    • The effect of National income on economic welfare an be studied in two ways
    • The change in the size of National Income: Positive change in NI increases its volume, as a result people consume more of goods and services, which leads to increase in economic welfare and vice versa. This relationship depends on various factors.
    • Only real increase in national income increases economic welfare.
    • NI cannot be a reliable index if per capita income is not taken into account.
    • Sometimes even with increase in NI and Per capita income economic welfare decreases due to unequal distribution of economic wealth.
    • Influence of increase in National Income on economic welfare also depends on the spending habit of the consumers.
    • The change in distribution of National Income
    • Change can be from rich to poor and from poor to rich and economic welfare is said to increase when former situation is implemented.
