산업혁명 이후 기계로 만든 공산품이 시장의 대부분을 차지하고 있지만, 최근에는 장인의 노력, 품질에 대한 믿음, 제품의 희소성, 제품을 사용함으로써 얻는 자부심 등을 이유로 많은 소비자들이 같은 범주의 공산품보다 더 비싼 가격을 주고 핸드메이드 제품을 구매하고 있다. Etsy.com은 세계 최대 온라인 핸드메이드 플랫폼으로 2015년 4월 기업공개에서 2조원이 넘는 자금을 조달하면서 온라인 핸드메이드 플랫폼의 잠재력을 증명하였다. 그러나 실제 온라인 플랫폼 환경에서 이루어진 지능형 서비스 관련 선행연구들을 살펴보면 대부분 공산품만을 대상으로 하고 있어, 핸드메이드 제품에 대한 학술적 접근이 충분히 이뤄지지 않고 있음을 알 수 있다. 이에, 본 연구에서는 신호 이론과 온라인 플랫폼에서의 구매자-판매자 관계 특성에 대한 선행연구를 바탕으로 온라인 핸드메이드 플랫폼에 적용 가능한 핵심 특성요인인 입점 상점 특성(명성, 규모)과 입점 상점 관계특성(정보공유, 관계기간)을 도출한 후, Etsy.com 웹사이트에서 웹 하베스팅 방법으로 수집된 데이터를 이용하여 실증 분석하였다. 분석 결과, 입점 상점 특성 가운데 명성과 규모, 그리고 입점 상점 관계특성 가운데 정보공유는 입점 상점의 총 판매량에 유의한 영향을 주는 것으로 확인되었다. 또한, 입점 상점 특성 중 명성, 그리고 입점 상점 관계특성 중 관계기간은 입점 상점의 가격 프리미엄에 유의한 영향을 주는 것으로 나타났다. 본 연구의 결과로 온라인 핸드메이드 플랫폼에서 지능형 서비스 도입 및 운영을 위한 효과적인 관리 기준을 제시하고, 나아가 입점 상점이 핸드메이드 제품에 대한 판매량 증진 및 가격 프리미엄 극대화를 위한 실질적 전략 마련에 도움이 될 수 있기를 기대한다.

Environmentally friendly agricultural products(EFAPs) are on an increasing trend of supply, but not much enhancing the rate of consumption due to higher premiums and consumers' safety concerns. In order to enlarge the consumption of EFAPs and secure the income of the producing farmers, wholesale market should increase the treating amount of EFAPs and introduce traceability system for satisfying consumers' safety concerns. The purpose of this study is to present strategies of traceability system in wholesale market for environmentally friendly agricultural products. For this purpose, current traceability systems that are introduced and managed by government and private association are examined. For the successful management of the EFAPs' traceability system in wholesale market, the trading system, the functions of wholesale market, the level of consumers' safety concerns, and the managing costs should be considered.

This study provides the empirical results of the customers' necessity and intentions of purchasing weather index insurance using survey of asking the customers' recognition about weather insurance. In this article, we discovered that not only the customers' past experience of loss but also the extent of damage and the effects that change in weather would have on their firm are positively related to an intention to purchase weather index insurance. In addition, the level of premiums was significantly higher for the highly-intended group of willing to purchase weather index insurance than the comparison group.

Customer satisfaction is undoubtedly one of the top strategic issues in the new decade. Today, many organizations are rushing to become more customer focused. A key component of many initiatives is the implementation of customer satisfaction software. In this paper, we provide a case study for customer satisfaction management in a city gas company. The three issues include the plan for giving premiums and the development of a happycall system and a web-based measurement system for customer satisfaction.

Credibility models are actuarial tools to distribute premiums fairly among a heterogeneous group of policyholders. Many existing credibility models can be expressed as special cases of linear mixed effects models. In this paper we propose a nonlinear credibility regression model by reforming the linear mixed effects model through kernel machine. The proposed model can be seen as prediction method applicable in any setting where repeated measures are made for subjects with different risk levels. Experimental results are then presented which indicate the performance of the proposed estimating procedure.

The contingent convertible bond (or CoCo) is designed as a bail-in tool, which is written down or converted to equity if the issuing bank is seriously troubled and thus its trigger is activated. The trigger could either be rule-based or discretion-based. I show theoretically that the bail-in is less implementable and that the associated bail-in risk is lower if the trigger is discretion-based, as governments face greater political pressure from the act of letting creditors take losses. The political pressure is greater because governments have the sole authority to activate the trigger and hence can be accused of having 'blood on their hands'. Furthermore, the pressures could be augmented by investors' self-fulfilling expectations with regard to government bailouts. I support this theoretic prediction with empirical evidence showing that the bail-in risk premiums on CoCos with discretion-based triggers are on average 1.13 to 2.91%p lower than CoCos with rule-based triggers.

본 연구에서는 한국의 주식시장을 대상으로 환위험 프리미엄의 존재여부와 기업특성과 환위험 프리미엄의 관계가 어떠한지를 분석하였다. 분석결과 전체 표본기간에서는 유의적인 환위험 프리미엄의 존재를 확인할 수 없었으나, 90년 1월에서 96년 12월까지의 기간에서 환위험 프리미엄이 유의적으로 존재함을 확인하였다. 시뮬레이션을 이용한 환위험 프리미엄과 기업특성의 관계에 대한 분석결과는 기업의 특성별로 환노출에 차이가 있음을 보여주어, 기업의 경영활동 특성에 따라 환위험 프리미엄에 차이가 있음을 나타내고 있다. 특히, 수입비율이 높은 기업에서 환위험 프리미엄이 높게 나타났으며 수출비율은 환위험 프리미엄과 큰 관련이 있다고 할 수 없었다. 이는 환노출과 수출활동과의 관련성을 보고한 기존의 선진국들을 대상으로 한 연구 결과와는 매우 다른 것이다. 이리한 연구결과는 투자자들이 주식투자에서 요구하는 수익률에 해당기업의 환위험의 특성을 반영하고 있음을 나타낸다. 또한 기업들이 환위험의 헤지전략을 수립하는 과정에 기업의 경영활동의 특성을 구체적으로 고려할 필요가 있음을 시사하는 것이다.

The excessive demand for universities in metropolitan areas as a result of location premiums and regulated admissions quotas diminishes the competition between universities and the incentive to enhance educational performance to attract more students. Cases in point are the lower graduate employment rates (a measure of educational performance) of universities in metropolitan areas compared to those in non-metropolitan areas despite higher quality students. Additionally, the graduate employment rates of non-metropolitan universities are influenced by educational input factors such as an increase in the percentage of courses taught by full-time faculty, while those of metropolitan universities are contingent merely on enrollees' entrance scores. Ergo, a structure that revitalizes the competition between universities and encourages them to improve their educational services must be established in order to enhance the quality of higher education.

Over the past decades, the Lee-Carter model [1] has attracted much attention from various demography-related fields in order to project the future mortality rates. In the Lee-Carter model, the speed of mortality improvement is stochastically modeled by the so-called mortality index and is used to forecast the future mortality rates based on the time series analysis. However, the modeling is applied to long time series and thus an important structural change might exist, leading to potentially large long-term forecasting errors. Therefore, in this paper, we are interested in detecting the structural change of the Lee-Carter model and investigating the actuarial implications. For the purpose, we employ the tests proposed by Coelho and Nunes [2] and analyze the mortality data for six countries including Korea since 1970. Also, we calculate life expectancies and whole life insurance premiums by taking into account the structural change found in the Korean male mortality rates. Our empirical result shows that more caution needs to be paid to the Lee-Carter modeling and its actuarial applications.

Generalized linear models and generalized linear mixed models (GLMMs) are fundamental tools for predictive analyses. In insurance, GLMMs are particularly important, because they provide not only a tool for prediction but also a theoretical justification for setting premiums. Although thousands of resources are available for introducing GLMMs as a classical and fundamental tool in statistical analysis, few resources seem to be available for the insurance industry. This study targets insurance professionals already familiar with basic actuarial mathematics and explains GLMMs and their linkage with classical actuarial pricing tools, such as the Buhlmann premium method. Focus of the study is mainly on the modeling aspect of GLMMs and their application to pricing, while avoiding technical issues related to statistical estimation, which can be automatically handled by most statistical software.
