Paul Krugman doesn’t believe that the gold standard was a remedy to the ills of the Great Depression:
A while back I read Lionel Robbins’s 1934 book The Great Depression; as I pointed out, it was a Very Serious Person’s book for its era. Its solution was a return to the gold standard — which would have made things worse — and free trade, which was basically irrelevant to the problem of insufficient demand.
In fact, the gold standard is almost universally shunned (with a few notable exceptions) among academic economists. In a recent survey of academic economists, 93% disagreed or strongly disagreed with this statement:
If the US replaced its discretionary monetary policy regime with a gold standard, defining a “dollar” as a specific number of ounces of gold, the price-stability and employment outcomes would be better for the average American.
When we look at the Great Depression, we need to look at things on two levels: the causes, and the symptoms. Keynesian economists — particularly Krugman, Eichengreen, etc — are focused primarily on the symptoms, particularly depressed demand, and debt-deflation. Certainly, the gold standard is not a cure for the symptoms of an economic depression.
Trying to administer austerity after a crash like 1929 or 2008 is simply a road to more pain, and a deeper depression.
The principal attraction to the gold standard is to limit credit expansion to the productive capacity of the economy. But we know very clearly that — in spite of a gold standard — there was enough credit expansion during the 1920s for a huge bubble in stocks to form.
Ultimately — even with a gold standard — if a central bank or a government, (or in the most modern case, the shadow banking system) decide that the money supply will be drastically expanded, then limits on credit creation like the gold standard (or in the modern case, reserve requirements) will be no barrier.
The amusing thing, though is that gold — perhaps because of its history as money, perhaps because of its scarcity, and almost certainty because of its lack of counter-party risk — is as strong as ever. In a global financial system where the perception of debasement of currency is widespread, gold thrives. In an era where shareholder value is thrown under the bus in the name of CEO-remuneration, where corporations are perennially mismanaged, and where profit is too-often derived from bailouts and subsidies, gold thrives. It is a popular investment both for individual investors and for non-Western central banks.
The Federal Reserve’s monetary intransigence probably did prolong the Great Depression. Certainly there were other factors — including Hoover raising taxes. But none of that really matters now. Certainly, it is impossible that the United States — under its current monetary regime— would ever return to the gold standard. Gold’s role has changed. It is no longer state money. It is a stateless instrument thriving in a negative real-rate environment.
And unlike state monies whose values are subject to the decisions of states, gold will always be gold.
