We analyze the interaction between committed monetary policy and discretionary fiscal policy in a model with public debt, endogenous government expenditures, distortive taxation and nominal rigidities. Fiscal decisions lack commitment but are Markovperfect. Monetary commitment to an interest...

We consider the interaction between monetary and fiscal policies, in one country and in a monetary union. In a Nash equilibrium, at least one of the outcomes (output and inflation) are more extreme than the ideal points of both policy authorities. We allow very general stochastic shocks to the...

We consider monetary-fiscal interactions when the monetary authority is more conservative than the fiscal. With both policies discretionary, (1) Nash equilibrium yields lower output and higher price than the ideal points of both authorities, (2) of the two leadership possibilities, fiscal...

We find and compare two simple fiscal rules. The first is a theoretical rule that approximates well Ramsey-optimal fiscal policy in a DSGE model calibrated to the U.S. economy over the period 1955:1 to 2007:3. The second is an empirical rule that approximates well actual U.S. fiscal policy over...

This paper uses a closed voting rule to explain how gradual changes in the socio-economic structure of developed societies shift political coalitions and lead to rapid expansions of transfer programs. Equilibria in a lifecycle economy with three homogeneous groups of voters (retirees, skilled...
