Main parts of the book and short summary:
Introduction:
The authors introduce the book, discussing the unconventional methods and ideas used to explore various social phenomena and question conventional wisdom.
Chapter 1 – “What Do Schoolteachers and Sumo Wrestlers Have in Common?”:
This chapter examines the role of incentives in driving human behavior, using the examples of cheating teachers and sumo wrestlers to illustrate how incentives can lead people to make unethical decisions.
Chapter 2 – “How is the Ku Klux Klan Like a Group of Real-Estate Agents?”:
This chapter explores the concept of information asymmetry, where one party has more information than the other, and how it can be used to manipulate people’s decisions. The authors use the example of the Ku Klux Klan and real estate agents to demonstrate this concept.
Chapter 3 – “Why Do Drug Dealers Still Live with Their Moms?”:
This chapter challenges the common belief that drug dealing is a lucrative and glamorous profession, and instead presents evidence that most drug dealers make very little money. The authors use an economic analysis to uncover the incentives and structures that keep drug dealers in the business.
Chapter 4 – “Where Have All the Criminals Gone?”:
This chapter looks at the sharp decline in crime rates in the 1990s and provides evidence that it was not due to increased police presence or stricter punishments but was mainly attributed to legalized abortion leading to fewer unwanted children growing up in disadvantaged households.
Chapter 5 – “What Makes a Perfect Parent?”:
The authors use data analysis to challenge popular beliefs about the impact of parenting on children’s success and suggest that it may not be as influential as many think.
Chapter 6 – “Perfect Parenting, Part II; or: Would a Roshanda by Any Other Name Smell as Sweet?”:
In this chapter, the authors continue to explore the impact of parenting on children’s success, discussing the relationship between a child’s name and their future success.
Chapter 7 – “The Sibling Effect”:
This chapter looks at the impact of birth order on children’s success, challenging conventional wisdom and providing evidence that second-born children may have a higher likelihood of engaging in risky behaviors.
Chapter 8 – “The Economics of Parenting, Part III”:
In the final chapter, the authors use an economic analysis to examine how parents can use incentives to motivate their children to succeed.
