Debt Stabilisation Bias and the Taylor Principle: Optimal Policy in a New Keynesian Model with Government Debt and Inflation Persistence.
Leith and Wren-Lewis (2007) have shown that government debt is returned to its pre-shock level in a New Keynesian model under optimal discretionary policy.

| الملخص: | Leith and Wren-Lewis (2007) have shown that government debt is returned to its pre-shock level in a New Keynesian model under optimal discretionary policy. This has two important implications for monetary and fiscal policy. First, in a high-debt economy, it may be optimal for discretionary monetary policy to cut the interest rate in response to a cost-push shock--thereby violating the Taylor principle--although this will not be true if inflation is significantly persistent. Second, the optimal fiscal response to such a shock is more active under discretion than commitment, whatever the degree of inflation persistence. |
