In 1980, Julian Simon offered to let doomsayer Paul Ehrlich choose any commodity metals he liked, and if their inflation-adjusted prices increased by 1990, Simon would pay $1000. But if they fell, Ehrlich would pay. The question was: would human ingenuity figure out ways to conserve on these metals, and/or find substitutes for them? By 1990, all five metals had fallen in price, and Ehrlich paid up. What does it all mean? That's what we discuss today.
