  Introduction to Economic Theory   It’s not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change. Charles Darwin                                               Introduction and Summary Economic theory, generalizations about economies, and economic history began as attempts to understand the Industrial Revolution. The economic theory posts on this blog describe and analyze economic development and economic growth since the start of the Industrial Revolution in the late 1700s.  Some writers describe the current economic trends as the Fourth Industrial Revolution.

The Internet of Things, online shopping and ordering, business conferencing, telemedicine. Or how a particular company was transforming an industry (Amazon, Uber). But now we see that the entire economy –  al l industries and markets – rely on digital. The technology and rapid adaptation are accelerating the shifts. Income inequality is bad and probably getting worse.  The usual reasons given are outsourcing in th...
