This study primarily analyzed the use of shipping companies' welfare program by the characteristics of crew's demography and working condition on board, and next examined the effect of the satisfaction to the program on the organizational commitment and job satisfaction to the companies, in order to survey the shipping companies' welfare reality which has performed an influential role to meet the various welfare needs of personal crew. According to the findings in the recent survey of 459 seamen on board, there are differences among the use of the program by crew's the tolerance to work on board and personal characteristics, for example, age, marriage, position, period on board, and years of service. Moreover, the study verified the fact that the higher satisfaction to the use of those program, the higher organizational commitment and job satisfaction of crew.

This study investigates the welfare implications of BTL projects using a general equilibrium model with the public sector and public-private partnerships. We show that when the government is not allowed to run budget deficits but private firms is able to overcome the financial constraint, BTL projects performed by public-private partnerships (PPPs) could be a good alternative and improve the welfare of the model economy. This paper quantitatively investigates excessive expansion of PPP projects and several alternatives to retrieve welfare losses caused by such an expansion. Assuming that future rents of BTL projects are not taken into account, we find the welfare losses up to 20 percent relative to conventional government projects. Finally, we show that it would be possible to reduce the losses by transforming the fully depreciated capital stock of the government projects into much smaller new PPP projects.

So far, land use-transportation models have been used exclusively for numerical analysis. A recent theoretical endeavor now enables us to derive the first-order derivative of the model's welfare function with respect to policy variables. I extend this methodology into the institutional setting where toll revenues are recycled through labor income tax. In this setting, the first-order derivative is composed of (1) the increase in welfare due to reduced congestion, and (2) the decrease in welfare due to interaction with the existing labor income tax. This result coincides with existing theory in the non-spatial model.

This study analyzes the economic effects of reduction of green-belt. Green-belt is a kind of land which is restricted to be developed into housings. It is important for social welfare. It affects the social welfare by two routes. One way is through the housing market process. Development of green-belt into housings increases housing supplies and lowers rents. The other is that it improves the living condition by increasing green spaces. Therefore, the development of green-belt to housing can Improve or worsen the social welfare. This paper analyzes its welfare effects by simulations. The results of the paper show that reduction of green-belt increases housing supply and lowers the rent and asset prices. The social welfare is improved in the model.

웹2.0이라는 개념과 트랜드는, 개방성, 사용자 참여, 집단 지성, 인간중심의 IT 서비스 등을 키워드로 하는, 플랫폼 기반 비즈니스 모델을 통칭한다. 전세계적 블로그 열풍이나, Googlization으로 불리기도하는 주요 웹포탈의 성장은 이러한 현상을 뒷받침하는 증거이며, 미래 인터넷 시장을 개척하는 엔진으로 자리잡고 있다. 그런데 웹2.0을 기술적으로(descriptive) 소개하거나 관련된 요소기술에 대한 문헌은 많음에도 불구하고, 이러한 현상을 경영/경제학적 시각에서 체계적으로 분석한 연구는 의외로 많지 않다. 본 논문에서는 기존의 웹(웹1.0)과 웹2.0 서비스 모형을 경영 경제학적 관점에서 구조화하고, 이들 서비스 모형을 Stakelberg 게임의 관점에서 분석한다. 특히 본 연구에서는 웹2.0의 다양한 국면 중에서 프로슈밍(prosuming)에 초점을 맞춘다. 분석 결과, 웹2.0에서 사용자 후생이 웹1.0에 비해 크게 증가한다는 것을 확인할 수 있었다. 또한 사용자 스스로 맞춤화된 정보를 창출하는 노력과 한계편익간의 비율을 나타내는 ${\delta}_c$('고객화 요소'로 부름) 분포의 범위(파라미터 ${\delta}$)가 사회후생에 중요한 역할을 함을 발견하였다. 이는 고객화 요구의 다양성이 커짐에 따라 사용자 후생을 비롯한 사회후생도 증진됨을 의미한다.

The purposes of the paper are to estimate welfare change from water quality degradation by using contingent valuation method in Namdae stream of Gangrung and identify what factors of Namdae stream are important to Gangrun citizens. The study results show their total WTP per year and per household, \117,040 to improve Namdae stream quality from grade 3 to grade 1, including monetary WTP \87,502 plus opportunity cost of volunteering time for protection campaign, \29,538. The amount of total welfare change from water quality degradation based on the total WTP estimated above is calculated to be \27 billion of which the amount, as a sort of damage cost from water quality degraded, is so huge. All projects and policies related to natural environments, therefore, should consider both indirect and direct effects from them because natural environments have the irreversibility once degraded or deteriorated and would ultimately be influential on humans, both current and future generations, with tremendous amounts of time and costs beyond our imagination.

I examine the situation in which the players compete to obtain economic rents which is generated by the market-based environmental regulation, such as carbon taxes or tradable permit allocations. Drawing on contest theory, I employ the sharing rules which is devised to motivate players best effort, and consider two models in carbon taxes: one model with observable sharing rules and the other model with unobservable sharing rules. I show that, first, the overall welfare of carbon taxes is always less than that of tradable permit allocations under the model with observable sharing rules. Second, depending on the share of the preassigned allocation in tradable permit allocations, the overall welfare of carbon taxes may be larger than that of tradable permit allocations under the model with unobservable sharing rules.

The purpose of this research is to establish the effects of the welfare benefits for security agents on the organizational commitment and the job satisfaction. To achieve this purpose, data were collected from 288 security agents of the security companies located in Seoul and Gyeonggi regions using the welfare benefit, organizational commitment, and job satisfaction scale, and the collected data were analyzed using SPSS 18.0 and AMOS 18.0. The conclusion obtained from the results of the analysis is as follows : First, it was the difference in welfare benefits, organizational commitment, job satisfaction, depending on individual characteristics of the security agents. Second, it was found that the cultural support, facilities support, economic support, and life support of welfare benefits had positive effects on the organizational commitment of security agents, and the conclusion that the welfare benefit factors are important to increase the organizational commitment was derived. Third, it was found that the cultural support, facilities support, economic support, and life support of welfare benefits had positive effects on the job satisfaction of security agents, and the conclusion that satisfying the welfare benefits is a way to raise the job satisfaction was derived.

This study is an empirical analysis of the welfare of small and medium venture company trade. In the past, although the study analyzes the trade welfare for representative firm, this research is focusing on the distribution of an entire industry of companies analyzed. In this study, medium-to venture enterprise-scale for logarithmic normal distribution and Pareto distribution is estimated, and this study investigates the trading welfare changes. Results of the analysis can be summarized as follows. First of all, greater trade benefits enterprise-scale heterogeneity appeared to be significant. The result of this finding appeared to be the same to large firms as well as small and medium ventures. Trading welfare, assuming the distribution of Pareto rather than logarithmic normal distribution it's supposed to be overwhelmingly large. Secondly, the case of large corporations shows the more trade welfare than that of small and medium venture companies. Third, assuming homogeneous distribution of enterprise-scale trade welfare differences did not exist. Finally, from the point of view of increasing the welfare of trade, the diversity aiming of venture business is a very important role in the long term, because of the small and medium-sized ventures trade role.
