The Monkey Cage’s Lee points to an article, Psychology and Experimental Economics: A Gap in Abstraction (unfortunately gated), that discusses the differences between how experimental psychology and experimental economics approach the same phenomena and how the two fields might converge.
The paper is short but quite interesting, and it covers some experimental research on altruism and on gender discrimination.
Strangely, the authors twice refer to utility maximization as a normative theory not a positive theory.
For economists, these elements are derived from their general normative theory—that behavior is driven by utility maximization.
I thought that was odd.
