In the economy of Cape Despair the subsistence real wage rate is​ $15 an hour. Whenever real GDP per hour rises above​ $15, the population​ grows, and whenever real GDP per hour of labor falls below this​ level, the population falls. The table shows Cape Despair's production function:

Labor (billions of hours per year) Real GDP (billions of 2000 dollars)
0.5 8
1.0 15
1.5 21
2.0 26
2.5 30
3.0 33
3.5 35

Initally, the population of Cape Despair is constant and real GDP per hour of labor is at the subsistence level of $15. Then a technological advance shifts the production function upward by 50 percent at each level of labor.

a. What are the initial levels of real GDP and labor productivity?
b. What happens to labor productivity immediately following the technological advance?
c. What happens to the population growth rate following the technological advance?
d. What are the eventual levels of real GDP and real GDP per hour of labor?

Final answer:

Initially, Cape Despair had a real GDP of $15 billion and labor productivity of $15 per hour. Post-technological advancement, labor productivity rises by 50%, leading to an increase in population growth rate. The eventual levels of real GDP and real GDP per hour will balance out at a higher subsistence level due to the productivity gains.

Step-by-step explanation:

To answer the question posed about the economy of Cape Despair, let's consider the initial levels of real GDP and labor productivity based on the provided production function, the effects of a technological advance, and its impact on population growth and real GDP per hour of labor.

Initial Levels of Real GDP and Labor Productivity

The initial level of real GDP is given as $15 billion, which occurs when labor is 1.0 billion hours per year, making labor productivity (real GDP per hour of labor) $15 per hour. This meets the subsistence real wage rate, indicating that initially, the population of Cape Despair is constant.

Labor Productivity Post-Technological Advance

Immediately following the technological advance, labor productivity rises by 50 percent at each level of labor. If we calculate this increase for the 1.0 billion labor hour mark, the new labor productivity figure would be $22.50 per hour (1.5 times the original productivity of $15).

Population Growth Rate After Technological Advance

With the increase in labor productivity above the subsistence level, the population growth rate will increase, as per the conditions described for Cape Despair's economy.

Eventual Levels of Real GDP and Real GDP Per Hour of Labor

Eventually, the levels of real GDP and real GDP per hour of labor will likely balance out at a new higher subsistence level. For example, if at the increased productivity rate the economy operates where labor is 1.0 billion hours, the new real GDP would be $22.50 billion, and the real GDP per hour would also be $22.50.

Answer:

new levels of real after 50% increase in gdp =

0.5 ----> 8(1+0.5) = 12 labour productivity = 12/0.5 = 25

1-----> 22.5 22.5/1 =22.5

1.5 21(1+0.5) = 31.5 31.5/1.5 = 21

2.0 26(1+0.5) = 39 39/2 = 19.5

2.5 30 = 45 45/2.5 = 18

3.0 33 = 49.5 49.5/3 = 16.5

3.5 35 = 52.5 52.5/3.5 =15
