How Economies Grow And Develop Answer Key

HOW ECONOMIES GROW AND DEVELOP Chapter Overview This chapter presents material on economic growth, such as the theory behind it, how it is calculated, its history in the world, and its relationship to economic development. You will be able to compare statistical information on different country experiences in trying to determine whether the world’s poor countries are, over time, “catching up” to the rich countries. You will also see what are the main institutional factors that economists consider important in achieving economic growth. Finally, you will see that the chapter contains individual sections on poverty, inequality, and human development; each will allow you to independently examine the subject matter, but also consider its relationship to economic growth. Chapter Objectives After reading and reviewing this chapter, you should be able to: 1. Explain the difference between “economic growth” and “economic development.” 2. Understand the relevance to economics—and to economic growth in particular—of the Industrial Revolution. 3. Describe general patterns of economic growth over time and across different regions and countries. 4. Discuss the controversy concerning whether global inequality is increasing or decreasing. 5. List various factors that play a role in development. 6. Explain how poverty, economic growth, and human development are related.

Economic growth will always lead to inflation. 12. A major cause of Japan’s extraordinary growth in the period of 1950-1980 was its high savings rate, which reached as high as 20 percent of household income in the mid 1970s. 13.

Whether worldwide inequality is increasing or decreasing much debated in the press and popular writings.

Industrial Revolution 6. virtuous cycles (in development) 7. convergence 8. bilateral 9. multilateral 10. foreign direct (investment) 11. False, the effect of economic growth on inflation is ambiguous. If the AS curve shifts further to the right than the AD curve, the inflation rate may decline. If the AD curve shifts further to the right than the AS curve, the inflation rate may rise. 12. True. 13. False. Poorly planned or misguided development projects may lead to waste or even harm. 14. False. While natural resources are generally very important, there are some economies with few natural resources that have done very well (e.g. Hong Kong and Singapore, which are natural ports but have little energy or mineral resources or arable land). 15. False. Some countries, like China and Vietnam, have been successful in achieving economic growth without a system of private property rights. 16. False. Economic growth often helps, but it is not required. Human development has many dimensions, and it could be achieved through progress in many different areas unrelated to income. 17. Economic growth is the growth in production of output (or income), and can be measured as the percent change in real GDP. Economic development is the movement of the population from poverty into a situation of material plenty or wellbeing. 18. Growth in real GDP per capita = growth in real GDP – growth in population. 19. It is an equation that measures the growth rate of output per worker. Specifically, it is: growth rate of output per worker = growth rate of total factor productivity + 0.3(growth rate of manufactured capital per worker). 20. The idea of convergence is that the poor countries are on a path to “catch up” with the rich countries, because they are starting off with little capital. So as they experience increases in their manufactured capital stock, their output will grow at a faster rate than that of rich countries that are already rich in manufactured capital. 21. If one examines the number of poor countries remaining in poverty, and one counts each country equally, then it appears convergence is not occurring. But if one adjusts for population and look at the number of people moving out of poverty, it does appear convergence is occurring. This is primarily due to the rapid growth rates of the two most populous countries, China and India. 22. The factors that can promote economic growth include: savings and investment, technological innovation and entrepreneurship, good macroeconomic policies that 12 stabilize aggregate demand, access to international markets, availability of natural resources, access to foreign capital, good institutions. These factors are not requirements for economic growth, however, as there are many examples of countries that have achieved growth without one or more of these factors. 23. The beneficial institutions include: a good banking system; a good legal system with private property rights and contact enforcement; and the absence of corruption, internal conflict, and political instability. 24. Because developing countries are currently paying back more due to their heavy debt burdens, than what they receive in new loans. 25. Despite rapid economic growth in both countries in recent decades, China has made significantly more progress in improving the capabilities of its people. It has placed a greater priority in developing the economic potential of its population. Unless human freedom is utmost priority in one’s conception of development—China’s government is authoritarian, India’s is a democracy—China has made more progress is human development. Answers to Problems 1. a. [(301.3 286.9) / 286.9] × 100 = 5.0% b. Real GDP per capita for 2012 = $286,900,000,000 / 220,500,000 = $1,301 Real GDP per capita for 2013 = $301,300,000,000 / 223,000,000 = $1,351 c. [(223.0 220.5)/220.5] × 100 = 1.1% d. 5.0% 1.1% = 3.9% Calculating the percentage change in real GDP per capita from part b, as (13511301)/1301 × 100, gives a rate of 3.8%. This is also an acceptable answer. Technical Note: The simple formula given for figuring percentage changes is to blame for the discrepancy between the two answers. In practice, professional economists often use a different formula--the “log-difference formula”--to calculate percentage changes. Using the “ln” (natural log) function on a calculator or spreadsheet, the equation [ln(GDP2013) - ln(GDP2012)] × 100 gives a measure of percentage change. Using this method of calculating percentage changes, there would be no discrepancies (except due to rounding.) 13 2. a. Economic growth with inflation rising. b. Economic growth with inflation falling. 3. a. 2% + .3(3%) = 2.6% b. Plugging in the numbers, 1.5% = growth rate of A + .3(3%). This implies that 1.5% .9% = 0.6% is the growth rate of A. 14 4.a. Chart not provided b. Yes, looking only at this evidence, it would appear that convergence may be occurring. The poorer countries tend, on balance, to have faster growth rates than the richer countries, and are on the path to “catch up” to them. c. Chart not provided d. Now it does not appear that convergence is occurring, because the poor countries are growing at rates generally less than those of the developed countries. e. Neither “study” looks at the whole picture. Answers to Self Test Questions 1. C 2. E 3. C 4. C 5. C 6. B 7. E 8. E 9. E 10. D 11. E 12. C 13. A 14. B 15. B 16. A 17. E 18. A 19. A 20. D 21. E 22. A 15
