I wish to thank the many loyal MR readers (buyers!) who pre-ordered my Discover Your Inner Economist: Use Incentives to Fall in Love, Survive Your Next Meeting, and Motivate Your Dentist.

Some of those profits are competed away by advertising, except in this case "the ad" is intended to provide real (not just persuasive) benefits to the consumers. Here are books and papers on efficient rent-seeking.
Addendum: I’ve now been adding new posts to it, but of course I can’t tell you their topics!
