This work compares the economic systems of regions from free market to communism. Since the fall of the Soviet Union and the movement toward entrepreneurship in the remaining communist countries, this field of study has changed. This text concentrates on these movements and their implications.
It's a comprehensive overview of recent economic history around the world. I find myself referencing back to it frequently. I only gave it 4 stars (as opposed to 5) because I wish there was a more up-to-date edition.
