In an article published in The Regional Economist, Senior Economist Fernando Martin provided some historical context. He revisited some basic facts about prices and inflation since the founding of the U.S., including after the creation of the Fed.
Martin used two data series to measure price levels since 1790:
He noted that both measures paint a similar overall picture, including the existence of at least two different “eras” characterizing the behavior of prices:
“Overall, prices seem to move around a stable average during the pre-Fed era, while they have increased steadily since World War II,” he wrote.
Martin then looked at the changes in prices rather than their levels over time, using inflation measured by the yearly increase in the GDP deflator. (For a figure showing inflation since the U.S.’s founding, see the article “A Short History of Prices, Inflation since the Founding of the U.S.”)
“Before World War II, episodes of high inflation were followed by periods of deflation, which explains the fact that the price level moved around a stable average,” Martin said.
He noted that the inflationary episodes coincided with the convertibility of the dollar to gold and/or silver being suspended to meet the demand for additional government revenue. Examples include the Civil War and World War I.
When convertibility was reinstated and prices returned to their prewar levels, deflationary periods followed. “Although the price level was stable over the long run, inflation was very volatile during this period,” he said.
Martin highlighted two important inflationary episodes that explain a significant share of the price increases since World War II:
“High inflation was effectively defeated during Paul Volcker’s tenure as Fed chairman (1979-1987), and inflation has remained low and stable since,” he said.
While the post-World War II period exhibits the same recurrence of high inflation episodes as the preceding period, Martin noted that the lack of adherence to a metal-backed monetary system made the price level increase permanent rather than transitory. As a result, inflation volatility decreased significantly in the postwar period.
“In other words, with the joint creation of the Fed and the abandonment of metal convertibility of the currency, the economy traded off higher inflation for more stable inflation,” Martin said.
Martin explained that higher inflation is generally considered bad (since it taxes nominal asset holdings and cash transactions), while more-stable inflation is generally considered good (since it makes the future easier to predict). The latter leads to more-efficient economic decisions, lower costs of long-term (nominal) contracts and increased stability of the financial system.
He further explained that eliminating the need for deflation avoids having to endure the potentially costly and gradual process of price and wage reduction. He added that many households get hurt by deflation since the real burden of their debt (such as mortgage payments with a fixed-interest rate) increases as prices and nominal wages fall.
In summary, “Episodes of high inflation, which carry high economic costs, are nothing new and instead a recurrent feature in U.S. history,” Martin said. “In this regard, the important difference between the pre-Fed and the postwar eras is that these high-inflation episodes were previously followed by prolonged deflation and, in the more recent era, by a return to normal (and positive) inflation rates.”
