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 # be committed to a minimal sense of freedom, # always result in a type of economic efficiency known as Pareto efficiency, and # be capable of functioning in any society whatsoever. This paradox is contentious because it appears to contradict the classical liberal claim that markets are both efficient and respect individual freedoms. If, as Sen claims, classical liberalism means Pareto efficiency by the word efficiency, there is a paradox, then this liberal claim cannot be true. The paradox is similar in many respects to Arrow's impossibility theorem and uses similar mathematical techniques. ==Pareto efficiency== (詳細はウィキペディア(Wikipedia)』 ■ウィキペディアで「Liberal paradox」の詳細全文を読む スポンサード リンク
