Abstract

We document how the interaction of supply-chain pressures, heightened household inflation expectations, and firm pricing power contributed to the pandemic-era surge in consumer price inflation in the euro area. Initially, supply-chain pressures increased inflation through a cost-push channel and raised inflation expectations. Subsequently, the cost-push channel intensified as firms with high pricing power increased product markups in sectors witnessing high demand. Eventually, even though supply-chain pressures eased, these firms were able to further increase markups due to the stickiness of inflation expectations. The resulting persistent impact on inflation suggests supply-side impulses can generalize into broad-based inflation via an interaction of household expectations and firm pricing power.
