kmann gave us the following little computation the other day from the time period around the hurricanes last year. The data is for Unleaded Gas, and I think it is quite good:
$this->bbcode_second_pass_quote('', 'C')hange in demand before price increase: + 2.3 % (yoy, 4 week ave.)
Change demand after price increase: -2.5 % (yoy, 4 week ave.)
Difference of change in demand: -4.8%
Price before hurricane: 2.29 (4 week ave.)
Price after hurricane: 2.83 (4 week ave.)
Change in price: 0.54 per gal
1 % decrease in demand per 0.11 increase in price
8.9 % decrease in demand per 1.00 increase in price
So at 42 gallons of gasoline/distillates per barrel of oil, maybe a $42 per barrel price increase in crude oil would give you the same effect. An 8.9% cutback by American drivers would represent maybe 1-2% off of the global crude oil consumption. Maybe that is, and maybe that is not enough to cause the price to drop, since China seems capable of buying all of the oil that we do not use.
Other questions:
How permanent would such a price increase have to be in order to cause a permanent cutback in driving? Obviously the hurricane-induced cutback was not permanent or large enough to cause a permanent change.
Once the driving cutback occurred, how long before the effects would be felt in areas like the automotive industry and other related parts of the economy?
Is the calculation linear, or is there a "tipping point" at which the whole thing falls off of a cliff? Obviously, the $1 per gallon increase between 2003 and now was not enough to substantially reduce driving. The spike last summer evidently was enough to affect the consumers emotionally, but not structurally, so to speak--they cut back short-term but did not change their lives with the expectation that the situation was permanent. The period after the 1980 oil and interest rate catastrophe was quite different: Enough people lost their jobs, and started to drive less fuel-consuming cars that there was a semi-permanent decrease in consumption.
So, it remains to be seen what it will take, but per what we said earlier, $40 is possible but no one likes to think about what kind of a world we would be in if that was the case. The 2-3% economic contraction in 1981 gave us about a 15% decrease in the oil price over the next 3 years, so maybe 10% economic contraction would have to occur to get the current price from 65 to 40. That's about what happened at the start of the last depression. Also, as was pointed out earlier, something would have to happen suddenly and catastrophically enough for the price drop to take place within a year, to satisfy the assumption of the original question.
But that doesn't mean it's impossible.
