2 Introduction The Chinese government had issued relatively few patents until the mid-2000s. Since then, Chinese firms have obtained thousand of patents. Some economists suggest that those patents will help China sustain the solid economic performance it has experienced in recent years. In this chapter, you will learn about how the use of patents could contribute to a nation’s economic performance.

3 Learning Objectives Define economic growth Recognize the importance of economic growth rates Explain why productivity increases are crucial for maintaining economic growth

4 Learning Objectives (cont'd) Describe the fundamental determinants of economic growth Understand the basis of new growth theory Discuss the fundamental factors that contribute to a nation’s economic development

5 Chapter Outline How Do We Define Economic Growth? Productivity Increases: The Heart of Economic Growth Saving: A Fundamental Determinant of Economic Growth New Growth Theory and the Determinants of Growth Immigration, Property Rights, and Growth Economic Development

6 Did You Know That... An infrared camera that was originally mounted on military helicopters now has household applications? The camera has been incorporated into automobiles to enable drivers to “see” farther into the dark than was possible with standard headlights. This is just one example of innovation that many economists agree as a determinant of economic growth—the topic of this chapter.

7 How Do We Define Economic Growth? Economic growth – can be shown graphically by shifting the production possibilities curve outward – reflects the fact that more of all goods can be produced within the economy

8 Figure 9-1 Economic Growth Distance of shift represents an increase in productive capacity Distance of shift represents an increase in productive capacity

9 How Do We Define Economic Growth? (cont'd) Observation – India has a real GDP more than fifteen times as large as that of Denmark – India’s population is about 200 times greater than that of Denmark – India is relatively poor and Denmark is relatively rich

10 How Do We Define Economic Growth? (cont'd) Economic Growth – Increase in per capita real GDP measured by its rate of change per year

12 International Example: Growth Rates Around the World Table 9-1 shows the average annual rate of growth of real GDP per person in selected countries since Even though the U.S. is one of the world’s richest countries, our rate of economic growth in recent decades has been in the mid-range. U.S. per capita real GDP has remained higher than other nations because we have been able to sustain growth over many decades.

13 Table 9-1 Per Capita Real GDP Growth Rates in Various Countries

14 How Do We Define Economic Growth? (cont'd) Is economic growth bad? – Some psychologists contend that growth makes us worse off – As with all activities, there are costs along with benefits to growth

15 Table 9-2 Costs and Benefits of Economic Growth

16 How Do We Define Economic Growth? (cont'd) The importance of growth rates – Do we need to worry about small differences in the economic growth rate? – A small difference in the rate of economic growth does not matter very much for next year or the year after, but it makes considerable difference for the more distant future due to the power of compounding

17 Table 9-3 One Dollar Compounded Annually at Different Interest Rates

18 3%4%5% $4.38 trillion $7.11 trillion $11.5 trillion How Do We Define Economic Growth? (cont'd) GDP in 50 years at various growth rates starting at $1 trillion

19 How Do We Define Economic Growth? (cont'd) The Rule of 70 – A rule stating that the appropriate number of years required for per capital real GDP to double is equal to 70 divided by the average rate of economic growth – Example: At an annual growth rate of 10%, per capita real GDP should double in about:

20 International Example: Tracking a Global Economic Growth Divergence Between 2007 and 2009, the rate of growth in world per capita real GDP dropped from about 6 percent to -0.5 percent. There was, however, a distinct difference in the growth rates between advanced nations, such as the United States, and developing nations, such as India. While the economic growth rate for developing nations remained positive over that period, the rate of economic growth across all advanced nations was below -3 percent by 2009.

21 Economic growth = Rate of growth of capital + Rate of growth of labor + Rate of growth in the productivity of capital and of labor Productivity Increases: The Heart of Economic Growth

22 Productivity Increases: The Heart of Economic Growth (cont'd) Labor Productivity – Total real domestic output (real GDP) divided by the number of workers (output per worker) or the number of labor hours – It increases whenever average output produced per worker (or per hour worked) during a specific time period increases

23 Figure 9-3 Factors Accounting for Economic Growth in Selected Regions

24 Saving: A Fundamental Determinant of Economic Growth Saving as a determinant of growth – To have more consumption in the future, you have to consume less today and save the difference between your consumption and your income

25 International Example: The High Chinese Saving Rate and Its Growth Implications Since the early 1970s, residents of China have increased their overall rate of saving from 35 percent to 47 percent of real GDP. The bulk of this saving has been channeled into capital investment, which today accounts for more than 45 percent of China’s total expenditures on final goods and services. These high rates of saving and investment in China help to explain the nation’s annual rate of growth of per capita real GDP in excess of 6 percent.

26 Figure 9-4 Relationship Between Rate of Saving and Per Capita Real GDP

27 New Growth Theory and the Determinants of Growth New Growth Theory – A theory of economic growth that examines the factors that determine why technology, research, innovation, and the like are undertaken and how they interact

28 New Growth Theory and the Determinants of Growth (cont'd) Technology: a separate factor of production – When the rewards are greater, the more technological advances will occur

29 New Growth Theory and the Determinants of Growth (cont'd) Research and development (R&D) – Patents A government protection that gives an inventor the exclusive right to make, use, or sell an invention for a limited period of time (currently, 20 years)

30 Figure 9-5 U.S. Patent Grants

31 Why Not … promote innovation by awarding more patents? It is already very easy to obtain a patent from the U.S. Patent and Trademark Office. The Office sometimes even accidentally awards patents to different applicants. Making patents easier to obtain would therefore not likely promote innovation but instead it would encourage more patent applicants to establish a property right through litigation instead of research and development.

32 New Growth Theory and the Determinants of Growth (cont'd) Research and development (R&D) – Positive externalities and R&D For every 1% rise in the stock of R&D in the United States alone, productivity worldwide increases by about 0.25%

33 New Growth Theory and the Determinants of Growth (cont'd) The open economy and economic growth – Free trade encourages the spread of technology

34 Figure 9-6 The Relationship Between Economic Growth and Tariff Barriers to International Trade

35 International Example: What Economic Growth Success Stories Have in Common A study has found that since 1950, 13 nations had experienced 25-year periods of annual growth rates of at least 7 percent. One of the 5 characteristics common to these nations is their openness to international trade. Furthermore, the periods of high economic growth ended for several of these nations when their governments began restricting flows of international trade.

36 New Growth Theory and the Determinants of Growth (cont'd) Innovation – Transforming an invention into something that is useful to humans – New growth theorists believe that real wealth creation comes from innovation – and invention is a facet of innovation

37 New Growth Theory and the Determinants of Growth (cont'd) The importance of ideas and knowledge – Knowledge, ideas, and productivity are related; ideas are what drive economic growth – Economist Paul Romer and other new growth theorists conclude that: economic growth can continue as long as we keep coming up with new ideas

38 New Growth Theory and the Determinants of Growth (cont'd) The importance of human capital – Knowledge, ideas and, productivity are all tied together – Human capital consists of knowledge people acquire – Investing in human capital raises living standards

39 Immigration, Property Rights, and Growth Population and immigration as they affect economic growth – MIT economist Michael Kremer believes population growth drives technological progress Question – Does immigration spur economic growth?

40 Immigration, Property Rights, and Growth (cont'd) Question – How can well-defined property rights stimulate economic growth? Answers – The more certain property rights are, the more capital accumulation there will be – The more certain are property rights, the more entrepreneurship there will be

41 Economic Development Question – How did developed countries travel paths of growth from extreme poverty to relative riches?

42 Economic Development (cont'd) Development Economics – The study of factors that contribute to the economic growth of a country – The goal of economists studying development is to help the 4 billion people with low living standards to join the 2 billion people with moderately high ones

43 Economic Development (cont'd) Putting world poverty into perspective – At least one-half of the world’s population lives at subsistence level – 20% of the world lives on less than $1.50 per day – The U.S. poverty level exceeds the average income of one-half the world

44 Economic Development (cont'd) Relationship between population growth and economic development – There are nearly 6.5 billion people on earth – By 2050, according to the U.N., world population will be close to 9.1 billion – Growth will occur mainly in developing nations

45 Figure 9-7 Expected Growth in World Population by 2050, Panel (a)

46 Figure 9-7 Expected Growth in World Population by 2050, Panel (b)

47 Economic Development (cont'd) Relationship between population growth and economic development – In An Essay on the Principle of Population (1978), Thomas Robert Malthus predicted that world population growth would eventually outstrip food supplies – He was proved wrong as the supply of food has been expanding faster than the increase in demand caused by increased population

48 Economic Development (cont'd) Relationship between population growth and economic development – Growth leads to smaller families – The more economic development occurs, the slower the population growth rate – Birth rates decline with modernization Reduced infant mortality People do not rely on children to take care of them in old age

49 Economic Development (cont'd) The stages of development – Agricultural stage – Manufacturing stage – Services stage

50 Economic Development (cont'd) Keys to economic development – Establishing a system of property rights – Developing an educated population – Letting “creative destruction” run its course – Limiting protectionism

51 You Are There: A Nonabsorbable Fat Finally Finds a Market Niche In 1968, two chemists at Procter & Gamble invented a new type of fat, olestra, which cannot be absorbed by human bodies. The company launched this calorie-free fat in 1996, but then took it off the shelves after discovering its undesirable digestive side effects. Today olestra is used as the base for a new type of paint called Sefose, which can be painted onto almost anything.

52 Issues & Applications: China Discovers the Growth Benefits of Patents Since the mid-2000s, China’s government has worked hard to enforce foreign patents and to spur innovative activity by encouraging Chinese companies to apply for patents. Applications for patents by Chinese firms have increased significantly since Since the late 2000s, Chinese companies have also obtained over 1,000 patents per year in the United States.

53 Figure 9-8 Applications for and Awards of Patents in China Since 1996

54 Summary Discussion of Learning Objectives Economic growth – The rate of economic growth is the annual rate of change in per capita GDP Why economic growth rates are important – Over long intervals, relatively small differences in the economic growth rate can produce large disparities in per capita incomes

55 Summary Discussion of Learning Objectives (cont'd) Why productivity increases are crucial for maintaining economic growth – For a nation with a stable population and steady capital growth, productivity growth is the main factor in economic expansion

56 Summary Discussion of Learning Objectives (cont'd) The key determinants of economic growth – Increases in the labor force, the growth of capital, and the growth of productivity – Higher saving rates contribute to greater investment and increased capital accumulation and growth New growth theory – Emphasizes how rewards to innovation contribute to higher growth rates – Ideas and knowledge are crucial elements

57 Summary Discussion of Learning Objectives (cont'd) Fundamental factors that contribute to a nation’s economic development – Nations that encourage education, have a strong system of property rights, allow creative destruction, and avoid protectionism have higher levels of economic development
