Экономическая интеграция государств: теория и практика

Unification of policies between states

Economic integration is the unification of economic policies between different states, through the partial or full abolition of tariff and non tariff restrictions on trade. The trade stimulation effects intended by means of economic integration are part of the contemporary economic Theory of the Second Best: where, in theory, the best option is free trade, with free competition and no trade barriers whatsoever. Free trade is treated as an idealistic option, and although realized within certain developed states, economic integration has been thought of as the "second best" option for global trade where barriers to full free trade exist. Economic integration is meant in turn to lead to lower prices for distributors and consumers with the goal of increasing the level of welfare, while leading to an increase of economic productivity of the states.

There are economic as well as political reasons why nations pursue economic integration. The economic rationale for the increase of trade between member states of economic unions rests on the supposed productivity gains from integration. This is one of the reasons for the development of economic integration on a global scale, a phenomenon now realized in continental economic blocs such as ASEAN, NAFTA, USAN, the European Union, AfCFTA, and the Eurasian Economic Union; and proposed for intercontinental economic blocks, such as the Comprehensive Economic Partnership for East Asia and the Transatlantic Free Trade Area. Comparative advantage refers to the ability of a person or a country to produce a particular good or service at a lower marginal and opportunity cost over another. Comparative advantage was first described by David Ricardo who explained it in his 1817 book On the Principles of Political Economy and Taxation in an example involving England and Portugal. In Portugal, it is possible to produce both wine and cloth with less labour than it would take to produce the same quantities in England. However, the relative costs of producing those two goods are different in the two countries. In England, it is very hard to produce wine and only moderately difficult to produce cloth. Both are easy to produce in Portugal. Therefore, while it is cheaper to produce cloth in Portugal than England, it is cheaper still for Portugal to produce excess wine, and trade that for English cloth. Conversely, England benefits from this trade because its cost for producing cloth has not changed but it can now get wine at a lower price, closer to the cost of cloth. The conclusion drawn is that each country can gain by specializing in the good where it has comparative advantage, and trading that good for the other. Economies of scale refers to the cost advantages that an enterprise obtains due to expansion. There are factors that cause a producer's average cost per unit to fall as the scale of output is increased. Economies of scale is a long run concept and refers to reductions in unit cost as the size of a facility and the usage levels of other inputs increase. Economies of scale is also a justification for economic integration, since some economies of scale may require a larger market than is possible within a particular country — for example, it would not be efficient for Liechtenstein to have its own car maker, if they would only sell to their local market. A lone car maker may be profitable, however, if they export cars to global markets in addition to selling to the local market. Besides these economic reasons, the primary reasons why economic integration has been pursued in practise are largely political. The Zollverein or German Customs Union of 1867 paved the way for partial German unification under Prussian leadership in 1871. "Imperial free trade" was (unsuccessfully) proposed in the late 19th century to strengthen the loosening ties within the British Empire. The European Economic Community was created to integrate France and Germany's economies to the point that they would find it impossible to go to war with each other.

Among the requirements for successful development of economic integration are "permanency" in its evolution (a gradual expansion and over time a higher degree of economic/political unification); "a formula for sharing joint revenues" (customs duties, licensing etc.) between member states (e. g., per capita); "a process for adopting decisions" both economically and politically; and "a will to make concessions" between developed and developing states of the union. A "coherence" policy is a must for the permanent development of economic unions, being also a property of the economic integration process. Historically the success of the European Coal and Steel Community opened a way for the formation of the European Economic Community (EEC) which involved much more than just the two sectors in the ECSC. So a coherence policy was implemented to use a different speed of economic unification (coherence) applied both to economic sectors and economic policies. Implementation of the coherence principle in adjusting economic policies in the member states of economic block causes economic integration effects.

Globalization refers to the increasing global relationships of culture, people, and economic activity. With economics crisis started in 2008 the global economy has started to realize quite a few initiatives on regional level. It is unification between the EU and US, expansion of Eurasian Economic Community (now Eurasia Economic Union) by Armenia and Kyrgyzstan. It is also the creation of BRICS with the bank of its members, and notably high motivation of creating competitive economic structures within Shanghai Organization, also creating the bank with many multi currency instruments applied. Engine for such fast and dramatic changes was insufficiency of global capital, while one has to mention obvious large political discrepancies witnessed in 2014–2015. Global economy has to overcome this by easing the moves of capital and labor, while this is impossible unless the states will find common point of views in resolving cultural and politic differences which pushed it so far as of now.

In economics the word integration was first employed in industrial organisation to refer to combinations of business firms through economic agreements, cartels, concerns, trusts, and mergers—horizontal integration referring to combinations of competitors, vertical integration to combinations of suppliers with customers. In the current sense of combining separate economies into larger economic regions, the use of the word integration can be traced to the 1930s and 1940s. Fritz Machlup credits Eli Heckscher, Herbert Gaedicke and Gert von Eyern as the first users of the term economic integration in its current sense. According to Machlup, such usage first appears in the 1935 English translation of Hecksher's 1931 book Merkantilismen (Mercantilism in English), and independently in Gaedicke's and von Eyern's 1933 two volume study Die produktionswirtschaftliche Integration Europas: Eine Untersuchung über die Aussenhandelsverflechtung der europäischen Länder.
