"An assessment of the mating motive explanation of the beauty premium in market-based settings", Behavioral and Brain Sciences
Labor market and real-life studies were not designed to discriminate between evolutionary and taste-based and stereotype explanations for the beauty premium, have too many confounding effects, and lack crucial information. Smaller-stake and experimental studies provide more compelling evidence in favor of mating motives and suggest the direction of future research for the economists' field studies.
