GDP and Welfare

Correct answer: A. It does not fully show the distribution of income

Per capita income is calculated by dividing national income by the population, so it represents an average income. An average can conceal substantial inequality: two countries may have the same per capita income even though income is evenly distributed in one and concentrated among a small group in the other. Therefore, option A is correct.

Correct answer: A. Because total income alone does not clearly show equality or inequality

National income is an aggregate total and does not show who receives that income. Two countries may have the same average income while one has a more unequal distribution. Examining distribution therefore helps evaluate equity, poverty, living standards, and whether economic growth benefits broad sections of society.

Correct answer: A. Demand management through fiscal policy

Taxes are a fiscal policy instrument. A reduction in taxes can increase households’ disposable income, encourage consumption and raise aggregate demand, although the final effect depends on how people use the additional income. Because the policy targets economy-wide demand and activity, it is a macroeconomic example of fiscal demand management.

Correct answer: C. Because they show total economic activity from different viewpoints

In national income accounting, the value of production creates income for factors of production, and that income supports expenditure on final goods and services. Therefore, output, income and expenditure are three perspectives on the same circular flow of economic activity. With proper adjustments, their measured totals should be equal.

Correct answer: D. The effect on per capita income and standard of living

Per capita income is calculated by dividing total income or output by population. If total output remains unchanged while population increases, output and income per person tend to fall, unless distribution or other income sources change. Therefore macroeconomic analysis examines possible effects on average living standards, consumption capacity, and welfare.

Correct answer: A. Total output does not fully show every aspect of welfare

GDP and related output measures record market production, but they do not fully capture environmental degradation, unpaid work, inequality, leisure, or the quality of life. Production may rise while pollution and resource depletion reduce welfare. Therefore macroeconomic aggregates are useful indicators of activity, but they should be supplemented with environmental and social measures.

Correct answer: A. They may not fully show income distribution and quality of life

National income data are valuable indicators of economic activity, but they do not provide a complete measure of welfare. A high national income may coexist with severe inequality, poverty, pollution, unpaid household work or poor access to health and education. Therefore, distributional and social indicators are also needed for evaluation.

Correct answer: A. National income does not fully show non-market activity and distribution

National income indicates the monetary value of recorded production and income, so it is related to welfare but not identical to it. It may omit unpaid household services, informal activity and environmental costs, and it does not show distribution. Welfare also depends on health, education, security, leisure and quality of life.

Correct answer: B. To avoid double counting

Intermediate goods are used to produce other goods. If their full value and the full value of the final product were both counted, part of the same production value would be counted more than once. Counting final goods, or adding value added at each production stage, avoids this double counting.

Correct answer: D. The relationship between the external sector and national income

Exports are domestic goods and services purchased by the foreign sector. Other things being equal, higher exports increase external demand for domestic output and can raise firms' sales, production and demand for labour. This illustrates how the external sector can affect domestic output, employment and national income.

Correct answer: A. Because averages can hide inequality and distribution

An average, such as per capita income, is calculated by dividing an aggregate by the number of people. It may rise even when most people receive little benefit, because a small group can capture a large share of income. Thus, averages do not fully reveal inequality, poverty, or distribution. Option A correctly states this limitation and relates to GDP and welfare.

Correct answer: C. An aggregate average does not fully reveal individual welfare

An increase in national income or average income does not prove that every person is better off. A large share of the additional income may go to a small group, while poorer households receive little benefit. Thus, aggregate measures can conceal inequality and cannot fully represent individual welfare. Option C is correct.

Correct answer: A. Because income distribution can be unequal

Per capita income is only an average: it divides total income by the population. The average may rise because income gains are concentrated among richer households, while poor households receive little or no increase. Poverty can therefore persist despite higher average income. A complete assessment also considers distribution, employment, prices, and access to basic services. Option A is correct.

Correct answer: C. National income does not fully show distribution, environment, and non-market activities

National income is an important indicator of economic activity, but it is not a complete measure of welfare. It may rise while income becomes more unequal, environmental damage increases, leisure declines, or unpaid household and community work remains unrecorded. It also does not directly measure health, security, freedom, or quality of life. Therefore C is correct.

Correct answer: A. Average income can hide inequality of distribution

Per-capita or average income is calculated by dividing total income by population. It gives a useful summary, but it does not show how income is distributed among people. A high average can coexist with severe inequality, poverty or exclusion, so distributional indicators must be examined alongside the average.

Correct answer: C. Because both affect national stability and welfare

Inflation reduces the purchasing power of money and creates uncertainty for households and firms. Unemployment reduces income opportunities, production and economic security. Since both are economy-wide outcomes and central policy objectives, policymakers monitor them together while considering possible trade-offs and the effects on national welfare.

Correct answer: A. It can conceal the effects of poverty and inequality and make average income appear more beneficial than it is for different groups.

Macroeconomic indicators such as national income or GDP usually report aggregate or average outcomes. They do not show how income is divided among households. If distribution is ignored, a rise in average income may coexist with severe poverty, inequality or weak purchasing power among lower-income groups. Such an analysis can lead policymakers to overestimate welfare and choose policies that do not reach vulnerable sections. Hence, distributional information is essential for sound welfare and policy conclusions.

Correct answer: B. Income distribution, environmental quality, and non-market services also matter

Correct answer: B. National income measures the monetary value of income or production, but economic welfare is broader. A rise in income may occur alongside greater inequality or environmental damage, and many non-market services, such as unpaid household work, are not fully reflected in national income. Therefore, national income alone cannot establish that welfare has improved.

Correct answer: D. Total output does not capture every aspect of welfare

The correct answer is D. Measures such as GDP record economic production, but they do not fully capture environmental quality or all the costs of environmental damage. Output can rise even while pollution or resource depletion harms health and living conditions, so output alone is not a complete measure of welfare.

Correct answer: C. The total amount of income and its distribution are separate questions.

Aggregate national income measures the total income generated in an economy; it does not show how that income is distributed. Total income can rise even if the gains go mainly to a small group. Therefore, growth in total income and equality of distribution must be assessed separately.

Correct answer: A. Time period

A flow is measured over an interval, so its time period must be specified. Statements such as income per month, output during a year, or expenditure in a quarter are meaningful because they identify the interval of measurement. Units are also useful, but they do not distinguish a flow from a stock. Therefore, option A is correct.

Correct answer: B. Interest

Capital is a factor of production used by firms to produce goods and services. In the standard factor-income classification, the payment for the use of capital is interest. Wages are paid for labour and rent for land. A dividend is a distribution of company profit to shareholders, not the standard factor reward for capital services in this question. Therefore, option B is correct.

Correct answer: C. Profit

Entrepreneurship is the factor that organises other factors, makes production decisions, bears uncertainty and accepts business risk. The reward for providing these enterprise services is profit. Wages are the reward for labour, rent for land, and interest for capital. Therefore, option C is correct because profit corresponds to entrepreneurship.

Correct answer: A. Purchasing capacity

Factor payments such as wages, rent, interest and profit constitute income received by households for supplying factors of production. When firms reduce these payments, household income tends to decline. With less disposable income, households generally have a lower purchasing capacity and may reduce their consumption of goods and services.

Correct answer: A. Production costs

Wages and rent are factor incomes for households because households supply labour and land or property services. From the firms’ perspective, the same payments are expenses incurred to obtain and use these factors in production. Therefore, wages and rent are included in firms’ production costs. They are not household consumption expenditure, import payments or government grants. Hence, option A is correct.
