Seven meals between civilization and anarchy?

Nobel laureate Amartya Sen weighs in on the food crisis in the NY Times:

Though the need for huge rescue operations is urgent, the present acute crisis will eventually end. But underlying it is a basic problem that will only intensify unless we recognize it and try to remedy it.

It is a tale of two peoples. In one version of the story, a country with a lot of poor people suddenly experiences fast economic expansion, but only half of the people share in the new prosperity. The favored ones spend a lot of their new income on food, and unless supply expands very quickly, prices shoot up. The rest of the poor now face higher food prices but no greater income, and begin to starve. Tragedies like this happen repeatedly in the world.

This is very much a demand-driven story in line with Sen’s research on the human causes of famine. But is it the right one?

Contrast this argument with Tom Slayton and Peter Timmer’s account, where hoarding, speculation, and trade restrictions take much of the blame. Indeed, the release of Japanese rice supplies last week eased speculation and price pressures. Rice prices are coming down.

In Congressional testimony, Arvind Subramanian also points to high fuel prices, stagnant agricultural productivity, and climate-change induced pressure on agricultural supplies.

Sen is undoubtedly right, but the contest between the haves and the have-nots is only a piece of the story.
