Trade agreements come in all shapes and sizes. Overall, and I, the material provisions of most free trade agreements generally fall into one of two categories: liberalization or governance. The provisions of the liberalisation basket are generally obligations assumed by the parties in order to reduce and limit their protectionism. Explicit tariff reductions, simplification of customs clearance procedures and obligations to open services markets to foreign participants are among the commitments made in trade agreements under the liberalisation category. Both the creation of trade and the diversion of trade have a decisive impact on the establishment of a free trade agreement. The creation of trade will result in a shift in consumption from a cost producer to a low-cost producer, which will lead to an expansion of trade. On the other hand, trade diversion will mean that trade will move from a low-cost producer outside the zone to a more expensive producer in the free trade agreement.  Such offshoring will not benefit consumers under the free trade agreement, which will be deprived of the opportunity to purchase cheaper imported goods. However, economists note that trade diversion does not always harm the overall national well-being: it can even improve national well-being as a whole if the volume of misappropriated trade is low.  The economist has attempted to assess the extent to which free trade agreements can be considered public goods. First, they deal with a key element of free trade agreements, the system of on-board tribunals, which act as arbiters in international trade disputes. These serve as a clarification of existing statutes and international economic policies, as confirmed by trade agreements.
 The stories behind the convincing economic recovery of the 20th century in countries such as Hong Kong and Singapore, Australia and New Zealand, Chile and Mexico, as well as China and India, have in common the commitments of these governments to deep and comprehensive unilateral reforms. Despite these and other examples, trade liberalization has followed a model throughout history – and particularly over the past 85 years – that is best described as a „more mercantile recipiation.“ Although economists tend to appreciate that trade allows us to specialize and that we can produce and consume more through specialization, trade policy is less marked by economics than by issues of political economy.
