Diese Studie untersucht, ob Veränderungen kurzfristiger Zinsen die Kosten liquider Mittel beeinflussen und somit über Preissetzungsentscheidungen der Firmen auf die Inflationsdynamik in Industrieländern wirken. Barth und Ramey (2001) haben zum Beispiel für die USA gezeigt, dass...

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 analyze optimal monetary policy in a sticky price model where the central bank supplies money outright via asset purchases and lends money temporarily against collateral. The terms of central bank lending affect rationing of money and impact on macroeconomic aggregates. The central bank can...

This paper examines fiscal policy without commitment and the effects of conditional bailout loans. The government relies on distortionary taxation and decides between full debt repayment and costly default. It tends to overborrow due to myopia, which induces default to be a relevant policy...

This paper examines the pricing of public debt in a quantitative macroeconomic model with government default risk. Default may occur due to a fiscal policy that does not preclude a Ponzi game. When a build-up of public debt makes this outcome inevitable, households stop lending such that the...

This paper examines equilibrium determination under different monetary policy regimes when the government might default on its debt. We apply a cash-in-advance model where the government does not have access to non-distortionary taxation and does not account for initial outstanding debt when it...

Active interest rate policy is frequently recommended based on its merits in reducing macroeconomic volatility and being a simple and transparent policy device. In a standard New Keynesian model,we show that an even simpler policy, namely an interest rate peg, can be welfare enhancing: The...

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...

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...
