- Use a growth rate of 1.3% to predict the population in 2042 of a country that in the year 2006 had a population of 400 million. Use the approximate doubling time formula.Over the past year, in a given country, labor productivity (measured in hours worked) has increased by 5%; the total number of hours worked has remained the same; the number of workers increased by 5%, while the general population increased by 3%. Given this information, what is the approximate growth in the standard of living of this countryA population grows according to an exponential growth model. The initial population is P0=17P0=17, and the growth rate is r=0.3r=0.3.
- Use this method, Exponential decline model, to solve ( in petroleum economics) The production of the oil well decline exponentially, the initial flow rate is 1500 STB/day, the production rate of this well become 120 STB/day in the fourth year, find the production rate after 25 months from the beginning, find yearly production and production rate for this well for the next 4 years?In the midyear of 2020, a country’s population is 109,581,078 with a growth rate of approximately 1.35% per year. What will be the country’s population in 2050? 146,925,239 146,925,293 164,295,239 146,295,239In 2011 a country had a population of 119 million and a growth rate of -0.638%. Assuming that this rate remains constant, estimate the population of the country in 2025.
- Only answer the 2nd MCQ question of the growth rate of output per capitaIn 1960 GDP per capita in the Republic of Korea (constant 2015 US$) was $1027. In 2021 it was $32731. Calculate the growth rate of real GDP per capita in the Republic of Korea over this period. Now suppose that the Republic of Korea grows at the same rate for the 70 years following 2021. What will the Republic of Korea real GDP per capitae in the year 2091? Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.At mid-year 2018, the annual growth rate in Pakistan was 1.4%. What is your estimate of the per capita rate of change in Pakistan in 2018? Estimate the doubling time (in years) of this population (note: you may round the value for ln(2) = 0.7). What assumptions are required to make this doubling time estimation?
- Assume a model economy with the following parameters: C= 100+0.25Yd I=100+0.5Y-3000i G=125 T=100 (M/P)d= 6Y-24000i (M/P)s=4500 Derive the IS and LM relationHow large will Canada’s GDP be in 25 years? The answer depends on what the rate of growth in GDP will be over that 25-year period. A mathematical formula we can use for this calculation is the following: GDP2041 = GDP2016 (1 + g)25 where GDP2041 is the level of GDP in the year 2041, GDP2016 is the level of GDP in the year 2016, and g is the rate of growth in GDP. Assume that GDP in 2016 is $1000 million and assume that the value of g is 0.035 (3.5 percent per year). What will be the value of GDP in 2041? Now suppose that the value of g is 0.040 (4.0 percent per year). What will be the value of GDP in 2041 given this slightly larger rate of growth? What does this result say about the importance of policies that promote even slightly faster rates of growth in GDP?Logarithms are especially useful for comparing series with two divergent scales since 10 percent growth always looks the same, regardless of the starting level. When absolute levels matter, the raw data are more appropriate, but when growth rates are whats important, log scales are better.
