We often encounter people who we believe are behaving immorally. We routinely try to change minds and often donate to charitable organizations that do the same. Of course, this does not always work. In a liberal, rights-based society, we have to tolerate this. But legal entitlements to act in ways that others find immoral are inefficiently allocated. For example, some meat-eaters value eating meat less than some vegetarians would be willing to pay them to stop. While many have written about (...) the limits of the market, market design, and abuse of right, few have considered the sale of these entitlements. This article proposes a market-based solution, encouraging the sale of these entitlements under certain conditions. This would lead to improvements both on an economic efficiency analysis and on a moral analysis. (shrink)
