In this note we elaborate on the effect of the modeling choice of the zero lower bound on the size of the fiscal multiplier. To this end we contrast two different ways to implement the ZLB in a New Keynesian model: the ZLB modeled as an endogenous central bank reaction to a contractionary demand...

This paper proposes an equilibrium theory of nominal exchange rates, which offers a new perspective on various issues in open economy macroeconomics. The nominal exchange rate and portfolio choices are jointly determined in equilibrium, thus providing a new approach to overcoming the...

We study aggregate, distributional, and welfare effects of a permanent reduction in the capital tax rate in a dynamic equilibrium model with capital-skill complementarity. Such a tax reform leads to expansionary long-run aggregate effects, but is coupled with an increase in the skill premium....

How much does inequality matter for the business cycle and vice versa? Using a Bayesian likelihood approach, we estimate a heterogeneous-agent New-Keynesian (HANK) model with incomplete markets and portfolio choice between liquid and illiquid assets. The model enlarges the set of shocks and...

Central banks affect the resources available to fiscal authorities through the impact of their policies on the public debt, as well as through their income, their mix of assets, their liabilities, and their own solvency. This paper inspects the ability of the central bank to alleviate the fiscal...

We provide evidence that expansionary fiscal policy lowers the return difference between more and less liquid assets—the liquidity premium. We rationalize this finding in an estimated heterogeneous-agent New-Keynesian (HANK) model with incomplete markets and portfolio choice, in which public...

The argument that policy risk, i.e., uncertainty about monetary and fiscal policy, has been holding back the economic recovery in the U.S. during the Great Recession has a large popular appeal. We analyze the role of policy risk in explaining business cycle fluctuations by using an estimated New...

In this paper, sound public finances under the euro means sustainability in the long term instead of short- and medium-term fiscal discipline. The challenges to sustainability are identified for the four largest euro area member states, and several policy options for sustainability are...

The conflicting standpoints on reforming the euro are creating more controversies than practical results. Mistrust between the participants led to short-sighted fiscal discipline that has amplified the economic disturbances. Expert analysis on the proposed reforms is often deficient as the...

This paper examines the interaction of monetary and fiscal policies using an estimated New Keynesian dynamic general equilibrium model for the US. In contrast to earlier work using VAR models, we show that the strategic complementarity or substitutability of fiscal and monetary policy depends...
