Who Best Predicted 2021-24 Inflation?

Consumers, CEOs, or economists?

The forecast errors look like this:

While expert forecasts have missed inflation, they have reached an actual decline from May 2023 onwards.

Although economists were more biased in their expectations in this period, under-predicting inflation in one year, the root mean square error (RMSE) of economic forecasts was lower than that of firms, and almost the same as that of consumers. Of these three measures, only the strict expectation fails to reject the no-bias null.

On the other hand, conservative CEOs predict an overshoot in inflation in the near future.

In terms of correcting forecasts in response to errors, consumers move slowly (as measured by the AR(3) of errors, close to unity). Firms are next, at 0.89, and economists are fastest at 0.81.
