Would households understand average inflation targeting?

Yes, they would. In a randomized control trial, we provide groups of respondents from the Bundesbank Online Panel Households with information about a hypothetical alternative ECB monetary policy regime akin to the Federal Reserve’s flexible average inflation targeting (AIT). Inflation expectations significantly increase for the treated individuals. When we provide additional information about near-term inflation, for low levels of trust in the ECB the adjustment of inflation expectations tends to be negative while it is positive for intermediate and higher levels of trust. We assess the economic significance of our findings by comparing two model economies under different monetary policy strategies, calibrated to match the difference in medium-term inflation expectations from our survey results. Under AIT, inflation is substantially less volatile and the frequency of hitting the lower bound on interest rates is considerably reduced.
