Money moves over, around and through them [national borders] with the speed of light. The flows of capital are now in the range of 30 to 50 times greater than world trade. The world's capital market that moves along this electronic highway goes where it is wanted and it stays where it is well-treated … As long as our free-market system permits and delivers an acceptable rate of return on investment in an environment of political stability that is competitive with other areas of investment, the capital will keep coming.
In this chapter we extend our applications of the economic way of thinking to international trade and finance and environmental economics, relying again extensively on supply and demand graphs. We cover international economics early in the book for a straightforward reason: international trade and finance have become progressively more important issues for business. Moveover, national economies have become integrated and interdependent to a degree not imagined just a few decades back. The business of much business has become global in scope because of technological gains in transportation and telecommunications. The extent of the integration of national economies has been dramatized in recent years through the rapid spread of the financial crisis, attributable to the bursting of the housing price bubble and the collapse of the market for mortgage-backed securities, that became evident in the United States's banking system in late 2007, only to cause a growing list of major banks around the world to hover on the brink of bankruptcy in 2008 and 2009.
