In the past Mankiw was involved in teaching Social Analysis 10. He said that the organizational structure of the course influenced him deeply when he was writing the book.

Martin S. Feldstein, Baker professor of economics, who teaches Social Analysis 10, could not be reached for comment.

Caitrin E. Moran '00, who is taking the course, said that she was pleased with the textbook, which is the primary textbook assigned in the class.

"I think it's very straightforward and explains things clearly," Moran said. "I like the fact that it's concise and doesn't ramble on."

However, other students using the book said that the textbook complemented the course too much.

"It's too easy," said a student in the economics department who asked not to be identified. "I was hoping for some more information in the book, not just the same thing that's covered in class."

However, teaching fellows said that the compatibility between the textbook and the course work would benefit students.

"It's great so far," said Robert Bruce, a teaching fellow in the class. "I think the students have been able to tie together the textbook with section work in a more efficient manner than before."

Mankiw said that the huge advance has not changed him.

"In terms of the advance, it's nice to have the cash. But it hasn't had a large impact in my lifestyle," Mankiw said. "I live in the same house I've lived in for 10 years. I drive the same car. I did buy my wife a minivan, but that has to do with the children needing it."
