Searching for Hysteresis
We search for the presence of hysteresis, which we dene as aggregate demand shocks that have a permanent impact on real GDP, in the U.S., the Euro Area, and the U.K. Working with cointegrated structural VARs, we nd essentially no evidence of such effects. Within a Classical statistical framework, it is virtually impossible to detect such shocks. Within a Bayesian context, the presence of these shocks can be mechanically imposed upon the data. However, unless a researcher is willing to impose the restriction that the sign of their long-run impact on GDP is the same for all draws, which amounts ...

Untangling Persistent versus Transitory Shocks to Inflation
How much persistent versus transitory forces contribute to inflation influences the Federal Reserve’s ability to achieve its goal of 2% average inflation over time. If elevated inflation is driven mainly by persistent shocks, then a stronger and longer-lasting policy response is likely to be needed to bring inflation back down. Recent data show that consecutive changes in monthly inflation rates have tended to move increasingly in the same direction. This pattern suggests that the contribution of persistent shocks to inflation has been rising since mid-2019.
