This public visibility:
Many things contributed to making Livestrong
bands a success. They cost only a dollar, making it easy for people to try out being part of the movement, even if they weren’t sure they wanted to commit themselves. The wristbands were also really easy to wear. Unlike breast cancer ribbons, which you have to pin on different pieces of clothing, Livestrong bands could be worn all the time. You could wear one all day, keep it on while sleeping, even wear it in the shower. You never had to take it off or remember where you left it. But color also played an important role, as discussed.

Kahneman received the Nobel:
For a popular treatment of prospect theory, see Kahneman’s book
Thinking, Fast and Slow
(2011), from Farrar, Straus and Giroux. For a more academic treatment, see Kahneman, Daniel, and Amos Tversky (1979), “Prospect Theory: An Analysis of Decision Under Risk,”
Econometrica
47 (1979), 263–91. Many of the scenarios discussed in this chapter are adapted from Richard Thaler’s work on mental accounting. See Thaler, Richard (1980), “Toward a Positive Theory of Consumer Choice,”
Journal of Economic Behavior and Organization
1, 39–60;
and Thaler, Richard (1985), “Mental Accounting and Consumer Choice,”

While noting something is on sale:
A good deal of research has examined how saying something is on sale affects perceived value. For examples, see Blattberg, Robert, Richard A. Briesch, and Edward J. Fox (1995), “How Promotions Work,”

14, no. 3, 122–32; Lattin, James M., and Randolph E. Bucklin (1989), “Reference Effects of Price and Promotion on Brand Choice Behavior,”

Marketing Science
11, no. 3, 207–20. For an empirical investigation of how sale signs affect purchase, see Anderson and Simester, “Are Sale Signs Less Effective,” 121–42.

For evidence on how restrictions on who can get access to a deal affect perceived value, see Schindler, Robert M. (1998), “Consequences of Perceiving Oneself as Responsible for Obtaining a Discount: Evidence for Smart-Shopper Feelings,”
Journal of Consumer Psychology
7, no. 4, 371–92.
whether a discount seems larger:
