چکیده

In this paper, we study Ramsey-optimal fiscal and monetary policy in a mediumscale model of the U.S. business cycle. The model features a rich array of real and nominal rigidities that have been identified in the recent empirical literature as salient in explaining observed aggregate fluctuations. The main result of the paper is that price stability appears to be a central goal of optimal monetary policy. The optimal rate of inflation under an income tax regime is half a percent per year with a volatility of 1.1 percent. This result is surprising given that the model features a number of frictions that in isolation would call for a volatile rate of inflation—particularly nonstate-contingent nominal public debt, no lump-sum taxes, and sticky wages. Under an income-tax regime, the income tax rate is quite stable, with a mean of 30 percent and a standard deviation of 1.1 percent. Simple monetary and fiscal rules are shown to implement a competitive equilibrium that mimics well the one induced by the Ramsey policy. When the fiscal authority is allowed to tax capital and labor income at different rates, optimal fiscal policy is characterized by a large and volatile subsidy on capital. JEL Classification: E52, E61, E63.

Fiscal Policy and the Implementation of the Walsh Contract for Central Bankers

We develop a simple macroeconomic model where the time inconsistency of optimal monetary policy is due to tax distortions. If fiscal policy is exogenously fixed at its optimal level, a Walsh contract (Walsh, 1995) offered to an independent central bank implements the optimal monetary policy. When fiscal policy is determined endogenously, however, this contract is subject to strategic manipulati...

Optimal Fiscal Policy in a Simple Macroeconomic Context

This article derives optimal fiscal rules within a stochastic model of Keynesian type in the context of Poole (1970) analysis. By using optimal control theory and applying the Hamilton-Jacoby-Bellman equation, we extend the original Poole results concerning the output stabilization properties of monetary policy to the case of fiscal policy. In particular, we look for the optimal setting of gove...

Optimal Fiscal Stabilisation through Government Spending

This paper examines under what conditions fiscal policy in the form of government spending should contribute to macroeconomic stabilisation. To this end optimal fiscal targeting rules minimising the microfounded social loss are examined in the following settings. Firstly, for the benchmark New Keynesian model, where monetary policy is unconstrained, a neutrality result for fiscal obtains: fisca...
