In this chapter, we will consider the effects of different 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 other 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

The use of mechanical power allowed England and other countries— like the United States, France, and Germany—to begin to experience long-run economic growth

Nobel Laureate Douglass North argues that the Glorious Revolution of 1688 was a key turning point in the economic history of Britain. • After that date, the British Parliament, rather than 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 make the investments necessary for the Industrial Revolution to take hold

© 2015 Pearson Education, Inc. 8 Why Do Growth Rates Matter? The difference between 1.3% and 2.3% may not seem like much; but over a long period, it makes a remarkable difference. Over 50 years, a 1.3% growth rate leads to about a 91% increase in 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 economy Figure 11.1

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
