Takeaways

• 😀 National income can be calculated using two methods: the income method and the expenditure method.
• 😀 The income method uses the formula: Y = R + W + I + P, where R is rent, W is wages, I is interest, and P is profit.
• 😀 The expenditure method uses the formula: Y = C + I + G + X - M, where C is consumption, I is investment, G is government expenditure, X is exports, and M is imports.
• 😀 It’s essential to know which method to use based on the question, as using the wrong formula will lead to incorrect results.
• 😀 When using the income method, ignore irrelevant data and focus only on income-related information like rent, wages, interest, and profit.
• 😀 In the expenditure method, focus on data related to economic expenditure, such as consumption, investment, government spending, exports, and imports.
• 😀 Per capita income is calculated by dividing the national income by the population: per capita income = national income / population.
• 😀 The formula for national income using the income method is simple and involves adding up all the income components.
• 😀 Be careful with distinguishing between data for income and data for expenditure when using the expenditure method.
• 😀 The instructor advises to ensure the correct method is identified before starting the calculation to avoid confusion or errors.

Q & A

What are the three methods to calculate national income?

The three methods to calculate national income are the Income Method, the Expenditure Method, and the Output Method. However, the lesson focuses on the Income and Expenditure Methods.

What formula is used in the Income Method to calculate national income?

The formula used in the Income Method is: Y = R + W + I + P, where R is Rent, W is Wages, I is Interest, and P is Profit.

What are some key data types that are not relevant for the Income Method calculation?

Data that are not relevant for the Income Method are referred to as 'data pengganggu,' which include items like the population data or any other data not directly related to Rent, Wages, Interest, or Profit.

How does the Expenditure Method differ from the Income Method in calculating national income?

The Expenditure Method uses the formula Y = C + I + G + X - M, where C is Consumption, I is Investment, G is Government Expenditure, X is Exports, and M is Imports. This method focuses on total spending in the economy, while the Income Method focuses on income from various factors of production.

What is the formula for calculating Per Capita Income?

The formula for calculating Per Capita Income is: Per Capita Income = National Income / Population.

In the first example, using the Income Method, what is the total national income for Country ABC?

Using the Income Method, the total national income for Country ABC is 3,000,000, calculated by adding Rent (600,000), Wages (700,000), Interest (800,000), and Profit (900,000).

In the second example, using the Expenditure Method, what is the national income for Country ABC?

Using the Expenditure Method, the national income for Country ABC is 1,300,000, calculated by adding Consumption (500,000), Investment (400,000), Government Expenditure (300,000), and Exports (200,000), then subtracting Imports (100,000).

How is the Per Capita Income for Country ABC calculated in the second example?

The Per Capita Income for Country ABC is calculated by dividing the national income (1,300,000) by the population (1,000), which results in a Per Capita Income of 1,300.

What are the key components included in the Expenditure Method formula?

The key components included in the Expenditure Method formula are Consumption (C), Investment (I), Government Expenditure (G), Exports (X), and Imports (M).

Why is it important to identify the correct method when calculating national income?

It is important to identify the correct method because each method uses different formulas and components. Using the wrong method can lead to incorrect calculations, which is why understanding the context and data is essential for accurate results.
