Factors that influence productivity and therefore growth are:
physical and human capital per worker and technological advances.
more government intervention in the marketplace.
increased consumption and less investment spending.
Historically, development of a new technology often:
results in immediate increases in productivity.
leads to increases in productivity only once firms learn how to use it.
requires a complementary increase in physical and human capital.
has had no impact on changes in productivity.
raises total factor productivity.
is not as important as infrastructure maintenance.
shifts the aggregate production function downward.
relies on consumption increases at the expense of saving.
Diminishing returns to physical capital suggests that:
when the amount of human capital per worker and the state of technology are
fixed, successive increases in the amount of physical capital per worker lead to
smaller increases in productivity.
physical capital increases lead to drops in productivity when the amount of human
capital per worker and the state of technology are fixed.
increases in technological progress lead to decreases in productivity.
physical capital must be increased less than human capital and technological
progress for growth to occur.
Diminishing returns to physical capital suggests that:
at some point, increasing the amount of physical capital per worker is not worth the
cost of the additional amount of capital.
after some point, increasing the amounts of physical capital per worker will lead to
decreases in productivity.
increasing the amount of physical capital per worker is always worth the cost of the
capital.
there are increasing returns to technology and human capital.
