In this study, the effect of the reinforcement on the wear behavior of hypereutectic Al–Si composites was investigated by performing a ball-on-disk test. The specimens were manufactured by hot press after gas atomizing. Al–20Si–5TiC composite exhibited superior wear resistance than other...

Cochrane and Sa'a-Requejo (2000, Journal of Political Economy) proposed the good-deal price bounds for the European call option on an event that is not a traded asset, but is correlated with a traded asset that can be used as an approximate hedge. One remarkable feature of their model is that...

We investigate full prepayments of Japanese residential mortgages during a ten-year period from 1996 to 2005. This investigation is important because the amount of mortgages outstanding in Japan is huge, yet the study on their prepayments is very limited. This period from 1996 to 2005 was...

We will generalize the Black-Scholes option pricing formula by incorporating stochastic interest rates. Although the existing literature has obtained some formulae for stock options under stochastic interest rates, the closed-form solutions have been known only under the Gaussian (Merton type)...

An endogenous growth model with heterogeneous agents is analyzed to show that “human capital flight” or “brain drain” can lead to a permanent reduction in income and growth of the country of emigration relative to the country of immigration. Convergence between the two is therefore...

This paper presents a framework for quantitatively evaluating the macroeconomic effects of corporate restructuring and applies that framework to Japan. Using firm-level financial statement data, this paper estimates total factor productivity of individual Japanese firms. Given the estimated...

The technological constraints on sustaining production chains have been discussed extensively by development economists, but the role of financial linkages has received less attention. In a model of recursive moral hazard for a manufacturing supply chain, we show that the structure of...
