3.About the “Double Counting”
n Final goods: the product that is produced and sold for consumption or investment.
n Intermediate goods: goods that are used up to produce other goods.
Q=real GDP=Nominal GDP/GDP Deflator

Example: GDP by income side
经济学原理2(1)
1)Flow-of-product Approach
n In this measure, we only calculate the final products, not intermediate goods (avoiding double counting). If we add all the consumption spent on the final goods and services, we’ll get the two-partmode’s GDP. (as the figure: the upper loop)
n Gross Investment: the investment includes all investment goods produced. (includes depreciation which is the amount of capital that has been used up in a year)
经济学原理2(1)
7) GDP, NDP, GNP
n GDP: Gross Domestic Product, the market value of all final products and services produced in a nation during one year. It includes gross investment.
n NDP: Net Domestic Product. (GDP-Depreciation)
n GNP: Gross National Product.
经济学原理2(1)
conclusion
n Goods Flow (upper loop): GDP=C+I+G+X
n Earnings Flow (lower loop): GDP=Wage or other income+ Interest, Rent or other property income+ indirect taxes+ depreciation+ profit
n The result by the two ways is equal.
经济学原理2(1)
Some Examples
经济学原理2(1)
8) From GDP to DI
n GDP=total incomes by different factors+ indirect taxes+ depreciation
n Investment means the additions to the nation’s capital stock of building, equipment and inventories during a year. From the figure, the investment is the part of upper-loop output which is not consuming. The saving means the part of the lower-loop disposable income (or GDP) that is not spent on consumption. (assume: two-part-economy)

3) Equivalence of the two approach
The results by the two approaches are equal. Why?
* National accounts derived from business accounts. (P.392)

n Imports means the foreign countries provide goods and services to the nation.

6) Total national investment
Total national investment: I+X Total net national investment Net foreign investment (net exports)
2. Two measures of national output
1) Flow-of-product Approach (goods flow) 2) Earnings or cost Approach (earnings flow) 3) Equivalence of the two approaches
经济学原理2(1)
2)Investment and capital formation
n Investment: the additions to the nation’s capital stock of buildings, equipment and inventories during a year.
经济学原理2(1)
5) Net Exports
n Net exports: the difference between exports and imports of goods and services.
n Exports means the nation provides the goods and services to other nations.

4) Taxes
n Direct taxes n Indirect taxes
When we calculate GDP in the flow-of – cost way, we must add the indirect tax into the GDP.
经济学原理2(1)
2) Earnings or costs approach
n The businesses must pay for the productive inputs: wage, rent, profit, etc. These we call the cost the business must expend. The cost are also the earnings the households receive from the business. Add all the cost we’ll get the total GDP. (as the figure: the lower loop)
