BERKELEY – The central insight of macroeconomics is a fact that was known to John Stuart Mill in the first third of the nineteenth century: there can be a large gap between supply and demand for pretty much all currently produced goods and services and types of labor if there is an equally large excess demand for financial assets. And this fundamental fact is a source of big trouble.
发自伯克利——英国经济学家约翰·斯图亚特·穆勒（John Stuart Mill）早在十九世纪初就道出了宏观经济的核心本质：一旦社会产生对金融资产的庞大需求，那么市面上几乎所有商品，服务和劳动力的供需都会由此产生巨大缺口，而这一基本事实则是大灾难的根源。
