The purpose of this study was to identify the effect of living cost reduction through social welfare services and programs and to suggest the further ways of saving living cost for low-income households. For the research purpose, low-income household type was divided into three representative groups such as senior household, household with school-aged children, and household with the disabled based on the literature review. Four case households which live in permanent rental apartment in Seoul were selected as research subjects. During March 14~April 10, 2010, each household was interviewed to examine the details of monthly income and expenditure structure and types of welfare services receiving. Although some differences exist among cases, there was a definite living cost reduction effect through welfare services and programs from 12% to 150%. Household with school-aged children required diversified education programs corresponding to the children's age. Meanwhile, households including senior and the disabled indicated the necessity of convenient transportation system.

This study investigates the effect of life settlement on the monopolistic insurance market. In particular, we consider liquidity cost, which is the cost incurred to the insurer to meet the request of surrender, and trading cost, which is the transaction cost of the policyholders for the settlement. We first show that the introduction of a life settlement can increase insurance demand and enhance consumer welfare even when the trading cost is higher than the liquidity cost. That is, even if the settlement market is less efficient than the insurance market, both insurance demand and consumer welfare can be increased. Second, the insurer's profit can also be increased when settlement is introduced because not only can the insurer save the liquidity cost but also the demand of insurance increases. Lastly, insurance demand does not always decrease when both costs increase. Depending on the population distribution over the liquidity risk, the demand of insurance can be increased or decreased.

본 연구는 외부비용의 한 항목인 유지비용을 내부화하여 이에 따른 사회적 후생의 변화에 대한 연구이다. 연구대상으로는 민자 고속도로, 고속국도, 그리고 일반국도 등, 도로여건과 통행요금이 다른 3가지 노선이 경쟁하고 있는 천안$\sim$논산간 노선을 선정하였다. 유료도로의 수요함수는 회귀분석을 통해 도출하였다. 최선 가격설정법의 현실적용 어려움을 고려하여 유지비용을 통행요금에 재반영하는 방법으로 차선 가격설정법을 적용하였다. 유지비용을 통행요금에 반영함으로써, 노선별 통행량 변화에 따른 사회적 후생뿐만 아니라, 통행수입금의 변화 측면도 함께 연구하였다. 분석결과, 차선 가격설정법을 적용함에 따라 사회적 후생의 변화는 작은 차이를 보였으나, 재정적인 측면에서는 고속국도에 유지비용을 반영하였을 경우 연간 약 130억 원의 재정적인 효과가 있어 국가 재정 지원 감소에 기여할 것으로 분석되었다.

Purpose - This paper studies the welfare impacts of behavior-based price discrimination (BBPD) when firms are asymmetric in quality improvement costs. Design/methodology/approach - To this end, we consider a differentiated duopoly model with an inherited market share, where firms first make quality decisions and then compete in prices according to the pricing scheme, namely, uniform pricing or BBPD. Findings - We show that BBPD increases social welfare relative to uniform pricing if the firms' cost gap is large enough. This is because BBPD induces more consumers to buy a high-quality product than under uniform pricing, and because a low-cost firm's profit loss from BBPD decreases as the cost difference increases. Research implications or Originality - Our analysis offers policy implications for markets where BBPD raises antitrust concerns, and quality competition prevails.

본 연구에서는 한계비용 이론에 바탕을 둔 램지가격결정방식과 효율적요소가격결정방식을 이용하여 천연가스 가격체계의 이론적 모형을 도출함으로써 사회후생의 최적화를 달성하기 위한 국내 가스가격결정방식의 개선방향을 제시하였다. 사례연구를 통하여 국내 가스산업의 현행 원가보상방식, 램지가격결정방식과 효율적요소가격결정방식에 의한 가격간에 배분효율성과 사회후생을 비교 분석하였다. 배분효율성은 도시가스용의 경우에 원가보상방식이 램지가격결정방식 및 효율적요소가격결정방식에 비하여 높게 나타났으나, 발전용의 경우는 원가보상방식이 두 방식에 비하여 낮음을 알 수 있었다. 반면에 사회후생효과는 현행의 원가보상에 의한 가격결정방식보다 램지가격결정방식과 효율적요소가격결정방식을 적용하는 것이 보다 더 향상되는 것으로 나타났다.

The purpose of this study was to examine the relative deprivation of the households in poverty, comparing with the households in non-poverty, and to find out the characteristics of household groups by the level of relative deprivation. The data for this study was from the 6th Korea Welfare Panel Survey(KOWEPS), consisting of total 5,552 households. The results are as follows: There were statistically significant differences in the objective cost of living, the subjective minimum cost of living, and the subjective adequate cost of living between households in poverty and households in non-poverty. There was statistically significant difference in the relative deprivation between households in poverty and households in non-poverty. Poverty was the factor for the relative deprivation of households.

The purposes of this study were to: a) examine charateristics of foodservice manaegment practices; b) investigate characteristics of recipients; c) analyze foodservice systems; and d) provide feedback for the efficient and effective foodservice management of welfare institutions for the homeless in Korea. A total of 27 sites was analyzed by questionnaire survey. Satatistical data analysis was completed using the SPSS package program for descriptive analysis. As results of site recipients' characteristics, 69% of total sites were males and 31% were female recipients. Average 60% of recipients were from 30 to 50 years old. Major diseases of recipients were high pressure, and obesity. According to the result of foodservice system analysis, the average meal cost per day was about 2,943 won and average food cost percentage was 29%. Average number of meals per day was about 600 meals. Mostl sites had one dietitian and 48.1% of sites had one cook as a full-time employee. In the part of procurement, dietitians were major chargers of sites for purchasing foods. Major purchasing method was the order and delivery contract. About a half of sites used cycle menu system and standardized recipies. Most of sites had recipients' survey systems for evaluating meal satisfaction. Dietitians at sites had problems on lack of cooking professionals and low meal cost budget for providing higher quality of foods to cure recipients. The results suggested that financial and systematical supports by the government would be very necessary to meet the goal of nutritional balanced meal services.

Commonality strategy is a popular design practice in designing a product line as it enables the firm cost saving and simplification in design, manufacturing, and distribution processes. However the issue of commonality has been mostly analyzed from a profit maximizing firm's perspective and, to our knowledge, there is no literature that deals with the issue from a different perspective. in this paper, we consider the issue of commonality strategy from a social welfare maximization perspective, and argue that commonality strategy used in designing of public goods can bring certain benefits not just for a firm but also for consumers, i.e., for society as a whole. While we assume certain cost saving in production process due to economies of scale under commonality strategy, we conceptualize two different effects of commonality strategy, utility effect due to cost saving and weighted-averaging effect, and show how these two effects interplay to determine the design of common attribute and desirability of commonality strategy. We also discuss how the implementation of commonality strategy differs under different objectives of a product line designer : social welfare and firm's profit maximization.

The government has implemented housing welfare policy to ease low-income households' housing-cost burden and improve their quality of life. However, public housing residents and housing choice voucher recipients still show a high level of housing-cost burden. In this regard, this study aims to provide policy implications for current housing welfare policy by analyzing and comparing the factors that determine both subsidized and unsubsidized households' housing-cost burden. For the empirical analysis, this study uses "2017 Korea Housing Survey" and divides groups into public housing residents, housing choice voucher recipients, and unsubsidized low-income renters. We compared the level of housing-cost burden by employing t-test and chi-squared analyses and the factors affecting the housing-cost burden by employing logistic regression analyses between the three groups. According to the empirical analysis, the housing cost is the most burdensome for the housing choice voucher recipients group, followed by the unsubsidized low-income renters and public housing residents. In addition, the factors affecting housing-cost burden are different between the three groups. In case of public housing residents, housing characteristics usually affect the housing-cost burden. For housing choice voucher recipients and unsubsidized low-income renters, both housing and household characteristics influence the housing-cost burden. Looking at the detailed factors, except for the housing tenure and regional average rents that are common factors for all groups, the amount of deposit is an important factor for public housing residents, and household employment status is an important factor for both housing choice voucher recipients and unsubsidized low-income renters. The policy implications of this study are as follows: First, it is necessary to review the blind spot of the current housing welfare policy. Second, a comprehensive review of the housing choice voucher program is required. Third, it is necessary to make policy efforts to ease the level of housing-cost burden for renters. Fourth, a program is needed for those public housing residents who need a deposit support. Fifth, there should be further assistance with public housing for the poorest people.

Background: To assess the treatment pattern and expenditure incurred by cancer patients undergoing treatment at government tertiary hospitals in India. Materials and Methods: A cross-sectional study of 508 cancer patients randomly selected from tertiary cancer hospitals funded by central/state governments located in major cities of five states in India, namely Kerala, Maharashtra, Rajasthan, West Bengal and Mizoram, during March - May 2011 was conducted. Information related to direct costs, indirect costs and opportunity costs incurred on investigations and treatment, major source of payment and difficulties faced by patients during the course of treatment was collected. Results: About 45% of the patients used private health facilities as the first point of contact for cancer related diseases as against 32% in public hospitals. About 47% sought private health facilities for cancer investigations, 21% at district/sub-district hospitals, and about 4% contacted primary health care facilities. A majority of the patients (76%) faced financial problems while undergoing treatment. Conclusions: The results highlight the importance of involving the primary health care system in the cancer prevention activities.
