This paper proposes a new three-factor model with stochastic mean reversions for commodity prices and derives the closed-form solution for the term structure of futures prices. It also examines the relation of our model with Schwartz(1997) type models that explicitly include interest rates and...

This paper proposes a structural model to price credit risk of firms with short-term and long-term debts. This enables one to distinguish between default probabilities in the short run and in the long run, and to identify how the composition of debts affects credit risk. We endogenize the banks'...

We developed a variance reduction method of Monte Carlo simulations as well as an approximation formula based on an asymptotic expansion approach for pricing bond options and swaptions in HJM framework. As a numerical example we applied the technique to a realistic two-factor model and confirmed...

This paper investigates the value relevance of accounting earnings, with testing empirically the association between stock price levels and earnings of manufacturing firms in Japan. This research provides major five results as follows. First, whether to deflate the variables included in the...

In this paper, we examine the influences of the Showa Financial Crisis on Mitsubishi Bank, one of the largest banks in prewar Japan, using its daily financial data. It is known that the Crisis gave contrasting effects on the major banks and the other ones. Large amount of deposits moved from the...

Recent surge of large real estate lending in Japan suggests the creation of a new series of lumpy credit risk exposures entering Japanese bank portfolios. It is necessary to transform these types of large, concentrated exposures into more manageable pieces of risk. The development of syndication...

We examine a dictator game with a "voice" option in the laboratory. In the dictator game, player 1 dictates how to divide a pie, and player 2 simply receives his/her share, i.e., unlike in an ultimatum game, he/she does not have an option to reject this division. In our experiment, player 2 has...

We summarize the recent developments on the statistical method of Lasso-Quantile Regression and we apply it to a Non-life Insurance problem. We discuss the asymptotic properties of the Quantile Regression estimator, the computational aspects related to the Linear Programming problem and the...
