  • The growing trend of cyber risk has put forward the importance of cyber risk management. Cyber risk is defined as an accidental or intentional risk related to information and technology assets. Although cyber risk is a subset of operational risk, it is reported to be handled differently from operational risk due to its different features of the loss distribution. In this study, we aim to detect the characteristics of cyber loss and find a suitable model by measuring value at risk (VaR). We use the loss distribution approach (LDA) and the time series model to describe cyber losses of financial and non-financial business sectors, provided in SAS® OpRisk Global Data. Peaks over threshold (POT) method is also incorporated to improve the risk measurement. For the financial sector, the LDA and GARCH model with POT perform better than those without POT, respectively. The same result is obtained for the non-financial sector, although the differences are not significant. We also build a two-dimensional model reflecting the dependence structure between financial and non-financial sectors through a bivariate copula and check the model adequacy through VaR.

  • This study examines the impact of bank restructuring on the financial performance of commercial banks in Vietnam. The data for this study was obtained from the audited financial statements of 30 Vietnamese commercial banks from 2007 to 2019. Multiple regression analysis was used for investigation. Financial performance, as evaluated by ROAA, ROEA, and NIM, is the dependent variable. Financial restructuring, ownership restructuring, and operational restructuring are the independent variables. Pooled least squares (Pooled OLS), fixed effects model (FEM), random effects model (REM), and system generalized moment regression model (System GMM) are the estimate methods used to increase the accuracy of the regression coefficient. The research results show that the variables of financial restructuring activities such as government intervention and the ratio of equity to total assets; variables of ownership restructuring such as capital adequacy ratio, privatization of state-owned commercial banks, mergers, and acquisitions; variables of operational restructuring such as employees, branches, the cost to total assets; GDP variables and the second restructuring period have a positive impact on financial performance. Variables such as debt-to-capital ratio, bad debt ratio, state ownership ratio, expense-income ratio, and inflation have a negative effect on financial performance.

  • This study aimed to identify the key factors that affect the financial market performance (Price-Earnings Model) through a sample of 35 public shareholding industrial companies on the Amman Stock Exchange for the period 2010-2019, using statistical models and methods, such as the Simple Linear Regression Model, Correlation Coefficient, and dispersion board. The study results showed the nonexistence of a statistically significant effect between the intellectual capital and market value added (MVA) and market performance. Results also showed a statistically significant positive effect between financial leverage (FL) and the market performance, where the interpreted variation reached 64%. It showed from the analysis results that the relationship between (MVA) and market performance (P/E) agrees with the study hypotheses, while the result related to (FL) disagrees with the study hypotheses. The study recommends that public shareholding industrial companies should focus more on intellectual capital and show its value in the annual financial statements and reports, and those companies that have high profitability and the chance to hold gains and profits should rely less on debt and more on retained earnings, due to the high risk of debt and in line with the present unstable circumstances in Jordan, especially in light of the global Covid-19 crisis.

  • The study aims to assess the impact of factors on the access to financial services by Vietnamese farmers. The number of respondents in this study is 402 household heads participating in six diverse agricultural value chains in Vietnam. The explanatory variables of the Multinomial Logit model estimates variables at the individual characteristics while the Mixed Logit model can combine the two types of variables together to estimate the effects simultaneously. On the other hand, the Ordinal Logit model is used to evaluate the determinants of the increase in the quantity of financial services used by individuals. The estimation results show that male-headed households have more access to financial services than females. Younger farmers are more likely to use formal financial services than the elderly. Financial literacy, land ownership, and shocks in agricultural production all have a positive impact on the probability of dealing with banks. In addition, the degree of linkage and credibility of the value chain have a significant positive impact on the accessibility of financial services to farmers. The findings of this study suggest that limiting gender inequality, focusing on youth marketing and developing agricultural value chains will have a positive impact on farmers' access to financial services.

  • The purpose of this study was to test a causal model of subjective financial well-being. The data of this research was obtained from 660wives who lived in Seoul, 1996. Major findings of this study were at follows: 1. Both employed and unemployed wives, younger managers were more likely to have a higher cohesion and adaptability between spouses. For the unemployed wives, locus of control over managers’financial situation and perception of gap between standard and level of living were significant predictors of the personal subsystem. 2. In both groups, financial planning was positively influenced by amount of saving. But amount of saving was not significant predictor of financial implementing. Financial implementing was positively influenced by locus of control, in the unemployed wives. For the employed wives, predictors of financial implementing were family income and marriage duration. 3. For the employed wives, the effect of personal and managerial subsystem on subjective financial well-being was greater than unemployed wives. 4. It was found that personal and managerial subsystems had effect on subjective financial well-being. Thus, the path model designed in this research was found to be proven for employed and unemployed wives.

  • This study aims to analyze older adults's intention to use digital financial services. To verify the purpose, the '2022 Korean Senior Technology Acceptance Panel Survey' data were used. And a shortened Senior Technology Acceptance Model(STAM) reflecting the characteristics of older adults was applied. The results of Structural Equation Model analysis are as follows. First, the lower gerontechnology anxiety, the higher control beliefs reflecting perceived ease of use, self-efficacy and facilitating conditions and the intention to use digital financial services. Second, the health factor had a positive effect on the control beliefs. Third, the higher the control beliefs, the higher the attitudinal beliefs reflecting perceived usefulness and attitude and the intention to use digital financial services. Lastly, the higher attitudinal beliefs, the higher the intention to use digital financial services. The results suggest the need for interventions that can relieve gerontechnology anxiety and strengthen positive perceptions about control beliefs and attitudinal beliefs in order to increase older adults's intention to use digital financial services.

  • 우리나라의 금융ADR제도는 금융감독당국인 금융감독원 및 그 안에 설치되는 금융분쟁조정위원회가 제도운영의 주체가 되는 이른바 "금융분쟁조정제도"로 대표된다고 할 수 있고, 이를 흔히 "행정형 금융ADR제도"라고 평가하고 있다. 이 제도는 금융위원회설치법(1997)에 의해 1999년경에 도입되어 10여년에 걸친 제도운영의 성과를 축적하여 현재에 이르고 있다. 그런데 정작 우리나라에서 금융ADR제도가 주목받기 시작한 것은 대체로 2008년의 이른바 금융위기 이후에 금융소비자보호가 강조되기 시작하면서이다. 금융거래를 통하여 피해를 입은 금융소비자를 보호하기 위한 제도적 방안의 하나로 "소송외적 분쟁해결제도(이른바 ADR)"에 대한 관심이 높아졌기 때문이다. 그나마 우리나라 금융ADR제도에 관한 논의는 주로 감독체제 개편과 관련하여 금융ADR기관의 운영주체를 누구로 할 것인가에 집중되었다는 점에 특이성이 있고, 우리 금융ADR제도의 특징을 객관적인 입장에서 면밀하게 분석한 위에 제도개선의 방향성을 제시하는 논의는 충분하게 이루어졌다고 할 수 없다. 본고는 이와 같은 점들을 문제의식으로 하여 우리나라의 금융ADR제도의 특징을 분석하여 하나의 제도모델로 구체화하고, 이를 통하여 제도의 문제점을 분명히 하고 그 개선방향을 제시하고자 하였다. 우리나라 금융ADR제도는 "행정형 통합형 합의형+집행력 부여형(준사법형) IDR비전치형(ADR기관내 합의권고형)"의 특징을 갖는 제도모델로 평가할 수 있다. 그러나 준사법형 효력모델을 채택하면서도 제도의 실효성확보를 위한 제도적 기반을 갖추지 못하고 있고, 통합형 ADR기관의 제도운영의 부담이 크다는 두 가지 문제점을 극복하여야 하는 과제를 동시에 안고 있다. 그러한 관점에서 본고는 현행 제도의 실효성 확보와 업계자율형 ADR제도(특히 IDR전치형 제도)의 확충을 위한 개선방안을 제시하였다. 특히 제도의 실효성확보 방안으로서 조정안에 편면적 구속력을 부여하지 않고도 조정성립율을 높일 수 있는 방안이 제도개선으로서는 최선책이라는 전제 하에 내부의 인원확충을 도모하고 조정절차 및 효력을 차등화하는 방안, 금융기관이 조정절차 중에 소송으로 도피하는 문제점을 해결하기 위하여 피신청인인 금융기관은 합의권고 또는 조정안을 제시받기 전에는 소를 제기하지 못하도록 규제하는 방안, 소송과의 연계제도로서 소송절차의 중지제도 외에 시효중단효를 부여하는 방안을 각각 제시하였다.

  • Joint financial network of Korea Financial Telecommunications and Clearings Institute, which is an essential facility with a natural monopoly, maintained its closedness as monopoly/public utility model, but it has evolved in the form of open banking in order to obtain domestic fintech competitiveness in the rapidly changing digital financial ecosystem such as the acceleration of Big Blur. In accordance with digital transformation strategy of financial institutions, various ICT companies are actively participating in the financial industries, which has been exclusive to banks, through the link technology called Open API. For this reason, there has been a significant change in the financial service supply chain in which ICT companies participate as users. The level of security in the financial service supply chain is determined based on the weakest part of the individual components according to the law of minimum. In addition, there is a perceived risk of personal information and financial information leakage among the main factors that affect users' intention to accept services, and appropriate protective measures against perceived security risks can be a catalyst, which increases the acceptance of open banking. Therefore, this is a study on factors affecting the introduction of open banking to achieve financial innovation by developing an open banking security control model for financial institutions, as a protective measures to user organizations, from the perspectives of cyber financial security and customer information protection, respectively, and surveying financial security experts. It is expected, from this study, that effective information protection measures will be derived to protect the rights and interests of financial customers and will help promote open banking.
