Zero-sum：特朗普的全球貨幣政策是零和做法

隨著中美貿易戰進一步升級，美國宣布中國為匯率操縱國和人民幣破7讓投資者看到一場貨幣戰爭的可能性。如果美國陷入貨幣戰爭，會有什麼風險？

時報“結語“專欄指出，國際經濟學家的傳統觀點是，人民幣貶值不能算作匯率操縱。但特朗普在全球貨幣政策上受到零和思維影響，進而採取相關措施(a zero-sum approach)，違反了世界經濟政策制定者的共識，這可能會削弱美國在國際金融體系中發揮的核心作用。

Zero-sum意為“零和”，是博弈論中的一個概念。這種概念認為，利益相關各方的利益總和是恆定的；如果一方得到利益，則必有另一方的利益受損。譬如冷戰就被認為是一場零和博弈，當時美國和蘇聯都抱有一種“相互保證毀滅”的核戰略。這種思維延續至今，甚至可能引發一場新的全球軍備競賽 。
