Do higher interest rates add little disinflation while hindering supply investment?
Core argument: Pandemic-era sectoral supply constraints, demand shifts, and adjustment asymmetries were the primary drivers of price growth, so higher interest rates deliver minimal additional inflation reduction beyond what would have occurred anyway.
The pandemic gave rise to numerous sectoral supply constraints and demand shifts that – together with adjustment asymmetries – became the primary drivers of price growth. Any benefits from the extra interest-rate-driven reduction in inflation will be minimal compared to what would have happened anyway. Inflation already appears to be easing. It may be moderating more slowly than optimists hoped a year ago – before Russia’s war in Ukraine – but it is moderating nonetheless, and for the same reasons that optimists had outlined. Higher interest rates make it even more difficult to mobilize investments that could alleviate supply shortages.



















Brandon Adams Comment: “This is a great paper. I think the labor force participation rate could converge toward its pre-pandemic trend line faster than envisioned in this paper. The paper ignores asset markets altogether, and it seems clear to me that rapidly inflating retirement accounts in 2021 was a big part of this story. Towards the tail end of the time period covered in this paper, retirees met the unwelcome duo of rapidly decreasing asset prices and rapidly increasing consumer prices. This might or might not bring people in their 60s or 70s out of retirement, but it will almost surely slow the exit rate of those aged 40-60, and it might also bring back into the labor force some people in that age range who are currently sitting out.”
