APM 3.3 & 3.4 Readings

What does Short-Run Aggregate Supply (SRAS) represent in an economy?

• Total production of goods and services at different price levels when wages and input costs are sticky

• Total production of goods and services at constant price levels

• Total production of goods and services when wages and input costs are flexible

• Total production of goods and services in the long run

Which of the following is a reason for a rightward shift in the SRAS curve?

• Lower input costs

• Higher input costs

• Stricter regulations

• Natural disasters

What is the effect of expansionary fiscal policy on SRAS?

• Increases SRAS

• Decreases SRAS

• No effect on SRAS

• Causes SRAS to become vertical

What causes cost-push inflation according to the passage?

• Rising production costs

• Excessive aggregate demand

• Decreasing production costs

• Stable production costs

How do higher prices affect producers in the short run according to the SRAS concept?

• Incentivize producers to increase output

• Discourage producers from increasing output

• Have no effect on producers

• Cause producers to decrease output

What is stagflation as described in the passage?

• A period of stagnant economic growth combined with inflation

• A period of high economic growth and low inflation

• A period of deflation and high economic growth

• A period of stable prices and high economic growth

Which of the following is NOT a factor that can cause a leftward shift in the SRAS curve?

• Higher worker productivity

• Higher input costs

• Natural disasters

• Stricter regulations

Supply Chain Disruptions and SRAS:

Global supply chain disruptions, caused by the COVID-19 pandemic and geopolitical tensions, have increased production costs and reduced the availability of goods. This has led to leftward shifts in SRAS, contributing to higher prices and slower economic growth.

Reflective Question: How do supply chain disruptions affect short-run aggregate supply, and what policies can mitigate their impact?

Rising Energy Costs and Inflation:

Energy price spikes, such as those caused by conflicts in oil-producing regions, increase transportation and production costs for businesses. As a result, firms reduce output, shifting SRAS left and driving inflation higher.

Reflective Question: How do rising energy costs contribute to cost-push inflation, and what role do government policies play in stabilizing prices?

Technology and Productivity Growth:

Advances in automation, artificial intelligence, and renewable energy have the potential to shift SRAS right by increasing efficiency and lowering production costs. While this boosts economic output, it may also disrupt traditional labor markets.

Reflective Question: How does technological progress influence SRAS, and what policies can ensure that economic benefits are widely shared?
