We augment a standard macroeconomic model to analyze the effects and limitations of balance sheet policies. We show that the central bank can stimulate real activity by changing the size or the composition of its balance sheet, when interest rate policy is ineffective. Specifically, the central...

Due to the US dollar's dominant role for international trade and finance, risk-free assets denominated in US currency not only offer a pecuniary return, but also provide transactions services, both nationally and internationally. Accordingly, the responses of bilateral US dollar exchange rates...

This paper questions unconventional fiscal policy effects when the monetary policy rate is at the zero lower bound. We provide evidence for the US that the spread between the policy rate and the US-LIBOR, which is more relevant for private sector transactions, increases with government...

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 reexamines the role of open market operations for short-run effects of monetary policy in a New Keynesian framework. The central bank supplies money in exchange for securities that are discounted with the short-run nominal interest rate, while money demand is induced by a liquidity...

We develop a macroeconomic model where the government does not guarantee to repay debt. We ask whether movements in the price of government bonds can be rationalized by lenders' unwillingness to fully roll over debt when the outstanding level of debt exceeds the government's repayment capacity....

In this paper it is shown that money can matter for macroeconomic stability under interest rate policy, if transactions frictions are specified in a consistent way. We develop a sticky price model with a shopping time specification, which induces the marginal utility of consumption to depend on...

We study the consequences of non-neutrality of government debt with respect to aggregate demand for short-run macroeconomic stability and for fiscal-monetary policy interactions in an environment where prices are sticky. Assuming either transaction services of government bonds or partial debt...
