The size and quality of goods also have an impact on TOTs. Bigger, better quality products are likely to cost more. If the goods sell at a higher price, a seller has additional capital to buy more goods. It is also important to note that a free trade agreement is a reciprocal agreement that is authorized by Article XXIV of the GATT. Autonomous trade agreements for developing and least developed countries are permitted by the 1979 decision by the signatories of the General Agreement on Tariffs and Trade (GATT) (“empowerment clause”) on differentiated and more favourable treatment, reciprocity and increased participation of developing countries. It forms the legal basis for the WTO`s Generalized Preference System (GSP).  Free trade agreements and preferential trade agreements (as mentioned by the WTO) are considered an exception to the MFN principle.  The explosion in public debt could also weigh on trade and GDP growth in the long term. While rich countries are unlikely to face sovereign debt crises as a result of fiscal expansion, the poorest countries may consider their increased debt to be extremely heavy.
Deficit spending could also affect trade balances, reduce national savings and increase trade deficits in some countries. World trade in goods declined by 14.3% in the second quarter compared to the previous period, the largest decline on record, but the impact varied widely from region to region (Chart 3). The largest declines occurred in Europe and North America, where exports decreased by 24.5% and 21.8%, respectively. By comparison, Asian exports remained relatively unaffected, with a decline of only 6.1%. Over the same period, imports decreased by 14.5% in North America and 19.3% in Europe, but only by 7.1% in Asia. Scarcity – the number of products available for trade – is such a factor. The more merchandise a seller has to sell, the more merchandise they will sell, and the more goods the seller will be able to buy with the capital from the sales. Both the creation of trade and the diversion of trade have a decisive impact on the establishment of a free trade agreement.
