(b) An economist seeking to predict the effect that an increase in a state's sales tax rate will have on consumers' purchases of goods and services resumes that people are limited in their ability to process information about how the sales-tax-rate increase will influence the after-tax prices those consumers will pay.

(c) To evaluate the impact of an increase in the range of choices that an individual confronts when deciding among devices for accessing the Internet, an economic researcher makes the assumption that the individual is unable to take into account every new Internet-access option available to her.
