Purpose - This paper examines the effect of related party transactions on crash firm-specific stock price crash risk. Ownership of a typical Korean conglomerate is concentrated in a single family. In those entities, management and board positions are often filled by family members. Therefore, a dominant shareholder can benefit from related party transactions. In Korea, firms have to report related party transactions in financial statement footnotes. However, those are not disclosed in detail. The more related party transactions are the greater information risk. Thus, companies with related party transactions are likely to experience stock price crashes. Research design, data, and methodology - 2,598 firm-year observations are used for the main analysis. Those samples are from TS2000 database from 2009 to 2013, and the database covers KOSPI-listed firms in Korea. The proxy for related party transactions (RTP) is calculated by dividing total transactions to the related-party by total sales. A dummy variable is used as a dependent variable (CRASH) in the regression model. Logistic regression is used to explain the relationship between related party transactions and crash risk. Then, the sample was separated into two groups; tunneling firms and propping firms. The relation between related party transactions and crash risk variances with features of the transaction were investigated. Results - Using a sample of KOSPI-listed firms in TS2000 database for the period of 2009-2013, I find that stock price crash risk increases as the trade volume of related-party transactions increases. Specifically, I find that the coefficient of RPT is significantly positive, supporting the prediction. In addition, this relationship is strong and robust in tunneling firms. Conclusions - The results report that firms with related party transactions are more likely to experience stock price crashes. The results mean that related party transactions increase the possibility of future stock price crashes by enlarging information asymmetry between controlling shareholders and minority shareholders. In case of tunneling, it could be seen that related party transactions are positively associated with stock crash risk. The result implies that the characteristic of the transaction influences crash risk. This study is related to a literature that investigates the effect of related party transactions on the stock market.

This study investigates the relationship between family ownership and the stock price crash risk. It believes that this relationship would never be in direct connection. The authors design and then find that family ownership is predisposed, in the first place, to the related party transaction, then the related party transaction causes the future stock price crash. This study infers that employing the power of family ownership creates the Type I agency problem, although this is not relevant for the Type II problem. From the perspective of the hoarding theory, family ownerships produce opaque accounts by blurring financial information. The blurred information is probably hidden in the related party transactions. This study, therefore, splits these transactions into accounts receivable, other accounts receivable and other receivables. Finally, this research concludes that the family ownership affects related party transactions. These then are used as an instrument to influence the leaded related party transaction. The latest, leaded related party transactions influence the future stock price crash. This study infers that related party transactions are abusive practices, especially on the types of receivables. It implies corporate governance's revitalisation.

Purpose - This study investigates the effects of earnings management, related party transactions between chaebol affiliates on earnings management and ESG score on their profitability using return on assets (ROA). Design/Methodology/Approach - We use data including ESG (Environmental, Social, and Corporate Governance) score of the Korea Corporate Governance Service(KCGS), and financial data of 10,145 firm-year observations from the Total Solution 2000 (TS 2000) and Korea Companies-Information Service (KOKOInfo), and apply the finite lagged models to investigate the long-term effects of related party transactions between chaebol affiliates of earnings management on ESG scores and corporate performance. Furthermore, to take into consideration the simultaneous mutual effects on each other of main variables, we introduce finite distributed lags of five years. Findings - First, ESG-rated firms have a higher total asset return than non-ESG-rated firms. Second, chaebol firms have a higher profitability than non-chaebol firms. Third, profit management of related party transactions between affiliates within a chaebol has a positive effect on the short-term profitability and a negative effect on the long-term profitability. Fourth, chaebol ESG firms have a lower impact on profitability due to rating up (down) than non-chaebol ESG firms. Research Implications or Originality - Based on the above results, it can be concluded that firms used related party transactions for earnings management, the effects of related party transactions change over time, and chaebol firms manipulate earnings through related party transactions and ESG scores.

This study analyzed the effect of related party transactions on the corporate value of Korean firms using panel data regression analysis. We tested the efficient transaction hypothesis and conflict of interests hypothesis which concern related party transactions. Five types of related party transactions were considered, including long term supply contracts, assets and business transfers, affiliate loans, equity investment, and credit offerings. If related party transactions were conducted for the purpose of enhancing corporate efficiency, results would have a positive effect on firm value. If related party transactions were conducted for the purpose of private profits of the controlling shareholders, the results would show a negative effect on firm value. Results were as follows. Firstly, it is confirmed that affiliate loans, equity investment, and credit offerings had negative effects on firm value. This implies that these types of related party transactions used by controlling shareholders for the purpose of their private profit, which supports the conflict of interests hypothesis. Secondly, it was found that long term supply contracts and assets and business transfers had no effect on firm value.

Over the years, more password-based authentication key agreement schemes using chaotic maps were susceptible to attack by off-line password guess attack. This work approaches this problem by a new method--new theorem of chaotic maps: $T_{a+b}(X)+T_{a-b}(X)=2T_a(X)T_b(X)$,(a>b). In fact, this method can be used to design two-party, three-party, even in N-party intelligently. For the sake of brevity and readability, only a two-party instance: a novel Two-party Password-Authenticated Key Agreement Protocol is proposed for resisting password guess attack in this work. Compared with the related literatures recently, our proposed scheme can be not only own high efficiency and unique functionality, but is also robust to various attacks and achieves perfect forward secrecy. For capturing improved ratio of security and efficiency intuitively, the paper firstly proposes a new parameter called security/efficiency ratio(S/E Ratio). The higher the value of the S/E Ratio, the better it is. Finally, we give the security proof and the efficiency analysis of our proposed scheme.

Standard contsacts are drafted by one side only and therefore naturally favour that party. The other party must either adhere to those terms or abandon the transaction entirely. Accordingly the terms in these contracts tend to by quite harsh, especially so in consumer transactions. The objectives of this study are to examine the degree of consumer knowledge practical use, experience of consumer problems on service contract terms and to investigate the factors which influence on the degree of experience of consumer problems related the contract terms. The data used in this empirical study included 685 consumers experienced transactions with the terms in the last two years in Seoul. Statistics used for data analysis ere Reliability, Frequencies, Means, Standard Deviation and Multiple Regression Analysis. The conclusions can be summarized as follows. 1) Actually, consumers experienced many problems related the service-contract terms, despite regulation of unfair contract terms. 2) The level of education and purchasing experience variables have affected positively to the level of consumer problem experiences related the contract terms. 3) The effect of trend and characteristics of contract terms are variables with the type of contract terms. Therefore the regulation of the contract terms have to by differently enforced according to the type of contract terms.

The purpose of this study is to examine the protection of third parties of the transactions made by the representative director without resolution adopted by the board of directors. The legal effect of a transaction conducted by a representative director without board resolution in violation of internal restriction or statutory restriction is at issue. The Supreme Court of Korea('SCK') made a new ruling that revised the prior case law(Supreme Court en banc Decision 2015Da45451, Feb. 18, 2021). The SCK in the subject case proclaimed a legal doctrine that 'a third party acting in good faith' shall be protected according to Article 389(3) and 209(2) of the Korean Commercial Act, except that 'a third party with gross negligence' is considered as 'a person acting in bad faith' and thus is excluded from protection. The subject case law can be evaluated as broadening the scope of protection of the third party. In addition, the subject case is meaningful in that it is balance with the related SCK ruling, which considered a third party with gross negligence as a person acting in bad faith while protecting a third party with ordinary negligence in the case of transactions involving apparent representative directors, etc.

If the existence and effect of the arbitration agreement becomes an issue in international business transactions, it is the key point how we shall determine the applicable law by national rules for the conflict of laws, or by other methods. The argument in determination of the applicable law to the existence and effect of the arbitration agreement is related to regal nature of the arbitration agreement. As there are foreign factors in international arbitration, therefore we must consider such an aspect. Besides, we have to examine whether the general theory of contract is universally applicable to the arbitration agreement. Currently, it is the general trend that the party's autonomy principle is applicable in determining the applicable law for the arbitration agreement. However, it is a difficult problem to recognize the applicable law chosen by the parties, whether it is based on any regal standard(for example New York Convention or the private international law or the essential quality of the arbitration agreement). In the light of the actual transactions, when the parties don't make a choice of the applicable law expressly, it will finally come down to presuming the party's implied intent. Nevertheless, finding the implied intent is a difficult problem. Some argue that we shall presume the choice of applicable law by an objective standard such as a place of arbitration, to prevent too much expansion of the scope of the recognition. But we need to review that this interpretation harmonizes with the principle of party autonomy. Especially, if we desire to detect the vital point where it is most closely linked to the arbitration agreement, we have to inquire how we will decide such a relation by means of any standard. However, as the existing Arbitration Act doesn't offer the solution to these issues, therefore we have to settle these problems through the development of adjudications and theories.

This study relates to the effect from enforcement of regulations in 2014 against controlling shareholder expropriation in Korean corporations. The relationship change between related party transactions (RPTs) and the corporate values of listed Korean corporations is analyzed for the five-year period before and after enforcement of the regulations (2009-2013 and 2014-2018). Three types of RPTs regarding long-term supply contracts, loans, and credit were adopted for analysis. Following are the results of a regression analysis with panel data that consist of 6,534 firm-year observations. First shown is that the enforcement of regulations affects the relationship between RPTs and corporate value. Specifically, for all corporations, the result implies that the purpose of expropriation is weakened, and the efficiency and transparency of transactions in corporations are enhanced due to enforcement of the regulations. Secondly, the extent to which the regulations exert influence on designated and non-designated corporations differs. Regulation enforcement seems to be more influential on non-designated corporations than on designated ones for the efficiency and transparency of transactions in the long-term contract type of RPT.

Data sharing is an essential process for collaborative works particularly in the banking, finance and healthcare industries. These industries require many collaborative works with their internal and external parties such as branches, clients, and service providers. When data are shared among collaborators, security and privacy concerns becoming crucial issues and cannot be avoided. Privacy is an important issue that is frequently discussed during the development of collaborative systems. It is closely related with the security issues because each of them can affect the other. The tradeoff between privacy and security is an interesting topic that we are going to address in this paper. In view of the practical problems in the existing approaches, we propose a collaborative framework which can be used to facilitate concurrent operations, single point failure problem, and overcome constraints for two-party computation. Two secure computation protocols will be discussed to demonstrate our collaborative framework.
