A super-replication theorem in Kabanov’s model of transaction costs

Campi, Luciano; Schachermayer, Walter - Université Paris-Dauphine (Paris IX) - 2006

We prove a general version of the super-replication theorem, which applies to Kabanov’s model of foreign exchange markets under proportional transaction costs. The market is described by a matrix-valued càdlàg bid-ask process $$(\Pi_t)_{t\in [0,T]}$$ evolving in continuous time. We propose a...

Information Flows in the term structure of commodity prices

Lautier, Delphine; Raynaud, Franck - Université Paris-Dauphine (Paris IX) - 2014

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...
