We show that TFP reacts counter-cyclically to macroeconomic shocks, which we identify by imposing sign restrictions. Counterfactual simulations, based on a New Keynesian DSGE model, show that firms manage to employ labor more efficiently during downturns, which leads to a muted drop in the...

We study monetary policy at the ZLB in a traceable three-period model, in which price-level targeting emerges endogenously in the welfare function. We characterize optimal price-level forward guidance under discretion and commitment. Potentially non-monotonic discretionary welfare losses are...

In this paper we present a simple framework to model central bank forward guidance in a liquidity trap. We analyze the role of long-run and short-run price stickiness under discretion and commitment in a straightforward and intuitive way. Despite the impact of price rigidity on welfare being...

This paper finds that labor tax cut can be an effective policy tool to mitigate the negative effects of a shock that made the zero lower bound on the nominal interest rate binding if the economy features rule-of-thumb households (besides Ricardian ones) and nominal rigidities in prices and...

Concerns of prolonged stagnation periods with near-zero interest rates and deflation have become widespread in many advanced economies. We build a theoretical framework that rationalizes two theories of low interest rates: expectations-trap and secular stagnation in a unified setting. We...
