Most of the economics can be summarized in four words "People respond to Incentives".. This is how Landsburg commence this book which is full of bizarre riddles, solved by not so common economics principles.
The books take you on the journey where every chapter is like a riddle which compels you to think and exhaust your brain to the core. Landsburg basic premise is that "things and situations which look simple are actually much more complicated in reality."
However, on various fronts I disagree with his findings which seemed ludicrous and too impractical (specially his anti-environmental approach)
