8. Off the Books: The Underground Economy of the Urban Poor by Sudhir Alladi Venkatesh.
This book studies one neighborhood in Chicago over a number of years examining the underground economy and its effects both positive and negative. It ranges from legal stuff that isn’t reported to the government such as car repair and hair cutting to illegal activities such as prostitution and drug sales. It also examines the participants involved in some way in these activities ranging from gang members to pastors.
I give it a 7 out of 10.
