This Essay offers a behavioral economic analysis of redistributive legal rules. Redistributive legal rules are rules chosen for their effects in shifting wealth from high-income to low-income individuals(progressive redistribution). The desirability of such rules has been the subject of intense debate within the legal community. Many law and economics scholars have urged that legal rules be chosen solely with an eye towards Kaldor-Hicks efficiency (which I will call simply efficiency for the remainder of this Essay); these scholars often urge that distributional considerations be addressed (if they are to be addressed at all) exclusively through the tax and welfare systems. On this view, distributive goals do not provide a basis for choosing an inefficient legal rule-although they might, it seems, provide a basis for choosing between two efficient rules. Other legal scholars have argued that the selection of legal rules should be informed by distributional considerations even at the expense of efficiency. I will calla rule redistributive if it makes such a trade-off between distributive objectives and efficiency
