Estimate the value of the growth rate of real
(a)
Explanation of Solution
The growth rate of real GDP:
The growth rate of real GDP can be calculated using the following formula:
The growth rate of real GDP:
If the 2016 real GDP is 14,461 billion and 2017 real GDP is 14,702 billion, then the value of the growth rate of real GDP can be calculated using the following formula:
Thus, the value of the growth rate of real GDP is 1.7%.
(b)
Estimate the value of the growth rate of real GDP per person.
(b)
Explanation of Solution
Country M’s population growth:
If country M’s population in 2016 is 121 million and 122 million in 2017, then the population growth rate can be calculated using Equation (1) as follows:
Thus, the value of Country M’s population growth rate is 0.8%
Growth rate of real GDP per person:
The growth rate of real GDP per person can be calculated as follows:
Thus, the value of the growth rate of real GDP per person is 0.9%.
(c)
Estimate the approximate number of years to double the real GDP.
(c)
Explanation of Solution
The approximate number of years to double the real GDP can be calculated as follows:
Thus, the approximate number of years to double the real GDP per person is 77.8 years.

- In 1980, Denmark had a GDP of 70 billion (measured in U.S. dollars} and a population of 5.1 million. In 2000, Denmark had 3 GDP of 160 billion (measured in U.S. dollars} and a population of 5.3 million. By what percentage did Denmarks GDP per capita rise between 1980 and 2000?arrow_forwardSuppose China’s GDP is growing by 7% a year and its population grows by 1% a year. Also suppose that US GDP grows by 3% a year and its population grows by 1% a year, and that in 2019 US GDP is 1.5 times China’s while US population is one quarter of China’s. If these growth rates continue By what year will China’s GDP double? Its population? Its per capita GDP?In what year will China’s GDP equal US GDP?In what year will China’s GDP per capita equal US GDP per capita?arrow_forwardAustralia's real GDP was $A1,730 in 2017 and $A1,782 in 2018.

- There is a chart for quesition 2 that is attached as an image. Suppose that work hours in New Zombie are 200 in year 1 and productivity is $8 per hour worked. What is New Zombie’s real GDP? If work hours increase to 210 in year 2 and productivity rises to $10 per hour, what is New Zombie’s rate of economic growth? Explain why sustained long-term economic growth comes from increases in labor productivity. Why do you think the trend rate of U.S. productivity growth has increased since the earlier 1973–1995 period? Hint: The quantity of labor and increases in labor productivity are important sources of economic growth. Between 1953 and 2015, in the US economy the labor force increased from 63 million to 158 million workers. Productivity growth has usually been the more significant factor. To calculate real GDP in a given year you have to multiply hours worked by productivity. 2. Suppose that New Zombie has adopted the framework used by the US Bureau of Labor Statistics to calculate its…arrow_forwardSingapore's real GDP was 412 billion dollars in 2016 and 429 billion dollars in 2017.
