Grade 11 Economics: Chapter 3- Lesson 3.3.1

What is the core definition of the Expenditure Approach to measuring GDP?

It involves calculating GDP by adding up the total amount of money spent by buyers on all final goods and services produced in the economy over a given period of time.

In national income accounting, what is the difference between a final good and an intermediate good?

Final Good: A good or service in the hands of the final user or ultimate consumer (e.g., orange juice or a mobile phone).

Intermediate Good: A good used entirely as an input in the production of another good (e.g., oranges bought by a juice factory).

What are the four major expenditure components added together to calculate GDP?

1. Personal Consumption Expenditure (C)

2. Gross Private Domestic Investment (I)

3. Government Purchases (G)

4. Net Exports (NX)

What is the full mathematical equation for GDP using the expenditure approach?

$$\text{GDP} = C + I + G + NX$$

What does Personal Consumption Expenditure ($C$) represent, and what is its typical size relative to other components?

It represents the total spending by households on final goods and services. It typically takes the "lion's share" (the largest component) of total GDP.

In macroeconomic accounting, what is the difference between a flow measure and a stock measure?

Flow Measure: A variable measured over a specific interval or period of time (e.g., annual income or spending).

Stock Measure: A variable measured at a specific single point in time (e.g., total wealth or total government debt).

Classify "A person's wealth" and "A person's income/expenditure" as either a stock or a flow measure.

Wealth = Stock measure

Income/Expenditure = Flow measure

Classify "The amount of capital in the economy" and "The amount of investment" as either a stock or a flow measure.

Amount of Capital = Stock measure

Amount of Investment = Flow measure

Classify "The government debt" and "The government budget deficit" as either a stock or a flow measure.

Government Debt = Stock measure

Budget Deficit = Flow measure

What is the definition of Net Exports (NX), and what is its alternative name?

Net Exports is the difference between total exports (X) and total imports (M). It is also referred to as the "trade balance".

What is the formula used to calculate Net Exports (NX)?

$$NX = X - M$$

In national accounts, what do Exports (X) and Imports (M) strictly represent?

Exports (X): Purchases of domestically-produced goods and resources made by foreign residents, firms, or governments.

Imports (M): Purchases made by domestic citizens/residents from foreign countries.

What does a positive Net Export value mean versus a negative Net Export value?

Positive NX: Exports are greater than imports ($X > M$), meaning a trade surplus.

• Negative NX: Imports are greater than exports ($M > X$), meaning a trade deficit.

Why are transfer payments (like government pension checks or welfare payments) excluded from the Government Purchases (G) component of GDP?

Because GDP only tracks expenditures that represent new, active production of goods and services. Transfer payments do not buy a current good or service; they are just a redistribution of income.
