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

This paper presents empirical evidence on the nature of idiosyncratic shocks to firms and discusses its role for firm behavior and aggregate fluctuations. We document that firm-level sales and productivity are hit by heavy-tailed shocks and follow a nonlinear stochastic process, thus departing...

Using a New Keynesian Phillips curve, we document the rapid and persistent increase in the natural rate of unemployment, ut*, in the aftermath of the pandemic and characterize its implications for inflation dynamics. While the bulk of the inflation surge is attributed to temporary supply...

In recent years, the concurrent occurrences of the COVID-19 pandemic and the Russian invasion of Ukraine have led to global disruptions in supply chains and a surge in commodity prices. Major advanced economies have experienced an increase in inflation rates and a decline in economic activity....

We discuss the concept of core inflation and its relevance for policymakers and then review a variety of approaches that have been pursued for the construction of informative core measures. After illustrating some empirical patterns displayed by U.S. inflation data and discussing conceptual...

We show that in the formalization of representativeness (Kahneman and Tversky (1972)) developed by Gennaioli and Shleifer (2010), overreaction and confidence are affected by uncertainty, as a news effect interacts with an uncertainty effect. In the time series domain, this interaction emerges in...

The Central Banks use diffusion indexes (DIs) to synthesize information from proprietary surveys that complement official statistics generating real-time proxies of the economically relevant variables. According to the evidence, the DIs closely follow the economic cycle reflected in those...

This paper documents the recent changes in the structure and estimation procedures of the SAMBA model, providing a complete description of the decision problems that each economic agent faces, the first order conditions that solve those problems, and the new techniques employed to estimate the...
