Alan Blinder writes:
Thursday’s shocking report on first-quarter gross home product could contribute to a sense of déjà vu once more. Excessive inflation reminds many Individuals of the sad Nineteen Seventies, when a collection of food-price shocks in 1973-74 and an enormous oil-price shock late in 1973 drove inflation by the roof—and a critical recession adopted. Are we headed for a repeat efficiency?
Not fairly. One large distinction is that now the Federal Reserve and different central banks perceive stagflation a lot better. In 1973 it was a puzzling new phenomenon, and nobody knew how to consider it. Economists and central bankers of the day had lived by a historical past by which booming economies introduced on rising inflation and sluggish economies introduced on rising unemployment. The 2 maladies didn’t happen concurrently. (italics added)
That is from Alan S. Blinder, “If We Get a Recession in 2022 or 2023, It’ll Be a Delicate One,” Wall Road Journal, April 28, 2022. (April 29 print version.)
However right here’s what Milton Friedman stated in his presidential deal with to the American Economics Affiliation in December 1967:
Allow us to assume that the financial authority tries to peg the “market” charge of unemploymentat a stage under the “pure” charge. For definiteness, suppose that it takes 3 per cent because the goal charge and that the “pure” charge is greater than 3 per cent. Suppose additionally that we begin out at a time when costs have been secure and when unemployment is greater than 3 per cent. Accordingly,the authority will increase the speed of financial progress. This can be expansionary. By making nominal money balances greater than folks need, it’s going to have a tendency initially to decrease rates of interest and on this and different methods to stimulate spending. Revenue and spending will begin to rise.
To start with, a lot or a lot of the rise in earnings will take the type of a rise in output and employment somewhat than in costs. Folks have been anticipating costs to be secure, and costs and wages have been set for a while sooner or later on that foundation. It takes time for folks to regulate to a brand new state of demand. Producers will are likely to react to the preliminary growth in mixture demand by growing output, staff by working longer hours, and the unemployed, by taking jobs now supplied at former nominal wages. This a lot is fairly customary doctrine.
But it surely describes solely the preliminary results. As a result of promoting costs of merchandise sometimes reply to an unanticipated rise in nominal demand sooner than costs of things of manufacturing, actual wages acquired have gone down-though actual wages anticipated by staff went up, since staff implicitly evaluated the wages supplied on the earlier worth stage. Certainly, the simultaneous fall ex submit in actual wages to employers and rise ex ante in actual wages to staff is what enabled employment to extend. However the decline ex submit in actual wages will quickly come to have an effect on anticipations. Staff will begin to reckon on rising costs of the issues they purchase and to demand greater nominal wages for the longer term. “Market” unemployment is under the “pure” stage. There’s an extra demand for labor so actual wages will are likely to rise towards their preliminary stage.
Though the upper charge of financial progress continues, the rise in actual wages will reverse the decline in unemployment, after which result in an increase, which is able to are likely to return unemployment to its former stage. In an effort to hold unemploymentat its goal stage of three per cent, the financial authority must increase financial progress nonetheless extra.
In different phrases, Milton Friedman, properly earlier than the 1973 stagflation, anticipated that one can get “stagflation,” the mixture of excessive unemployment and excessive inflation.
What misled Alan Blinder is that the economists he studied underneath, Robert Solow and Paul Samuelson, didn’t anticipate this mix as a result of they have been blinded by their Keynesian Phillips Curve mind-set.
However that wasn’t the entire universe of economists. Friedman noticed it clearly over 5 years earlier than the 1973 stagflation.
Right here’s my bio of Milton Friedman in David R. Henderson, ed., The Concise Encyclopedia of Economics. Right here’s Kevin D. Hoover’s wonderful entry on the Phillips Curve within the Encyclopedia.
