Query: Much ado about nothing.

This book was obviously written by non-mathematicians. An exercise in rigorous hand-waving. Rigor without mortis. Anybody who wants to become a mathematical economist would be better off by taking real math courses first. On the other hand, the Economics content is rather prosaic as is tradition in the Minnesota-Chicago school. There are a great many math and probability books out there that are more interesting, not to mention those that are more concerned about empirically relevant Economics. If you think Real Business Cycle models are mathematically rigorous and empirically relevant, well, this piece should become your Bible.
