Final answer:
Developing countries heavily rely on foreign capital to bridge the gap caused by a lack of domestic savings, enabling increased investment and higher per capita incomes. Foreign capital is essential, often bringing expertise and technology that aid in economic development.
Step-by-step explanation:
Developing countries draw heavily on foreign capital primarily because foreign capital is a means to overcome a shortage of domestic savings, which enables them to increase investment and, subsequently, raise per capita incomes. Option (a) offers the correct reason for this phenomenon.
The ability of developing countries to self-generate sufficient investment capital is often limited, creating a gap that can be partially filled through foreign aid and international investment. Nevertheless, this foreign capital alone is not always sufficient for comprehensive capital accumulation, which is essential for investments in both physical and human capital.
These inflows are particularly important because they often bring not just the necessary financial resources, but also management expertise, technological know-how, and opportunities for training, which can contribute to economic growth and development.
While foreign aid and investment can have significant benefits, it is a controversial issue whether they always lead to economic growth. What is clear, however, is that low-income countries actively seek foreign investment to aid in developing their economies and to potentially achieve rapid economic growth.
