This book is one of several I had the pleasure to read on the theme of economics principles applied to everyday life.
The book includes a number of interesting, fresh perspectives for applying economic principles, such as how to motivate your dentist / family doctor (or any subject matter expert for that matter) in doing a good job in spite of the possibility to perform below standard while remaining undetected. I found quite a few of Cowen's recommendations surprising and counterintuitive.
Cowen is also honest in stating the limits of the various approaches he proposes.
As I am not much of an art lover, I did not fully appreciate the choice of art collection and consumption as an area for discussion.
I don't think Coven's book has the freshness and wit of Freakonomics or Tim Harford's Undercover Economist. Still a very enjoyable and recommended reading for those interested in this theme.
