THE INCOME METHOD:THE INCOME METHOD:
The Income method measures national income The Income method measures national income from the side of payments made to the primary from the side of payments made to the primary factors of production in the form of rent, wages , factors of production in the form of rent, wages , interest and profit for their productive services in interest and profit for their productive services in an accounting year .an accounting year .
Thus if factor incomes generated by all the Thus if factor incomes generated by all the producing units located within the domestic producing units located within the domestic economy during a period of account are added economy during a period of account are added up to, the resulting total will be Domestic income up to, the resulting total will be Domestic income or or Net Domestic Product at FC (NDP at FC)Net Domestic Product at FC (NDP at FC)

EXPENDITURE METHODEXPENDITURE METHOD :- :-Expenditure method measures final Expenditure method measures final
expenditure on Gross Domestic Product at expenditure on Gross Domestic Product at market price (GDP at MP) during a period of market price (GDP at MP) during a period of account .By adding up all the items of final account .By adding up all the items of final
consumption consumption expenditure and final and final investment expenditure within the domestic investment expenditure within the domestic
economy, we get the aggregate called GDP at economy, we get the aggregate called GDP at mp.i.e. why expenditure method is also mp.i.e. why expenditure method is also knows as' Consumption and investment knows as' Consumption and investment method' or' income Disposable method'. method' or' income Disposable method'.

MARGINAL PROPENSITY TO CONSUME (MPCMARGINAL PROPENSITY TO CONSUME (MPC))
The ratio of change in consumption(c) to change in The ratio of change in consumption(c) to change in income (Y) is called marginal propensity to consume. income (Y) is called marginal propensity to consume. literally marginal means additional (or incremental) and literally marginal means additional (or incremental) and
propensity to consume means desire ( or urge) to propensity to consume means desire ( or urge) to consume. thus consume. thus MPC is the ratio of additional consumption MPC is the ratio of additional consumption to to additional additional income. it indicates the proportion of income. it indicates the proportion of additional income that is additional income that is
being spent on additional being spent on additional consumption. consumption.
MPC =C/YMPC =C/Y
Hence, MPC is always greater than zero (MPC > 0)and less Hence, MPC is always greater than zero (MPC > 0)and less than 1(MPC < 1)because additional consumption (c) is less than 1(MPC < 1)because additional consumption (c) is less than additional income (y). thus value of MPC liesthan additional income (y). thus value of MPC lies between between

National income accounting calls for an understanding of the structure National income accounting calls for an understanding of the structure of the macro economy. A pictorial illustration of this inter-of the macro economy. A pictorial illustration of this inter-independence between the major sectors of economic activity is called independence between the major sectors of economic activity is called the circular flow of income and product. The circular flow of income the circular flow of income and product. The circular flow of income involves two basic principles:involves two basic principles:
a) In any exchange process, the seller or producer receive the same a) In any exchange process, the seller or producer receive the same amount that the buyer or consumer spends; andamount that the buyer or consumer spends; and
b) Goods and services flow in one direction and money payments to b) Goods and services flow in one direction and money payments to acquire these, flow in the return direction, thereby causing a cicular acquire these, flow in the return direction, thereby causing a cicular flow. So, the output or product or real flow from the seller to the buyer flow. So, the output or product or real flow from the seller to the buyer necessarily creates the income or payment or money flow from the necessarily creates the income or payment or money flow from the buyer to the seller.buyer to the seller.
