# Real GDP per person in Northland is $30,000

Question 1

Real GDP per person in Northland is $30,000, while real GDP in Southland is $10,000. However, Northland’s real GDP per person is growing at 1 percent per year and Southland’s is growing at 3 percent per year. If these growth rates persist indefinitely, then

Answer

Northland’s real GDP per person will decline until it equals Southland’s.

Northland’s real GDP per person will always be greater than Southland’s.

Southland’s real GDP per person will always be the same as Northland’s.

Southland’s real GDP per person will eventually be greater than Northland’s.

Question 5

Consider the country of Solow, which is described by the Solow-Swan model. Let the saving rate q = 0.8; let the population growth rate n = 0.05; let the rate of depreciation d = 0.05. If per capita income y = 100 and the per capita stock of capital k = 800, then:

Answer

replacement investment is 60, saving is 80 and k will decrease towards the steady state per capita capital stock.

replacement investment is 80, saving is 80 and k is at the steady state per capita capital stock.

replacement investment is 80, saving is 60 and k will decrease towards the steady state per capita capital stock.

replacement investment is 80, saving is 60 and k will increase towards the steady state per capita capital stock.
