In this paper, we consider American option contracts when the underlying asset has stochastic dividends and stochastic volatility. We provide a full discussion of the theoretical foundations of American option valuation and exercise boundaries. We show how they depend on the various sources of...

Prior work on option pricing falls mostly in two categories: it either relies on strong distributional or economical assumptions, or it tries to mimic the Black-Scholes formula through statistical models, trained to fit today's market price based on information available today. The work...

Characterizing asset return dynamics using volatility models is an important part of empirical finance. The existing literature favors some rather complex volatility specifications whose relative performance is usually assessed through their likelihood based on a time-series of asset returns....

In this paper, we characterize the asymmetries of the smile through multiple leverage effects in a stochastic dynamic asset pricing framework. The dependence between price movements and future volatility is introduced through a set of latent state variables. These latent variables can capture...

This paper aims at explaining observed distinct prices announced by a single supplier for an identical product, in an illegal framework. The modeling proposed here examines an augmented mark-up pricing equation for oligopolistic markets that includes a function of social discrimination. The...

In this paper, we analyze the incentives for improving-quality R&D in a two-tier marketstructure where the quality of a differentiated good depends on the specific R&D of a downstream oligopoly and the R&D of an upstream monopoly. We show that input pricing is determining for the incentives for...
