主题：Selling to Consumers with Intransitive Indiﬀerence
We are indiﬀerent between two cups of coﬀee when one diﬀers from the other in having only one more grain of sugar. But such an indiﬀerence is not transitive, because eventually, after many enough grains of sugar are added, we will become able to tell one cup is sweeter than the other. When consumers feature intransitive indiﬀerence, putting a bad deal along side a good deal can boost the sale of the latter by helping consumers to better appreciate it. When sellers compete for these consumers, they tend not to undercut each other, because undercutting often go un-appreciated. Instead, sellers segregate into providers of good deals and bad deals, with the formers free-ridingon the latters in helping consumers better appreciate their good deals, and the latters free-riding on the formers in making consumers less hesitant to buy.
