摘要: Why do agents comply with the norms embedded in regimes and international institutions? Scholars have proposed two competing answers to this compliance puzzle, one rationalist, other constructivist. Rationalists emphasize coercion, cost/benefit calculations, material incentives; constructivists stress social learning, socialization, norms. Both schools, however, explain important aspects of compliance. To build a bridge between them, I examine role argumentative persuasion learning. This makes explicit theory choice interaction implicit many constructivist studies, it broadens rationalist arguments about instrumental noninstrumental processes through which actors comply. argue that domestic politics—in particular, institutional historical contexts—delimit causal persuasion/social thus helping both rationalists refine scope their claims. assess plausibility these arguments, why states new citizenship/membership promoted by European regional organizations.
