The rebound mechanism
Jevons paradox describes cases where efficiency reduces the resource required per unit but expanded use increases total consumption. In digital markets, the mechanism can be powerful because distribution is global and the marginal cost of another analysis, design or software interaction is low.
What expansion could look like
A service once reserved for major companies may become affordable to small firms. A report produced annually may become a live dashboard. A customer may receive a personalised explanation rather than a standard brochure. Each unit requires less labour, yet the number of useful units grows.
Evidence points to augmentation as well as substitution
The World Economic Forum’s 2025 employer survey anticipates both job creation and displacement, while the NBER customer-support study shows workers using AI to handle work more productively. Neither proves that every market expands. They show why business planning should consider new demand, not only cost removal.
Plan for three scenarios
Model substitution, expansion and a mixed case. Ask how price elasticity, trust, regulation and customer acquisition constrain demand. If AI makes delivery ten times cheaper, can the business reach customers who were previously uneconomic? Can it create a new recurring service? The most valuable strategy may be market creation rather than headcount reduction.
