The fiscal theory states that inflation adjusts so that the real value of government debt equals the present value of real primary surpluses. Monetary policy remains important. The central bank can set an interest rate target, which determines the path of expected inflation, while news about the...

This paper describes the challenges of globalization in terms of the logic underpinning four distinct policy constraints or "trilemmas" and their interrelationship; in particular the disturbances that arise from capital flows and the difficulties of adjusting monetary policies to a global...

We show that if the central bank operates without commitment and faces constraints on its balance sheet, helicopter drops can be a useful stabilization tool during a liquidity trap. With commitment, even with balance sheet constraints, helicopter drops are irrelevant

We apply ideas from fiscal federalism to reassess how fiscal authority should be delegated within a monetary union. In a real-economy model with no fiscal externalities, in which local fiscal authorities have an informational advantage about the preferences of their citizens for public spending...

Emerging countries exhibit volatile fiscal policies and frequent sovereign debt crises, that significantly diminish the well-being of their citizens. International advisors typically suggest developed-world solutions as a remedy. We argue that the root of the problem lies in the institutional...

We study the role of trade policy in one of the most pressing climate policy challenges that developing countries face: meeting voluntary emission restraints (VERs). To do so, we develop a general equilibrium trade model that extends Caliendo and Parro (2015) in three dimensions. First, we model...

We build a tractable New Keynesian model to jointly study four types of monetary and fiscal policy. We find quantitative easing (QE), lump-sum fiscal transfers, and government spending have the same effects on the aggregate economy when fiscal policy is fully tax financed. Compared with these...

The post-COVID price surge has reignited interest in inflation's impact on American households. Even if anticipated and with full market adjustments, inflation affects households through its interaction with the fiscal system, which is the focus of this paper. Inflation affects households...

We characterize how firms structure supply chains under climate risk. Using new data on the universe of firm-to-firm transactions from an Indian state, we show that firms diversify sourcing locations, and suppliers exposed to climate risk charge lower prices. Our event-study analysis finds that...

Monetary rules may have a large effect on the outcome of trade wars if central banks target the CPI inflation rate or more generally changes in the relative price of traded goods. We lay out a two-country open-economy model with sticky prices where countries engage in trade wars. In the presence...
