  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. Other observers and commentators believe that information and communication technology and applications have become so central to the economy that we are in the Information Revolution. And others believe that we are at the beginning of the Biotechno...

Adam Smith - Our Founding Father ADAM SMITH VISITS A PIN FACTORY   Adam Smith’s description of a pin factory is on the first page of  The Wealth of Nations .  (Chapter 1 – “Of the Division of Labour”)  Drawings of pin factories of this period show workers using hand tools. Smith says the process can be broken down into 18 distinct steps, including packaging the pins. Smith mentions that pin factory workers were poorly paid, despite their high productivity.    Adam Smith says he visited a pin factory employing 10 men who produced 48,000 pins per day.  If each of the ten workers had done all the steps themselves, Smith says each worker could produce only 10 or 20 pins per day.  So the pin factory replaces 2,400 to 4,800 pin makers. The increase in labor productivity (output per person per day) is as high as 50 times that of individual pin makers.     This reduction in unit cost or average cost (AC) and the huge i...

  INTRODUCTION The main topic of economics should be economic growth and development, “the nature and causes of the wealth of nations.” (Adam Smith) The main questions are: How do capitalist economies grow? What is the relationship between economic growth and economic development? What is innovation and its relationship to economic development? ECONOMIC GROWTH Economic growth is the growth rate of total output, usually measured by real Gross Domestic Product (GDP). Total output is not measured directly. Sales (nominal GDP) are added up and the growth rate calculated. The inflation rate is calculated separately and subtracted from the growth rate of nominal GDP. What remains is the growth rate of real GDP. Between 1950 and 2000, the U.S. economy (real GDP) grew at about 3.5% per year. Since 2000, with two recessions, the growth rate has been around 2.0% per year. Even the recovery from the 2008-2009 recession has been only somewhat above 2.0%.  Small changes in compound growth ...

INTRODUCTION This post and the next is on the topic of economic development and its contribution to economic growth.   Since the beginning of the Industrial Revolution more than 200 years ago, this is the central economic dynamic.    The following are factors that led to American economic development, many in place  before the beginning of the Industrial Revolution.   The United States, more than any other country, was positioned to take advantage of the new technology and ideas that were the basis of the Industrial Revolution.   The following is an outline of those factors.   For the full story of the early decades of America's Industrial Revolution, see Engines of Change and some of the excellent histories written about America after the Revolution. FACTORS IN AMERICAN ECONOMIC DEVELOPMENT AND GROWTH The usual narrative centers on the inventors and entrepreneurs who developed and commercialized new production and tran...
