수출기업들의 수출채권을 금융기관이 상환청구불능조건으로 매입하여 수출기업들의 신용위험을 해소시켜주는 금융기법이 포페이팅이다. 포페이팅통일규칙이 2013년 1월부터 발효하게 되어 수출기업들의 관심증대와 외국환은행들의 포페이팅관련 상품개발이 확대해 가고 있는 추세이며, 포페이팅 취급에 따른 위험관리에 관심이 제고되고 있다. 따라서 본고에서는 국내 외국환은행과 외국계은행 간의 포페이팅 위험관리 실태를 각 은행의 약정서를 통해 비교해보고 국제상업회의소의 표준 포페이팅계약서와도 비교해보고자 한다. 본 연구결과 국내 외국환은행은 담보위험과 유보사유인 소구가능 사유가 은행간 차이가 상당히 있음을 발견하였고 수출기업과 외국환은행의 위험관리차원에서 통일의 필요성이 제기된다.

In this paper, we propose the new time-varying coefficient GARCH-in-Mean model. The benefit of our model is to allow the risk-return parameter in the mean equation to vary over time. At the end of 2019 to the beginning of 2020, the world witnessed two shocking events: COVID-19 pandemic and 2020 oil price war. So, we decide to use the daily data from December 2, 2019 to May 29, 2020, which cover these two major events. The purpose of this study is to find the dynamic movement between risk and return in four major oil markets: Brent, West Texas Intermediate, Dubai, and Singapore Exchange, during COVID-19 pandemic and 2020 oil price war. For the European oil market, our model found a significant and positive risk-return relationship in Brent during March 26-April 21, 2020. For the North America oil market, our model found a significant positive risk return relationship in West Texas Intermediate (WTI) during March 12-May 8, 2020. For the Middle East oil market, we found a significant and positive risk-return relationship in Dubai during March 12-April 14, 2020. Lastly, for the South East Asia oil market, we found a significant positive risk return relationship in Singapore Exchange (SGX) from March 9-May 29, 2020.

본 연구의 목적은 캄보디아와 베트남의 국가위험도와 영향요인들을 비교 분석하는 것이다. OECD와 한국수출입은행 모두 베트남보다는 캄보디아의 국가위험도를 더 높게 평가하고 있다. 국가위험도 분류에 따른 각각의 평가요소들에 대해 모수검정을 실시한 결과, 정치 사회적 위험 지표인 부패지수, 경제적 위험 중 국내경제 지표인 경제성장률, 경제적 위험 지표 중 대외거래 지표들, 경제적 위험 중 외채 관련 지표가 두 국가 간의 국가위험도 차이에 통계적으로 유의한 영향을 미쳤다. 국가위험도 분류에 따른 평가요소별 모수검정 결과를 토대로 판별요인 분석을 통해 두 국가 간의 국가위험도를 가장 잘 나타내는 요인들을 추가로 추정한 결과, 정치 사회적 위험 지표인 부패지수, 경제적 위험 중 국내경제 지표인 경제성장률, 경제적 위험 중 외채 관련 지표인 외환보유액/월평균수입이 캄보디아와 베트남 간의 국가위험도 차이를 잘 대변하는 것으로 나타났다. 결론적으로 캄보디아가 국가위험도를 베트남 수준으로 낮추기 위해서는 무엇보다도 부패척결, 수출증대 등 대외거래 확대가 필요하다고 할 것이다. 베트남 또한 지속적인 경제성장 달성과 외환보유고 증대에 주력할 필요가 있을 것이다.

This paper aims to investigate the time-varying systematic risk of the stocks of Korean logistics firms. For this purpose, the period from January 1991 to October 2016 was examined with respect to 21 logistics companies that are listed on the Korea Exchange. The systematic risk of the logistics stocks is measured in terms of the Capital Asset Pricing Model (CAPM) beta for which the sensitivity of a stock is compared to the return changes of the whole market. Overall, the betas of the stocks of the Korean logistics companies are significantly lower than those of the market unity; however, it was revealed that the logistics betas are not constant, but are actually time-varying according to different economic regimes, which is consistent with the previous empirical findings. This finding is robust across different measurements of the logistics betas. In addition, the impact of macroeconomic factors on the logistics betas was examined. The present study shows that the logistics betas are positively associated with foreign exchange-rate changes.

Purpose: This research aims to investigate the impact of corporate integrity on stock price crash risk. Research design, data, and methodology: Taking 1419 firms listed in Shenzhen Stock Exchange in China as a sample, this paper empirically analyzed the relationship between corporate integrity and stock price crash risk. The main integrity data was hand-collected from Shenzhen Stock Exchange Website. Other financial data was collected from CSMAR Database. Results: Findings show that corporate integrity can significantly decrease stock price crash risk. After changing the selection of samples, model estimation methods and the proxy variable of stock price crash risk, the conclusion is still valid. Further research shows that the relationship between corporate integrity and stock price crash risk is only found in firms with weak internal control and firms in poor legal system areas. Conclusions: Results of the study suggest that corporate integrity has a significant influence on behaviors of managers. Business ethics reduces the likelihood of managers to overstate financial performance and hide bad news, which leads to the low likelihood of future stock price crashes. Meanwhile, corporate integrity can supplement internal control and legal system in decreasing stock price crash risks.

The purpose of this study is to compare the level of risk and return of Islamic stocks in the Jakarta Islamic Index (JII) with conventional stocks on the IDX30 in the period from January 2017 to July 2019. The Sharpe ratio method is used to calculate risk and stock returns. The performance of the stock portfolio is measured by comparing the risk premium portfolio with the portfolio risk that is expressed as a standard deviation of the total risk. This study uses secondary data collected by the Indonesia Stock Exchange (IDX), which provides the names of stock issuers included in the JII and IDX30 indices along with their montly closing price. The results of the descriptive analysis show that the JII Sharpe ratio index from January 2017 to July 2019 is from the minimum range of -0.28820 to a maximum range of 0.05622, while the IDX30 Sharpe ratio index from January 2017 to July 2019 is from the minimum range of -0.09290 to the maximum range of 0.17436. The results of inferential analysis using a different test show that there is a significant difference between the Sharpe ratio JII and IDX30 in measuring the performance of the stock portfolio.

The research objective of the paper is to clarify the factors influencing system risks of listed companies in Vietnam, with a focus on clarifying the relationship and quantifying the impacts of ownership structure on systemic risk of listed companies. The data used in this study included financial statements and stock price data of listed companies on the Ho Chi Minh City Stock Exchange and Hanoi Stock Exchange of Vietnam stock market in the period from 2010 to 2017. The paper used the method of estimation in establising the regression models to choose among three models: Random Effect Model, Fixed Effect Model or Pooled OLS for regression using Stata statistical software. The research results showed that state ownership and ownership by foreign investors were positively related to systemic risk, while ownership by domestic investors had a reverse relationship with systemic risk of listed companies in Vietnam. In addition, as a control variable, both company size and profitability had an effect on the systemic risk of listed companies in the research sample. Based on the research results, the authors interpreted some of the implications in order to minimize systemic risks in the operation of listed companies in Vietnam.

This study aims to investigate the influence of internal factors on the bankruptcy risk of an enterprise through a sample of 439 companies listed on the Vietnamese stock exchange. The research collected secondary data from annual audited financial statements from 2008 to 2019 of listing companies. Using two different regression models with two dependent variables, six independent and control variables, we discovered that three of the model's six factors, namely return on total assets, current payment rate, and financial leverage, influence the risk of bankruptcy and account for 86.78% of the variations in firm bankruptcy risk. Financial leverage has the opposite effect on the Z-score index, increasing the risk of bankruptcy of listed firms. Return on total assets and current ratio have a positive impact on the Z-score index, reducing the risk of bankruptcy of listed companies. The findings also revealed that there is no evidence that the size of a corporation, its fixed asset investment ratio, or the size of an auditing firm have an impact on the Z-score index. These findings provide crucial evidence for business owners and managers, as well as shareholders making future capital investment decisions. Our findings can be applied to other businesses in Vietnam and similar jurisdictions.
