We propose a general equilibrium model that explains the empirical evidence of the hump-shaped response of inflation to a monetary policy shock. The model replaces backward-looking indexation à la Christiano et al. [2005. Nominal rigidities and the dynamic effect of a shock to monetary policy. Journal of Political Economy 113(1), 1–45] with a dynamic externality into the production function of firms. The model, armed with sticky wages and variable capital utilization, has two offsetting effects on real marginal cost over the business cycle. First, increasing factor prices raise real marginal cost in response to an expansionary monetary policy shock in the intermediate run. Second, a dynamic externality reduces real marginal cost in the short run because it raises productivity in response to an increase in output following the shock. Overall, the resulting short-run decrease and intermediate-run increase in marginal cost replicate the hump-shaped behavior of inflation under purely forward-looking price and wage Phillips curves.

We study how constrained fiscal policy can affect macroeconomic stability and welfare in a two-region model of a monetary union with sticky prices and distortionary taxation. Both government spending and taxes can be used to stabilize regional variables; however, the best welfare outcome is obtained under some tax variability and constant regional inflations. We use a variety of rules to characterize constrained fiscal policy and find that strict fiscal rules coupled with a monetary policy that targets union-wide inflation result in regional inflation stability and the welfare costs of such rules are not as unbearable as one would expect. Fiscal authorities can enhance welfare by targeting the regional output gap, while targeting regional inflation is less successful since inflation stability is guaranteed by the central bank.
