Probability weighting is one of the cornerstones of decision-making theories accommodating gambling preferences. This paper examines its relevance to explaining employee stock option exercise behavior. We characterized the optimal exercise policy for a representative employee with Rank-Dependent...

This research provides an alternative framework for the analysis of employee stock option exercise patterns. It develops a binomial model where the exercise decision obeys to a policy that maximizes the expected utility to a representative employee exhibiting preferences as described by the...

This research provides an alternative framework for the valuation of standard employee stock options and for the analysis of exercise behavior patterns. It develops a binomial model where the exercise decision obeys to a policy that maximizes the expected utility to a representative employee...

Relying on conditional entropy and on the notion of information transfer, we investigate price relationships in the most important commodity futures market: the American crude oil market. We first show that the information shared by futures contracts with different delivery dates increases...

After having been considered as a public good during decades, electricity is now regarded as a tradable commodity in most developed countries. Since they were launched twenty years ago, electricity derivative markets exhibit sustained rises in their transaction volumes. Even if these markets are...

This review article describes the main contributions in the literature on term structure models of commodity prices. The first section is devoted to the theoretical analysis of the term structure. It confines itself primarily to the traditional theories of commodity prices and to their...

This article analyzes long-term dynamic hedging strategies relying on term structure models of commodity prices and proposes a new way to calibrate the models which takes into account the error associated with the hedge ratios. Different strategies, with maturities up to seven years, are tested...

We consider a multivariate financial market with transaction costs as in Kabanov. We study the problem of finding the minimal initial capital needed to hedge, without risk, European-type contingent claims. We prove that the value of this stochastic control problem is given by the cost of the...

An agent's optimization problem of the expected terminal wealth utility in a trinomial tree economy is solved. At each transaction date, the agent can trade in a riskless asset, a primitive asset subject to constant proportional transaction costs, and a contingent claim characterized by some...

The reversibility phenomenon in the repeat-sales index is a serious obstacle for derivatives products. This article provides a solution for this problem, using an informational reformulation of the RSI framework. We present first a theoretical formula (simple, easy to interpret, and easy to...
