Here is an opinion, but not on the topic you asked about:
I have stumbled upon your blog a couple times, and I must say that I am very much put off by it. The blogosphere is fill with too much rude ad hominem rhetoric. Engaging in it under a pen name seems particularly cowardly. I recommend having the courage of your convictions by revealing your name. Otherwise, stop the mean-spiritied attacks on Larry Summers and other economists of note.
To which I responded:
One unsolicited opinion deserves another:
I have stumbled upon your blog a couple times, and have seen your writings, including a speech you gave as President Bush's CEA Chair, and I must say that I am very put off by it. The world is filled with too many conservative white male economists detached from the real world who give horrifically bad economic advice, sell overpriced and low-quality textbooks, and are accountable to no one. Removing the comment section from your blog seems particularly cowardly, you should be ashamed to charge $178.50 for your textbook, and calling tax cuts for the rich and social security privatization "deficit reduction strategies" in your speech as CEA chair was tantamount to prostitution. I recommend having the courage of your convictions by restoring your comment section, cutting the price of your textbook in half, denouncing the failed positions you took in the Bush Administration, and calling the Fed out on its misguided policies over the past year and a half, which continue to affect millions of people.
P.S. The course I am TA'ing for next quarter will be using your favorite textbook, and so I'm going to blog the course and review your book, which I haven't seen yet. I won't be pulling any punches, but I will also take your advice and refrain from cheap shots. If you wanted to be non-ideological about it, you could actually use my review to make future editions of your text better.
What creeps me out is why he wants to know my name? I explained pretty clearly that I'm a grad student blogger. He wouldn't recognize my name anyway. WTF?
