World Trade and Local Public Interest: Trade Liberalization and National Regulatory Sovereignty

Trade liberalization has shaped international economic relations since the conclusion of the GATT 1947. The last few decades have seen a significant shift in the focus of this process: multilateralism seems to have reached its limits, giving way to regionalism, and the focus of trade liberalization has shifted to non-tariff barriers. While these developments have attracted considerable attention, exploring them from comparative perspectives has been largely neglected. Trading systems – the WTO, regional economic integrations and federal systems – are all based on the same dichotomy of free trade and local public interest: they generally prohibit the constituent parties (states) from restricting trade, but exempt them from this limitation if the restriction is warranted by a legitimate local end.
