We will assume that everyone in this country works so that population equals employment and per-person GDP equals per-worker GDP.

The following tables show the supply of land, population size, and real GDP for these two economies from 2020 to 2023.

The experts predict that the growth ofthe economy of Country X will gradually slowdown in the coming years. Moreprecisely, they foresee the following growth rates for the future:2007 – 2010 = 10%2010 – 2013 = 9%2013 – 2016 = 7.5%2016 – 2019 = 5%2019 – on = 1% Hint: The list above should be read as saying that, for instance, the growth rate fromthe end of the fiscal year 2007 until the end of 2010 will be 10 %, then from the end of2010 until the end of 2013 it will be 9% and so on. Assuming that the predictions of the experts listed above are accurate, when in thefuture will Country X’s GDP double compared to the GDP level of 2007? Consider now the more optimistic scenario in which the economy does not slow downand the current growth rate of 10% remains constant in the coming years. How longwill it take for the GDP level to double in this scenario? Express…arrow_forward
