Previous studies have suggested that some pollutant levels first increases due to the economic growth and then start decreasing, the pattern being called the "environmental Kuznets curve" (EKC). We examine EKC-type transitions of pollutant levels not with respect to economic growth but more...

This paper extends the one-factor Gaussian copula model, the standard market model for valuing CDOs, based on the multivariate Wang transform. Unlike the existing models, our model calibrates the parameter associated with a risk adjustment for default threshold, not correlation parameter, which...

In recent years, it has become common to use a Markov chain model to describe the dynamics of a firm's credit rating as an indicator of the likelihood of default. Such a model can be used not only for describing the dynamics but also for valuing risky discount bonds. The aim of this paper is to...

The Black-Scholes option price is increasing and convex with respect to the initial stock price. increasing with respect to volatility and instantaneous interest rate, and decreasing and convex with respect to the strike price. These results have been extended in various directions. In...

This paper proposes a new pricing model for corporate securities issued by a levered firm with the possibility of debt renegotiation. We take the structural approach that the firm's earnings follow a geometric Brownian motion with stochastic collaterals. While equity holders can default the firm...

This paper proposes a Markov chain model for studying the impact on asset prices of illiquidity associated with search and bargaining in an economy. The economy consists of finitely many agents who can trade only when they find each other, and any trade between agents changes the population of...

With the introduction of the international accounting standards in Europe and dissemination of LDI (Liability Driven Investment) as a new investment standard, the investor demand for super-long end has been rising also in Japan. Under these circumstances, it is required that the Japanese...

This book consists of 11 papers based on research presented at the KIER-TMU International Workshop on Financial Engineering, held in Tokyo in 2009. The Workshop, organised by Kyoto University's Institute of Economic Research (KIER) and Tokyo Metropolitan University (TMU), is the successor to the...

This paper examines the impact of international debt shifting and exchange rate uncertainty on investment and capital structure decisions of foreign subsidiary. We find that debt shifting induces earlier investment, earlier default, higher leverage, and larger ex ante firm value of foreign...

This paper examines the B¨uhlmann’s equilibrium pricing model (1980) in the presence of transaction cost and derives the (multivariate) Esscher transform within the framework under some assumptions. The result reveals that the Esscher transform is an appropriate probability transform for the...
