同時，Rockefeller建立標準石油，壟斷美國90%以上的石油市場時，主動壓低價格與其他對手競爭，史料顯示，當時石油價格在其手上跌了將近8成。這證據顯經濟學的論證是正確的：高市占率不代表壟斷力（也就是無覓價能力），同時競爭最好最強的手段，永遠是價廉物美，一如Rockfeller曾寫信給合夥人說道：「Let the good work go on. We must ever remember we are refining oil for the poor man and he must have it cheap and good.」
克魯曼是個天才洋溢型的學者，一個在MIT經研所通過經濟學訓練出身的學者，在總體經濟與個體經濟都已相當紮實，否則連畢業都不可能，更遑論拿學 位。提到克魯曼，就不得不提到另一也廣為學術界以外所知的新興凱因斯學派大將Stiglitz，這兩位學者的立場都不為市場基要派的經濟學家所喜(以芝加 哥大學或芝加哥學派為主)，版主所列舉的經濟學家都是屬於這一派，也難怪他們多少有著酸葡萄的心理。
茲引現為聯準會主席，也是研究經濟大蕭條著稱的學者Bernanke名言：To understand the Great Depression is the Holy Grail of Macroeconomics. We do not yet have our hands on the Grail by any means。謙虛一點，總是好的，除非我們已經達到了諾貝爾經濟學獎的水準。
……We can be sure that economic analysis is being ignored when any of the following fallacious arguments are presented: that the rationale of the capitalistic system rests on a essential assumption of a “harmony of interests” ; that customers must take what producers offer them; that automation reduces available jobs; that tariffs protect domestic wage earners from foreign labor; that our otherwise unlimited productive capacity is curtailed by monopolistic capitalists who arbitrarily set prices high; that unions protect workers from greedy employers; that inflation hurts the wage earners and benefits the employer; that social-security payments contributed by employers to their employees are paid for by the employers; and that social conscience and civic sensitivity are or should be the main guides to business corporate behavior.
Just when he writes nasty individual comments that people forward.
Oh, well he wrote a series of posts saying he thought the World War II spending evidence was not good, for a variety of reasons, but I guess…
He said elsewhere that it was good and that it was what got us out of the depression. He just says whatever is convenient for his political argument. He doesn’t behave like an economist. And the guy has never done any work in Keynesian macroeconomics, which I actually did. He has never even done any work on that. His work is in trade stuff. He did excellent work, but it has nothing to do with what he’s writing about.
I’m not in a position to…
No, of course not.
I’m not in a position to know things like the degree to which Paul Krugman counts as a relevant expert on new Keynesian economics.
He hasn’t done any work on that. Greg Mankiw has worked in that area. ……
