WebTHEOREM: If the utility function is well behaved, it is separable iff two‐stage budgeting is justified. 3 PROOF: That separability justifies two‐stage budgeting is obvious: given the allocations m 1 , m 2 , . . . , m R to the groups, one obviously maximizes v r ( x r ) subject to p r · x r ≤ m r , each r , and this yields ( 1.1 ).
