This paper presents an overview of information-based asset pricing. In the information-based approach, an asset is defined by its cash-flow structure. The market is assumed to have access to “partial” information about future cash flows. Each cash flow is determined by a collection of independent market factors called X-factors. The market filtration is generated by a set of information process...

URL: www.thejournalofcomputationalfinance.com This paper develops formulas for pricing caps and swaptions in Libor market models with jumps. The arbitrage-free dynamics of this class of models were characterized in Glasserman and Kou (2003) in a framework allowing for very general jump processes. For computational purposes, it is convenient to model jump times as Poisson processes; however, the...

B2B e-marketplaces drastically alter the structure of buyer-seller relationships. To study the equilibrium of a buyer-seller exchange network before and after the emergence of emarketplaces, we develop a multiple-person noncooperative game, where rational firms select optimal interfirm connections and the network is endogenously formed and evolved. We examine when previous buyer-seller relation...

A market maker sets prices over time for wagers that pay out contingent on the future state of the world. The market maker has knowledge of the probability of realizing each state of the world, and of how the price of a bet affects the probability that traders will accept it. We compare the optimal policy for risk-neutral (expected utility maximizing) and Kelly criterion (expected log-utility m...

AIDs demand models are used to test if the generic promotion of fresh-cut flowersinfluenced the market shares for florists, supermarkets, and other retail outlets. Were thegeneric efforts outlet neutral? Generic promotions of fresh-cut flowers is shown to be outletneutral while the brand advertising increased florists’ market share.

We investigate the pricing of risk-neutral skewness in the stock options market by creating skewness assets comprised of two option positions (one long and one short) and a position in the underlying stock. The assets are created such that exposure to changes in the underlying stock price (delta) and exposure to changes in implied volatility (vega) are removed, isolating the effect of skewness....

We study a dynamic model of asset pricing which is driven by two characteristic market features: the law of investor demand (e.g. ’buy low, sell high’) and the law of the market institution (which codifies the trading rules under which the market operates). We demonstrate in a simple investor-specialist trading market that these features are sufficient to guarantee an equilibrium where investor...
