Trend inflation, endogenous mark-ups and the non-vertical Phillips curve

Recent developments in macroeconomics resurrect the view that wel- fare costs of inflation arise because the latter acts as a tax on money balances. Empirical contributions show that wage re-negotiations take place while expiring contracts are still in place. Bringing these seemingly unrelated aspects together in a stylized general equilibrium model, we ?nd a disciplining e¤ect of a positive inflation target on the wage markup and identify a long-term trade-off between in?ation and output.
