Whos afraid of aggregating money metrics?

We provide an axiomatic justification to aggregate money metrics. The key axiom requires the approval of richer-to-poorer transfers that preserve the overall efficiency of the distribution. This transfer principle-together with the basic axioms of anonymity, continuity, monotonicity, and a version of welfarism-characterizes a standard social welfare function defined over money metric utilities.
