     To encourage appropriate public opinion and public decision on public infrastructure policy, the knowledge of how the public recognizes fact information and forms recognition is important. Based on this perspective, we conducted a psychological experiment to demonstrate the presence of “Kitsch” in public opinion on public policies. “Kitsch in public policy” means an unreasonable attitude that regards a public policy including obvious dangers as a beautiful idea and denies all information that does not support the public policy. In this research, we empirically demonstrated the presence of “Kitsch” by a psychological experiment on attitudes towards supporting three policies (reduction in public works, austerity, and neoliberal reform).

     One-way car sharing is widely spread mainly in Western countries, and cities that introduce it are still increasing. Meanwhile, Autolib’, once known worldwide as a successful example of a one-way type station-based car sharing service, ended its service at the end of July 2018. In this study, we discussed the causes of service discontinuation using interviews with related parties, literature review, and analysis of open data. From the viewpoints of convenience and profitability, we will consider the optimal location of stations and the appropriate business scale when introducing a one-way station-based car sharing service in Japan, referring to the results of these analyses. Furthermore, we examine the possibility of alleviation of the uneven distribution of demand as well as vehicles by the charging policy.
