Abstract

We extend the mixed-motives model of transfer derivatives developed by Cox et al (2004) introducing subjectively-assessed recipient need in place of an absolute income threshold at which the donor’s dominant motive switches from altruism to exchange. This refinement provides a theoretically justifiable threshold amenable to empirical measurement. We test the extended model with customized survey data from Tonga and find evidence consistent with Cox et al in support of altruism for households below the threshold, but, we also find a positive, exchange-motivated relationship for those above the threshold. We conclude that either crowding-out or crowding-in of private transfers can occur when the recipient’s welfare improves, depending on the household’s pre-transfer welfare level. This also has implications for the distributional impact of private transfers and could explain why poverty reduction can be accompanied by increased income inequality.
