An experimental approach to the effectiveness of an incentive system against moral hazard in the insurance market

Although traditional Japanese insurance theory has tended to assume the basic altruism of policyholders, this assumption may not be warranted. Many people might be opportunists rather than altruists. So in the actual insurance market, moral hazard may occur not accidentally but naturally. Without effective incentive mechanisms, policyholders may deviate from their original purpose. It is important to design penalties as negative incentives for the control and prevention of moral hazard. We test these propositions here by means of a game theory and questionnaire. The reason why we use a game theory and carry out the questionnaire is that it is not suitable to apply the econometric model to collect reliable data about moral hazard.     

Times and Spaces of Homeless Regulation in Japan, 1950s–2000s: Historical and Contemporary Analysis

Since the late 1970s, Atlantic Fordism has seen rising homelessness and ghettoization as the ‘new urban poverty’ (NUP) (Mingione, 1996). Despite some similarities, the NUP in Japan has a unique rhythm and spatial pattern. In order to explore Japanese NUP, this article develops an interpretation of Japan's strategies to regulate poverty and homelessness during the last 50 years, paying particular attention to the spatial consequences of such strategies within major Japanese cities. First, I theorize long‐term economic growth patterns as a basic parameter of poverty and homelessness regulation and present a periodization of Japanese trends since the 1950s. Second, I analyze poverty in Japan and the transformation of national strategies of spatial regulation in the 1990s, when homelessness grew. Third, I examine the multi‐scalar processes through which new regulatory spaces of homelessness were produced in the 1990s and 2000s, when failures of post‐bubble crisis management ballooned in Japan. I argue that, through a dialectic between national/local rule‐setting and homelessness, the Japanese state fragmented the dominant scale of poverty regulation, rescaled the site of homeless regulation and contained homelessness in relatively autonomized cities. I conclude that, from the 1990s until the late 2000s, Japan's homelessness and its contradictions tended to be transferred to the spheres of urban workfare and urban policing, which I call new regulatory spaces of homelessness, that lie around the fringes of national social rights.
