ECON 10233 Introduction to Macroeconomics John Lovett Chapter 8: Even More Study Questions Name: ___________________ Class (day & time): _____________ Discussing the concepts and working examples with others is allowable. However, receiving answers from someone else, and turning these answers in as your own, is a form of academic dishonesty. Having someone else calculate your answers for you, and turning these answers in as your own, is likewise a form of academic dishonesty. As such, it is subject to the sanctions allowed by your university. Accordingly, the work and answers on this homework are mine and mine alone. I did not receive any assistance on this homework that constitutes academic dishonesty as such. Signed ___________________________ (your signature) 1. - 3. Julian is living in an age in which both population and Real GDP/capita are increasing, on average, by at least 1% per year. This 1% or higher increase in real GDP/capita is typical for the whole of Julian’s life. What time period might Julian be living in?

They have been to some of today’s richest and poorest areas of the world. Julius is deeply upset by the gap between rich nations and poor nations today. Brutus thinks it’s no big deal. Brutus states, “There’s always been rich and poor nations. The typical rich nation today has 20 times the GDP/capita of the typical poor nation, and it’s been that way for at least 1,000 years.” Is Brutus correct? a. No. The gap between rich and poor nations decreased starting about 200 years ago. b. No. The gap between rich and poor nations decreased starting about 500 years ago. c. No. The gap between rich and poor nations increased starting about 200 years ago. d. No. The gap between rich and poor nations increased starting about 500 years ago. e. Yes, the gap between rich and poor nations has stayed relatively constant for the past 1,000 years. 1 ECON 10233 Introduction to Macroeconomics John Lovett 8. _____ What’s so special about a long-run growth rate of GDP/capita at, or above, 1% per year? a. Based on empirical data, birthrates fall and population stabilizes when a 1% growth rate is reached. b. 1%/year is roughly the rate at which changes begin to be obvious within one lifetime. c. A 1%/year growth of GDP/capita compensates for the wearing out of the capital stock. Therefore, a 1% growth rate is needed to maintain living standards. d. Based on empirical data, 1% growth rate of GDP/capita is needed for population to increase. Population cannot increase until GDP/capita grows at least 1%/year. e. It’s a great kisser. 9. _____ What else is special about a long-run growth rate of GDP/capita at, or above, 1% per year? a. 1% is the growth rate the UN Development Committee estimated will eliminate poverty. b. A sustained growth rate of 1% was not seen until the start of the “modern era,” about 200 years ago. A 1% growth rate roughly defines modernity. c. 1% is the growth rate the Augustine Commission recommended as a target for the United States. d. A 1% growth rate is approximately the growth rate at which the natural environment is sustainable. e. It’s really cute and cuddly. 10. -11 ______________________ Roughly when did the UK, the United States, and much of Western Europe, first see sustained growth rates of per capita GDP at/above 1% per year? (counts as two) #’s 12 – 17: Two countries currently have the same Real GDP/capita, $10,000. In the first country Real GDP/capita is growing at 2%/year, whereas in the second it is growing at 3%/ year. 12. - 14. At the top of the next page show the GDP/capita for the two countries over the next 10 years. Assume the growth rate for each country does not change during this period (i.e., they stay at the numbers above (2% and 3%). 15. -17. At the bottom of the next page show the GDP/capita for the two countries over the next 100 years. Assume the growth rate for each country does not change during this period (i.e., they stay at the numbers above (2% and 3%). Notes for #’s 12 – 17: • You need to put in axis numbers for the vertical axis (ex. $50, $100, etc.). • Make sure the scale on your vertical axis does not change. If, for example first gridline jumps from $0 to $50, then next gridline needs be $100. After than comes $150, $200, etc. Note that I am talking about the gridlines here, not the axis labels. I don’t have spaces to put an axis label for every gridline. • Use as much of the graph as possible without changing your scale. i.e. Figure out the highest level of income you need to plot for each chart, then pick a scale that best fits that number. i.e. Don’t make your graphs really, really, short. • Label each curve (ex. “2% growth rate”, 3% growth rate”). • You do not have to plot every single year. However, the more precise points you have the better. 2 ECON 10233 Introduction to Macroeconomics 3 John Lovett ECON 10233 Introduction to Macroeconomics John Lovett Questions 18–20: Assume Narnia’s Real GDP/capita is currently $5,000.
