One of the main contributions of Modern Money Theory (MMT) has been to explain why monetarily sovereign governments have a very flexible policy space that is unconstrained by hard financial limits. Not only can they issue their own currency to pay public debt denominated in their own currency,...

Not since the Great Depression have monetary policy matters and institutions weighed so heavily in commercial, financial, and political arenas. Apart from the eurozone crisis and global monetary policy issues, for nearly two years all else has counted for little more than noise on a relative...

We study the incidence and severity of lower-bound episodes and the efficacy of three types of state-dependent policies - forward guidance about the future path of interest rates, large-scale asset purchases and spending-based fiscal stimulus - in ameliorating the adverse consequences stemming...

We use scenario analysis to assess the macroeconomic effects of carbon transition policies aimed at mitigating climate change. To this end, we employ a version of the ECB's New Area-Wide Model (NAWM) augmented with a framework of disaggregated energy production and use, which distinguishes...

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...

We quantify the size of fiscal multipliers under financial fragmentation risk and demonstrate how non-standard monetary policy can support the macroeconomic transmission of fiscal interventions. We employ a DSGE model with financial frictions whereby the interplay of corporate, banks and...

How to conduct macro-prudential regulation? How to coordinate monetary policy and macro-prudential policy? To address these questions, I develop a continuous-time New Keynesian economy in which a financial intermediary sector is subject to a leverage constraint. Coordination between monetary and...

Historically high levels of private and public debt coupled with already very low short-term interest rates appear to limit the options for stimulative monetary policy in many advanced economies today. One option that has not yet been considered is monetary financing by central banks to boost...

This paper compares the role of monetary and fiscal policy shocks in advanced and emerging economies. Using a model with a hierarchical structure we capture the variability of GDP response to policy shocks both between and within the groups of advanced and emerging countries. Our results provide...

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...
