We construct a Kyle (1985)-type market model in which fast and slow traders are present. After deriving the equilibrium condition described as a simultaneous equation system, we will perform numerical calculations. A major finding is that the fast trader who has an advantage in trade frequency...

We investigate the entry timing and location decisions under market-size uncertainty with Brownian motions in a continuous-time spatial competition duopoly model a la d'Aspremont et al. (1979). Under a sequential equilibrium, the threshold of the follower non-monotonically increases in...

We investigate the decision of entry timing and product positions under market size uncertainty with Brownian motion for continuous-time spatial duopoly competition. We show the following results. First, the leader is more likely to increase the degree of product differentiation as volatility...

This study analyzes a real options model of mergers and takeovers between two firms facing different but correlated uncertainty in profits. It is assumed that firms can choose two alternatives; hostile takeover or friendly merger. In a hostile takeover, a bidder firm takes all the extra value...

We investigate quotation and transaction activities in the foreign exchange market for every week during the period of June 2007 to December 2010. A scaling relationship between the mean values of number of quotations (or number of transactions) for various currency pairs and the corresponding...

We investigate the entry timing and location decisions under market-size uncertainty with Brownian motions in a continuous-time spatial competition duopoly model a la d'Aspremont et al. (1979). Under a sequential equilibrium, the threshold of the follower non-monotonically increases in...

We advance a model of the tradable permit market and derive a pricing formula for contingent claims traded in the market in a general equilibrium framework. It is shown that prices of such contingent claims exhibit significantly different properties from those in the ordinary financial markets....

We study the investment timing problem where two firms that compete for investment preemption know in advance the time at which the economic condition changes. We show that the so-called Bad News Principle applies to the leader firm’s investment decision near maturity in many cases. This...

We consider a Markov switching regime and price a discount bond using two popular models for the short rate, the Vasicek- and CIR-dynamics. In both cases, an explicit formula is obtained for the bond price which includes the solution of a matrix ODE. Our model is easy to calculate and captures...
