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...

Evidence from vector autoregressions indicates that the impact of interest rate shocks on macroeconomic aggregates can substantially be affected by the so-called cost channel of monetary transmission. In this paper we apply a structural approach to examine the relevance of the cost channel for...

This paper reexamines the role of open market operations for short-run effects of monetary policy. Money demand is induced by a cash constraint, while the central bank supplies money exclusively in exchange for securities, discounted with a short-run nominal interest rate. We consider a legal...

This paper examines how credit market frictions affect optimal monetary policy and if there is a role for central bank asset purchases. We develop a sticky price model where money serves as the means of payment and ex-ante identical agents borrow/lend among each other. The credit market is...

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...

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...

This paper examines whether the U.S. Federal Reserve has adjusted high-powered money supply in response to macroeconomic indicators. Applying ex-post and real-time data for the postwar period, we provide evidence that nonborrowed reserves responded to expected inflation and the output-gap. While...

We develop a macroeconomic framework where money is supplied against only few eligible securities in open market operations. The relationship between the policy rate, expected inflation and consumption growth is affected by money market conditions, i.e. the varying liquidity value of eligible...
