This paper develops the normative logic of two-level games linking international negotiation and domestic acceptability. The kernel of the logic is to be found in the claim that normatively governed relations involve agents simultaneously asking whether the expectations that they have under an agreement are reasonable given the expectations of others under that agreement. This normative logic mirrors the empirical logic that Putnam (1988) identified in his seminal account.
The normative logic is derived from a consideration of relevant concepts of representation, and in particular the concepts of authorization in international negotiation and accountability in domestic ratification. Rawls’ (1996) distinction between the reasonable and the rational is then deployed to state normative conditions of domestic acceptability as well as the obligations of fairness that states owe to one another. Two implications for democratic theory are drawn.
