Following the methodology of Ben-Rephael, Kadan and Wohl (2015), this paper examines whether firm-level liquidity premium exists and whether the premium exhibits a long-term trend in the Korean stock market. The results show that over the whole sample period (1998-2018), a liquidity premium of 0.083% exists in the cross-section of stocks. Interestingly, the pricing of liquidity declines significantly over the sample period. Sub-period analysis indicates that liquidity is priced mainly in the first sub-period (1998-2004) with a significant monthly premium of 0.304%, while the pricing of liquidity becomes weaker or insignificant in the second (2005-2011) and the third (2012-2018) period. I also find that the significance of the liquidity premium in the first period is attributed to small stocks. To explore underlying reasons that might affect the decline in the liquidity premium, I decompose liquidity premium into the product of firm-level liquidity and the sensitivity of expected stock returns on liquidity. The results reveal that the long-term decline is explained by both an increase in firm-level liquidity and a decrease in the sensitivity of expected returns on liquidity.

The rapidly aging trend of Korea is a major factor that threatens the sustainability of the long-term care insurance system. Therefore, looking at how Japan and Germany mitigated the financial burden when they managed similar long-term care insurance systems will provide important implications for improving the Korean system in the future. The study was conducted using the literature review method, and the "country" was set as a unit for the case analysis. The three countries selected are Korea, Japan, and Germany. Recently in Korea, the insurance premium rates of all subjects have been rapidly rising, which can exacerbate the issue of intergenerational equity. On the other hand, Japan has responded to the aggravating finances for long-term care insurance due to aging by raising coinsurance for selected groups like the wealthy elderly. Germany is selectively raising the insurance premium rates by additionally increasing the premium rate for childless recipients. A more preventive and quality-oriented care service plan can be promoted by referring to the recent changes in Japan and Germany. In addition, a more effective and selective increase in payment burden in Japan and Germany could be considered in response to a recent equity issue in Korea.

This paper aims to find a reasonable solvency margin system in non-life insurance industry and also to evaluate the appropriateness of the current solvency margin regulation system in Korea. The current solvency margin system in Korea, based on EU's solvency margin model, was introduced during the 1997 financial crisis. The solvency requirement is not based on non-life insurer's risk, but simply on written premiums. The current solvency margin for general insurance, such as fire, marine, and automobile insurance, is determined by the greater between a premium-based amount and a claim-based amount, where the premium-based solvency margin is calculated by multiplying the net written premium for the preceding year by the premium based solvency margin ratio. Also, the amount of solvency margin for long term insurance is set at 4% of the policy reserve of the long term insurance. Still, there exist many differences between the current solvency margin regulation system in Korea and EU's model. This paper focuses on the rationality of the solvency margin regulation system, and compares the current system in Korea with EU's model and the RBC(Risk Based Capital) system in U.S. and Japan. Finally, this paper suggests a more specific and reasonable solvency margin system to be developed in Korea.

In this paper, we study an asymptotic behavior of the finite-time ruin probability of the compound Poisson model in the case that the initial surplus is large. To compare an exact ruin probability with an approximate one, we place the focus on the exact calculation for the ruin probability when the claim size distribution is regularly varying tailed (i.e. exponential claims and inverse Gaussian claims). We estimate an adjustment coefficient in these examples and show the relationship between the adjustment coefficient and the safety premium. The illustration study shows that as the safety premium increases so does the adjustment coefficient. Larger safety premium means lower "long-term risk", which only stands to reason since higher safety premium means a faster rate of safety premium income to offset claims.

This paper surveys research since the 1990s on the ability of the yield spread and its components (i.e., expectation spread and term premium components) for future economic activity, and also conducts an empirical analysis of their forecasting ability using the yield data of Korean government bonds. This paper's survey, particularly for the US, shows that the yield spread has significant predictive power for some macroeconomic variables, but since the mid-1980s, its predictive power seems to have declined, possibly due to stronger inflation targeting. Next, this paper's empirical analysis using Korean data indicates that the yield spread, and the term premium component in particular, has significant predictive power for industrial production (IP) growth, consumer price index growth, and the IP gap. An out-of-sample analysis shows that the prediction equations are unstable over time, and that in predicting IP growth, the yield spread decomposition makes a significant contribution to the prediction of IP growth.

Since 2006, local governments in Korea have been providing premiums for social insurance, such as the National Health Insurance System, for the health care of local residents. The purpose of this study is to analyze the content of self-governing legislation that defines these policies. The method of conducting the research was based on the articles of the ordinance related to the 'public health insurance premium' of the self-governing statutes published on the website of the National Law Information Center. As of May 2019, 201 municipalities have enacted ordinances to support public health insurance premiums. In the case of state local governments, 8 out of 17 were found, and in the case of basic local governments, 193 out of 226. The constitution of the ordinance consisted of purpose, time of enactment, type of social insurance premium, object of social insurance premium, amount of social insurance premium support, method and process of social insurance premium support, time of social insurance premium support. This study analyzed contents of these articles. Finally, this study presented issues that could be controversial from the policy and legal viewpoints and suggestions for improvement.

The purpose of this study was to analyze customer attraction effects of restaurant promotion for kids. The questionnaires were distributed to 300 parents who have children under 12 years old and a total of 269 questionnaires were collected and used in analysis(usage rate 90.0%). The data was analyzed using SPSS 12.0 for descriptive analysis and paired t-test. The major results were as follows; First, customers mainly got information on coupon from mail. In case of premium and membership, the information was obtained when customers were visiting restaurants. Second, among the types of promotion for kids, coupon was mostly preferred by customers. 'Discount coupon' for the coupon, 'free gift' for the premium and 'pay-back' program for the membership were more preferable than other types of kids promotion. Third, A 'discount coupon' was more effective than 'free coupon'(p<.0l) in term of customer inducement. In case of premium, 'free gift' was more effective than 'lottery'(p<.05) and in case of membership, the customer attraction effect was not significantly different according to the types of membership. In case of coupon and membership, it was more effective in family restaurant than fastfood restaurant(p<.05), but the effect of premium was not significantly different in family vs fastfood restaurant. The results of the study revealed that 'coupon' was the most preferred type of promotion for kids and specifically customers preferred 'discount coupon', 'free gift' and 'pay-back program'.

This study identifies how the luxury brand marketing mix affects customer equity drivers and suggests intangible equity management strategies so that companies can make long-term profits through luxury brands based on empirical studies of Korean luxury consumers. The results of the study are as follows: First, this study classified the properties that use 8 key factors (product integrity, heritage, exclusivity, premium image, environment and consumption experience, premium price, luxury communication strategy, and brand signature). Second, it shows that product integrity and luxury communication strategy have a positive effect on all customer equity drivers, that brand signature has a positive effect on value equity and brand equity, and that premium price has a negative effect on relation equity. It is important to provide products and services equipped with high quality and luxurious designs based on excellent craftsmanship in order to establish brand equity and value equity. Brand identity needs to be maintained and unique brand signatures need to be developed based on the long history of luxury brands against a traditional backdrop. A diversified communication strategy improves brand recognition while playing a part in facilitating brand association and brand image. In order to improve relationship equity, actions such as a loyalty program to strengthen brand loyalty, need to be taken as well as measures to maintain and enhance customer trust through a reasonable price strategy.

Despite the importance of the insurance business for financial and economic development, few studies have looked at the factors that influence its growth. This research adds to the body of knowledge by empirically examining the impact of numerous factors on the development of the insurance business in 15 Middle East and North African (MENA) countries from 2000 to 2017. The study looks at macroeconomic, demographic, and institutional factors as potential drivers of the insurance industry's growth, with the insurance premium as a percentage of GDP as the dependent variable. All variables are stationary at the first difference, according to the IPS panel unit root test. The Pedroni residual cointegration test, Kao residual cointegration test, and Johansen-Fisher panel cointegration tests are then used to look for long-run associations. The cointegration tests strongly suggest that the insurance premium and the various variables have long-run correlations. Findings from the Fully-Modified OLS imply that GDP per capita, gross capital formation, and the KOF economic globalization index have a positive long-term impact on the insurance business. The insurance business is also driven by combating corruption and the rule of law. The population and regulatory quality, on the other hand, have no significant impact.

We examine the motives of foreigner's investments in the Korean bonds by maturity and try to prove that market impacts are different by their investment maturity. Foreign investors initially focused on short-term bonds, but have expanded to mid- to long-term bonds since 2010. The previous studies found that covered interest arbitrage was the main reason for foreign investment. However, there should be some other reasons as their investment in mid- to long-term bonds might have nothing to do with arbitrage. In the empirical analysis, we found that foreign investment in bonds with less than 2 year maturity is driven by arbitrage as previous studies. However, investment in bonds with 2-5 year maturity is sensitive to the FX volatility and the stock market performance compared with the U.S. and investment in bonds with more than 5 year maturity is driven by the CDS premium differential between Korea and PIIGS countries. The more foreigners have invested mid- to long-term bonds, the stronger downward pressure has been on the bond yields. In addition, foreign investors indirectly affected the spreads. Meanwhile, the government should prepare some policy measures since concerns over side effects such as the Korean won appreciation and an abrupt capital outflow are arising.
