The small & micro business has the characteristics of both consumer credit risk and business credit risk. In predicting the bankruptcy for small-micro businesses, the problem is that in most cases, the financial data for evaluating business credit risks of small & micro businesses are not available. To alleviate such problem, we propose a bankruptcy prediction mechanism using the credit card sales information available, because most small businesses are member store of some credit card issuers, which is the main purpose of this study. In order to perform this study, we derive some variables and analyze the relationship between good and bad signs. We employ the new statistical learning technique, support vector machines (SVM) as a classifier. We use grid search technique to find out better parameter for SVM. The experimental result shows that credit card sales information could be a good substitute for the financial data for evaluating business credit risk in predicting the bankruptcy for small-micro businesses. In addition, we also find out that SVM performs best, when compared with other classifiers such as neural networks, CART, C5.0 multivariate discriminant analysis (MDA), and logistic regression.

Purpose - The letter of credit has been playing a major role to diminish overall risks which exist among concerned parties even though there are differences such as language, culture, law, and distance. This paper reviews essence of the letter of credit and its transaction principles, as well as overall practical questions based on the L/C transaction principle. It also investigates the risk of fraud occurrences in L/C transactions and the importance of fraud prevention and preventive measures in international L/C transactions, including the Fraud Rule, which is a major topic to consider in business transactions. Design/methodology - It is considered that an importing country's concerned parties and an exporting country's concerned parties face different situations. This study employs the existing framework to identify liability, responsibility, and obligation for all concerned parties across countries. Using a quite direct measurement of principles in the letter of credit, such as principle of independence, principle of abstraction, and principle of strictness and coincidence, we studied these differences. Findings - Our main findings can be summarized as follow. The paper enhances the efficiency of the L/C payment method to provide fraud generated from L/C transactions, presentation of a theoretical framework about fraud and fraud prevention, which international trading companies should acknowledge in a material way based on fraud risk resulting from taking advantage of L/C transaction principles. Originality/value - Existing studies focus on fraud accidents in L/C transactions by taking bad advantage of the characteristics of the letter of credit without suggesting risks of fraud. This paper attempts to evaluate and provide preventive measures as a solution for fraud and risky international business in a letter of credit transaction. This area of trade studies is underexplored, both empirically and theoretically, although the issue has long been important to Korean and world community foreign trade.

The e-commerce market faces significant credit risks due to the complexity of the industry and information asymmetries. Therefore, credit risk has started to stymie the growth of e-commerce. However, there is no reliable system for evaluating the creditworthiness of e-commerce companies. Therefore, this paper constructs a credit risk evaluation index system that comprehensively considers the online and offline behavior of online retail enterprises, including 15 indicators that reflect online credit risk and 15 indicators that reflect offline credit risk. This paper establishes an integration method based on a fuzzy integral support vector machine, which takes the factor analysis results of the credit risk evaluation index system of online retail enterprises as the input and the credit risk evaluation results of online retail enterprises as the output. The classification results of each sub-classifier and the importance of each sub-classifier decision to the final decision have been taken into account in this method. Select the sample data of 1500 online retail loan customers from a bank to test the model. The empirical results demonstrate that the proposed method outperforms a single SVM and traditional SVMs aggregation technique via majority voting in terms of classification accuracy, which provides a basis for banks to establish a reliable evaluation system.

We proposed a framework for computer-supported credit evaluation systems for the effective management of credit risks in Korean commercial banks. Especially for medium and small sized companies, credit evaluators used to depend much on past experience rather than formalized principles and rules. Therefore, we applied case-based reasoning. The credit grade of a company is roughly determined by searching for alreadygraded similar companies in terms of usually accepted evaluation items. And then the grade is refined and adjusted by considering additional information about exceptional facts or by reflecting other evaluation results from different methods or techniques. Booch's object-oriented analysis and design method, Visual Basic 5.0 and MS Access 97 are used for the development of this prototype system.

This study aims to develop a theoretical model in order to determine factors affecting consumer intention to use credit cards by combining Theory of perceived risk and Technology acceptance model. Despite of perspective of consequences in prior studies on related research fields, this study focuses on the sources of perceived risk, including transaction, payment and credit risks, which are proposed and measured in a preliminary research. A measurement model and a structural model with the presence of perceived risk in sources are tested in a formal research with data collected from 538 bank customers. An analysis results show that payment risk, usefulness, transaction risk, ease of use, and credit risk influence significantly Vietnamese consumers' intention to use credit cards in decreasing order of influence. These factors account for 64.6% of the variation in intended use. All three dimensions of perceived risk have a negative effect on the intention to use, with the total impact greater than the level of influence of the other two factors of usefulness and ease of use. These findings can be beneficial to banks in enacting policies to attract more consumers and to allocate resources for improving their credit card business.

In this paper, we study the recent changes in the credit risk interconnectedness in Korea. Using the CDS spread data from November 2015 to August 2022, we estimate the network structure of sovereign and corporate credit risk. The results show that sovereign and corporate credit risks are interconnected significantly, particularly with respect to the banking sector where FX-related transactions are made. Since 2022 when the monetary policy has become contractionary, such credit risk interconnectedness seems to be strengthened because of greater common exposure.

This study aims to identify the impact of the audit approach based on business risks (i.e., external environment risk, operations risk, information risk) in reducing unsystematic risks (i.e., operational risk, credit risk, liquidity risk, capital risk, and administrative risk) in Jordanian banks. To reduce the effect of unsystematic risks and, thus, improve banking performance, an audit approach based on business risks has emerged. To achieve the objectives, this study relied on descriptive statistics and the regression approach to study twenty-five Jordanian banks. The researcher used the intentional sampling method represented by employees of the accounting, financial and control departments in Jordanian banks. Seventeen banks contributed to the study, with a percentage of 68%, totaling 356 employees. A questionnaire was designed to obtain the data, and due to homogeneity among the sampling members, a purposive sample was drawn and 300 questionnaires were distributed. The results of the study found a statistically significant effect of the audit approach based on business risks with its combined dimensions on reducing unsystematic risks in Jordanian banks. The results of the study also found a statistically significant effect of the business risk-based audit approach with its combined dimensions on reducing operational risks in Jordanian banks.

The implications of bank-specific risks and macroeconomic risks on the growth, profitability, and stability of Islamic and conventional banks are examined and compared in this article. The study also investigates whether corporate governance mitigates the effects of both bank-specific and macroeconomic risks on Islamic and conventional banks' development, profitability, and stability. For the period 2007-2019, we examined a panel data set of 22 banks in Pakistan, including both Islamic and conventional banks. We discovered considerable evidence that both bank-specific risks and macroeconomic risks have negative effects on the growth, profitability, and stability of Pakistani banks using a dynamic panel data estimator, the two-step Generalized Method of Moments (GMM) approach. Furthermore, the findings show that bank-specific and macroeconomic risks have different consequences in both types of banking. The impacts of liquidity risk, operational risk, capital risk, inflation risk, and exchange rate risk are higher for Islamic banks than for conventional banks. Conventional banks, on the other hand, are more vulnerable to credit risk and interest rate risk. Finally, the findings show that good corporate governance reduces the negative consequences of both categories of risks on bank development, profitability, and stability. This is true for Islamic and conventional banks alike.

Independent guarantee is a creation of the need from the both sides, i.e. the applicant (principal debtor) and the beneficiary (creditor). The former used to have to deposit cash in favor of the beneficiary in case of his default, which laid a burden on his liquidity while the latter still wanted to have the equivalent to cash. Independent guarantee satisfied the both parties by freeing the applicant of a deposit and maintaining the beneficiary's right at the same time. The fact that independent guarantee has three payment mechanisms is not widely known to the public. They are (i) payment on first demand, (ii) payment upon submission of third-party documents, (iii) payment upon submission of an arbitral or court decision. From the applicant's point of view, the order in his favor is (iii), followed by (ii) and (i). As there shouldn't be a case where one party is at a disadvantage against the other, useful insight is being sought for the benefit of the applicant. First, the applicant can offer his intention to provide a payment mechanism (ii) or (iii) rather than (i) if he must deliver it. Second, if the beneficiary still wants to have (i) and the applicant is in a position not to reject it, the latter should thoroughly check any provisions that may work against him later. Third, the applicant could use counterbalancing provisions in underlying contract to cope with protective clauses in the guarantees. Forth, the applicant should review the beneficiary's sincerity to prevent unfair calling risks. The applicant may use an ECA(Export Credit Agency) in his country to which he can transfer not only unfair calling risks, but also political risks. On the other hand, a bank needs to keep the following advice in mind. The foremost important thing for the bank not to forget is that it provides a guarantee as a service provider, not as a responsible party for the feasibility of the project, etc. Credit risk of the applicant should require the greatest attention when issuing a guarantee: the bank should look into the possibility that it can procure immediate reimbursement from its customers after payment to the beneficiary. Second, the applicant's ability to complete the project should be reviewed by checking its track records, techniques and reputation, etc. Third, the bank may also use an ECA to cover the beneficiary's unfair calling risks as well as political risks. In the case of Korea, as Korea Export Insurance Corporation(KEIC) can cover all the risks mentioned above, the bank could use its service called 'Export Bond Insurance.' What's better for the bank is that ECA cover can enhance the bank's asset quality by putting it zero on its risk weighted asset.

The purpose of this research was to investigate the perception of financial risks and expenditures for insurance by household characteristics. Data were collected from 598 housewives by online survey on Dec., 2001. Results indicated that respondents had perceived the risk of unemployment most among three types of risks. Household characteristics reflecting financial needs in emergency case had positive effects on the perception of risks, and hence the expenditures for insurance, in general. On the other hand, the level of emergency preparation had negative effects on the perception of risks and the expenditures for insurance. However, only credit-related risk had a positive relationship with the expenditures for insurance.
