Review Questions
Explain how interest is accounted for in the calculation of Gross Domestic Product (GDP).
Interest income earned by lenders and interest expenses incurred by borrowers are both included in the calculation of GDP.

The inclusion of interest-related income and expenses ensures that the GDP measure accurately reflects the size and activity of the overall economy.
Describe the relationship between interest rates and economic activity.
Changes in interest rates can have a significant impact on the level of economic activity. Higher interest rates make borrowing more expensive, which may discourage consumer spending and business investment. Conversely, lower interest rates can stimulate economic growth by making it cheaper for individuals and businesses to borrow money and invest in new projects. The interest rate is a key tool used by central banks to influence the overall level of economic activity and achieve desired policy objectives, such as maintaining stable prices and promoting full employment.
Analyze the importance of accurately measuring interest-related income and expenses in the calculation of Gross Domestic Product (GDP).
The accurate measurement of interest-related income and expenses is crucial for the calculation of Gross Domestic Product (GDP), as it reflects the financial transactions that occur between lenders, borrowers, and the government. Interest payments represent a significant component of national income and expenditure, and their inclusion in the GDP calculation ensures that the measure accurately captures the size and activity of the overall economy.
