Why do workers dislike inflation even when real wages hold up?
Core argument: In a survey of workers, respondents were willing to sacrifice 1.75% of their wages to avoid the costly actions ("conflict") needed to make nominal wages catch up with inflation.
We argue that workers must take costly actions (“conflict”) to have nominal wages catch up with inflation, meaning there are welfare costs even if real wages do not fall as inflation rises. We show that, following a rise in inflation, wage catchup resulting from more frequent conflict does not raise welfare. Instead, the impact of inflation on worker welfare is determined by what we term “wage erosion”—how inflation would lower real wages if workers' conflict decisions did not respond to inflation. As a result, measuring welfare using observed wage growth understates the costs of inflation. We conduct a survey showing that workers are willing to sacrifice 1.75% of their wages to avoid conflict. Calibrating the model to the survey data, the aggregate costs of inflation incorporating conflict more than double the costs of inflation via falling real wages alone. The right figure[s] in Figure 11 shows the dynamic response of real wages and welfare-relevant wage erosion for the 2021-23 inflation surge. The gap between real wages and wage erosion [right panels] measures the large aggregate costs of inflation due to conflict.
