Determining Central Ideas How do the world's economies interact and affect one another? (Please, do not answer what Google implies is the answer to my question)

International trade increases the total level of production and consumption in the world, lowers the costs of production and prices that consumers pay, and increases standards of living.

EXAMPLE:

A Very Long-Term View

The many meanings of the word "globalization" have accumulated very rapidly, and recently, and the verb, "globalize" is first attested by the Merriam Webster Dictionary in 1944. In considering the history of globalization, some authors focus on events since 1492, but most scholars and theorists concentrate on the much more recent past.

But long before 1492, people began to link together disparate locations on the globe into extensive systems of communication, migration, and interconnections. This formation of systems of interaction between the global and the local has been a central driving force in world history. [for very, very long-term world system history, see Andre Gunder Frank and especially "the five thousand year world system: an interdisciplinary introduction," by Andre Gunder Frank and Barry K. Gills.]

Q: what is global?A: the expansive interconnectivity of localities -- spanning local sites of everyday social, economic, cultural, and political life -- a phenonmenon but also an spatial attribute -- so a global space or geography is a domain of connectivity spanning distances and linking localities to one another, which can be portrayed on maps by lines indicating routes of movement, migration, translation, communication, exchange, etc.

Q: what is globalization?A: the physical expansion of the geographical domain of the global -- that is, the increase in the scale and volume of global flows -- and the increasing impact of global forces of all kinds on local life. Moments and forces of expansion mark the major turning points and landmarks in the history of globalization
