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...

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...

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...

This paper studies the impact of financial inclusion on wealth accumulation. Exploiting the US interstate branching deregulation between 1994 and 2005, we find that an exogenous expansion of bank branches increases low-income household financial inclusion. We then show that financial inclusion...

We study horizontal partial acquisitions in an oligopolistic industry in the absence of synergies. Contrary to existing results, we find that a dominant shareholder may choose to acquire shares in a competitor although the aggregate profit of the group of firms under his control, and even the...

Les modifications de l’environnement économique constituent pour les entreprises des incitations à modifier leurs prix. On observe toutefois que l’ampleur de ces révisions est assez modérée et que près d’une fois sur deux, ces révisions consistent en une baisse de prix.

Dans cet article nous nous proposons d'analyser les effets de l'ouverture à la concurrence sur les stratégies de tarification des ventes liées à travers un modèle de choix discret. Nous montrons que dans une situation de duopole vendre les biens de manière indépendante est un équilibre...
