Ours and yours, forget about the theory of tax incidence. Just type in /marginalrevol-20 after any Amazon link, and we get a small chunk of the proceeds. Alternatively, go to the Amazon box on the right side of this blog, just above the site meter. It costs you nothing, and we thank you in advance.
We do get some review copies, but most of the books we cover we buy with our own money. The small extra income we get from Amazon referrals allows us to buy many more and give you a better sense of what is going on in the world of ideas. I do collect CDs, but not books, which I treat as a burden. If you are wondering, most of the books reviewed end up donated to the Harper Library at The Institute for Humane Studies, itself a worthy cause.
