Three views on ridiculous commodity prices these days, from Krugman...
Running Out of Planet to Exploit - New York Times:
"The first is that it’s mainly speculation — that investors, looking for high returns at a time of low interest rates, have piled into commodity futures, driving up prices. On this view, someday soon the bubble will burst and high resource prices will go the way of Pets.com.
The second view is that soaring resource prices do, in fact, have a basis in fundamentals — especially rapidly growing demand from newly meat-eating, car-driving Chinese — but that given time we’ll drill more wells, plant more acres, and increased supply will push prices right back down again.
The third view is that the era of cheap resources is over for good — that we’re running out of oil, running out of land to expand food production and generally running out of planet to exploit."
