3、erent government policies on long-term economic growth. Economic growth, after all, is not inevitable; history has seen long periods of stagnation where no sustained increases in output per capita occurred.Why have some countries been able to achieve rapidly increasing real GDP per capita, while oth
4、er countries have failed to keep pace? Our goal in this chapter is to develop a model of economic growth to help answer questions such as this.LEARNING OBJECTIVE4 2015 Pearson Education, Inc.Economic Growth over Time and around the World11.1Define economic growth, calculate economic growth rates, an
5、d describe global trends in economic growth.5 2015 Pearson Education, Inc.From Prehistory to the Middle AgesEconomist Brad DeLong estimates that in 1,000,000 B.C., our ancestors had a GDP per capita of approximately $145.He estimates that GDP per capita in 1300 A.D. was also about $145. In other wor
6、ds, no sustained economic growth occurred before the middle ages; a peasant on a farm in 1300 A.D. was about as well off his ancestors.6 2015 Pearson Education, Inc.The Industrial RevolutionSignificant economic growth did not really begin until the Industrial Revolution, the application of mechanica
7、l power to the production of goods and services which began in England around 1750. Before this, production of most goods had relied on human or animal power.The use of mechanical power allowed England and other countrieslike the United States, France, and Germanyto begin to experience long-run econ

After that date, the British Parliament, rather than
9、the king, controlled the government. The court system also became independent of the king.The government was then able to make credible promises regarding upholding property rights, protecting wealth, and the elimination of arbitrary tax increases. This, claims North, made entrepreneurs willing to m

11、 world, resulted in sustained increases in real GDP per capita. Average annual growth rates for the world economyFigure 11.19 2015 Pearson Education, Inc.Why Do Growth Rates Matter?The differencebetween 1.3% and2.3% may not seemlike much; but over along period, it makes aremarkable difference.Over 5
12、0 years, a 1.3%growth rate leads toabout a 91% increasein real GDP per capita.But a 2.3% growth rate leads to about a 212% increase.In the long run, small differences in economic growth rates result in big differences in living standards.Average annual growth rates for the world economyFigure 11.110

14、.The 1980s and 1990s have seen some countries progress out of the developing category, like Singapore, South Korea, and Taiwan; these are often referred to as newly industrializing countries.Real GDP per capita is markedly different across the world, even after correcting for cost of living differences. In 2012 it ranged from a high of $103,900 in Qatar to a low of $400 in the Democratic Republic of the Congo.
