Description:  "Minimal Liberty" is incompatible with Pareto optimality. The liberal paradox, also Sen paradox or Sen's paradox, is a logical paradox discovered by Amartya Sen which purports to show that no social system can simultaneously 1 be committed to a minimal sense of freedom, 2 always result in a type of economic efficiency known as Pareto efficiency, and 3 be capable of functioning in any society whatsoever.
