AI automation and augmentation pose central bank stabilization challenges
A Bank of Canada working paper published in July 2026 examines how AI augmentation and automation create short-term monetary policy stabilization challenges in a two-speed economy. The study shows that sector-specific AI adoption opens a sectoral wedge between labor markets.
Two-speed economy complicates rate decisions
Bank of Canada researchers Joshua Brault, Maryam Haghighi, and Jing Yang study the monetary policy response to AI adoption using a two-sector New Keynesian model with sticky prices and downward nominal wage rigidity.
The study distinguishes between augmentation, which raises labor productivity within existing tasks, and automation, which displaces labor by reallocating tasks to machines.
In the short run, both shocks lower labor demand on net.
Because monetary policy operates through aggregate demand and cannot differentially target sectors, accommodation that reduces unemployment in the AI-affected sector raises inflationary pressure in the unaffected one, opening a sectoral wedge between the policy rates required to clear the two labor markets.
Augmentation versus automation
For output-equivalent shocks, automation generates a larger decline in labor demand and a systematically wider sectoral wedge than augmentation, pushing its Phillips curve above and to the right.
Consequently, restoring full employment comes at a greater inflationary cost under automation, requiring a rate cut of 3.34 percentage points compared to 1.48 percentage points for augmentation.
Furthermore, while broad augmentation allows falling sectoral prices to offset aggregate inflation signals, automation drives up prices across both sectors.
Fixing employment risks delaying structural change
The working paper delivers a sharp reminder that monetary accommodation is a blunt tool for structural shocks.
Sustaining employment in the short run through monetary stimulus can postpone necessary long-term economic adjustments.
Central banks risk treating structural displacement as a simple demand deficiency.
