Chapter 24: Problem 11

What impact would a decrease in the size of the labor force have on GDP and the price level according to the AD/AS model?

Short Answer

Expert verified

A decrease in the size of the labor force can lead to a decrease in GDP and a potential increase in the price level, according to the AD/AS model. This outcome occurs due to simultaneous leftward shifts in the aggregate demand and aggregate supply curves, resulting from a smaller labor force causing a reduction in both the production and consumption of goods and services. The actual impact on GDP and the price level depends on the specific economic conditions and the extent of the labor force reduction.

Step by step solution

Understand the AD/AS model

The AD/AS model is a graphical representation of an economy's aggregate demand (the total demand for all goods and services produced within the nation at various price levels) and aggregate supply (the total supply of all goods and services produced within the nation at various price levels). The intersection of the Aggregate Demand and Aggregate Supply curves determines the equilibrium price level and the economy's output (GDP).

Analyze the impact of a decrease in the labor force on the AD and AS curves

A decrease in the labor force leads to a decrease in the number of workers available to produce goods and services in the economy. This reduction in available workers affects both the aggregate demand and aggregate supply curves. A smaller labor force means that fewer goods and services can be produced at each price level, causing the aggregate supply curve to shift to the left. Additionally, a decrease in the labor force may also cause a decrease in aggregate demand since there will be fewer employed consumers with income to spend on goods and services. This can cause the aggregate demand curve to shift to the left as well.

Determine the new equilibrium point and its impact on GDP and the price level

With both the aggregate demand and aggregate supply curves shifting to the left, the new equilibrium point will be located at a lower output level (GDP) and a potentially higher price level, depending on the magnitudes of the shifts. The decrease in GDP suggests that the economy is producing fewer goods and services overall, which is consistent with a smaller labor force. The higher price level indicates that consumers may be willing to pay more for the limited supply of goods and services available in the market.

Conclusion

According to the AD/AS model, a decrease in the size of the labor force will likely cause a decrease in GDP and an increase in the price level due to simultaneous leftward shifts in the aggregate demand and aggregate supply curves. The actual impact on GDP and the price level will depend on the specific conditions in the economy and the extent of the labor force reduction.
