In the epoch of global business revolution, the world's leading firms have undergone a revolutionary transformation. Firms from developing countries are disadvantaged to compete on the global level playing field of international big business. This paper investigates the competitiveness of...

In the Black-Merton-Scholes framework, the price of an underlying asset is assumed to follow a pure diffusion process. No-arbitrage theory shows that the price of an option contract written on the asset can be determined by solving a linear diffusion equation with variable coefficients. Applying...

This paper presents a new algorithm to calibrate the option pricing model, i.e. the algorithm that recovers the implied local volatility function from market option prices in the optimal control framework. A unique optimal control is shown to exist. Our algorithm is well-posed. Our numerical...

Bandwidth selection is an important problem of kernel density estimation. Traditional simple and quick bandwidth selectors usually oversmooth the density estimate. Existing sophisticated selectors usually have computational difficulties and occasionally do not exist. Besides, they may not be...

We examine the impact of Regulation Fair Disclosure (RFD) on transient institutional investors' abnormal trading behavior around accounting restatements. We find that while in the pre-RFD period, transient institutional investors exhibit abnormal selling of restating firms' stocks one quarter...

In this paper, we revisit the size of stable cartels in a symmetric oligopoly model with a Cournot fringe. Konishi and Lin (1999) make a conjecture on the size of stable cartels. Due to algebra complexity, they test the conjecture by conducting numerical simulations. We provide an analytical...

In practice, managers often wish to ascertain that a particular engineering design of a production system meets their requirements. The future environment of this design is likely to differ from the environment assumed during the design. Therefore it is crucial to find out which variations in...
