To achieve high rates of growth of national output, the economy has to
Options:
A .  borrow foreign capital
B .  reduce the rate of growth of population
C .  step up the rate of savings
D .  increase the rate of investment and reduce the capital output ratio
Answer: Option D Answer: (d) The immediate effect of devoting a larger share of national output to investment is that the economy devotes a smaller share to consumption; that is, “living standards” as measured by consumption fall. The higher investment rate means that the capital stock increases more quickly, so the growth rates of output and output per worker rise. According to Smith, in a developing economy, both income level and capital stock rise. In addition to this, the rate of capital accumulation also shows a tendency to increase. This leads to an increase in the capital stock in successive periods as investment keeps on increasing. Another important factor that contributes to the progress of an economy is the successive decline in the incremental capital-output ratio due to the influence of capital on the productivity of labour.
