And yet none of this has happened.

Both inflation and unemployment are headed in the right direction, and most economists expect the US to avoid a recession in 2024.

And a year ago, I think many economists were saying a recession was inevitable. I’ve never felt there was a solid intellectual basis for making such a prediction." Many of those economists may have been relying on the work of … Janet Yellen. Her own (highly regarded) macro research focuses on nominal price and wage stickiness and output-inflation trade-offs, predicting that if there is a significant fall in aggregate demand, employment should also fall, giving rise to a recession.

She is also co-author (with many distinguished colleagues) of a well-known paper arguing that there is an output/inflation trade-off even at high rates of inflation. Economist Christina Romer (often with co-authors) has provided some of the most persuasive evidence that negative monetary policy shocks induce recessions in output and employment. Her work has been especially influential — worthy of a Nobel Prize, in my opinion — because it does not
