. Thus the same damage should not cause problems such as duplicate repayment or double reimbursement between the shareholders and the company. Unexpected problems can arise if the scope of investments and investors is broadly specified in the BIT. Therefore, it is necessary to clarify the scope of investment to be protected.

In previous studies concerning turnover, they argue individual stock's turnover must be identical to market portfolio's turnover under one condition where 2 funds separation theorem holds. In this kind of world, all market participants hold and trade the same portfolio and this should be only market portfolio. If one's trading portfolio's shape is different from market portfolio's, this would mean he or she has an advantage over others in information and this kind of information would be private. In accordance with this theory, we develop a metric which measures how far one's trading portfolio from market's and name it as Stock Selection by Investor(SSI). We apply this measurement to the various types of investor groups classified as individual, institutional and foreign who participate in Korea stock market. To test the validity of measure, we regress price ratio on this measurement using SUR method. As a result, individual investor group shows large number in SSI, but the coefficient in regression is not significant and economically meaningless. In case of institutional investor group, the coefficient proves to be significantly negative. We can infer from this fact that their trading is somehow far from informed trading. Stock selection activity by foreign investor groups proves to be informed trading by showing significantly positive coefficient and the magnitude of coefficient is economically meaningful, especially in sell activity.
