3. Experts’ “Informational Advantages”
Criminologists
travel agents
car salespeople & Saturn cars
physicians & tonsillectomies/cesarean-section rates

real-estate agents & the standard 6% commission: $300,000 home = $4,500 (or 1.5%) after splitting with the other buyer or seller and their agency;
holding out for an additional $10,000 = ?

4. Fundamental Ideas 1.) incentives are the cornerstone of life
2.) conventional wisdom is often wrong
3.) dramatic effects often have distant, even subtle causes
4.) “experts” use their information advantages to serve their own agenda
5.) knowing what to measure, and how to measure it, makes the world a lot less complicated (think empirically)

10. Incentives: Day Care & Prostitution
An incentive (negative or positive) is simply a means of urging people to do more of a good thing and less of a bad thing.
Three basic flavors: (1) economic, (2) social, and (3) moral
Economic: day care center in Haifa, Israel and fining tardy parents.
After the $3 fine went into effect, the number of late child pickups promptly went…? Also, $3-per-pack “sin tax” for cigarettes.
Social: banning of cigarettes in restaurants, prostitution busts
Moral: parental guilt over late child pick-ups at day care center

11. Moral/Social Incentives and Modern Life

12. Economic Incentives and Modern Life
- Australian prison ships in the early 1900s
- April 15, 1987 and the disappearance of
of 7 million American children
- frequent flyer miles (“loyalty programs”)

13. Incentives & Cheating Teachers cheating and “high stakes” testing:
- How did the teachers cheat?
- How was their cheating discovered?
- How did administrators confirm their discovery?
Do Sumo wrestlers cheat?
- When? Why? 15 bouts per tournament and
7-7 wrestlers

14. Cheating and the “Bagel Man”
Paul F.’s bagel business is essentially an “honor-system commerce scheme”
Not paying for a bagel (or doughnut) is a form of white-collar crime, for which it is much harder to collect data than street crime. Why?
In his own research business, payment rates averaged 95%

15. What the Bagel Man Saw
Payment rate among all of his clients is approximately 87-89%
87% before 9/11 (89% after; 15% reduction in theft)
What has Paul F. learned about honesty?

16. What the Bagel Man Saw Telecoms companies and law firms?
Executives vs. administrative workers?
Places where security clearance was required?
Two great predictors of a company’s honesty?

17. What the Bagel Man Saw
Relationship between payment rates and local unemployment rate?
Effect of weather?
High-cheating holidays vs. Low-cheating holidays?
Paul F.’s sobering belief: “Honest people are honest, and cheaters will cheat regardless of the circumstance.”
Based on his data, is that accurate?
