Economic interdependence

Economic interdependence is a consequence of specialization, or the division of labor, and is almost universal. It was described as early as 1828, when A. A. Cournot wrote:

:"but in reality the economic system is a whole of which the parts are connected and react on each other. An increase in the incomes of the producers of commodity A will affect the demand for commodities B, C, etc., and the incomes of their producers, and, by its reaction will change the demand for commodity A." [From the beginning of Chapter XI of "The Mathematical Principles of the Theory of Wealth", 1838, as translated from the French by Nathaniel Bacon.]

Interdependence is not rigid because firms, individuals and nations may change from the production of one set of products to that of another. Its effects are evident in most general equilibrium theory models which usually require a computer to sort out the complex interactions.

The economic interdependence of nations and groups of nations is of special importance. It describes countries/nation-states and/or supranational states such as the European Union (EU) or North American Free Trade Agreement (NAFTA) that are specialized because of climate, the availability of labor and capital, and a variety of historical and cultural factors. Such nations or groups may be dependent on one another for any (or all) of the following:

*food
*energy
*minerals
*manufactured goods
*multinational/transnational corporations
*financial institutions
*foreign debt
