An essential element of any realistic investment portfolio selection is the consideration of transaction costs. Our purpose, in this paper, is to determine the maximum return and the corresponding number of securities to buy giving such return, whenever practical constraints features related to...

In this paper we study the development of the market for weather derivatives in Europe. We show that weather derivatives conceived as financial products by their promoters have difficulties finding end-users. We describe the attempts of market promoters using a framework drawn from economic...

One of the central questions in corporate finance is whether investors prefer to receive their payouts from corporations in the form of cash dividends or as capital gains. We know that most firms pay dividends, even though doing so is costly in various ways. And we know that the market reaction...

We propose a simple model which embeds cost allocation games into a richer structure to take into account that information on costs can be itself costly. The model is an outgrowth of experience on cost allocation for consortia of municipalities dealing with garbage collection.

This paper posits itself in the stream of literature related to event studies and in particular the September 11th event. It is the first study to our knowledge that investigates the impact on the French financial market of September 11th, 2001 and September 21st, 2001. Was there any information...

Local volatility models are popular because they can be simply calibrated to the market of European options. We extend the results of [4], [3] for such models, i.e. we propose a modi ed Leland method which allows us to approximately replicate a European contingent claim when the market is under...

Inspired by the theory of financial markets with transaction costs, we study a concept of essential supremum in the framework where a random partial order in View the MathML source is lifted to the space View the MathML source of d-dimensional random variables. In contrast to the classical...

We study the Leland model for hedging portfolios in the presence of a constant proportional transaction costs coefficient. The modi fied Leland's strategy defi ned in [2], contrarily to the classical one, ensures the asymptotic replication of a large class of payoff . In this setting, we prove a...
