Van Leeuwen, Boris and Alger, Ingela (2024) Estimating Social Preferences and Kantian Morality in Strategic Interactions. Journal of Political Economy Microeconomics, vol. 2 (n° 4).

Abstract

Theory suggests that a form of Kantian morality has evolutionary foundations. To investigate the relative importance of Kantian morality and social preferences, we run a laboratory experiment on strategic interaction in social dilemmas. We structurally estimate social preferences and Kantian morality at the individual and aggregate level. We observe considerable heterogeneity in preferences. Finite mixture analyses show that the subject pool is well described as consisting of two or three types: all display a Kantian moral concern, which they combine with aheadness aversion, behindness aversion, or both. The value of adding Kantian morality to well-established preference classes (distributional preferences as well as reciprocity) is also evaluated.
