The failure of most forecasters to see the persistent inflation coming out of the pandemic has led to much soul-searching and questioning of the assumptions in computer economic simulations that have guided policy for many years.
“Our track record at understanding inflation is really, really bad,” University of California, Berkeley, professor David Romer said. “The range of plausible outcomes over the next year or two years is very, very wide,” including having inflation either fade or become embedded in the economy.
Reflecting that uncertainty, conference economists gave the Fed conflicting advice. Nobel laureate Joseph Stiglitz warned that tight credit would hurt the economy and do little to reduce inflation that’s been driven by supply shocks stemming from the pandemic and Russia’s invasion of Ukraine.
