Does Cooperation Deter Children from Waste or Inequity? a Developmental Study

This study investigates how age, cooperation, and waste avoidance influence children’s advantageous inequity aversion (AIA) in Türkiye. Using a 2×2×3 experimental design with 407 children aged 4–10, results showed that non-waste condition and cooperative context increased AIA, particularly in older children (9-10 years), reflecting sociocultural influences on fairness development.
