IB Economics AD AS - Diagrams

Explain the Aggregate Demand (AD) curve and its components.

• The AD curve shows the relationship between price level and unemployment rate

• The Aggregate Demand (AD) curve shows the relationship between the price level and the quantity of real GDP demanded by households, firms, and the government. Its components include consumption, investment, government spending, and net exports.

• Its components include inflation, interest rates, and government debt

• AD curve represents the supply of goods and services in the economy

Describe the factors that can cause a shift in the Aggregate Demand (AD) curve.

• Shifts in the supply curve

• Fluctuations in the stock market

• Changes in the weather and climate

• Changes in consumer confidence, government spending, investment, and net exports.

Explain the Aggregate Supply (AS) curve and its components.

• The AS curve is composed of the short-run aggregate supply (SRAS) curve, the long-run aggregate supply (LRAS) curve, and the intermediate aggregate demand (IRAD) curve.

• The AS curve is composed of three main components: the short-run aggregate supply (SRAS) curve, the long-run aggregate supply (LRAS) curve, and the intermediate aggregate supply (IRAS) curve.

• The AS curve is composed of the short-run aggregate supply (SRAS) curve, the long-run aggregate demand (LRAD) curve, and the intermediate aggregate supply (IRAS) curve.

• The AS curve is composed of the short-run aggregate demand (SRAD) curve, the long-run aggregate demand (LRAD) curve, and the intermediate aggregate demand (IRAD) curve.

Discuss the factors that can cause a shift in the Short-Run Aggregate Supply (SRAS) curve.

• Changes in consumer preferences

• Technological advancements

• Fluctuations in exchange rates

• Changes in input prices, productivity, and government regulations

Differentiate between the Short-Run Aggregate Supply (SRAS) curve and the Long-Run Aggregate Supply (LRAS) curve.

• The SRAS curve shows the long-run relationship between the price level and the quantity of real GDP supplied, while the LRAS curve shows the short-run relationship between the price level and the quantity of real GDP supplied.

• The SRAS curve is vertical, while the LRAS curve is horizontal.

• The SRAS curve is upward sloping, while the LRAS curve is downward sloping.

• The SRAS curve shows the short-run relationship between the price level and the quantity of real GDP supplied, while the LRAS curve shows the long-run relationship between the price level and the quantity of real GDP supplied.

Explain the concept of equilibrium in the AD-AS model.

• Equilibrium in the AD-AS model occurs when aggregate demand intersects aggregate supply.

• Equilibrium in the AD-AS model occurs when aggregate demand is lower than aggregate supply.

• Equilibrium in the AD-AS model occurs when aggregate demand is unrelated to aggregate supply.

• Equilibrium in the AD-AS model occurs when aggregate demand is higher than aggregate supply.

Discuss the effects of a change in aggregate demand on the price level and real GDP.

• Lower price levels and higher real GDP

• Lower price levels and lower real GDP

• Higher price levels and lower real GDP

• Higher price levels and higher real GDP

Explain the concept of stagflation and its implications in the AD-AS model.

• Stagflation is a situation of high inflation and high unemployment, which contradicts the traditional Phillips curve. In the AD-AS model, stagflation occurs when the aggregate supply curve shifts left due to supply-side shocks, leading to higher prices and lower output.

• Stagflation has no implications in the AD-AS model and is only relevant in the Keynesian model.

• Stagflation occurs when the aggregate demand curve shifts right due to demand-side shocks, leading to lower prices and higher output.

• Stagflation is a situation of low inflation and low unemployment, which supports the traditional Phillips curve.

Discuss the role of government policies in influencing the AD and AS curves.

• Government policies have no impact on the AD and AS curves.

• The AD and AS curves are only influenced by consumer behavior, not government policies.

• AD and AS curves are fixed and cannot be influenced by government policies.

• Government policies can shift the AD and AS curves.

Explain the concept of the Phillips curve and its relationship with the AD-AS model.

• The Phillips curve shows a positive correlation between inflation and unemployment. In the AD-AS model, the Phillips curve does not help to explain the short-run trade-off between inflation and unemployment.

• The Phillips curve has no relationship with inflation and unemployment. In the AD-AS model, the Phillips curve is not considered in explaining the short-run trade-off between inflation and unemployment.

• The Phillips curve shows the direct relationship between inflation and unemployment. In the AD-AS model, the Phillips curve has no impact on the short-run trade-off between inflation and unemployment.

• The Phillips curve shows the inverse relationship between inflation and unemployment. In the AD-AS model, the Phillips curve helps to explain the short-run trade-off between inflation and unemployment.
