I am reading an nice book on markets: Reinventing the Bazaar: The Natural History of Markets. The book is detailed look at how markets work and the role they can play in commerce. Each chapter takes some key aspect of market mechanics (e.g. the role of ownership, the role of information, etc) and explores it with examples taken from the real world. The examples are the best part, drawn from every corner of the world, markets big and small.
There is a slight bias in it, in favor of using free market mechanisms to solve the worlds problems. But its not overwhelming -- the book shows both sides of markets and spends a fair amount of time showing the imperfections of markets in gory detail.
I am about 2/3s through the book -- so far, I'd give it a strong recommendation.
