The Agricultural Revolution

The first true economies arrived when people started raising crops and domesticating animals. Although there is still a great deal of disagreement among archeologists as to the exact timeline, research indicates that agriculture began independently and at different times in several places around the world. The earliest agriculture was in the Fertile Crescent in the Middle East around 11,000–10,000 years ago. Next were the valleys of the Indus, Yangtze, and Yellow rivers in India and China, between 10,000 and 9,000 years ago. The people living in the highlands of New Guinea developed agriculture between 9,000 and 6,000 years ago, while people were farming in Sub-Saharan Africa between 5,000 and 4,000 years ago. Agriculture developed later in the western hemisphere, arising in what would become the eastern United States, central Mexico, and northern South America between 5,000 and 3,000 years ago (Diamond 2003).

Agriculture began with the simplest of technologies—for example, a pointed stick to break up the soil—but really took off when people harnessed animals to pull an even more efficient tool for the same task: a plow. With this new technology, one family could grow enough crops not only to feed themselves but also to feed others. Knowing there would be abundant food each year as long as crops were tended led people to abandon the nomadic life of hunter-gatherers and settle down to farm.

The improved efficiency in food production meant that not everyone had to toil all day in the fields. As agriculture grew, new jobs emerged, along with new technologies. Excess crops needed to be stored, processed, protected, and transported. Farming equipment and irrigation systems needed to be built and maintained. Wild animals needed to be domesticated and herds shepherded. Economies begin to develop because people now had goods and services to trade. At the same time, farmers eventually came to labor for the ruling class.

As more people specialized in nonfarming jobs, villages grew into towns and then into cities. Urban areas created the need for administrators and public servants. Disputes over ownership, payments, debts, compensation for damages, and the like led to the need for laws and courts—and the judges, clerks, lawyers, and police who administered and enforced those laws.

At first, most goods and services were traded as gifts or through bartering between small social groups (Mauss 1922). Exchanging one form of goods or services for another was known as bartering. This system only works when one person happens to have something the other person needs at the same time. To solve this problem, people developed the idea of a means of exchange that could be used at any time: that is, money. Money refers to an object that a society agrees to assign a value to so it can be exchanged for payment. In early economies, money was often objects like cowry shells, rice, barley, or even rum. Precious metals quickly became the preferred means of exchange in many cultures because of their durability and portability. The first coins were minted in Lydia in what is now Turkey around 650–600 B.C.E. (Goldsborough 2010). Early legal codes established the value of money and the rates of exchange for various commodities. They also established the rules for inheritance, fines as penalties for crimes, and how property was to be divided and taxed (Horne 1915). A symbolic interactionist would note that bartering and money are systems of symbolic exchange. Monetary objects took on a symbolic meaning, one that carries into our modern-day use of cash, checks, and debit cards.

As city-states grew into countries and countries grew into empires, their economies grew as well. When large empires broke up, their economies broke up too. The governments of newly formed nations sought to protect and increase their markets. They financed voyages of discovery to find new markets and resources all over the world, which ushered in a rapid progression of economic development.

Colonies were established to secure these markets, and wars were financed to take over territory. These ventures were funded in part by raising capital from investors who were paid back from the goods obtained. Governments and private citizens also set up large trading companies that financed their enterprises around the world by selling stocks and bonds.

Governments tried to protect their share of the markets by developing a system called mercantilism. Mercantilism is an economic policy based on accumulating silver and gold by controlling colonial and foreign markets through taxes and other charges. The resulting restrictive practices and exacting demands included monopolies, bans on certain goods, high tariffs, and exclusivity requirements. Mercantilistic governments also promoted manufacturing and, with the ability to fund technological improvements, they helped create the equipment that led to the Industrial Revolution.

The Industrial Revolution

Until the end of the eighteenth century, most manufacturing was done by manual labor. This changed as inventors devised machines to manufacture goods. A small number of innovations led to a large number of changes in the British economy. In the textile industries, the spinning of cotton, worsted yarn, and flax could be done more quickly and less expensively using new machines with names like the Spinning Jenny and the Spinning Mule (Bond 2003). Another important innovation was made in the production of iron: Coke from coal could now be used in all stages of smelting rather than charcoal from wood, which dramatically lowered the cost of iron production while increasing availability (Bond 2003). James Watt ushered in what many scholars recognize as the greatest change, revolutionizing transportation and thereby the entire production of goods with his improved steam engine.

As people moved to cities to fill factory jobs, factory production also changed. Workers did their jobs in assembly lines and were trained to complete only one or two steps in the manufacturing process. These advances meant that more finished goods could be manufactured with more efficiency and speed than ever before.

The Industrial Revolution also changed agricultural practices. Until that time, many people practiced subsistence farming in which they produced only enough to feed themselves and pay their taxes. New technology introduced gasoline-powered farm tools such as tractors, seed drills, threshers, and combine harvesters. Farmers were encouraged to plant large fields of a single crop to maximize profits. With improved transportation and the invention of refrigeration, produce could be shipped safely all over the world.

The Industrial Revolution modernized the world. With growing resources came growing societies and economies. Between 1800 and 2000, the world’s population grew sixfold, while per capita income saw a tenfold jump (Maddison 2003).

While many people’s lives were improving, the Industrial Revolution also birthed many societal problems. There were inequalities in the system. Owners amassed vast fortunes while laborers, including young children, toiled for long hours in unsafe conditions. Workers’ rights, wage protection, and safe work environments are issues that arose during this period and remain concerns today.

Postindustrial Societies and the Information Age

Postindustrial societies, also known as information societies, have evolved in modernized nations. One of the most valuable goods of the modern era is information. Those who have the means to produce, store, and disseminate information are leaders in this type of society.

One way scholars understand the development of different types of societies (like agricultural, industrial, and postindustrial) is by examining their economies in terms of four sectors: primary, secondary, tertiary, and quaternary. Each has a different focus. The primary sector extracts and produces raw materials (like metals and crops). The secondary sector turns those raw materials into finished goods. The tertiary sector provides services: child care, healthcare, and money management. Finally, the quaternary sector produces ideas; these include the research that leads to new technologies, the management of information, and a society’s highest levels of education and the arts (Kenessey 1987).

In underdeveloped countries, the majority of the people work in the primary sector. As economies develop, more and more people are employed in the secondary sector. In well-developed economies, such as those in the United States, Japan, and Western Europe, the majority of the workforce is employed in service industries. In the United States, for example, almost 80 percent of the workforce is employed in the tertiary sector (U.S. Bureau of Labor Statistics 2011).

The rapid increase in computer use in all aspects of daily life is a main reason for the transition to an information economy. Fewer people are needed to work in factories because computerized robots now handle many of the tasks. Other manufacturing jobs have been outsourced to less-developed countries as a result of the developing global economy. The growth of the Internet has created industries that exist almost entirely online. Within industries, technology continues to change how goods are produced. For instance, the music and film industries used to produce physical products like CDs and DVDs for distribution. Now those goods are increasingly produced digitally and streamed or downloaded at a much lower physical manufacturing cost. Information and the means to use it creatively have become commodities in a postindustrial economy.
