%X Este artigo pretende escrutinar os pressupostos te¨®ricos e as implica  es pr¨¢ticas da an¨¢lise custo-benef¨ªcio (ACB), actualmente um dos mais influentes e controversos instrumentos de avalia  o das pol¨ªticas p¨²blicas proposto pela ci¨ºncia econ¨®mica. O ponto de partida ¨¦ o que designamos por nexo comensurabilidade-mercadoriza  o que, como procuraremos demonstrar, estrutura o discurso e as recomenda  es de pol¨ªtica da an¨¢lise custo-benef¨ªcio. Por nexo comensurabilidade-mercadoriza  o entendemos a associa  o entre a defesa da comensurabilidade, ou seja, da ideia de que ¨¦ sempre poss¨ªvel e desej¨¢vel reduzir as diferentes dimens es de valor dos bens a uma mesma medida, podendo-lhes atribuir um pre o, e a defesa da extens o dos mecanismos de mercado a esferas crescentes da vida social. A teoria da escolha racional ¨¦ o esteio te¨®rico da ACB, esteio cujas fragilidades na an¨¢lise do comportamento dos indiv¨ªduos nem sempre est o claras quando se discutem os m¨¦ritos e dem¨¦ritos deste instrumento. This article sets out to scrutinise the theoretical assumptions and the practical implications of cost-benefit analysis (CBA), currently one of the most influential and controversial instruments used in evaluating public policies offered by economic science. The point of departure is what the authors term the commensurability-commodification nexus which, as they seek to demonstrate, structures the discourse and the policy recommendations of CBA. By commensurability-commodification nexus they mean the association between the defence of commensurability, i.e. the idea that it is always possible and desirable to reduce the different dimensions of the value of goods to an identical measure, to which a price can be attached, and the defence of extending market mechanisms to other spheres of social life. Rational choice theory is the mainstay of CBA, a mainstay whose shortcomings are not always clear when debating the merits and demerits of this instrument in the analysis of individuals¡¯ behaviour. Cet article souhaite recenser les pr¨¦suppos¨¦s th¨¦oriques et les implications pratiques de l¡¯analyse co t-b¨¦n¨¦fice ( ACB), actuellement l¡¯un des plus influents et des plus controvers¨¦s instruments d¡¯¨¦valuation des politiques publiques que propose la science ¨¦conomique. Le point de d¨¦part est ce que nous appelons le lien commensurabilit¨¦-marchandisation qui, comme nous tenterons de le d¨¦montrer, structure le discours et les recommanda-tions de politique de l¡¯analyse co t-b¨¦n¨¦fice. Par lien commensurabilit¨¦-marchandisation, nous entendons l¡¯association entre la d¨¦fense de la commensurabi
