 In addition to his philosophical and theological ambitions, Olivi took part in a theoretical discussion concerning economic justice. He composed a short treatise Tractatus de contractibus (ed. Piron 2012) while he was working at the Franciscan studium generale of Narbonne in mid-1290s. The work is a theoretical treatise that is related to the moral dimension of economic activities and it was probably occasioned by pastoral duties that Franciscan friars had in an urban context. Although Olivi’s views can be traced back to earlier discussions on Roman and Canon law, as well as other works dealing with just price, scholars have also argued that his overall approach profoundly changed medieval economic theory (Kaye 1998, 2014; Langholm 1992, 1998; Piron 2012; Todeschini 2009; a more critical evaluation is Kirshner and Lo Prete 1984).
