Can the decoy effect increase cooperation in networks? An experiment

General Economics 2025-10-07 v2 Economics

Abstract

This paper investigates whether the decoy effect - specifically the attraction effect - can foster cooperation in social networks. In a lab experiment, we show that introducing a dominated option increases the selection of the target choice, especially in early decisions. The effect is stronger in individual settings but persists in networks despite free-riding incentives, with variation depending on the decision-maker's strategic position.
