[L]ittle research has addressed whether, and in what ways, regimes ‘matter’. Do regimes have Independent influence on state behaviour and, if so, how?
One of the more surprising features of the emerging literature on regimes is the relative absence of sustained discussions of the significance of regimes . . . as determinants of collective outcomes at the international level . . . The ultimate justification for devoting substantial time and energy to the study of regimes must be the proposition that we can account for a good deal of the variance in collective outcomes . . . in terms of the impact of Institutional arrangements. [H]owever, this proposition is relegated to the realm of assumptions rather than brought to the forefront as a focus for analytical and empirical investigations.
