Behavioral Economic Phenomena in Decision-Making for Others

Publication date: Available online 8 June 2019Source: Journal of Economic PsychologyAuthor(s): John Ifcher, Homa ZarghameeAbstractWe examine whether biases identified in the behavioral-economics literature apply in decision-making for others (DMfO). We conduct a laboratory experiment in which subjects make decisions on behalf of themselves and others in eighteen tasks that measure the following biases: present-bias in time preferences, reflection effect in risk preferences, compound risk aversion, decoy effect, anchoring bias, endowment effect, and identifiable-victim bias. In our experiment, DMfO is DMfO simpliciter: unincentivized decisions made by one individual on behalf of another--the individual making decisions faces no direct costs or benefits when engaging in DMfO (as they would in a principal-agent framework or with bequest motives), and DMfO is not framed as giving advice or guessing others’ behavior. Although we find that DMfO is by and large statistically indistinguishable from decisions for oneself, we identify the following self-other discrepancies: (i) willingness to pay (i.e., bids to procure goods and donations to charity) is higher in DMfO than in decisions for oneself in tasks associated with the anchoring bias, endowment effect, and identifiable-victim bias; and (ii) the propensity to give uninterpretable responses is higher in DMfO than in decisions for oneself. We also find order effects, with DMfO more similar to decisions for oneself when DMfO follo...
