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 Covid pandemic disrupted supply chains and labor markets, with heterogeneous effects on demand and supply across industries. Meanwhile governments responded with unprecedented stimulus packages, and inflation increased to its highest values in 40 years. In this paper I investigate the...

I analyze monetary policy with interest on reserves and a large balance sheet. I show that conventional theories do not determine inflation in this regime, so I base the analysis on the fiscal theory of the price level. I find that monetary policy can peg the nominal rate, and determine expected...

This paper builds on Baqaee and Farhi (2022) and di Giovanni et al. (2022) to quantify the contribution of fiscal policy on U.S. inflation over the Dec-2019 to June-2022 period. Model calibrations show that aggregate demand shocks explain roughly two-thirds of total model-based inflation, and...

We find that financial conditions in the core have significant spillover effects on cross-border mergers and acquisitions (M&As). On average, a 1 percentage point easing of the IMF US Financial Conditions Index is associated with approximately a 10% higher volume of cross-border M&As. The...

Governments around the world have gone on a massive fiscal expansion in response to the Covid crisis, increasing government debt to levels not seen in 75 years. How will this debt be repaid? What role do conventional and unconventional monetary policy play? We investigate debt sustainability in...

We present a signalling theory of Quantitative Easing (QE) at the zero lower bound on the short term nominal interest rate. QE is effective because it generates a credible signal of low future real interest rates in a time consistent equilibrium. We show these results in two models. One has...

We address the question of how sensitive is the power of fiscal policy in the ZLB to the assumption of rational expectations. We do so through the lens of a standard NK model in which people are level-k thinkers. Our analysis weakens the case for using government spending to stabilize the...

This paper reconsiders the degree to which macroeconomic stabilization is possible when the zero lower bound is a relevant constraint on the effectiveness of conventional monetary policy, under an assumption of bounded rationality. In particular, we reconsider the potential role of...

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...
