Many mainstream economists, perhaps a majority of those who have an opinion, are opposed to tying a central bank’s hands with any explicit monetary rule. A clear majority oppose the gold standard, at least according to an often-cited survey. Why is that?
First some preliminaries. By a “gold standard” I mean a monetary system in which gold is the basic money. So many grains of gold define the unit of account (e.g. the dollar) and gold coins or bullion serve as the medium of redemption for paper currency and deposits. By an “automatic” or “classical” gold standard I mean one in which there is no significant central-bank interference with the functioning of the market production and arbitrage mechanisms that equilibrate the stock of monetary gold with the demand to hold monetary gold. The United States was part of an international classical gold standard between 1879 (the year that the dollar’s redeemability in gold finally resumed following its suspension during the Civil War) and 1914 (the First World War).
Why isn’t the gold standard more popular with current-day economists? Milton Friedman once hypothesized that monetary economists are loath to criticize central banks because central banks are by far their largest employer. Providing some evidence for the hypothesis, I have elsewhere suggested that career incentives give monetary economists a status-quo bias. Most understandably focus their expertise on serving the current regime and disregard alternative regimes that would dispense with their services. They face negative payoffs to considering whether the current regime is the best monetary regime.
Here I want to propose an alternative hypothesis, which complements rather than replaces the employment-incentive hypothesis. I propose that many mainstream economists today instinctively oppose the idea of the self-regulating gold standard because they have been trained as social engineers. They consider the aim of scientific economics, as of engineering, to be prediction and control of phenomena (not just explanation). They are experts, and an automatically self-governing gold standard does not make use of their expertise. They prefer a regime that values them. They avert their eyes from the possibility that they are trying to optimize a Ptolemaic system, and so prefer not to study its alternatives.
