A study of the Institute Research Lab, the oil would have increased their margins in 20 years, by not passing on enough cuts in crude oil prices at the pump.
The alarm is again drawn. A report by the Institute Research Lab, which has obtained the daily Le Parisien, points to the tendency of oil does not affect the pump lower crude prices.
May 30, a similar report was made by the Fraud Christine Lagarde. The former economy minister was then immediately wanted to force oil companies to pass on lower oil prices on fuel prices. But "the work of the DGCCRF covered only two week period," says Thomas Porcher, who led the new study.A period far too short, then, to realize if there was or not, a real impact of lower crude prices at the pump …
Loss of purchasing power for consumers
But this time, the study of the Institute Research Lab examined a time much longer – in this case 20 years – from 1990 to April 2011. It appears, according to Thomas Porcher, the fit between crude prices and those at the pump "is lower in the case of a decrease in that of a rise in crude prices." Thus, when there was a 1% increase in crude oil prices, prices at the pump would increase during the week of 0.12%. However, in the case of a 1% decrease, they decrease only 0.07%.
These figures therefore tend to prove that the oil benefit of lower oil prices to achieve margins.The report denounces "an asymmetry in the response of fuel prices, resulting in a loss of purchasing power for consumers."
