拉姆齊問題

拉姆齊問題是政策制定者如何規範市場壟斷者指定價格政策，從而保證公眾利益的一個問題。該問題最初在1933年由J. Robinson陳述，但在這之前，1927年弗蘭克·普倫普頓·拉姆齊已經發現了這個結果，也因此以其名命名該問題。

Phase space graph (or phase diagram) of the Ramsey model. The blue line represents the dynamic adjustment (or saddle) path of the economy in which all the constraints present in the model are satisfied. It is a stable path of the dynamic system. The red lines represent dynamic paths which are ruled out by the transversality condition.
