This paper studies a classical extension of the Black and Scholes model of option pricing, often known as the Hull and White model. Our specificity is that the volatility process is assumed not only to be stochastic, but also to have long memory features and properties. We study here the...

This paper, prepared for the Invited Symposium "Financial Econometrics" at the 7th WCES, Tokyo, August 1995, surveys the subject of Econometrics of option pricing, and more precisely try to offer versatile tools to model the source of the prediction errors in option pricing.

This paper compares the performance of Black-Scholes with an artificial neural network (ANN) in pricing European style call options on the FTSE 100 index. It is the first to study the performance of ANNs in pricing UK options, and the first to allow for dividends in the closed-form model and the...

les actions a bons de souscription d'actions directes (sans droit preferentiel de souscription) sont systematiquement sous-avaluees lors de leur emission en France. Nous proposons une explication de ce comportement des societes fondee sur l'arbitrage entre perte du droit preferentiel pour les...

What kind of information do stock prices offer for predicting velocity? This paper develops previous work by Milton Friedman for the US economy and shows that a wealth effect derived from the stock market has negatively influenced the ratio of nominal income to a broad definition of money in a...

This paper introduces nonlinear dynamic factor models for various applications related to risk analysis. Traditional factor models represent the dynamics of processes driven by movements of latent variables, called the factors. Our approach extends this setup by introducing factors defined as...

This note provides a simple proof of the necessity of the transversality condition for the differentiable reduced-form model. The proof uses only an elementary perturbation argument without relying on dynamic programming. The proof makes it clear that, contrary to common belief, the necessity of...

This paper establishes (i) an extension of Michel's (1990, Theorem 1) necessity result to an abstract reduced-form model, (ii) a generalization of the results of Weitzman (1973) and Ekeland and Scheinkman (1986), and (iii) a new result that is useful particularly in the case of homogeneous...

Models use for natural resources prices usually preclude the possibility of large changes (jumps) resulting from discrete, unexpected events. To test for the presence of jumps and ARCH effects, we propose to use bounds and bootstrap test techniques, thus solving the unidentified nuisance...

The returns from international investment involve returns from not only the asset, but also the return from the exchange rate fluctuations. This means that investors from different countries have the potential to earn different returns from the same investment strategy. The change of numeraire...
