The guys who wrote Freakonomics (a fun read if you've missed it), write a blog. Since their whacky brand of economic research touches nearly everything, I wasn't completely suprised to see a post on the economic underpinnings of wine prices in restaurants.
I think the point that gets missed here is that there's only so much Joseph Phelps 2002 Insignia to be had.

The issue is not that scarcity leads to higher prices, but that there is a surprising difference from restaurant to restaurant, where the same bottle in the same market can go for $50 at one, and over $100 down the street. See, for example, http://www.dis-equilibrium.com/2007/09/restaurant-wine-prices.html

what is a fair way to price restaurant wine, by the glass and by the bottle?
Thanks
