pYes and no. Consumers don't need information in order to be suastantiblly causally responsible, though they may need info to be morally responsible. But even then, there's such a thing as culpable ignorance.In some cases, it's also a collective action problem. It might well be that everyone shopping at a new Walmart store hopes the ol' hardware store on the corner survives — but also wants low prices, and wishes everyone else would keep patronizing the ol' hardware store instead of them.Chris.]]>
