Social costs analysis seeks to reveal the environmental effects of transportation policy. It delivers a sense of the effects of the public's daily travel and the costs that are or would be incurred from individual trips. Moreover, the accumulated total number of trips will uncover the effects of travel on society. This article shows the quantitative analysis of the economic outcomes of travel using social costs estimation methods. In order to support urban planning tasks, this research implemented analysis tool for social costs estimation by travel behavior. For a case study, a jave based application which can convert people's trip data into social costs is developed. the application used for simulating student-housing effects by estimating social costs changes. The analysis included the attributes, building scale and locational changes of the student housing as well as transforms of the students' trips.

The objective of this paper is to derive a optimum distance and time taxi fare structure based on social costs. Social costs expressed in terms of congestion and vehicle operating costs were successfully internalized. Speed and volume data for three major arterials in Seoul CBD were used. Optimum congestion charge turned out to be 97.01 Won/Km which can be regarded as congestion tax in the context of Seoul CBD. This congestion tax can possibly be incorporated into time-based taxi fare structure. Congestion is likely to be reduced as a result of imposition of time-based taxi fare which reflects social costs.

With the growing importance of GHG reduction, wood pellets are considered as a cheaper renewable energy and carbon neutral. On the other hand, there is a concern that the burning wood pellets may release even more air pollutants such as CO and VOCs. In this study, we analyzed the social costs of burning fuels including wood pellets and coals based on the unit calorific value. The social costs were calculated by sum of the import costs of the fuels and the emission costs of the air pollutants. The results showed that wood pellets are inferior to coals in the aspect of the social costs. It is necessary to improve the quality of the wood pellets and pellet boiler facilities for being used eco-friendly energy sources in the future. We suggest that the control facilities of CO and VOCs should be installed, if the control costs are lower than the pollution costs.

Nuclear energy issues such as safety and social acceptance can not only influence the production costs of generating nuclear power, but also the external costs that are not reflected in market prices. Consequently, the social issues affiliated with nuclear power, beyond a severe accident, require some form of financial expense. The external social issues considered here are accident risk and realization, regulatory costs, and nuclear energy policy costs. Through several calculations and analyses of these external costs for nuclear power generation, it is concluded that these costs range from 7 to 27 \/kWh. Considering external costs are required for making energy plans, it could have an influence on generation costs.

The comparison of solar energy technologies with conventional technologies involves more than just comparing the costs of supplying energy and provding capacity. Solar technologies supply energy in a sustainable manner while having minimal effects on the environment. When choosing between solar energy technologies and conventional technologies, first cost is a important factor. The environmental and other social benifits of using solar energy technologies contrasts sharply with the environmental degradation and social costs resulting from the use of conventional technologies. These hidden costs, sometimes called "social cost", are not included in conventional economics. This paper is emphasized that the consideration of social costs effects comparisons between renewable and conventional energy technologies is of importance.

The social impact of observing others' charitable donations remains underexplored, with few studies examining the influence of donors' social class. Across three experiments, we investigated how the donor social class-donation type interaction influences the observers' perceived sacrificial costs or desire for a moral self-identity, which consequently affects their willingness to donate. The participants perceived higher costs when lower-class donors made monetary donations, but for time donations, they saw no difference in sacrificial costs by donor social class. Moreover, when the hourly wage was emphasized, the participants felt an increased desire for a moral self-identity from higher-class donors' monetary donations and became more willing to donate their money. These findings highlight the importance of considering both the donor social class and donation type when designing donation campaigns, and offer valuable insights for enhancing overall donation amounts.

The aim of this study is to assess the impacts of service properties, price expectancy, social influences, and switching costs on adoption intention of 4G in Vietnam. The research model was established by the theory of diffusion of innovation, technology acceptance model, service quality, social influences and switching costs. The result from customers using telecommunication services in Vietnam shows that adoption intention of 4G is affected directly by perceived usefulness, personal innovativeness, price expectancy, social influences, prior service quality and switching costs. Whereas, switching costs have negative effect on adoption intention. Other factors such as personal innovativeness, perceived ease of use and prior service quality have an indirect effect on adoption intention of 4G.

In this study, we developed a method to quantify urban social costs using mobile sensing data, providing a novel approach to urban planning. By collecting and analyzing extensive mobile data over time, we transformed travel patterns into measurable social costs. Our findings highlight the effectiveness of big data in urban planning, revealing key correlations between transportation modes and their associated social costs. This research not only advances the use of mobile data in urban planning but also suggests new directions for future studies to enhance data collection and analysis methods.

교량구조물은 사회물류흐름에 필요한 중요한 역할을 하는 사회간접시설물로 공용수명이 다하거나 지진, 폭풍 등의 자연재해에 따라 구조물의 손상이 발생할 경우 기존 교량을 철거하고 재가설 하여야 한다. 공용중인 교량을 재가설할 경우, 차량의 우회, 교통체증에 따른 사용자비용과 공사기간동안의 소음, 분진 등에 따른 사회비용이 발생하게 된다. 하지만 교량의 재가설에 따른 사용자비용과 사회비용은 교량건설시 고려되지 않고, 이를 평가하는 방법 또한 모호하므로 이를 적용한 교량형식이 선정되지 못하고 있다. 따라서 본 연구에서는 교량의 재가설시 발생되는 사회적 간접비용, 즉 사용자의 사회적, 경제적 가치를 파악하여 교량 재가설에 따른 사용자비용의 평가방법을 제안하고 이를 평가하였다. 사용자비용의 평가 시 교량의 일교통량, 첨두시간, 우회거리, 우회시간 등을 포함한 교통정보와 사회적 물동량이 고려되었으며, 차량운행비용과 교량 재가설에 따른 시간지연비용 또한 고려되었다.

A considerable cost gap between three major power generation technologies, namely nuclear, coal, and combined cycle gas turbine (CCGT), has been a well-established fact in the Korean electricity market. Alternatively, this paper analyzes the levelized costs of electricity (LCOE) of the three technologies reflecting overall social costs of electricity generation including accident risk, $CO_2$ emission, and air pollution damage. The paper unveils to what extent current discriminative subsidies on fuels regarding the social costs, mostly through tax exemptions, affect economic competitiveness of the technologies. In particular, it finds relative positions of coal and CCGT could be altered depending on appreciation level of the social costs. It has limits in analyzing fixed costs of the technologies, however, due to limited data availability of nuclear power, and suggests further studies on the issue.
