"Mr. Thompson, Thanks for your e-mail. You critically observe that on my blog I 'seldom rise above Econ 101.' You’re correct, but my focus on economic fundamentals is by design.
I wholeheartedly agree that knowledge of advanced economics is valuable. But the economic knowledge ignored by the public, pundits, and politicians isn’t that which is found in ECON 999 but, instead, that which is found in ECON 101."
