Things I admire about Mankiw's Macroeconomics...

First and most important is the overwhelming clarity of this book. Mankiw is better than anyone else at writing crystal-clear descriptions of economic concepts. There are times when I think that Mankiw can make any economic concept--at least, the gist of any economic concept--accessible to anyone. (Of course, there is a flip side to clarity: sometimes, in my view at least, Mankiw makes concepts clearer than the truth.)
