Proposal writing on the topic. Factors influencing the attitudes of SHS students towards the learning of economics.


Instructions : Answer true or false and explain the answer

(1) Suppose s = 0.15, Y = 4200, K = 6100, n = 0.03, g=0.03 and δ= 0.10. This makes national saving smaller than steady-state investment, so that the amount of capital per effective worker will be falling.

(2) In the Solow growth model, given the values of A=120, s=0.11, n=0.03, g=0.07, and δ=0.08, the economy has an equilibrium growth rate of real GDP per effective labour, (Y/AL), equal to 8 percent.

(3) In the graph of the Solow growth model, at any point to the left of the steady-state intersection we have national saving per effective labour greater than steady-state investment per person, causing (K/AL) to increase.

(4) In the Solow growth model, an increase in the marginal propensity to consume shifts the steady-state investment line downward with the implied change in the capital stock resulting in a higher standard of living in the long run.
Instructions : Answer true or false and explain your answer

(1) If an economy can raise its annual real GDP growth rate from 3.8 percent to 4.5 percent, its real GDP doubling time is reduced by 15 years.

(2) Suppose that the government passes a law requiring households to increase savings 10% above previous levels. According to Solow's growth theory, in the long run output per capita will grow less rapidly.

(3) If an economy has a real GDP doubling-time of 48 years, this will be increased to 56 years if annual GDP growth is reduced by 3.2 percentage points.

(4) If K = 3000, n = 0.02, and depreciation, δ= 0.04 and g =0.03, then investment of 320 will hold (K/AL) constant.
