Every time we see oil prices go up we hear that it will cause inflation and/or the economy will go into the tank.
... 7 out of the 8 postwar U.S. recessions had been preceded by a sharp increase in the price of crude petroleum. Iraq’s invasion of Kuwait in August 1990 led to a doubling in the price of oil in the fall of 1990 and was followed by the ninth postwar recession in 1990-91. The price of oil more than doubled again in 1999-2000, with the tenth postwar recession coming in 2001. Yet another doubling in the price of oil in 2007-2008 accompanied the beginning of recession number 11, the most recent and frightening of the postwar economic downturns. So the count today stands at 10 out of 11, the sole exception being the mild recession of 1960-61 for which there was no preceding rise in oil prices. [Hamilton [14], 2009. Rv. 2010]
The premise is wrong. What causes price inflation is an expansion of money supply (and a desire of people to spend it, often quickly). What causes recessions is malinvestment of capital caused, again, by money supply expansion.
The classic argument is that because 70% of the economy is driven by consumer spending, an increase in gasoline prices will cause a decrease in consumer spending, which will cause an economic decline. Sounds logical on its face. There are empirical studies that show either increases in gasoline prices will not impact discretionary spending (McCarthy [15], 20110) or that large increases in petroleum prices will cause recessions (Hamilton [14]). Take your pick.

The above chart1 shows the peak of real YoY GDP percentage change (light blue lines) and the relative price of gasoline (red), the product that most directly affects consumers. If gasoline prices have been increasing prior to the peak, then there is statistical data showing that those prices may have had an impact on GDP. From that one might conclude that because oil prices were rising prior to the peak in GDP, and because GDP subsequently declined, then high oil prices may have caused a decline in GDP. (Because A happened and then B happened, thus A caused B?) Or, is it just a coincidence?
What we see in the data is coincidence rather than confirmation.
Take price increases of oil and gasoline. It doesn't cause price inflation (i.e., all prices rise). Instead it's a supply and demand thing. When OPEC jacks up oil prices, people spend more on gas and less on other things. The consumer goods they don't buy decline in price. Money is redirected by market forces to petroleum producers who are incentivized to discover and produce more oil. Ultimately, under normal circumstances, prices come down. This process is a bit distorted because we have a cartel-controlled market. But, if OPEC keeps prices too high, people reduce consumption, cartel revenues go down, and OPEC reduces prices to stimulate consumption. This is what happened in the current business cycle.
It is the same with recessions and oil prices. Each of the recessions we've had in the last 40 years can be adequately explained by causes other than oil/gas prices. For example, while oil/gas prices shot up prior to the 2008 Crash, no one suggests that was a cause of it. Rather we know that oil prices went up as a result of a fiat money fueled boom that drove up all commodity prices.
Looking at our chart, we can start with the 1973 - 1975 recession. That was the time of the Arab Oil Embargo (Oct. 1973 to March 1974). If the theory that high oil prices equals recession holds true then why did the economy recover when gas prices continued to rise post-recovery? What really happened was that the Fed cut interest rates by half in 1970-1971, and then started raising them in 1973 to combat rising prices. By the time the recession started in November 1973, the Fed Funds rate peaked at just over 10%. It isn't as if the oil embargo didn't cause disruption in the economy; it did, but most of the economic disruption was caused by the government's price controls and rationing. But it didn't cause the recession.
Next, GDP peaked in April 1978 (gasoline-PPG $0.631) and declined until October 1980 ($1.223). Recall that price inflation almost hit 15% in 1980. The recession started in January 1980 ($1.11) and ended in July 1980 ($1.247). Gasoline prices continued to increase during the subsequent recovery. There is no correlation between oil prices and recession or price inflation.
GDP peaked again in Q2 1981 ($1.353) and bottomed out in November 1982 ($1.268). We went into recession in July 1981 ($1.353) until November 1982 ($1.268). You can see an oil price correlation here, but other things were going on: high inflation. By June 1981, the CPI was still over 10%. Carter had appointed Paul Volcker as Fed Chairman in August 1979 and he started raising the Fed Funds rate from around 10% until it reached 19% in January 1981, and kept it high (8% to 10%) for much his term (ended in 1987). This broke price inflation (it settled in the 3.5 to 4.5 range). Thus monetary policy rather than oil prices was the cause of the recession.
From then on, gasoline prices declined and remained relatively stable until 1999 ($0.90 to $1.30) when it started climbing again. The July 1990 ($1.139) to March 1991 ($1.138) recession shows that GDP peaked in late 1987 (about $0.95) and gasoline prices peaked in January 1991 ($1.304) and the recession ended in March 1991. But again, other things were driving the economy: a real estate boom-bust cycle, and that was largely driven by cheaper money and accelerated depreciation rules (those rules ended in 1986).
Prices fluctuated but remained in the $1.20s for most of the next eight years.
By 1999, the rise in gasoline prices coincided with peak GDP in late 1999 (Dec., $1.353) and gas prices rose, almost steadily since then. The 2001 recession came and went (March-$1,503) — November-$1.324). But, what else was going on? This was a time of incredible production and technological innovation that again benefited from the Fed's cheap money (spurred by Greenspan to revive the economy from the 1990 - 1991 recession). It worked. But Dot Com boom turned into Dot Bomb bust as the Fed raised interest rates and cooled the economy off from its "irrational exuberance".
The Fed decided it needed to stimulate the economy from the bust and from November 2000 to June 2004, the Fed lowered interest rates from 6.5% to 1.00%. From then on oil prices followed commodities prices and gasoline prices continued to climb.
By late 2003 ($1.578) the rate of growth of GDP peaked and thereafter was slowing, although it continued to grow until January 2006 ($2.359). At this point, the Fed again sought to cool down the economy and the Fed Funds rate went from 1.00% up to 5.26% by July 2007. Again, it worked and the real estate markets began to come apart. By H2 2008 ($4.142), GDP began to decline, thus beginning the bust phase of our current boom-bust cycle. Current price is $3.591.
Thus, while you can argue that rising oil and gas prices may have had some negative effects on the economy because of some economic disruption, in every case, the cause of our recession was anything but rising prices.
Regardless you are still going to hear that rising oil and gas prices are going to ruin the economy and cause us to go back into recession. While I believe the economy will decline starting in H2 2012, the reasons have nothing to do with oil prices. Don't let the pundits scare you with this economic fallacy. There is enough to worry about.
