We analyse the impact of interactions between monetary and fiscal policy on macroeconomic stability. We find that in the presence of sovereign default beliefs a monetary policy, which aims to stabilize inflation through an active interest rate policy, will destabilize the economy if the feedback...

We examine monetary policy options for a small open economy where sovereign default might occur due to intertemporal insolvency. Under interest rate policy and floating exchange rates the equilibrium is indetermined. Under a fixed exchange rate the equilibrium is uniquely determined and...

We present a simple macroeconomic model with open market operations that allows examining the effects of quantitative and credit easing. The central bank controls the policy rate, i.e. the price of money in open market operations, as well as the amount and the type of assets that are accepted as...

This paper examines monetary policy implementation in a sticky price model. The central bank's plan under discretionary optimization is entirely forward-looking and exhibits multiple equilibrium solutions if transactions frictions are not negligibly small. The central bank can then implement...

This paper assesses the transmission of fiscal policy shocks in a New Keynesian framework where government expenditures contribute to aggregate production. It is shown that even if the impact of government expenditures on production is small, this assumption helps to reconcile the models'...

We study optimal government spending in a business cycle model with frictional unemployment. The Ramsey optimal policy is contrasted with a reference policy which would be first best in a frictionless economy. Results are: the Ramsey policy i) implies a higher steady state ratio of government...

Blanchard (2005) suggested that active interest rate policy might induce unstable dynamics in highly-indebted economies. We examine this in a dynamic general equilibrium model where Calvo-type price rigidities provide a rationale for inflation stabilization. Unstable dynamics can occur when the...

In this paper, we analyze the relation between interest rate targets and money supply in a (bubble-free) rational expectations equilibrium of a standard cash-in-advance model. We examine lump-sum injections of money aimed to implement interest rate sequences that satisfy interest rate target...

We study the consequences of non-neutrality of government debt for macroeconomic stabilization policy in an environment where prices are sticky. Assuming transaction services of government bonds, Ricardian equivalence fails because public debt has a negative impact on its marginal rate of return...

Federal Reserve nonborrowed reserve supply systematically responded to changes in inflation and in the output gap over the period 1969-2000. While the feedback from output gap is always negative, the response of money supply to changes in inflation varies considerably across time. Nonborrowed...
