Answer:
Minus
Explanation:
Gross Domestic Product (GDP) is the aggregate of the market value of all the final goods and services produced in an economy in a given period.
Gross National Product( GNP): measures the market value of all the final goods and services produced by the citizens (nationals) of a country irrespective of where they reside. Also, incomes generated by foreigners are subtracted from the aggregate because they are not nationals.
GNP= GDP + Incomes earned by nationals from abroad - Incomes generated by foreigners
Net National Product (NNP) ; This accounts for the total value created in the economy after the depletion in capital has been accounted for. Production activities result in consumption and depletion in capital stocks (machines, roads and other infrastructures). To ensure that the economy restores its stock of capital after the accounting period, an amount for capital consumption is deducted from the aggregate income. It is called capital allowance or depreciation.
NNP= GNP - Depreciation
National Income (NI) aggregates all the incomes earned by all the economic agents in the economy. Using the expenditure approach, it is the case that money received by firms for the exchange of their goods and services are usually inclusive of consumption taxes- indirect taxes. These taxes are not part of the incomes earned by the firms, rather they are remitted to the government.
So indirect taxes are deducted from the aggregate to arrive at the National Income
