Crises are a major driving force behind cooperation in the European Union. This holds also for monetary and fiscal policy. During severe crises, cooperation has been enlarged and intensified. The recent covid-19 pandemic is a clear example of this pattern. The pandemic has had huge impact on the...

This paper looks at the implications for monetary policy of the widespread adoption of artificial intelligence and machine learning, which is sometimes called the "fourth industrial revolution". The paper reviews experiences from the previous three industrial revolutions, developing a template...

In 1991, Canada became the second country to adopt an inflation target as a central pillar of its monetary policy framework. The regime has proven much more successful than initially expected, both in achieving price stability and in stabilizing the real economy against a wide range of shocks....

Theoretical analysis, empirical development and case studies show that room to manoeuvre stabilising macroeconomic policies during the COVID-19 crisis in the years 2020 and 2021 were fundamentally different in the Global South and Global North. The latter used extensive discretionary fiscal and...

Among LawMacro scholars, there is a growing interest in the incorporation of distributional goals into economic institutions and policies, especially central banks. We argue that this approach threatens to undermine the rule of law in monetary policy. This is troubling because the rule of law is...

We study the optimal monetary policy response to the imposition of tariffs in a model with imported intermediate inputs. In a simple open-economy framework, we show that a tariff maps exactly into a cost-push shock in the standard closed-economy New Keynesian model, shifting the Phillips curve...

Despite the theoretical prediction based on sticky-price models, it is empirically suggested that the tie between the frequencies of price adjustment across goods and the relative price responses of goods (price index of specific goods over non-durable aggregate price index) to a monetary policy...

I describe nine implications of the interconnectedness of fiscal and monetary policy that surface in Heterogeneous Agent New Keynesian (HANK) models. Not all are unique to HANK models. (i) Long run fiscal changes force monetary adjustments. (ii) Sustainable permanent deficits are feasible. (iii)...

We consider optimal monetary and fiscal policies in a New Keynesian model of a small open economy with sticky prices and wages.  In this benchmark setting monetary policy is all we need - analytical results demonstrate that variations in government spending should play no role in the...

It is widely believed that the Fiscal Theory of the Price Level (FTPL) does not work in an environment in which initial government debt is zero. This paper demonstrates that this view is incorrect when the government issues a set of financial assets restricted to standard nominal debt contracts...
