ニクソン・ショック
Lietaer's post-graduate thesis published in 1971 included a description of "floating exchanges". The Nixon Shock of that same year eradicated the Bretton Woods system by unhinging the US dollar value from its gold standard and inaugurated an era of "universal floating exchanges" (prior to that time the only "floating exchanges" involved some Latin American currencies) Litaer's thesis attracted the financial world's attention.
