Abstract

The global commodity super-cycle is hardly a new phenomenon. Though the details vary, primary commodity exporters tend to act out the same story, and economic outcomes tend to follow recognizable patterns. But the element of predictability in the path of the commodity-price cycle, like that in the course of a roller coaster, does not make its twists and turns any easier to stomach.
