 Specialists of welfare economics once claimed that Arrow’s result had no bearing on economic allocation (e.g. Samuelson 1967), and there is some ambiguity in Arrow (1951) about whether, in an economic context, the best application of the theorem is about individual self-centered tastes over personal consumptions, in which case it is indeed relevant to welfare economics, or about individual ethical values about general allocations. It is now generally considered that the formal framework of social choice can sensibly be applied to the Bergson-Samuelson problem of ranking allocations on the basis of individual tastes. Applications of Arrow’s theorem to various economic contexts have been made (see the surveys by Le Breton 1997, Le Breton and Weymark 2011).
