In «Contratos Incompletos y Solución de Controversias» Francisco González de Cossío tackles an age-old legal discussion (the utility of alternative dispute resolution mechanisms) from another angle: economics. The point of departure are recent economic studies that merited the Nobel Prize—specifically the theory of «incomplete contracts». From the same, the author derives normative lessons for legal practitioners. The moral: there are areas of coincidence between law and economics. In realizing this overlap, attorneys can do much to achieve and important legal goal: efficiency in the pursuit of justice.
