Question

Consider the economies of Sporon and Gribinez, both of which produce agricultural products using only land and labor. The following tables show the supply of land, population size, and real GDP for these two economies from 2020 to 2023. Calculate real GDP per capita for the two economies, and complete the last column of the following two tables.
Sporon
Year Land Population Real GDP Real GDP per Capita
(Acres)
2020 20,000 1,000 $15,000 $
2021 20,000 2,000 $28,000 $
2022 20,000 3,000 $36,000 $
2023 20,000 4,000 $40,000 $
Gribinez
Year Land Population Real GDP Real GDP per Capita
(Acres)
2020 20,000 500 $4,500 $
2021 20,000 1,000 $10,000 $
2022 20,000 1,500 $16,500 $
2023 20,000 2,000 $24,000 $
Rapid population growth tends to threaten economic growth in economies with land-to-labor ratios. Which of the following is a correct description of the effect of population growth on economic growth in Gribinez from 2020 to 2023?
a. *Real GDP per capita rose initially but eventually fell as population continued to expand.
b. *Real GDP per capita rose from 2011 to 2014 as population increased.
c. *Real GDP per capita fell in*Real GDP per capita fell from 2011 to 2014 as population increased.

Answer 1

Answer:

Sporon

2020 $15

2021   $14

2022  $12

2023  $10

Gribinez

2020 $9

2021  $10

2022  $11

2023  $12

Real GDP per capita rose from 2020 to 2023 as population increased.

Explanation:

Real Per capita GDP measures the standard of living of the people in a country. The higher the Real Per capita GDP, the higher the standard of living

Real Per capita GDP = Real GDP / population

Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year

GDP calculated using the expenditure approach = Consumption spending by households + Investment spending by businesses + Government spending + Net export

Real GDP is GDP calculated using base year prices. Real GDP has been adjusted for inflation.

Sporon

2020 : $15,000 / 1000 = $15

2021:  $28,000 / 2000 =    $14

2022 :  $36,000 /3,000 =  $12

2023: $40,000/4000 =  $10

Gribinez

2020  : $4500 / 500= $9

2021 : $10,000 / 1000 = $10

2022 $16,500 / 1500=  $11

2023: $24,000 / 2000 =  $12

The real GDP per capita of Gribinez rose from 2011 to 2014 as population increased because the rate of increase of real GDP per capita was higher than the rate of increase in population

Rate of increase of population in 2022 = (1500 / 1000) - 1 = 0.5 = 50%

Rate of increase in Real GDP in 2022 = (16500 / 10,000) - 1 = 0.65 = 65%
