Abstract:
The traditional instruments of protectionism (tariffs and quotas) are increasingly unimportant in the international economy, owing to the success of trade liberalizing accords such as the WTO/GATT, NAFTA and the Treaty of Rome. The attention of the trading community has accordingly shifted to various "nontariff barriers" to trade, which remain important in many goods sectors and which lie at the heart of impediments to international trade in services. One source of such impediments, indeed perhaps the most important source, is the variation among nations in their domestic regulatory policies - what I term "regulatory heterogenity." In many ways, regulatory harmonization might seem the most straightforward solution to the trade problems associated with regulatory heterogenity, however, such harmonization rarely occurs, especially at the global level. This paper asks why, and further inquires whether the absence of greater regulatory harmonization is unfortunate.
