Macroeconomics AD AS Equilibrium
33 flashcards covering Macroeconomics AD AS Equilibrium for the MACROECONOMICS Macroeconomics Topics section.
Macroeconomics AD-AS equilibrium refers to the interaction between aggregate demand (AD) and aggregate supply (AS) in an economy, determining the overall price level and output. This concept is defined by the curriculum outlined in the Principles of Macroeconomics courses, which emphasize understanding how shifts in demand and supply can affect economic equilibrium.
On practice exams, questions often focus on graphical representations of AD-AS models, requiring candidates to analyze shifts due to various economic factors such as fiscal policy, consumer confidence, or external shocks. A common pitfall is misinterpreting the effects of these shifts; for example, candidates might confuse short-run and long-run adjustments, leading to incorrect conclusions about inflation and unemployment.
One practical tip is to always consider the time frame of the economic changes being discussed, as this can significantly alter the implications of your analysis.

- 01
What is aggregate demand?
Aggregate demand is the total demand for all goods and services in an economy at a given overall price level and in a given time period. It is represented by the formula AD = C + I + G + (X - M), where C is consumption, I is investment, G is government spending, X is exports, and M is imports. (Mankiw, Principles of Economics)
- 02
What shifts the aggregate demand curve to the right?
An increase in consumer confidence, government spending, or investment can shift the aggregate demand curve to the right, indicating an increase in overall demand at every price level. (Krugman, Principles of Economics)
- 03
What is aggregate supply?
Aggregate supply is the total supply of goods and services that firms in an economy plan to sell during a specific time period at a given price level. It reflects the production capacity of the economy. (Mankiw, Principles of Economics)
- 04
What factors can lead to a leftward shift in the aggregate supply curve?
Factors such as increased production costs, natural disasters, or reduced availability of resources can lead to a leftward shift in the aggregate supply curve, indicating a decrease in total output at every price level. (Krugman, Principles of Economics)
- 05
When does equilibrium occur in the AD-AS model?
Equilibrium occurs in the AD-AS model when the aggregate demand curve intersects the aggregate supply curve, determining the overall price level and output in the economy. (Mankiw, Principles of Economics)
- 06
What happens to equilibrium price and output during a demand shock?
During a positive demand shock, both equilibrium price and output increase, while a negative demand shock leads to a decrease in both equilibrium price and output. (Krugman, Principles of Economics)
- 07
What is the long-run aggregate supply curve?
The long-run aggregate supply curve is vertical, indicating that in the long run, the economy's output is determined by factors such as technology and resources, not by the price level. (Mankiw, Principles of Economics)
- 08
How does fiscal policy affect aggregate demand?
Fiscal policy, through government spending and taxation, can influence aggregate demand by increasing or decreasing disposable income and consumption, thus shifting the AD curve. (Krugman, Principles of Economics)
- 09
What role does monetary policy play in aggregate demand?
Monetary policy affects aggregate demand primarily through interest rates; lowering interest rates encourages borrowing and spending, shifting the AD curve to the right. (Mankiw, Principles of Economics)
- 10
What is the short-run aggregate supply curve?
The short-run aggregate supply curve is upward sloping, indicating that as prices increase, firms are willing to produce more goods and services due to higher profit margins. (Krugman, Principles of Economics)
- 11
What is stagflation?
Stagflation is an economic condition characterized by stagnant economic growth, high unemployment, and high inflation, often resulting from a leftward shift in the aggregate supply curve. (Mankiw, Principles of Economics)
- 12
What causes an increase in aggregate supply?
An increase in aggregate supply can be caused by improvements in technology, decreases in production costs, or an increase in the labor force, leading to a rightward shift in the AS curve. (Krugman, Principles of Economics)
- 13
What is the impact of a supply shock on the AD-AS model?
A supply shock, such as a sudden increase in oil prices, can shift the short-run aggregate supply curve leftward, leading to higher prices and lower output in the economy. (Mankiw, Principles of Economics)
- 14
How does consumer confidence affect aggregate demand?
Higher consumer confidence typically leads to increased consumer spending, which shifts the aggregate demand curve to the right, indicating higher demand at every price level. (Krugman, Principles of Economics)
- 15
What is the difference between nominal GDP and real GDP?
Nominal GDP measures a country's economic output without adjusting for inflation, while real GDP adjusts for inflation, providing a more accurate reflection of an economy's size and growth. (Mankiw, Principles of Economics)
- 16
What is the role of expectations in the AD-AS model?
Expectations about future economic conditions can influence both aggregate demand and aggregate supply; for example, optimistic expectations can lead to increased investment and consumption. (Krugman, Principles of Economics)
- 17
What is the Phillips Curve?
The Phillips Curve illustrates the inverse relationship between inflation and unemployment, suggesting that lower unemployment can lead to higher inflation and vice versa in the short run. (Mankiw, Principles of Economics)
- 18
How does a decrease in taxes affect aggregate demand?
A decrease in taxes increases disposable income for consumers and businesses, typically leading to an increase in consumption and investment, which shifts the aggregate demand curve to the right. (Krugman, Principles of Economics)
- 19
What is the significance of the intersection of AD and AS curves?
The intersection of the aggregate demand and aggregate supply curves determines the equilibrium price level and output in the economy, indicating where supply meets demand. (Mankiw, Principles of Economics)
- 20
What happens to the AD curve during a recession?
During a recession, the aggregate demand curve typically shifts to the left, indicating a decrease in overall demand for goods and services at every price level. (Krugman, Principles of Economics)
- 21
What is the effect of increased government spending on the AD-AS model?
Increased government spending shifts the aggregate demand curve to the right, leading to higher equilibrium output and price levels in the economy. (Mankiw, Principles of Economics)
- 22
What is the long-run impact of sustained inflation on the AD-AS model?
Sustained inflation can lead to a rightward shift in the long-run aggregate supply curve as businesses adjust to higher price levels, potentially stabilizing output over time. (Krugman, Principles of Economics)
- 23
How does a rise in interest rates affect aggregate demand?
A rise in interest rates typically decreases borrowing and spending by consumers and businesses, leading to a leftward shift in the aggregate demand curve. (Mankiw, Principles of Economics)
- 24
What is the relationship between unemployment and output in the AD-AS model?
In the AD-AS model, higher output is generally associated with lower unemployment, as firms need more workers to produce increased quantities of goods and services. (Krugman, Principles of Economics)
- 25
How do changes in foreign exchange rates impact aggregate demand?
Changes in foreign exchange rates can impact aggregate demand by affecting export and import prices; a weaker currency makes exports cheaper and imports more expensive, shifting the AD curve to the right. (Mankiw, Principles of Economics)
- 26
What is the effect of a tax increase on aggregate demand?
A tax increase typically reduces disposable income, leading to decreased consumption and investment, which shifts the aggregate demand curve to the left. (Krugman, Principles of Economics)
- 27
What is the concept of potential GDP?
Potential GDP is the maximum level of output an economy can sustain over the long term without increasing inflation, determined by factors such as technology and labor force. (Mankiw, Principles of Economics)
- 28
What is the impact of technological advancements on aggregate supply?
Technological advancements can shift the aggregate supply curve to the right by increasing productivity and reducing production costs, leading to higher output at every price level. (Krugman, Principles of Economics)
- 29
What is the significance of the short-run aggregate supply curve?
The short-run aggregate supply curve is significant because it reflects how prices and output adjust in response to demand changes before long-term adjustments occur. (Mankiw, Principles of Economics)
- 30
How does inflation expectations affect wage negotiations?
If inflation expectations rise, workers may demand higher wages to maintain their purchasing power, potentially shifting the short-run aggregate supply curve leftward. (Krugman, Principles of Economics)
- 31
What is the impact of a decrease in oil prices on the AD-AS model?
A decrease in oil prices can shift the short-run aggregate supply curve to the right, leading to lower production costs, increased output, and reduced inflationary pressures. (Mankiw, Principles of Economics)
- 32
What factors can cause the aggregate demand curve to shift?
Factors such as changes in consumer confidence, fiscal policy, monetary policy, and foreign demand can cause the aggregate demand curve to shift either to the left or right. (Krugman, Principles of Economics)
- 33
What is the effect of a positive supply shock on the economy?
A positive supply shock, such as a technological breakthrough, can shift the short-run aggregate supply curve to the right, leading to lower prices and higher output. (Mankiw, Principles of Economics)
