SECTION B

a) When will an increase in national income indicate an improvement in the standard of living for a country?
An increase in national income indicates an improved standard of living if it leads to an increase in per capita income, meaning national income grows faster than the population. It also requires a more equitable distribution of income so that the benefits are widely shared. Furthermore, the increase must be in real terms (adjusted for inflation) and reflect an increase in the availability of goods and services that genuinely enhance welfare, rather than just military spending or environmental cleanup.

b) How can the problem of double counting be eliminated when measuring national income?
The problem of double counting can be eliminated by using the value added method, which sums only the value added at each stage of production. Alternatively, the final output method counts only the value of final goods and services, excluding intermediate goods. The income method also avoids double counting by summing all factor incomes (wages, rent, interest, profit), as each factor's contribution is counted only once.
