We analyze the physical, i.e. non financial, determinants of the real price of crude oil by means of an equilibrium correction model over the last two decades. We find that two cointegrating relations affect the change in prices: one refers to OPEC's cartel behavior attempting to control prices...

This paper proposes a Near Explosive Random-Coefficient autoregressive model for asset pricing which accommodates both the fundamental asset value and the recurrent presence of autonomous deviations or bubbles. Such a process can be stationary with or without fat tails, unit-root nonstationary...

This paper considers approximating the nite sample null-distribution of a test statistic as its asymptotic distribution under a local alternative. We focus on the Likelihood Ratio test for the rank of cointegration and use nonlinearities that represent some nite sample distributional features....

Standard tests for the rank of cointegration of a vector autoregressive process present distributions that are affected by the presence of deterministic trends. We consider the recent approach of Demetrescu, Lütkepohl and Saikkonen (2009) who recommend testing a composite null. We assess this...

Avec le desserrement de certaines contraintes extérieures — notamment celles liées à l’appréciation passée de l’euro et à la forte augmentation du prix du pétrole —, l’économie française devrait croître en moyenne annuelle de 2,2 % en 2006 et de 2,1 % en 2007. Ce rebond de...

Le tourisme est un secteur d’importance dans l’économie française. En 2004, la production de services de tourisme en France a été de 106 milliards d’euro soit plus de 6.5 points de PIB (Direction du tourisme, comptes du tourisme). Ce secteur emploie directement plus de 800 000...
