“…Our paper is also linked to the extensive literature on bargaining experiments, particularly, ultimatum and dictator game experiments (see, e.g., [32,33]; for an overview of the experimental results of these games see [34]). Experimental investigations of these games have been guiding the analysis of other-regarding preferences since the beginning of this literature (see, e.g., [35,36]; for more recent contributions see, e.g., [37,38]). Typically, this literature focuses on the type and the intensity of individual other-regarding preferences that can be concluded from the experimental results of these games.…”
