先前有網友建議我可以看看Krugman的東西。
在此之前，我只有在NYT上偶爾略略瀏覽Paul Krugman的專欄。之後，我的確花了一些心思比較認真地看，同時也注意了他在獲得Nobel獎之後的一些發言。
老實說，我相當不欣賞這位經濟學家，如果他現在還算是個經濟學家的話。
恰好看到一篇哈佛大學經濟系教授–Robert Barro的訪談，這位古典自由主義派經濟學家對於Paul Krugman的評論與我閱讀該人專欄後之感想十分契合。轉錄這位經濟系教授的訪談片段，供各位參考。
……Do you read Paul Krugman’s blog?
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. ……
