Gilbert's essay collection Joint Commitment (2014) contains eighteen recent papers that together address most of the topics in the above list along with several others that Gilbert argues can be illuminated by an appeal to joint commitment. Gilbert's book Rights and Demands (2018) is the first extended treatment of demand-rights, a class of rights that, she argues, are apt to be considered rights par excellence. To have a demand-right is to have the standing to demand an action of someone. That person is, correspondingly, obligated to the right-holder to perform the act in question. Seeking to answer the question "How are demand rights possible?" Gilbert argues for two main theses. First, joint commitment is a ground of demand-rights. Second, joint commitment may well be their only ground. In this connection Gilbert asks whether there are demand-rights whose existence can be demonstrated by moral argument without invoking a joint commitment, and finds wanting existing arguments to the effect that there are. She also argues against the possibility of accruing demand-rights through the existence of a given legal system or other institution without the involvement of a joint commitment. The final chapter of the book applies its findings to the topic of human rights. In the course of Rights and Demands Gilbert engages with the work of central figures in contemporary rights theory such as H. L. A. Hart, Joseph Raz and Judith Thomson, and with prominent human rights theorists such as Charles Beitz and Alan Buchanan. She argues that promises and agreements - both commonly understood to ground demand-rights - are constituted by joint commitments, rejecting promise theorists' standard assumption that the obligations most closely associated with promises are a matter of moral requirement. Gilbert's work has influenced a number of theorists outside philosophy including that of developmental psychologist Michael Tomasello.
