Arrow's Impossibility Theorem may be strengthened by replacing the conditio
Arrow's Impossibility Theorem may be strengthened by replacing the conditions of montonicity and citizen sovereignty with this. A similar theory by Kaldor and Hicks adds hypothetical compensation to this situation. One may graphically represent a set of situations that share this characteristic as an eponymous "frontier." It does not imply equity and, in an exchange-based economy, this state may be reached when competitive equilibrium is present. For 10 points, identify this important economic concept named after an Italian thinker who wrote Mind and Society; a concept which denotes an allocation to which no improvements can be made without marginal cost.
