Inflation and Real Activity over the Business Cycle
We study the relation between inflation and real activity over the business cycle. We employ a Trend-Cycle VAR model to control for low-frequency movements in inflation, unemployment, and growth that are pervasive in the post-WWII period. We show that cyclical fluctuations of inflation are related to cyclical movements in real activity and unemployment, in line with what is implied by the New Keynesian framework. We then discuss the reasons for which our results relying on a Trend-Cycle VAR differ from the findings of previous studies based on VAR analysis. We explain empirically and ...

Escaping the Great Recession
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 Recession: a deep recession, no deflation, and large fiscal imbalances. We then show that a micro-founded model that features policy uncertainty accounts for these stylized facts. Finally, we highlight that policy uncertainty arises at the zero lower bound because of a trade-off between mitigating the ...

Monetary and Fiscal Policies in Times of Large Debt: Unity is Strength
The COVID pandemic hit the US economy at a time in which the ability of policymakers to react to adverse shocks is greatly limited. The current low interest rate environment limits the Federal Reserve's ability to stabilize the economy, while the large public debt curtails the efficacy of fiscal interventions by inducing expectations of costly fiscal adjustments. A solution to this impasse is a coordinated fiscal and monetary strategy aiming at creating a controlled rise of inflation to wear away a targeted fraction of debt. Under our coordinated strategy, the fiscal authority introduces an ...

Modeling the Evolution of Expectations and Uncertainty in General Equilibrium
We develop methods to solve general equilibrium models in which forward-looking agents are subject to waves of pessimism, optimism, and uncertainty that turn out to critically affect macroeconomic outcomes. Agents in the model are fully rational, conduct Bayesian learning, and they know that they do not know. Therefore, agents take into account that their beliefs will evolve according to what they will observe. This framework accommodates both gradual and abrupt changes in beliefs and allows for an analytical characterization of uncertainty. Shocks to beliefs affect economic dynamics and ...

Who is Afraid of Eurobonds?
The growing asymmetry in the size of fiscal imbalances poses a serious challenge to the macroeconomic stability of the Euro Area (EA). We show that following a contractionary shock, the current monetary and fiscal framework weakens economic growth even in low-debt countries because of the zero lower bound (ZLB) constraint. At the same time, the current framework also exposes the EA to the risk of fiscal stagflation if one country were to refuse to implement the necessary fiscal consolidations. We study a new framework that allows EA policymakers to separate the need for short-run ...

Hitting the Elusive Inflation Target
Since the 2001 recession, average core inflation has been below the Federal Reserve?s 2% target. This deflationary bias is a predictable consequence of a low nominal interest rates environment in which the central bank follows a symmetric strategy to stabilize inflation. The deflationary bias increases if macroeconomic uncertainty rises or the natural real interest rate falls. An asymmetric rule according to which the central bank responds less aggressively to above-target inflation corrects the bias and allows inflation to converge to the central bank?s target. We show that adopting this ...

Some inflation scenarios for the American Rescue Plan Act of 2021
The American Rescue Plan Act (ARP) signed into law on March 11, 2021, authorized approximately $1.9 trillion in federal government spending. ARP is widely expected to boost economic growth over the next two to three years—and significantly so early on. The upswing in growth is likely to increase resource pressures and therefore consumer price inflation as well. The potential for this channel to raise inflation substantially has attracted the attention of economic commentators, including Olivier Blanchard and Lawrence Summers. But the magnitudes and persistence of the possible increases in ...

Constrained Discretion and Central Bank Transparency
We develop and estimate a general equilibrium model in which monetary policy can deviate from active inflation stabilization and agents face uncertainty about the nature of these deviations. When observing a deviation, agents conduct Bayesian learning to infer its likely duration. Under constrained discretion, only short deviations occur: Agents are confident about a prompt return to the active regime, macroeconomic uncertainty is low, welfare is high. However, if a deviation persists, agents? beliefs start drifting, uncertainty accelerates, and welfare declines. If the duration of the ...

Monetary and Fiscal Policies in Times of Large Debt: Unity is Strength
The Covid-19 pandemic found policymakers facing constraints on their ability to react to an exceptionally large negative shock. The current low interest rate environment limits the tools the central bank can use to stabilize the economy, while the large public debt curtails the efficacy of fiscal interventions by inducing expectations of costly fiscal adjustments. Against this background, we study the implications of a coordinated fiscal and monetary strategy aimed at creating a controlled rise of inflation to wear away a targeted fraction of debt. Under this coordinated strategy, the fiscal ...
