Lately I've been reading a lot of people stating that the run-up in oil prices in 2007-2008 didn't lead to an increase in production. This is false.
From the middle of 2007 to the middle of 2008, world crude oil production did, in fact, increase to the tune of 2+ million bpd, as this chart from October's TOD Oilwatch Monthly shows:
Compare this to the price. You can see the last big spike occurred starting around spring 2007. As recently as January 2007 the average price was around $54 (source).
Since the price crashed, as Economics 101 would predict, production has also crashed.

That was down to less than 72 million bpd as of January, but the April Oilwatch Monthly didn't put a handy-dandy world crude production chart on the TOD thread.
Pretty predictable stuff, actually.
