Views on commodities and energy
The Becker-Posner Blog has an interesting debate posted on the question of food shortages and their accompanying price rises. As usual, it is a to-and-fro between economist and Nobel laureate Gary Becker and his University of Chicago colleague Richard Posner, a U.S. appellate judge.
Becker reckons that some commodity prices will rise as the global economy recovers but that food is different.
"Rapid growth in future world GDP is likely to greatly raise the prices of oil and other fossil fuels, unless concerns about global warming induce major steps to reduce the demand for these fuels. Rapid growth in world output is also likely to sharply raise the demand for cereals, meat, and other foods in developing countries. However, I have tried to show why food is different from fossil fuels and minerals, like copper, in that the supply of food is not limited by natural bounds on overall quantity. Rather, the efforts and ingenuity of farmers and researchers are able to greatly increase world food supply to meet even very large increases in the world demand for food."
Posner is not so sure, questionning the impact of technology on food production::
