While regionalism may threaten multilateralism, we simply do not know at this time. Given that regionalism has become and will remain the preferred form of mutual liberalization for most countries – whatever we say economists – we should therefore focus on ways to integrate regionalism more effectively into multilateralism. Countries following the neo-Marxist model have generally encouraged education and high national savings to finance their expanding export industries. For example, in Japan, the savings rate has often exceeded 20% of GDP and is now approaching 40% of China`s GDP. (In contrast, over the past decade, the U.S. savings rate has been only about 2% and has even been negative in a few years.) From the time of Adam Smith in 1776 until the introduction of the GATT in 1947, the theory of economic trade developed quite slowly. However, since the creation of the GATT in 1947, there have been a number of significant changes in the traditional Western economic theory of international trade. These amendments largely update the fundamental theory of trade to reflect the new realities of industry and trade. Jackson, of the Congressional Research Service, said, “These models include assumptions about consumer behavior, market structure and organization, production technologies, investments and capital flows in the form of foreign direct investment.”  In addition to the diversion of trade and the creation of trades that have essentially static effects, participants in free trade zones and customs union unions are also striving for dynamic benefits, such as the expansion of production. B, because companies are taking advantage of the growing size of the market to increase production and improve efficiency as firms adapt to increased competition.
Access to a larger market is particularly important for small countries whose economies are too small to warrant large-scale production. Two factors that can lead to a current account deficit or surplus are a nation`s level of savings and investment relative to consumption and the exchange rate between its currency and that of its trading partners. Conversely, the level of a country`s savings and investment relative to its consumption is linked to its trade balance. Joseph Stiglitz sums up: “Trade deficits and foreign loans are two sides of the same coin. If borrowing from abroad increases, the trade deficit will also increase. This means that if government lending increases, private savings do not increase accordingly (or private investment decrease accordingly), the country will have to borrow more abroad and the trade deficit will increase. The reserve country can be considered an export of T-Bills in exchange for the importation of goods and services.  The success of some countries adopting a neo-Marxist strategy does not refute the law of comparative advantage.
In fact, the reason these countries succeed is because they focus on areas where they have or can create a comparative advantage. Thus, Japan focused first on industries such as steel and cars, then on electronics, where a policy of import protection and domestic subsidies could allow their domestic companies to compete in global markets and, in particular, in the U.S. market. In this world, the classic Ricardian trading model has provided a good explanation for business models such as product producing countries such as. B which countries would produce these products. England would produce textiles on the basis of its wool production and capital availability, and Portugal would produce wine on the basis of its sun and fertile soil. If Portugal decided to create barriers to imports of British textiles, its economy would be weaker and it would still be in Britain`s interest to allow the free importation of Portuguese wine. Geza Feketukuty, the leading U.S. negotiator for services in the Uruguay Round, gives a wonderful anecdote about the early efforts to begin negotiations on trade in
