Abstract
For qualitative probability spaces,monotone continuityandthird-order atom-swarmingare together sufficient for a unique countably additive probability measure representation that may have atoms (Mackenzie in Theor Econ 14:709-778, 2019). We provide a new proof by appealing to a theorem of Luce (Ann Math Stat 38:780-786, 1967), highlighting the usefulness of extensive measurement theory (Krantz et al. in Foundations of Measurement Volume I: Additive and Polynomial Representations. Academic Press, New York, 1971) for economists.
