Inflationary processes are closely linked to wage-price spirals - such spirals can be triggered by many factors, including natural resource price shocks, depreciation and inflationary demand. Empirically, the correlation between changes in nominal unit labour costs and the price level is strong...

Canonical menu cost models, when parameterized to match the micro-price data, cannot reproduce the extent to which the fraction of price changes increases with inflation. They also predict implausibly large menu costs and misallocation in the presence of strategic complementarities. We resolve...

The analysis of this paper demonstrates that when the Phillips curve has forward-looking components, a goal for average inflation - i.e. targeting a j-period average of one-period inflation rates - will cause inflation expectations to change in a way that improves the short-run trade-off faced...
