 Le contrat notionnel: efficience et causalitBernard Bensaid () and Michel Boutillier Working papers from Banque de France Abstract: The main topic of this paper is about the overall functionnning of the french futures bonds market. Three mains questions are asked: (1) Is the futures market inefficient? (2) Is there any free lunch between the future market and the spot market? (3) Does one of these markets play a leader role? Econometric tests give globally an negative answer to all these three questions. The arbitrage's opportunities which have been detected in the period 86.12-90.06 can be explained by the restrictions to sell-short bonds in the french cash market. The two tests on the rationality of the expectations which have been undertaken (a time series test and a panel data test) yield the same conclusion : one cannot reject the assumption that the market is efficient. Finally, tests of causality between the future market and the cash market on daily data shows strong instantaneous correlation between them. Concerning delayed causality, the future market have played a leader role during the period 90.01-93.06 during which one has observed an overall stability of the futures prices.
