Jevons Paradox and the Myth of Resource Efficiency Improvements
Abstract
William Stanley Jevons observed in 1865 that improvements in coal-burning efficiency led to increased, not decreased, total coal consumption. This book provides a comprehensive, multi-disciplinary treatment of the Jevons Paradox, demonstrating that efficiency improvements in resource use frequently lead to increased total consumption rather than conservation.
★ Curator Summary
Jevons Paradox is the theoretical backbone of second-order effects in workforce planning. Jevons showed in 1865 that making steam engines more efficient didn't reduce coal consumption — it increased it by making coal-powered work cheaper and more accessible. The same mechanism operates when AI makes customer service 'cheaper' (less effort, less wait): total demand for service increases. This book is the definitive multi-disciplinary treatment, drawing from energy economics, ecological economics, and technology studies.
Why It Matters
Every WFM practitioner needs to understand Jevons Paradox because it explains the gap between projected and realized AI savings. When you make it easier and faster to get help, customers contact you more — not less. The 20% effective volume growth we model in the FOW-Value three-pool architecture comes directly from this mechanism. Planning that ignores Jevons will systematically understaff by 15-25%.
Caveats
Jevons Paradox is well-established in energy economics but less empirically validated in service operations specifically. The magnitude of the effect varies significantly by context. Not all efficiency improvements trigger full rebound — partial rebound (30-70%) is more common at the micro level. The macro-level 'backfire' scenario (>100% rebound) is debated.
