In economics, Friedman revived and developed the monetarist theory that the quantity of money in circulation is the main determinant of how economies perform. In his masterpiece A Monetary History of the United States, 1867-1960 (written with Anna Schwartz), he famously attributed recessions, including the Great Depression of the 1930’s, to a decline in the money supply.
在经济学中，弗里德曼重新恢复了货币主义者的理论并予以发扬光大。这一理论认为流通中的货币数量是各经济体表现的主要决定因素。在其与施瓦茨合著的杰作&lt;&lt;1867年至1960年的美国货币历史&gt;&gt;中，他将包括三十年代大萧条的经济衰退归结于货币供应的下降，从而声名远扬。同时，他认为，是货币供应过量造成了通货膨胀。
