|Greg Mankiw teaching|
Who is Greg Mankiw (pronounced "man q")? He is head of the economics department at Harvard University, former head of the Council of Economic Advisors to president George W. Bush, and author of the best-selling economics text books used in introductory economics classes in the U.S. He is also author of the popular Greg Mankiw's Blog.
Incidently, those interested in an introductory economics text would enjoy Mankiw's texts; BUT, unless you are made of money, I would recommend buying an older edition. The latest edition which is required at many colleges is pricey and the texts typically don't change a whole lot in moving to the latest edition. There are a number of inexpensive listings on eBay--just be sure to get a "Principles" text. Mankiw also writes some advanced texts for use in graduate courses.
