Robert Lucas, one of the greatest macroeconomists of his generation, and his followers are “making ancient and basic analytical errors all over the place”. Harvard's Robert Barro, another towering figure in the discipline, is “making truly boneheaded arguments”. The past 30 years of macroeconomics training at American and British universities were a “costly waste of time”.

Full Planet, Empty Plates: The New Geopolitics of Food Scarcity

by Lester R. Brown

Food is the new oil,” Lester R. Brown writes.

What will the geopolitics of food look like in a new era dominated by scarcity and food nationalism? Brown outlines the political implications of land acquisitions by grain-importing countries in Africa and elsewhere as well as the world’s shrinking buffers against poor harvests.
