The economic characteristics of the COVID-19 crisis differ from those of previous crises. It is a combination of demand- and supply-side constraints which led to the formation of a monetary overhang that will be unfrozen once the pandemic ends. Monetary policy must take this effect into...

What are the macroeconomic consequences of a government that is limited in its willingness or ability to raise primary surpluses, and a central bank that accommodates its interest-rate policy to the fiscal conditions? I address this question in a dynamic stochastic sticky-price model with...

This paper leverages a novel survey among German senior government officials to investigate fiscal responses to monetary policy shocks. Using randomized vignette treatments, we present officials with scenarios of increased government interest costs and analyze their expected fiscal adjustments....

This thesis was written by Jakob Eberl while having been a research assistant at the Center for Economic Studies (CES) at the University of Munich. It was completed in December 2015 and accepted as a doctoral thesis by the Department of Economics at the University of Munich in May 2016. The...

Japan has experienced stagnation, deflation, and low interest rates for decades. It is caught in a liquidity trap. This paper examines Japan’s liquidity trap in light of the structure and performance of the country’s economy since the onset of stagnation. It also analyzes the country’s...

The monetary and fiscal policy interactions have gained a new research interest after the 2008 crisis due to the global increase of fiscal debt. This paper constructs a macroeconomic model of joint fiscal and monetary policy for an emerging open economy taking into account its structural...

I characterize optimal monetary and fiscal policy in a stochastic New Keynesian model when nominal interest rates may occasionally hit the zero lower bound. The benevolent policymaker controls the short-term nominal interest rate and the level of government spending. Under discretionary policy,...

How does the need to preserve government debt sustainability affect the optimal monetary and fiscal policy response to a liquidity trap? To provide an answer, we employ a small stochastic New Keynesian model with a zero bound on nominal interest rates and characterize optimal time-consistent...

This paper has two main objectives. The first is to propose a policy architecture that can prevent a very high public debt from resulting in a high tax burden, a government default, or inflation. The second objective is to show that government deficits do not face a financing problem. After...

I show that the zero nominal interest rate bound may render it desirable for society to appoint a fiscally activist policy-maker who cares less about the stabilisation of government spending relative to inflation and output gap stabilisation than the private sector does. I work with a simple New...
