This paper empirically studied the model-free implied volatility indices constructed from options prices of the Nikkei 225 index during 2005-2010. The concept of corridor volatility index is compared and contrasted with the methodology of the famous VIX index developed by the Chicago Board...

In this article, we consider a derivative pricing model for the stochastic volatility model under an incomplete information. The incomplete information in our works, supposes that the true value of the drift for the stock price process is a random variable, investors only have an information of...

This paper examines how the informational efficiency of the Japanese stock markets changed with the introduction of ETFs(Exchange-Traded Funds) by looking at the arbitrage relationships between cash and futures of the Nikkei225. This paper is unique in that it uses tick data, which enable me to...

In this paper we analyze return and volatility spillovers during overlapping trading hours between China (Shanghai Composite Index) and Japan (Nikkei 225 Index) using intraday high-frequency data. We first adjusted the 5-min. returns for intraday periodicity with Flexible Fourier Form (FFF)....

We analyze the mechanism of return and volatility spillover effects from the Chinese to the Japanese stock market. We construct a stock price index comprised of those companies that have substantial operations in China. This China-related index responds to changes in the Shanghai Composite Index...

In this paper, we deal with no-arbitrage pricing problems of a chooser flexible cap (floor) written on an underlying LIBOR. The chooser flexible cap (floor) allows a right for a buyer to exercise a limited and pre-determined number of the interim period caplets (floorlets) in a multiple-period...

I investigate the decision-making process of an owner of abandoned farmland that is currently restricted to agricultural use but will be available for nonagricultural use in the future. I find that a slight probability of land conversion greatly increases the land value and discourages the owner...

We develop a dynamic model in which a firm exercises an option to expand production with cash balance and costly external funds. While related papers explain their results only by numerical examples, we analytically prove the following results. In the presence of only a proportional cost of...

This paper investigates a principal-agent model in which an owner (principal) optimizes a contract with a manager (agent) delegated to undertake an investment project. In the model, we explore the effects of costly exploration by which the manager learns the real value of development cost. We...

We develop a model for determining whether a firm should exercise two real options individually or simultaneously. The simultaneous exercise of both options has positive synergy, such as economies of scale, scope, and networks, while separate exercise of each option benefits from project...
