Which of the following statements is correct?Which of the following is correct about the business cycle? It shows that economies go through periods of increasing and decreasing nominal GDP. It shows that economies go through periods of increasing and decreasingreal GDP. An expansion is defined as a period of sustained price increases. A recession is defined as a period of decreasing nominal GDP. GDP can be calculated by adding up the values of all final goods produced. GDP can be calculated by adding up the value of all final services produced. GDP can be calculated by adding up the values of all intermediate goods produced. GDP can be calculated by adding up the values of all for of its components.
The Correct Answer and Explanation is:
The correct statement is: “It shows that economies go through periods of increasing and decreasing real GDP.”
Explanation:
The business cycle refers to the natural fluctuation of economic activity over time, which involves periods of expansion (growth) and contraction (recession). These cycles can be measured by real GDP, not nominal GDP. Here’s why the other statements are incorrect:
- Nominal GDP vs. Real GDP:
- Nominal GDP refers to the total market value of all final goods and services produced in a country within a given time period, without adjusting for inflation. This can be misleading when comparing different time periods because inflation can cause GDP to appear higher even if the actual production hasn’t increased.
- Real GDP, however, adjusts for inflation and provides a more accurate reflection of an economy’s growth because it accounts for price level changes. The business cycle tracks changes in real GDP, as it focuses on the actual quantity of goods and services produced, independent of inflation.
- Expansion Definition:
- An expansion refers to a period of economic growth where real GDP increases. It is not specifically defined as a period of sustained price increases, which is more about inflation. Inflation can occur during an expansion, but it isn’t a defining characteristic of it.
- Recession Definition:
- A recession is generally defined as a period of economic decline where real GDP contracts for two consecutive quarters. It does not depend on nominal GDP (which could still rise due to inflation), but rather on the real value of output.
- GDP Calculation:
- GDP can be calculated by adding up the value of final goods and services produced within a country, not intermediate goods. Intermediate goods are used in the production of final goods, so including them would lead to double counting. The correct method is to include only final goods and services to avoid this issue.
So, the most accurate statement is that the business cycle tracks changes in real GDP, reflecting the economy’s expansion and contraction based on the actual volume of production rather than nominal value.
