Accommodations with little or no marginal cost are cheaper per capita the more people use them, even if the marginal benefit to some of those people is lower than others. Accommodations with a high marginal cost are problematic when they're used by people for whom they provide a low marginal benefit.", "timestamp": "1469361663"}, {"author": "Jess", "source_link": "https://www.facebook.com/jefftk/posts/801270176022?comment_id=801270670032&reply_comment_id=801271463442", "anchor": "fb-801270670032_801271463442", "service": "fb", "text": "&rarr;&nbsp;Exactly. Another way to say this is that it depends on whether the goods are rivalrous or not.  Are there even examples of non-rivalrous handicap accommodations (like closed-captioning) that there is a norm against using?
