Objectives: People are living longer, but often with diseases or chronic conditions. As a consequence, interest in resolving insurance blind spots is growing. This study provides substandard risk-relevant statistics to help substandard risks who are likely to fall in insurance blind spots obtain insurance coverage, such as the reimbursement of medical costs, as well as to stimulate insurance product development. Methods: This study uses National Health Insurance Service (NHIS) cohort data to determine the relevant statistics. The incidence rates of severe diseases are derived and compared against standard risks to establish a set of relative risk factors. These incidence rates of standard and substandard risks are then compared. Results: Currently, an individual's cancer history is used in the underwriting process for simplified issue insurance. However, underwriting focusing on hospitalization and procedures related to serious illnesses could lower premiums for substandard risks. Moreover, the statistical results could be used to expand the coverage of health insurance products. Conclusions: This study's relative risk factors can be used to derive simplified issue premium rates for substandard risks. They can also be used to implement discount and loading schemes for medical reimbursement insurance and help insurance companies implement proactive risk management.

Purpose: This study aims to investigate the impact of auditor-client traffic convenience on accrual -based and real earnings management of the client firms. Research design, data and methodology: Using a sample of firms listed in Shanghai and Shenzhen Stock Exchanges over the period of 2007 to 2018, this paper empirically investigates the association between auditor-client traffic convenience and earnings management. We use three measures of auditor-client traffic convenience: railway traffic convenience, expressway traffic convenience, and air traffic convenience. The accrual-based earnings management is measured by abnormal accruals estimated by industry and year using the Modified Jones Model. Results: Findings indicate that traffic convenience is conducive to detecting and restraining positive accrual earnings management and real earnings management. After changing the measurement of independent variable and dependent variable, including potential omitted variables, the results are statistically unchanged. Further, the research shows that traffic convenience can not only improve audit quality, but also lead to higher fee premiums. Auditors didn't share with clients the cost reduction benefits caused by traffic convenience. Conclusions: Traffic convenience provides auditors with easy access to the client firms, alleviating the information asymmetry and improving corporate earnings quality. The findings have implications for regulators, audit practitioners and stakeholders.

The objective of this study is to analyze the value of attributes of agricultural products in school food service using hedonic price model and choice experiment. In the case of potatoes, bean sprouts, and tomatoes, environment-friendly agricultural products rather than conventional ones, and domestic price premiums exist rather than Chungnam. The higher the price, the higher the margin rate. Conventional agricultural products were more profitable than environment-friendly ones, and domestic products were more profitable than Chungnam. In consumer preferences, environment-friendly agricultural products are preferred over conventional agricultural products and local products (Chungnam, Cheonan, Asan) rather than domestic ones. This is the opposite result of the Hedonic price model estimation that Chungnam has a lower price premium than domestic in the case of origin. This study is meaningful by analyzing the attribute value of agricultural products used for school meals in Chungnam and comparing them with the willingness to pay consumers. With the results of this study, it is necessary that discussions on supplementing the value of local products used in Chungnam school food service.

Purpose: Research on equity carve-outs is necessary because the market has realized that they lead to holding company discounts by double counting, which can only be observed in the Korean market. Considering the differences in the SSG.com equity carve-out compared to previous cases in terms of business strategy, this study contributes to the literature by examining the effects on shareholder value in the Korean distribution industry. Research design, data, and methodology: This study investigated literature, analyst reports, and news articles to examine the causes of holding company discounts and analyze the SSG.com equity carve-out. Results: The monopoly of holding companies' listing premiums is the main cause underlying holding company discounts from equity carve-outs. Protections for minority shareholder value are challenging owing to the complexity of the process of acquiring rights, the short exercise period, and additional costs. Therefore, the motivation for equity carve-outs should be to increase overall shareholder value. Conclusion: By analyzing the reasons for holding company discounts in the Korean distribution industry, this study provides recommendations for improving shareholder value.

Huazheng ESG level data and QIANZHAN database Using corporate financial data, a total of 500 samples were selected through correlation analysis and linear regression analysis with SPSS23 to analyze the effect of ESG on Return. As a result of the analysis, first, the impact on stock returns was found to be a significant positive (+) value for ESG integrated ratings and ratings by E (environment), S (social), and G (governance) sectors, confirming that ESG ratings have a positive mold of corporate stock returns. Currently, the world's major economies have proposed sustainable development strategies and "carbon neutral" goals. Development strategies are very consistent with ESG concepts, and companies that agree and execute ESG concepts may have higher ratings than other companies in the same industry, resulting in certain evaluation premiums. In addition, capital market performance in recent years shows that companies with ESG concepts or "carbon neutrality" concepts are generally considered to have higher growth potential and stronger anti-risk capabilities in the market. For listed companies, they should focus on ESG investment, improve ESG performance, and actively disclose related information to investors. Improving ESG performance should deliver positive information to society, enhance corporate image, increase market confidence in the future development of listed companies, and positively improve corporate value to actively increase financial, financial, trading, and other aspects of negotiation.

Many multiple life insurance products consider benefits that are contingent on the combined survival status of two lives. To value premiums of the insurance products accurately, we need to consider the impact of the survivorship of one life on another. To show a dependence relation between married couple, we calculate correlation coefficients by using married couples data from National Pension Service and the results show some positive dependence between them. Moreover, by analyzing the death after bereavement, we find a evidence that mortality rates increase after the death of a spouse and, in addition, that this phenomenon, the broken-heart syndrome, diminishes over time. The results of this study can support the method to calculate the premium of multiple life insurance reflecting more realistic joint mortality rates.

Objectives: The purposes of this study were to examine the status of children and adolescents with regard to enrollment in private medical insurance (PMI) and to investigate its influence on their utilization of medical services. Methods: The present study assessed 2973 subjects younger than 19 years of age who participated in five consecutive Korea Health Panel surveys from 2009 to 2012. Results: At the initial assessment, less than 20% of the study population had not enrolled in any PMI program, but this proportion decreased over time. Additionally, the number of subjects with more than two policies increased, the proportions of holders of indemnity-type only ('I'-only) and of fixed amount+indemnity-type ('F+I') increased, whereas the proportion of holders with fixed amount-type only ('F'-only) decreased. Compared with subjects without private insurance, PMI policyholders were more likely to use outpatient and emergency services, and the number of policies was proportionately related to inpatient service utilization. Regarding outpatient care, subjects with 'F'-only PMI used these services more often than did uninsured subjects (odds ratio [OR], 1.69), whereas subjects with 'I'-only PMI or 'F+I' PMI utilized a broad range of inpatient, outpatient, and emergency services relative to uninsured subjects (ORs for 'I'-only: 1.39, 1.63, and 1.38, respectively; ORs for 'F+I': 1.67, 2.09, and 1.37, respectively). Conclusions: The findings suggest public policy approaches to standardizing PMI contracts, reform in calculation of premiums in PMI, re-examination regarding indemnity insurance products, and mutual control mechanisms to mediate between national health insurance services and private insurers are required.
