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? real gdp per capita rose from 2020 to 2023 as population increased. real gdp per capita fell initially but eventually rose as population continued to expand. real gdp per capita fell from 2020 to 2023 as population increased. real gdp per capita rose initially but eventually fell as population continued to expand. the english economist thomas malthus made an incorrect prediction regarding long-run living standards. his error can largely be traced to his not recognizing the importance of .
