We address three themes on the New Regionalism. First, the prominent analogy to a “spaghetti bowl” of economic integration agreements (EIAs) should be replaced by reference to a « market » for EIAs. We suggest a systematic economic framework for analyzing « competitive liberalization » of governments in a static, long-run context. Second, we address why ex post measurements of the average (treatment) effects of EIAs on trade seem so « small ». Third, after addressing evidence for long-run determinants of competitive liberalization, we discuss how one might conceptualize the process by which governments select into EIAs over time, that is, the growth of regionalism. |
