본 논문에서는 오염배출 기업의 도덕적(道德的) 해이(解弛)(moral hazard)를 고려한 규제자의 강제정책(enforcement)에 관하여 분석한다. 또한 환경규제위반의 경우 일반적인 범죄와는 달리 의도적인 위반 이외에도 기술적 한계에 의한 불가항력적인 위반의 가능성이 있으므로 이를 고려하여 기업의 행태를 분석한다. 규제자의 강제 수단은 벌칙의 수준과 벌칙이 주어지는 기간으로 나누어 볼 수 있다. 벌칙의 강도와 벌칙이 주어지는 기간간의 관계는 사회후생을 고려한 경우 독립적이지 않고 서로 trade-off의 관계에 있다. 따라서 규제자는 벌칙의 구조를 결정함에 있어서 이러한 관계를 고려하여야한다. 크게 두가지의 선택이 있을 수 있는데 하나는 높은 수준의 벌칙과 짧은 벌칙 기간이고 다른 하나는 낮은 수준의 벌칙과 긴 벌칙 기간이다. 본 논문에서는 벌칙이 사회에 미치는 왜곡을 고려한 최적 벌칙 구조에 관한 분석을 목적으로 한다.

인구주택 센서스 즉, 인구주책 총조사는 일정시점을 기준으로 일정한 영역 또는 제한된 지역에 있어서의 모든 사람에 관한 개개의 특성과 경제 및 사회적 제반자료 및 주택실태에 관한 자료를 수집, 공표하는 일련의 과정(total process)을 말한다. [4] 이러한 인구주택 총조사는 인구통계 뿐만 아니라 모든 통계의 기초가 되며, 이구주택 총조 사의 정확도는 한나라의 통계발전 수준을 평가할 수 있는 척도가 된다. 우리나라에서는 인 구에 관한 대부분의 정보가 총조사를 원천으로 하여 작성 되어왔고, 장래 인구추계 및 인구 이동과 생명표에 관한 분석 등이 총조사 자료를 기초로 하여 이루어 지고 있기 때문에 인구 주택 총조사에 대한 의존도가 상당히 높게 나타나고 있다. 특히, 인구주택 총조사에서 수집, 생산되는 자료를 국가와 지역사회의 교육, 보건, 고용, 후생, 주택, 지역발전 등 각종 정책의 수립과 평가를 위한 기초자료로서 이용되는 등 그 중요성은 날로 커지고 있다. 그러나 산업 화와 급진적인 도시화 과정에서 수반된 높은 인구이동으로 인하여 인구주택 총조사의 실시 는 점차 복잡하고 어려워 지고 있다. 따라서 본고에서는 우리나라 인구주택 총조사의 발전 과 그 여건을 살펴봄으로써 인구주택 총조사의 중요성 및 곤란성을 인식하는데 일조하고자 한다.

In Korea mobile phone subscribers exceeded 1 million people in 1995, and ten million people in 1998. Prevalence of the mobile phone increased dramatically over 110% compared to the population. Almost every family members including children uses more than one mobile terminal. Mobile phone is obviously more necessary good than washer, vacuum cleaner and passenger car. Our daily life are conveniently positioned with mobile communication, but communication related costs including the price of the device and service charges become a big burden on the household. But the government does not seem to do the right role at the right time to prevent the market failure to maximize consumer welfare and social welfare through supporting fair competition. This principal-agent problem issues of mobile communication policies will be understood in perspective of public choice against joint use of the mobile communication network, number portability, separation of phone distribution and phone service, network neutrality, mobile phone subsidy since the early 1990s when mobile phone service was introduced in Korea.

In Korea mobile phone subscribers exceeded 1 million people in 1995, and ten million people in 1998. Prevalence of the mobile phone increased dramatically over 110% compared to the population. And all family members including children and students use one or two mobile terminal. Mobile phone is obviously necessary good more than washer, vacuum cleaner, passenger car. Our daily life with mobile communication are conveniently positioned, but communication related costs including the price of the device has become a big burden on the household. But the government does not seem to do the right role at the right time to prevent the failure of the market to further maximize consumer welfare and social welfare through fair competition. This principal-agent problems exist especially in perspective of joint use of the mobile communication network, number portability, separation of phone distribution and phone service and network neutrality among in mobile communication policies since the early 1990s up to now.

댐으로 인한 인공호수는 주위의 지역사회는 물론 타지역으로부터의 친수공간으로 활용될 수 있는 충분한 여건을 가지고 있음에도 불구하고 여러 가지 법적인 규제로 인해 극히 제한적으로 활용되고 있는 실정이다. 본 연구는 댐 호소의 관광자원화를 통한 친수공간의 확보와 국민복지증대 및 지역사회의 경제발전을 함께 도모할 수 있는 방안을 모색하였다. 만약 댐 호소에 대한 규제완화가 환경적인 영향이 크지 않고 경제적인 가치가 크다면 현 제도의 개선은 국민후생의 증대효과와 비점오염원의 관리를 통해 수질개선효과에 영향을 미칠 수 있음을 제시하였다.

본 논문에서는 전력 도매요금(현 전력거래제도에서의 시간대별 계통한계가격) 상승시, 고객의 부하절감을 유도함으로써 사회적 후생을 최대화 할 수 있는 상시부하관리 개념을 제안하였다. 2007년 계통을 대상으로 전력거래 모의프로그램인 P-POOL를 이용하여 경제적 측면에서의 효과를 분석하고 그 결과를 제시하였으며 본 결과는 향후 우리나라에서의 가격기반 부하관리 메카니즘 도입의 기초자료로 활용이 기대된다.

Recently the systematic change in the fire and disaster prevention administration, which was less studied than other administrative systems, has been in progress. In particular, the fire service demands are increasing and forms are diversified. The first thing you must do is to make up the fire service power according to the fire service demands. Such an allocation results in social welfare satisfaction. The purpose of this study is to investigate the determinants of fire service force. And this study investigates that fire service demand is affected by socioeconomic factor. To do this, this study reviews fire service force, the fire service demand, socioeconomic factor and financial factor. And this study sets up four hypotheses based on the theoretical backgrounds and the past research. The statistical method used for the verification of hypotheses are multiple regression analysis and structural equitation analysis. The analysis showed that fire service demand and financial factor were positive significant variable for fire service power. But socioeconomic factor was a negative significant variable. Also the analysis showed that social factor was a positive significant variable and economic factor was a negative significant variable for fire service demand.

The primary goal of this study was to investigate factors affecting job satisfaction of injured workers who returned to work. There are two types of injured workers' returning to work returning to pre-injury job and getting a new job. After separating the two types of workers we conducted the multiple regression analysis on the data from the Workers'Compensation Insurance Panel of the Korea Workers' Compensation and Welfare Service Corporation(2014). The sample consisted of 1,333 occupationally injured workers who were finished with medical treatment(693 workers returned to previous work place, and 640 workers found new work places). Main results are as follows. First, injured workers who got new jobs were vulnerable to sustainability to job, work status, average monthly wage as well as job satisfaction compared with injured workers who returned to pre-injury job. Second, gender, educational level, skill fitness, average monthly wage, welfare benefits, family income/leisure life/residential environment/social relation satisfaction, and maintenance of relation with business owner during medical care were related to job satisfaction of injured workers who returned to pre-injury job. Third, gender, work status, skill fitness, continuous work possibility, average monthly wage, family income/leisure life/social relation satisfaction, substitute worker for assigned task during medical care and maintenance of relation with business owner during medical care affected on job satisfaction of injured workers who got new jobs. Based on these findings implications for policy and interventions were discussed in regards to job satisfaction of injured workers.

This study suggests an alternative for solving quality-of-life problems of an aging workforce by seeking ways to utilize an aging workforce in corporations and society. This research empirically analyzed data from the 6th panel data of aging. Study results are as follows. First, it was confirmed that job satisfaction of aging manpower plays a mediating role in the relationship between quality of life and the job characteristics of an aging workforce. Second, it was found that the wage level of regular workers had a significant effect on job satisfaction and quality of life, and the job satisfaction of regular workers was mediated between wage level and quality of life. On the other hand, the wage level of non-regular workers did not have any effect on job satisfaction and quality of life. The results of this study suggest the necessity for companies to recognize the use of an aging workforce to improve social value. Furthermore, our results provide implications for domestic firms and government policymakers on how to use a domestic aging workforce and how to utilize regular and non-regular workers.

This study aim to examine the optimum population in Korea, which has the lowest fertility rate in the world. This study has significance because this rapid decline in the fertility rate is expected to bring the decrease of the population and unbalance in the population composition in Korea. From the social welfare perspective, the optimum population is guided by maximization of the social welfare level per person or the social welfare level in a society. The optimum population can be defined as follows: The proportion of older adults 65 and over is 15-17%, the proportion of work force is 64-69%, the index of aging is 72-104. Within the current population and population composition, the optimum population is estimated as 4.85-4.95 million. These findings imply that we need to remove causes of low fertility rate and prepare for policies encouraging immigration of labor force from foreign countries. In addition, policies and programs where children can be grown up in good environments and women and older adults can participate in labor force should be established.
