Fiat money requires no backing to be accepted at a uniquely determined positive value. I show this using an equilibrium model with realistic frictions and rational households allowed to freely interact in a competitive environment. The model portrays a modern 'cashless' economy relying on...

This paper addresses the perspective of Hayek's doctrine on monetary arrangements in the economy and his favorable argument for an international central bank over national central bank. I also discussed Hayek's view on free banking (i.e. for the free issue of bank notes) that would enable the...

Part of the present inflation is caused by the breakdown of globalization, in particular supply chains, part is caused by the Corona Pandemic, in particular lockdowns, part is caused by the Ukrainian War, part is caused by European sanctions, and part - and not the smallest one - is caused by...

We consider monetary-policy rules with inflation-rate targets and interest-rate or money-growth instruments using a flexible-price, perfect-foresight model. There is always a locally-unique target equilibrium. There may also be below-target equilibria (BTE) with inflation always below target and...

The adoption of a "makeup'' strategy is one of the proposals adopted in the ongoing review of the Fed's monetary policy framework. Another suggestion, to avoid the zero lower bound, is a more active role for fiscal policy. We put together these ideas to study monetary-fiscal interactions under...

In this paper we contribute to the literature on environments with active fiscal and accommodating monetary policy. We show that this framework is able to explain the positive relationship between the steady state level of inflation and business cycle inflation volatility observable in the data....

A low-inflation mystery emerged during the 2010-2019 period as the Federal Reserve struggled to hit its two percent inflation target. This paper presents theoretical results and empirical evidence that points to the safe asset shortage as a key reason for the low inflation during this time....

This paper explicitly models strategic interaction between two independent national fiscal authorities and a single central bank in a simple New Keynesian model of a monetary union. Monetary policy is constrained by the zero lower bound on nominal interest rates. Coordination of fiscal policies...

We show that policy uncertainty about how the rising public debt will be stabilized accounts for the lack of deflation in the US economy at the zero lower bound. We first estimate a Markov-switching VAR to highlight that a zero-lower-bound regime captures most of the comovements during the Great...
