Demand condition:
- Middle income group countries relatively exhibit the features
of developed countries. These countries have satisfactory level of
infrastructure.
- Hence, Aggregate Demand (AD) plays crucial role in deciding the
level of economic activities.
- Rise in the demand for output automatically leads to the more
investment in capital goods and technological development.
- Fall in demand holds back investment on these capital goods and
technological development.
Supply condition:
- But here supply side can not be neglected while studying
overall capital investment and technological development. These
countries do not have sufficient capital base either. These
countries are dependent on developed countries. Thus, supply side
also influence level of technological progress and production of
capital goods.
To conclude, we can not squarely be dependent
on demand side for technological progress and production of capital
goods. Hence, Supply side should also be considered.
