We investigate jump memory using an extensive database of short-term S&P 500 index options. Jump memory refers to the attenuation of the implied jump intensity and magnitude parameters following a crash event. We use a genetic algorithm to obtain a time series of implied parameter estimates and...

A real option on a commodity is valued using an implied binomial tree (IBT) calibrated using commodity futures options prices. Estimating an IBT in the absence of spot options (the norm for commodities) allows real option models to be calibrated for the first time to market‐implied probability...

This paper provides a non-technical presentation of the theoretical foundations of corporate financial decision making and the net present value (NPV) rule. Our objective is to show that the concepts of value and value creation arise from a single, unified framework that is firmly rooted in...

An increase in the cost of selling short should increase the bearish information content of short interest announcements by driving relatively uninformed short sellers out of the market. We extend the Diamond and Verrecchia (1987) model to include short selling against the box and test the...

Which journal articles have had the most impact on finance research? Which journals dominated finance research in the 1990s? We answer these and similar questions using a comprehensive sample of journals, an extensive time period, and a new ranking method that avoids problems inherent in the...

This paper develops visual aids for the understanding of two asset portfolio mathematics. Specifically, visual aids are utilized in teaching portfolio variance and correlation coefficient concepts. The presentation is simple, yet powerful, and is useful for an audience with varying levels of...
