In the quasilinear case, surplus maximization leads to constrained efficient Drèze equilibria. We investigate the question of whether surplus maximization can be useful beyond the quasilinear case. We use two different surplus concepts, the equivalent and the compensating surplus. The first one...

Consider an economy with one public enterprise that is subject to a budgetary constraint and charges prices according to the first-order necessary conditions suggested by M. Boiteux (1956) or F. P. Ramsey (1927). The authors state conditions sufficient to ensure that the resulting allocation is...
