Economics is often a contentious subject, but economists agree about the gold standard -- it is a barbarous relic that belongs in the dustbin of history. As University of Chicago professor Richard Thaler points out, exactly zero economists endorsed the idea in a recent poll. What makes it such an idea non grata? It prevents the central bank from fighting recessions by outsourcing monetary policy decisions to how much gold we have -- which, in turn, depends on our trade balance and on how much of the shiny rock we can dig up. When we peg the dollar to gold we have to raise interest rates when gold is scarce, regardless of the state of the economy. This policy inflexibility was the major cause of the Great Depression, as governments were forced to tighten policy at the worst possible moment. It's no coincidence that the sooner a country abandoned the gold standard, the sooner it began recovering.
