货币主义

货币主义（Monetarism），又称重货币学派、货币学派，是1960年代形成的经济学流派，以挑战凯恩斯主义的面貌出现。其领袖人物为米尔顿·傅利曼，他在1976年10月获得诺贝尔经济学奖。货币经济学认为货币的供应量在短期内对国家的产出、在长期上对物价水准都有巨大的影响。这种货币政策的目标是透过增加货币的供应量来实行。
货币主义的核心命题是：在经济活动中，货币扮演着最重要的角色，通货膨胀的原因就是发行过多货币。政府的角色是透过中央银行，调控在经济体中流通的货币数量，除此之外，不需要干预经济活动。

**理论**
货币主义源起于米尔顿·傅利曼与安娜·施瓦茨合著的《A Monetary History of the United States》，并指出“通货膨胀永远是无处不在的货币现象。”他批评美国政府当时采用的凯因斯主义和约翰·梅纳德·凯因斯基于政府干预的理论。他长期批评美国联邦准备理事会在货币政策，认为美联储的货币紧缩政策是大萧条的主要原因，而发行过多货币造成了70年代的通货膨胀。弗里德曼赞成中央银行透过统计国家生产力的状况和需求，来订定让货币供需平衡的货币政策。
米尔顿·傅利曼认为：「通货膨胀在任何时间、任何地点都是因为发行过多货币。」所谓“结构性通胀”、“输入型通胀”都是无稽之谈。中央银行的货币发行过多则造成通货膨胀，过少则造成通货紧缩。货币主义认为，在短期，货币供给的变动虽然能够影响实际经济状况，例如就业；但在长期，它能影响到的只有通货膨胀。主张货币发行量的成长率要保持一个固定的速度，让经济中的个体对通货膨胀有完全的预期能力，这种货币机制被称为弗里德曼规则。

**历史**
货币主义在提出之初并不受重视，直到柴契尔夫人在英国采用货币主义政策，使英国经济成功复苏，货币主义政策开始受到各国重视，使得各国中央银行政策逐渐偏向货币主义，取代凯恩斯主义的地位。
