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...

This paper investigates how investors evaluate a membership of sustainability index. By using the data on the Morningstar Socially Responsible Investment Index from 2003 to 2010, we estimate the impact of inclusion on and exclusion from the Index on the stock price. Result shows that the...

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 investigates potential demand for infrastructure investment for alternative fuel vehicles (AFVs) by using a stated preference survey of 1,531 Japanese citizens. The potential demand is estimated on the basis of how much people are willing to pay for AFVs under different refueling...

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...

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...
