National income, growth & inflation

Answer: (c) the opportunity cost is transferred from the consumers of the product to the tax-paying public.

Free public provision does not remove the cost. The resources used still have other uses, and the bill is met through the government budget, which taxes help to fund, so the burden moves from the user to the tax-paying public.

• ✓ (c) When goods are provided publicly, they are financed through the budget and users pay nothing directly. Tax revenue is an important part of budget receipts, so taxpayers bear the cost that consumers would otherwise have paid.
• ✗ (a) Opportunity cost is what is given up when resources are used for one purpose instead of another. Producing the commodity always uses scarce resources, so the cost cannot be zero.
• ✗ (b) The cost is not ignored in economics. It has only moved from the consumer to someone else.
• ✗ (d) The government pays for the commodity out of the budget, which is funded mainly by receipts such as taxes. The burden therefore falls on taxpayers, not on the government as a separate bearer.

Remember · Free to the user is not free to society: public provision shifts the cost from the consumer to taxpayers through the budget.

Answer: (c) poverty and unemployment increase.

Rising GNP and per capita GNP show growth, but development also needs the gains to reach people. If poverty and unemployment increase, the income growth has not improved living standards, so it does not signal a higher level of development.

• ✓ (c) Development is wider than income growth. NCERT notes that even countries with high growth saw poverty rise quickly because the gains were shared unequally. Growth with rising poverty and unemployment is not development.
• ✗ (a) The balance between industry and agriculture affects the structure of the economy but says nothing about whether people are better off.
• ✗ (b) Industry growing faster than agriculture is a normal feature of structural change and does not by itself deny development.
• ✗ (d) Imports growing faster than exports widens the trade deficit. It is a balance-of-payments concern, not a test of whether GNP growth means development.

Remember · Growth (GNP, per capita income) is not the same as development. Rising poverty and unemployment show that growth has not turned into development.

Answer: (c) 2 and 4

Human capital formation means building up the knowledge, skills and capacities of people, and what is built is intangible. So statements 2 and 4 describe it, while accumulating capital or tangible wealth describes physical capital.

• ✗ 1. Accumulating more capital, in the sense of money or assets, is physical capital formation. Human capital formation is about improving people themselves.
• ✓ 2. Human capital is the specialised skills, knowledge and abilities that people bring to work. Investment in education, health and training raises them.
• ✗ 3. Tangible wealth such as machines or buildings is physical capital, which can be sold in the market like a commodity.
• ✓ 4. Human capital is intangible: it is built into the body and mind of its owner and cannot be separated from that person.

Remember · Physical capital is tangible and separable from its owner. Human capital (skills, knowledge, health) is intangible and inseparable from its owner.

Answer: (d) high capital-output ratio

A high capital-output ratio means that a lot of capital is needed to produce each extra unit of output. Even with high saving and investment, growth then stays low because each unit of capital adds little to output.

• ✓ (d) The incremental capital-output ratio (ICOR) links investment to growth: roughly, the investment rate divided by the growth rate. India's Ninth Plan invested more than the Eighth yet grew more slowly, so its ICOR rose from 3.43 to 4.53.
• ✗ (a) Weak administration can hinder projects, but it is not the measure that ties capital formation to output. It shows up through a high capital-output ratio.
• ✗ (b) Illiteracy affects human capital and productivity in general. It is not the standard reason why saving and investment fail to raise output.
• ✗ (c) Population density is a demographic feature, not a measure of how efficiently capital is turned into output.

Remember · Growth = investment rate divided by ICOR. A high capital-output ratio means investment is inefficient, so high saving does not give proportionate output.
