This study attempted to identify the factors related to life insurance focusing on two different types of life insurance： term life insurance and cash-value life insurance. Based on the human capital, bequest motives theories, and decision under risk, a conceptual framework was developed. The results showed a support for the conceptual framework indicating that human capital, bequest motives as well as attitude toward risk were important factors in predicting each of life insurance ownership. In addition, the factors related to each type of life insurance were different. For term life insurance, the variables representing households' bequest motives were found to play an important role while the variables reflecting human capital theory had significant impact on cash-value life insurance holding.

This paper researches conservative value evaluation of rural tourism villages with "CVM(Contingent Valuation Method)" focusing on visitor to offer the guide for preservation and management in landscape of rural tourism villages based on critical consciousness for conservation and utilization by regional development. The option value is 37,624won(36.7%), the bequest value is 34,856won(34.0%), existence value is 30,073 won(29.3%), and overall average willingness to pay of conservation value is 102,517won(100.0%) for conservative value of sesim-village in Kyung-Ju. The results show that landscape of rural tourism villages has great value historically and culturally. In conclusion, it suggested that planners and staffs of rural tourism villages recognize that it is positively necessary to be considered not only multiple landscape index but also conservation policy in process of development planning in rural tourism villages.

The purpose of this paper is to analyze the value of stone fences in Jeju Island. The result that executes attitude survey to local resident and visitor can be summarizing as following. First are the function and the value of Jeju traditional stone fences. Local resident favored the culture heritage succession and evaluated its' usage Value highly. Visitors also have favored rural landscape offer function and evaluated inheritance value (Bequest Value) highly. Secondly, 80.5% of visitors, 78.1% of local resident have formed opinion about preservation of traditional stone fences. But the Willingness to pay for traditional stone fences fund was raised by 38.6% in local resident and 55.7% in visitor.

The purpose of this study was to examine factors related to the purchase of cash-value life insurance of households. Based on human capital and bequest motive theories of the demand for life insurance, this study developed a conceptual model of the demand for life insurance of households. In addition, in order to capture the beneficiaries' preference and expected lifetime utility, expected future financial needs were included in the conceptual model. Using Heckit analysis, the model was estimated by two stages. The results supported that human capital, bequest motives and expected future financial needs were significant factors on both decision to have insurance and the mont of insurance. Specifically, if the household's head expected to have a higher potential in the future, the household was more likely to have insurance. If a household had dependents, the household was more likely to have insurance. As income or monthly expenditure increased, the probability of haying insurance and the amount of the insurance increased However, savings or social insurance were positively related to the purchase of insurance.

In insurance, the surrender rate is an important variable that threatens the sustainability of insurers and determines the profitability of the contract. Unlike other actuarial assumptions that determine the cash flow of an insurance contract, however, it is characterized by endogenous variables such as people's economic, social, and subjective decisions. Therefore, a microscopic approach is required to identify and analyze the factors that determine the lapse rate. Specifically, micro-level characteristics including the individual, demographic, microeconomic, and household characteristics of policyholders are necessary for the analysis. In this study, we select panel survey data of Korean Retirement Income Study (KReIS) with many diverse dimensions to determine which variables have a decisive effect on the lapse and apply the lasso regularized regression model to analyze it empirically. As the data contain many missing values, they are imputed using the random forest method. Among the household variables, we find that the non-existence of old dependents, the existence of young dependents, and employed family members increase the surrender rate. Among the individual variables, divorce, non-urban residential areas, apartment type of housing, non-ownership of homes, and bad relationship with siblings increase the lapse rate. Finally, among the financial variables, low income, low expenditure, the existence of children that incur child care expenditure, not expecting to bequest from spouse, not holding public health insurance, and expecting to benefit from a retirement pension increase the lapse rate. Some of these findings are consistent with those in the literature.

본 논문은 금강 하구의 직 간접적 사용과 관련되지 않는 비사용가치를 조건부가치측정법(CVM)으로 추정하였다. 조건부가치측정법 설문에서 금강 하구의 비사용가치만을 추정하도록 유도하였고, 지불의사금액을 도출하기 위한 제시금액에 대한 양분선택적 응답 결과를 Turnbull 비모수적 추정법을 적용하여 분석하였다. 모형의 추정 결과로부터 Turnbull 하한 평균 지불의사금액을 구하면, 단일양분선택형 CV 자료에서는 5,822원(95% 신뢰구간 5,295원 ~ 6,349원)이고 이중양분선택형 CV 자료에서는 6,205원(95% 신뢰구간 5,701원 ~ 6,710원)으로 추정되었다. 따라서 본 연구에서는 두 추정치의 평균값인 6,014원(95% 신뢰구간 5,498원 ~ 6,529원)을 금강 하구의 연간 비사용가치 산정에 이용하였다. 이로부터 도출된 금강 하구의 비사용가치는 연간 연간 2,203억 원(95% 신뢰구간 2,014억 원 ~ 2,392억 원)에 이른다. 여기에는 유산가치 683억 원(95% 신뢰구간 625억 원 ~ 742억 원), 존재가치(고유가치) 580억 원(95% 신뢰구간 530억 원 ~ 630억 원) 및 선택가치 577억원(95% 신뢰구간 527억 원 ~ 626억 원) 및 대리소비가치 363억 원(95% 신뢰구간 331억 원 ~ 394억 원)이 포함되는 것으로 평가되었다.
