supply side economics; supply-side economics 供給面經濟學

閱讀筆記：

每種學派都有本身重要的見解，巨波投資人可以用來磨銳自己對金融市場的看法。比方說，古典經濟學告訴我們，經濟和市場如何進行自然調節，凱因斯經濟學則說明在哪些狀況下，那些調節不可能發生。同樣的，貨幣學派揭露貨幣和價格之間十分重要的連結關係，供給面經濟學則說明經濟體如何能夠運用減稅和自由化等工具促進成長，卻不必擔心通貨膨脹復熾。當然了，新古典經濟學大談預期心理在股票市場和總體經濟中扮演的角色。

諾貝爾經濟學獎得主保羅．克魯曼（Paul Krugman）寫的《面對失靈的年代：克魯曼談金融海嘯》（The Return of Depression Economics and the Crisis of 2008）一書，抨擊供給面經濟學：

The specific set of foolish ideas that has laid claim to the name “supply-side economics” is a crank doctrine that would have had little influence if it did not appeal to the prejudices of editors and wealthy men. But over the past few decades there has been a steady drift in emphasis in economic thinking away from the demand side to the supply side of the economy.
