Megan McArdle

I mentioned Megan McArdle when I recommended a bloggingheads episode. Remarkably, her blog "Asymmetrical Information" at The Atlantic magazine's website is a constant source of powerful insights. She is at her best when pundits make silly assumptions, flawed arguments, or forget about Econ 101 principles. Her arguments are sharp and ruthless, leaving her opponents usually like a spanked child. See examples here, here, and here. She is also helpful when shedding light on the cost of policies such as health care reform. Last but not least, she is a superb writer who can explain complex arguments with clear grammar and logical arguments, though sometimes she employs an unnecessary number of words to make a point.
