A mathematical approximation called the rule of 70 tells us that the number of years that it will take something that is growing to double in size is approximately equal to the number 70 divided by its percentage rate of growth. Thus, If Mexico's real GDP per person is growing at 7 percent per year, it will take about 10 years (= 70/7) to double. Apply the rule of 70 to solve the following problem. Real GDP per person in Mexico in 2005 was about $12,000 per person, while it was about $48,000 per person in the United States.

Q5 Suppose in a Solow model, we have the following parameter values: n = 0, s = 0.5, a = 0.3. There is no growth in the total factor productivity so that A, = A = 1. Moreover, we know that at time 0, the economy is at a steady state so that k = k, =1. Now imagine that a foreign power invaded this %3D country. 1% of the population was killed and another 14% of the population fleeded the country to avoid violence. Moreover, 15% of capital stocks were destroyed. All of this happens in period t=1. After that, the war ended and there was no more destruction of capital or loss of population (but the refugee permanently settled outside of the country and will never return0. What is the growth rate of per-capita output in period t =4?
The following table shows the GDP per capita since 1820 in selectedcountries (in PPP-adjusted 2005 dollars). 1. Identify the countries that experienced sustained growth from 1920 to2010.
This question pertains to correctly calculating total investment as a percent of GDP for a country across multiple years with different amounts of investment per year and different GDPs per year. I've seen 2 methods to calculate the total investment as a percent of GDP for 1 country. First, for each year, calculate investment as a percent of GDP for each year then sum those percentages. Second, sum all investments and sum all GDP across years and then divide sum of investments over sum of GDP. What is the correct method to calculate total investments across multiple years for 1 country when each year has a different GDP?
11) The relationship between the growth rate of an economic variable, gt, and its level, yt, can be approximated by A) gt = yt - yt - 1. B) gt = logt - log yt - 1. C) yt = log gt - log gt - 1. D) log gt = yt - yt - 1. 12) The business cycle component of the log of real per-capita GNP is equal to A) log of actual real GNP - log of trend GNP. B) log of trend GNP ÷ log of actual real GNP. C) log of trend GNP - log of actual real GNP. D) log of actual real GNP ÷ log of trend GNP. 13) For the study of economic growth, it is most helpful to examine movements in ________; for the study of business cycles, it is most helpful to examine movements in ________. A) trend GNP; trend GNP B) trend GNP; deviations from trend in GNP C) deviations from trend in GNP; trend GNP D) deviations from trend in GNP; deviations from trend in GNP 14) Over the twentieth century, growth in per-capita GNP was highest A) immediately prior to the Great…

China's economic growth in 2015 is slowest in 25 Years China's growth rate slowed to an annual rate of 68 purcent in the fourth quarter of 2015, down from 73 percent in 2014 China's growth rate has slowed from 7.3 percent a year in 2014 and if it remans at 6.8 percent a year, how many additional years will it take for China's real GDP to double When real GDP per person grows at 73 percent a year, real GDP per person in China doubles in years >>> Answer to 1 decimal place.
Suppose the 50% of the income generated by an economy is paid to workers, thus implying that the remaining 50% is paid to capital. If GDP grew by 4%, capital grew by 1%, and labor grew by 3%, then what was the growth rate in technology? (Record your answer as a whole number, and do not include a "%".)
The GDP of South Africa in 1950 was 77,836.88 million dollars. In 2019 it was 748,861 million dollars. What has been the annualized growth rate of GDP for South Africa during the period 1950 to 2019? Use growth compounding to calculate the number and write the answer in percent terms with up to two decimals (e.g., 10.22 for 10.22%, or 2.33 for 2.33%).
In 2020, the GDP was approximately $20 trillion. If GDP is expected to double in 20 years, what is the expected growth rate per year?
In 2018, India was the world’s seventh largest economy, with a $2.69 trillion GDP (as measured in U.S. dollars). India was also one of the world’s fastest-growing economies, with an annual growth rate of real GDP of 7.3%. a. If the country maintains the same growth rate, how many years will it take for India’s GDP to double? b. Bangladesh’s GDP was $286.27 billion, but its growth rate was equal to India’s. How many years will it take for Bangladesh’s economy to double? c. Although Bangladesh and India have the same annual growth rate, their economies are much different in size. How can you explain the size difference to someone who is unfamiliar with scaling large numbers? Which strategies would you use?
Economic growth around the world The following table reports real income per person for several different economies in the years 1960 and 2010. It also gives each economy's average annual growth rate during this period. For example, real income per person in Niger was $945 in 1960, and it actually declined to $570 by 2010. Niger's average annual growth rate during this period was -1.01%, and it was the poorest economy in the table in the year 2010. The real income-per-person figures are denominated in U.S. dollars with a base year of 2005. The following exercises will help you to understand the different growth experiences of these economies. Economy Real Income per Person in 1960 Real Income per Person in 2010 Annual Growth Rate (Dollars) (Dollars) (Percent) Canada 12,946 35,810 2.06 United Kingdom 11,884 32,034 2.00 Korea 1,610 28,702 5.93 Hong Kong 4,518 44,070 4.66 Guatemala 1,985 3,859 1.34 Niger 945 570 -1.01 Indicate which economy…
