Using global case studies from the Participedia database, the findings reveal that democratic innovations excel in various attributes but rarely deliver substantial redistributive impact.

This paper introduces the Participatory Decommodification Index (PDI), a framework that uses AI for assessing whether democratic innovations reduce individuals’ reliance on market systems. Building on Esping-Andersen’s (1990) decommodification theory, designed initially to compare welfare regimes, this study adapts the concept to participatory and deliberative processes that aim to redistribute power and resources. The PDI evaluates democratic innovations across five dimensions: accessibility, democratic control, institutional stability, redistributive impact, and deliberative quality. Using global case studies from the Participedia database, the findings reveal that democratic innovations excel in various attributes but rarely deliver substantial redistributive impact. The PDI provides a critical lens for assessing how democratic practices can challenge commodification in capitalist democracies. This approach calls for re-centring material justice within democratic innovation and provides a diagnostic tool for scholars, practitioners, and policymakers seeking structural transformation beyond symbolic participation.
