Economic Integration - Economic Theory

Economic Theory

The framework of the theory of economic integration was laid out by Jacob Viner (1950) who defined the trade creation and trade diversion effects, the terms introduced for the change of interregional flow of goods caused by changes in customs tariffs due to the creation of an economic union. He considered trade flows between two states prior and after their unification, and compared them with the rest of the world. His findings became and still are the foundation of the theory of economic integration. The next attempts to enlarge the static analysis towards three states+world (Lipsey, et al.) were not as successful.

The basics of the theory were summarized by the Hungarian economist Béla Balassa in the 1960s. As economic integration increases, the barriers of trade between markets diminish. Balassa believed that supranational common markets, with their free movement of economic factors across national borders, naturally generate demand for further integration, not only economically (via monetary unions) but also politically—and, thus, that economic communities naturally evolve into political unions over time.

The dynamic part of international economic integration theory, such as the dynamics of trade creation and trade diversion effects, the Pareto efficiency of factors (labor, capital) and value added, mathematically was introduced by Ravshanbek Dalimov. This provided an interdisciplinary approach to the previously static theory of international economic integration, showing what effects take place due to economic integration, as well as enabling the results of the non-linear sciences to be applied to the dynamics of international economic integration.

Equations describing:

1. enforced oscillations of a pendulum with friction;
2. predator-prey oscillations;
3. heat and/or gas spatial dynamics (the heat equation and Navier-Stokes equations)

were successfully applied towards:

1. the dynamics of GDP;
2. price-output dynamics and the dynamic matrix of the outputs of an economy;
3. regional and inter-regional migration of labor income and value added, and to trade creation and trade diversion effects (inter-regional output flows).

The straightforward conclusion from the findings is that one may use the accumulated knowledge of the exact and natural sciences (physics, biodynamics, and chemical kinetics) and apply them towards the analysis and forecasting of economic dynamics.

Dynamic analysis has started with a new definition of gross domestic product (GDP), as a difference between aggregate revenues of sectors and investment (a modification of the value added definition of the GDP). It was possible to analytically prove that all the states gain from economic unification, with larger states receiving less growth of GDP and productivity, and vice versa concerning the benefit to lesser states. Although this fact has been empirically known for decades, now it was also shown as being mathematically correct.

A qualitative finding of the dynamic method is the similarity of a coherence policy of economic integration and a mixture of previously separate liquids in a retort: they finally get one colour and become one liquid. Economic space (tax, insurance and financial policies, customs tariffs, etc.) all finally become the same along with the stages of economic integration.

Another important finding is a direct link between the dynamics of macro- and micro-economic parameters such as the evolution of industrial clusters and the GDP's temporal and spatial dynamics. Specifically, the dynamic approach analytically described the main features of the theory of competition summarized by Michael Porter, stating that industrial clusters evolve from initial entities gradually expanding within their geographic proximity. It was analytically found that the geographic expansion of industrial clusters goes along with raising their productivity and technological innovation.

Domestic savings rates of the member states were observed to strive to one magnitude, and the dynamic method of forecasting this phenomenon has also been developed. Overall dynamic picture of economic integration has been found to look quite similar to unification of previously separate basins after opening intraboundary sluices, where instead of water the value added (revenues) of entities of member states interact.
