1) Pass-Through of Wages and Import Prices Has Increased in the Post-COVID Period

Annual CPI inflation reached 9.1 percent in June 2022, the highest reading since November 1981. The broad-based nature of the recent inflation readings has increased concerns that inflation may run above the Federal Reserve’s target for a longer period than anticipated. In this post we use detailed industry-level data to examine two prominent cost-push-based explanations for high inflation: rising import prices and higher labor costs. We find that the pass-through of wages and input prices to the U.S. Producer Price Index has grown during the pandemic. Both the large changes in these costs and a higher pass-through into domestic prices have contributed toward higher inflation.
2) How Much Did Supply Constraints Boost U.S. Inflation?
Julian di Giovanni

What factors are behind the recent inflation surge has been a huge topic of debate amongst academics and policymakers. We know that pandemic-related supply constraints such as labor shortages and supply chain bottlenecks have been key factors pushing inflation higher. These bottlenecks started with the pandemic (lockdowns, sick workers) and were made worse by the push arising from increased demand caused by very expansionary fiscal and monetary policy. Our analysis of the relative importance of supply-side versus demand-side factors finds 60 percent of U.S. inflation over the 2019-21 period was due to the jump in demand for goods while 40 percent owed to supply-side issues that magnified the impact of this higher demand.
