We study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents' confidence give rise to persistent liquidity trap episodes. There is no straightforward recipe for enhancing welfare in this economy. Raising the inflation target or appointing an...

We provide a quantitative theory of deflation and secular stagnation. In our lifecycle framework, an aging population puts persistent downward pressure on the price level, real interest rates, and output. A novel feature of our theory is that it also recognizes the reactions of government...

This article estimates the stance of fiscal policy using the framework of conditional forecasting to evaluate the stance in Brazil since 1997. This indicator is measured as the deviation of forecast of the output gap conditional to the observed values and steady-state values of the instruments...

This paper studies the design of optimal fiscal policy when a government that fully trusts the probability model of government expenditures faces a fearful public that forms pessimistic expectations. We identify two forces that shape our results. On the one hand, the government has an incentive...

This paper proposes a moment-matching method for approximating vector autoregressions by finite-state Markov chains. The Markov chain is constructed by targeting the conditional moments of the underlying continuous process. The proposed method is more robust to the number of discrete values and...

Does fiscal policy have qualitatively different effects on the economy in a liquidity trap? We analyze a nonlinear stochastic New Keynesian model and compare the true and loglinearized equilibria. Using the loglinearized equilibrium conditions, the answer to the above question is yes. However,...

How should public debt be managed when uncertainty about the business cycle is widespread and debt levels are high, as in the aftermath of the last financial crisis? This paper analyzes optimal fiscal policy with ambiguity aversion and endogenous government spending. We show that, without...

What is the policy uncertainty surrounding expiring taxes? How uncertain are the approvals of routine extensions of temporary tax policies? To answer these questions, I use event studies to measure cumulative abnormal returns (CARs) for firms that claimed the U.S. research and development (R&D)...

We build an infinite horizon equilibrium model of fiscal federation, where anticipation of transfers from the central government creates incentives for local governments to overborrow. Absent commitment, the central government over-transfers, which distorts the central-local distribution of...
