I read in the NY Times this morning two very good articles related to food pricing.
The first is on price elasticity of demand (PED), related to how people are changing the ways they eat during the current economic downturn.
(Here's a good primer for everyone to read in order to learn -- or brush up on -- what the term "elasticity" means. If you don't read anything else in this post, read this.)
The second article is about proposed solutions (i.e., taxes) for the carbon costs of transporting food around the world. Who should pay these costs? Growers? Shippers? Retailers? Consumers?
