They found, for example, that the unusually shaped Toyota Prius hybrid was a conspicuous badge that sold better in “green” communities than in other communities, all things being equal. “Consumers are willing to pay up to several thousand dollars to signal their environmental bona fides through their car choice,” wrote Sexton and Sexton.
