The U.S. agency mortgage backed securities (MBS) market is deep and highly liquid, yet modeling MBS is extremely challenging. This paper applies market participants' desired requirements for a good pricing model to MBS pricing models provided by six of the top MBS dealers. We find that five out...

Option prices vary with not only the underlying asset price, but also volatilities and higher moments. In this paper, we use a portfolio of options to seclude the value change of the portfolio from the impact of volatility and higher moments. We apply this portfolio approach to the price...

Five U.S. exchanges compete to provide quotes and attract order flows on common set of stock options: the American Stock Exchange, the Chicago Board of Options Exchange, the International Securities Exchange, the Pacific Stock Exchange, and the Philadelphia Stock Exchange. In this paper, we...

With the increasing availability of supply chain information, researchers are paying increasing attention to information flows and interactions between suppliers and customers. This paper examines the interactions from the perspective of an economy-wide supply-chain network, and propose a list...

In this paper we extend the model of Easley and O'Hara (1992) to allow the arrival rates of informed and uninformed trades to be time-varying and forecastable. We specify a generalized autoregressive bivariate process for the arrival rates of informed and uninformed trades and estimate the model...

With increasing appreciation of the fact that stock return variance is stochastic and variance risk is heavily priced, the industry has created a series of variance derivative products to span variance risk. The variance swap contract is the most actively traded of these products. It pays at...

The challenge of international term structure models is to simultaneously account for the properties of interest rate term structures and foreign exchange rates within an arbitrage-free framework. We extend the quadratic term structure models proposed in Leippold and Wu (2002) to multiple...

Most existing hedging theories are derived under strong, idealistic assumptions on both the underlying security price dynamics and the trading environments. Practical concerns such as contract availability, transaction cost, and uncertainty regarding the security price dynamics impose severe...

Economic theory suggests that the magnitude and direction of a company's currency risk exposure depends crucially on its fundamental involvement in international trade. For U.S. industries, we find that the stock performance of import-oriented companies moves positively with the performance of...
