Correct Option: C. It increases the potential output and can lead to economic growth.
Detailed Explanation:
- Understanding the Working-Age Population:
-
The working-age population typically refers to individuals aged 15 to 64 who are capable of working. An increase in this demographic means more people are available to participate in the labor force.
-
Impact on Labor Supply:
-
When the working-age population increases, the supply of labor in the economy also increases. This means that there are more individuals available to fill jobs, which can lead to a more dynamic labor market.
-
Potential Output:
-
Potential output refers to the maximum amount of goods and services an economy can produce when it is operating at full efficiency. An increase in the working-age population can enhance this potential output because:
- More workers can contribute to production.
- A larger workforce can lead to specialization and division of labor, which increases efficiency.
- More workers can also lead to innovation and entrepreneurship, as new ideas and businesses emerge from a larger pool of talent.
-
Economic Growth:
-
Economic growth is often measured by the increase in a country’s Gross Domestic Product (GDP). With more people working, the economy can produce more goods and services, leading to higher GDP. This growth can also create more jobs, further reducing unemployment in the long run.
-
Long-Term Effects:
- In a growing economy, an increase in the working-age population can lead to a virtuous cycle:
- More jobs → Higher income → Increased consumer spending → More demand for goods and services → Further economic growth.
Why Other Options Are Incorrect:
- Option A: It leads to higher unemployment rates due to an oversupply of labor.
-
While it is true that an increase in the labor supply can lead to higher unemployment in the short term if job creation does not keep pace, this is not a typical outcome in a growing economy. In a healthy economy, the demand for labor often increases alongside supply, mitigating the risk of higher unemployment.
-
Option B: It decreases the overall productivity of the economy.
-
This option is misleading. An increase in the working-age population does not inherently decrease productivity. In fact, it can enhance productivity through increased labor participation and specialization. Productivity may decline if the new workers are not adequately trained or if there are structural issues in the economy, but this is not a direct consequence of an increased working-age population.
-
Option D: It has no significant impact on the labor market dynamics.
- This option is incorrect because an increase in the working-age population significantly impacts labor market dynamics. It changes the supply of labor, influences wage levels, and can affect employment rates and economic growth. Ignoring these dynamics overlooks the fundamental principles of labor economics.
Summary for Revision:
- An increase in the working-age population typically leads to a larger labor supply, enhancing potential output.
- More workers can improve productivity through specialization and innovation.
- Economic growth is likely as increased labor supply can lead to higher GDP and job creation.
- Short-term unemployment may rise if job creation does not match labor supply, but this is not the typical outcome in a growing economy.
