Climate change is one of the greatest challenges of this century. Mitigation requires a large-scale transition to a low-carbon economy. This paper provides an overview of the rapidly growing literature on the role of macroeconomic and financial policy tools in enabling this transition. The...

I study a class of macroeconomic models in which all firms can costlessly choose any price at each date from an interval (indexed to last period's price level) that includes a positive lower bound. I prove three results that are valid for any such half-closed interval (regardless of how near...

How should independent central banks react if pressured by fiscal policymakers? We study an environment with strategic monetary-fiscal interactions where the central bank has a limited degree of commitment to follow policies over time and the fiscal authority has none. We contrast the...

We analyse the effectiveness of optimal simple and implementable monetary and fiscal policy rules in stabilising economic activity, inflation and government debt in face of an occasionally binding lower bound on the nominal interest rate in a New Keynesian model. We show that, within the...

Das Jahr 2022 – ein Zeitenumbruch. Inwiefern ist dieser Zeitenumbruch mit einem gesellschaftlichen Gestaltungswillen verbunden? Der vorliegende Artikel will Argumente dafür liefern, diesen Zeitenumbruch im aktiven Sinne zu verstehen – als Ausdruck der kooperativen Gestaltung und des...

The combination of discretionary monetary policy, labor-market distortions and nominal wage rigidity yields an inflation bias as monetary policy tries to exploit nominal wage contracts to address labour-market distortions Although an inflation target eliminates this inflation bias, it creates a...

We explore the dynamics of public debt in the presence of political shocks, in the form of shocks to preferences for public spending. Under commitment, optimal stabilization is obtained by combining an inflation target that is contingent on the political shock with a debt target that forces the...

Weak public institutions, including high levels of corruption, characterize many developing countries. With a simple model, we demonstrate that institutional quality has important implications for the design of monetary policies and can produce several departures from the conventional wisdom. We...

This paper explores the interaction between centralized monetary policy and decentralized fiscal policy in a monetary union. Discretionary monetary policy suffers from a failure to commit. Moreover, decentralized fiscal policymakers impose externalities on each other through the influence of...

This paper explores under what conditions a European Monetary Union (EMU) is an optimum currency area. The scope for an EMU increases with convergence of structural and fiscal policies, small money holdings, a conservative European Central Bank, and dependent national central banks. How national...
