IZA DP No. 18409: Basic Needs Satisfaction as a Fundamental Distributive Principle: Evidence from the Lab and the Field

Thomas Dohmen, Frauke Meyer, Gari Walkowitz

This paper provides clear evidence that concerns for basic needs satisfaction (BNS) represent a distinct distributional motive. Using a unified theoretical and experimental framework across five dictator-game experiments in Germany and Georgia (N=446), we disentangle BNS from motives such as maximin, selfishness, efficiency, generosity, and envy. A substantial share of participants displayed BNS-driven choices and were willing to forgo income and efficiency to satisfy others’ basic needs. BNS remained robust across contexts, incentive schemes, and countries, and increased when needs satisfaction had strategic relevance. The results highlight the importance of BNS for understanding distributional preferences and policy design.
