This Paper computes welfare-maximizing monetary and tax policy feedback rules, in a calibrated dynamic general equilibrium model with sticky prices. The government makes exogenous final good purchases, levies a proportional income tax, and issues nominal one-period bonds. A quadratic...

We study the interplay between competition and trust as efficiency-enhancing mechanims in the private provision of money. With commitment, trust is automatically achieved and competition ensures efficiency. Without commitment, competition plays no role. Trust does play a role but requires a...

The recovery from the last recession has been slower than any other recovery in the post-WWII period both in the US and in many other advanced economies. There is an ongoing debate around the causes of such a slow recovery. Are there any structural factors that are constraining the speed of...

Motivated by the recent experience of the U.S. and the Eurozone, we describe the quantitative properties of a New Keynesian model with a zero lower bound (ZLB) on nominal interest rates, explicitly accounting for the nonlinearities that the bound brings. Besides showing how such a model can be...

This paper examines how supply-side policies may play a role in fighting a low aggregate demand that traps an economy at the zero lower bound (ZLB) of nominal interest rates. Future increases in productivity or reductions in mark-ups triggered by supply-side policies generate a wealth effect...

We characterize the optimal sequential choice of monetary policy in economies with either nominal or indexed debt. In a model where nominal debt is the only source of time inconsistency, the Markov-perfect equilibrium policy implies the progressive depletion of the outstanding stock of debt,...

The Paper studies the inflation rate associated with optimal monetary policy in a standard suite of DSGE models, when fiscal policy is either unrestricted optimal or restricted but supportive of monetary policy. Full nominal price flexibility, nominal prices set one period in advance and...

This Paper outlines some issues regarding the interaction of independent fiscal authorities and one central bank in the European monetary union. It points out the possibilities for coordination failures, ranging everywhere from potentially excessive deficits and free-riding problems to...

This Paper studies the structure and time consistency of optimal monetary policy from a public finance perspective in an economy where agents differ in transaction patterns and asset holdings. I find that heterogeneity breaks the link between lack of government commitment and high inflation,...

In this Paper we carry over a static version of a New Keynesian Macromodel a la Clarida Gali Gertler (1999) to a monetary union. We will show in particular that a harmonious functioning of a monetary union critically depends on the correlation of shocks that hit the currency area. Additionally a...
