Zeroization

R. Preston McAfee, who teaches at Caltech has already had a pretty extensive and busy career, so I don’t know how exactly he found the time to author a textbook as well. His book, Introductory Economics is quite good and is an excellent reference even for those who already have a basic background in economics. In addition to the “principles” these textbook also contains intermediate microeconomics material. He’s made it available for free as a PDF download and will sell you a printed version for only $11.60. That’s way more reasonable than any of the other commercially available textbooks I’ve seen. McAfee’s book is also broader in coverage and includes many topics related to business strategy (another one of his interests.)
