Interesting article by Marijn A. Bolhuis, Judd N. L. Cramer, Lawrence H. Summers, They estimate past US inflation using today’s methodology and realise that inflation trends today are quite similar to 1970s:
Housing inflation in the US before 1983 was measured in a way that made the Consumer Price Index (CPI) mechanically responsive to Fed policy, leading to artificially high peaks and fast declines in CPI inflation. To better contextualise the current run-up in inflation to a 40-year high, this column presents new historical series for CPI headline and core inflation that are more consistent with current practices and expenditure shares for the post-war period. Using these series, the authors find that current inflation levels are much closer to past inflation peaks than the official series would suggest.
Implications:
Previous inflationary cycles look more volatile and responsive to Fed policy due to differences in how housing inflation was measured before and after 1983. We highlight three implications.
First, our observations indicate that the current inflation regime is considerably closer to that of the late 1970s than it appears if inflation rates are compared straightforwardly. Our corrected estimates suggest that core CPI inflation is now at levels experienced in 1979.
Second, we conclude that it is misplaced to glean the effects of monetary tightening from the published CPI disinflation Paul Volcker achieved in the early 1980s. Volcker’s rate of core CPI disinflation is significantly slower when measured using today’s methods. At the speed achieved in the 1980s, using this corrected estimate, it would take today’s headline CPI about three years to return to 2%.
Finally, many commenters have said that monetary policy works through housing – that was clearly the case in the past. Once rates stabilized shelter inflation plunged mechanically. Today, given the lag structure of shelter inflation discussed elsewhere (Bolhuis et al. 2022a), residential services are likely to be a significant hindrance to declines in headline and especially core inflation. This could be a headache for the Fed even after housing prices stop rising at double-digit rates.
