Notes

Why We Need Aggregates

National Income is a crucial concept in macroeconomics. It is measured using various aggregates or variants, each with a specific meaning, measurement method, and use.

We cannot simply add 5 kg of rice + 3 metres of cloth + 2 hours of service. Quantities of different goods cannot be added directly. By converting everything to monetary value, we get a common unit to measure the economy's total output.

The eight primary aggregates of national income are:

GDP_MP

Gross Domestic Product at Market Price

GrossMP

GDP_FC

Gross Domestic Product at Factor Cost

GrossFC

NDP_MP

Net Domestic Product at Market Price

NetMP

NDP_FC

Net Domestic Product at Factor Cost (Domestic Income)

NetFC

GNP_MP

Gross National Product at Market Price

GrossMP

GNP_FC

Gross National Product at Factor Cost

GrossFC

NNP_MP

Net National Product at Market Price

NetMP

NNP_FC

Net National Product at Factor Cost (National Income)

NetFC
NDP_FC is called Domestic Income and NNP_FC is called National Income — these are the two most important aggregates in this chapter. ⭐

Three Dimensions of Classification

The eight aggregates can be understood through three independent dimensions. Each dimension cuts the eight into two groups of four. Combining all three gives you all eight.

GDP_MP

Gross Domestic Product at Market Price

GrossMP

GDP_FC

Gross Domestic Product at Factor Cost

GrossFC

NDP_MP

Net Domestic Product at Market Price

NetMP

NDP_FC

Net Domestic Product at Factor Cost (Domestic Income)

NetFC

GNP_MP

Gross National Product at Market Price

GrossMP

GNP_FC

Gross National Product at Factor Cost

GrossFC

NNP_MP

Net National Product at Market Price

NetMP

NNP_FC

Net National Product at Factor Cost (National Income)

NetFC
Each dimension is independent. Domestic vs Nationalasks “who produced it?” Gross vs Netasks “did we account for wear and tear?” Market Price vs Factor Costasks “are taxes included?”
