This study examines the framing effect of relative proportion versus absolute amount in income allocation in ultimatum game. The hypothesis is that both absolute amount and proportion matter in allocation decisions, but they are weighted differently according to total endowment and allocation methods. We design an ultimatum game experiment conducted using the WeChat platform where two people allocate a given endowment between them. Participants are randomly divided into two treatment groups and three different endowment levels. In the control group, allocation proposal between a pair is measured in absolute amount. In the treatment group, allocation proposal is indicated as a proportion of their total endowment. We examine in the ultimatum game how proposers’ offer decisions and receivers’ acceptance decisions are affected by the proposal treatment and endowment levels. We find that the proportion treatment increases average proposed offer. In particular, proposed amount is increased by the treatment in the high endowment condition, not in the medium and high endowment conditions. The treatment may enhance participants’ awareness of fair sharing. These findings have important implications for many cases of income distribution such as wage allocation, public good contribution, and tax distribution.
