Chapter 10: Problem 7

How would a dramatic increase in the value of the stock market shift the AD curve? What effect would the shift have on the equilibrium level of GDP and the price level?

Short Answer

Expert verified

A dramatic increase in the stock market value leads to a rightward shift in the Aggregate Demand (AD) curve due to increased consumer confidence and spending. This shift results in a higher equilibrium level of GDP as producers increase their output to meet the higher demand. Additionally, the overall price level may rise due to increased costs passed on to consumers. Thus, an increase in the stock market value can lead to both higher GDP and increased price levels.

Step by step solution

Understand the Aggregate Demand (AD) curve

The AD curve represents the total demand for goods and services in an economy at various price levels. It illustrates the relationship between the overall price level and the quantity of goods and services demanded. The curve slopes downward, indicating that as the price level falls, the quantity of goods and services demanded increases, and vice versa.

Examine the effect of the stock market on the AD curve

A dramatic increase in the stock market value increases the wealth of investors. This rise in wealth tends to increase consumer confidence and spending. As people feel wealthier and more confident about their financial prospects, they are more likely to spend money on goods and services. This increase in consumer spending leads to an increase in the overall demand for goods and services in the economy, which causes the AD curve to shift to the right.

Analyze the effect of a rightward shift in the AD curve on GDP

A rightward shift in the AD curve, caused by the increase in consumer spending, leads to a higher equilibrium level of GDP. This is because when there is an increase in demand for goods and services in the economy, producers respond by increasing their output to meet this higher demand. This increase in output, measured as GDP, leads to higher economic growth.

Analyze the effect of a rightward shift in the AD curve on the price level

As the demand for goods and services increases due to the shift in the AD curve, producers may face capacity constraints and increasing marginal costs. This can lead to higher prices for goods and services in the economy, as producers may pass these increased costs onto consumers. As a result, the overall price level may rise in response to the rightward shift in the AD curve. In conclusion, a dramatic increase in the stock market value tends to shift the AD curve to the right, leading to a higher equilibrium level of GDP and an increase in the price level.
