I show the equivalence between a model of financial contagion and the widely-used threshold model of global cascades proposed by Watts (2002). The model financial network comprises banks that hold risky external assets as well as interbank assets. It turns out that there is no need to construct...

The question of how to stabilize financial systems has attracted considerable attention since the global financial crisis of 2007-2009. Recently, Beal et al. (gIndividual versus systemic risk and the regulator's dilemmah, Proc Natl Acad Sci USA 108: 12647-12652, 2011) demonstrated that higher...

This study applies a threshold model proposed by Granovetter (1978) to analyze the dynamic diffusion process of donating behavior for renewable energy. Using data on people's willingness to donate for renewable energy under various predicted participation rates, we simulate how herd behavior...

We attempt to examine the extent to which poverty in childhood adversely affects success in adulthood, using micro data from nationwide surveys in Japan and taking into account the recursive structure of life outcomes. We use retrospective assessments of income class at the age of 15, because...

Evidence on the effect of the social security earnings test on the labor supply of the elderly continues to be mixed. We utilize microlevel data compiled by the Japanese government in order to examine the labor supply effect for those aged 6569 before and after two majo reforms of the social...

We examine how Japanese parents evaluate the current education system and assess possible reforms, based on a nationwide parent survey. Parents who have higher educational background, occupational status, and household income, and expect higher education attainment from their children tend to be...

This study examines the expectational stability of the rational expectations equilibria (REE) under alternative Taylor rules when trend inflation is non-zero. We find that when trend inflation is high, the REE is likely to be expectationally unstable. This result holds true regardless of the...

We investigated attributes of tourists in Oz National Park, their schedules, experiences of utilization of professional guidance, and preferences for the tour with professional guidance by conducting in-person survey in order to promote effectively. We suggest that it is prerequisite for...
