๐Ÿ“š Quick Study Guide

  • ๐ŸŒ SRAS (Short-Run Aggregate Supply): Represents the total quantity of goods and services that firms are willing and able to supply at different price levels in the short run. Shifts are primarily caused by changes in input costs (wages, raw materials, energy prices) and productivity.
  • โš™๏ธ LRAS (Long-Run Aggregate Supply): Represents the potential output of the economy when all resources are fully employed. It is vertical at the full employment level of output. Shifts are caused by changes in the economy's productive capacity (technology, capital stock, natural resources, human capital).
  • ๐Ÿ’ธ SRAS Shifters:
    • ๐Ÿ“ Changes in input prices (e.g., wages, oil prices)
    • ๐ŸŒฑ Changes in productivity
    • ๐Ÿ›ก๏ธ Supply shocks (e.g., natural disasters)
  • ๐Ÿงฑ LRAS Shifters:
    • ๐Ÿงช Changes in technology
    • ๐Ÿข Changes in capital stock
    • โ›๏ธ Changes in natural resources
    • ๐Ÿง  Changes in human capital
  • ๐Ÿ“ˆ Impact of Shifts:
    • โžก๏ธ Rightward shift of SRAS: Increased output, decreased price level (in the short run).
    • โฌ…๏ธ Leftward shift of SRAS: Decreased output, increased price level (in the short run).
    • โžก๏ธ Rightward shift of LRAS: Increased potential output.
  • ๐Ÿงฎ Key Formula: $GDP = C + I + G + (X - M)$ where C = Consumption, I = Investment, G = Government Spending, X = Exports, M = Imports. Changes in these components can influence Aggregate Demand, which interacts with SRAS and LRAS.

Practice Quiz

  1. What primarily causes shifts in the Short-Run Aggregate Supply (SRAS) curve?
    1. Changes in government spending
    2. Changes in consumer confidence
    3. Changes in input costs and productivity
    4. Changes in the money supply
  2. Which of the following would cause a rightward shift in the Long-Run Aggregate Supply (LRAS) curve?
    1. An increase in the price level
    2. A decrease in the money supply
    3. An improvement in technology
    4. An increase in wages
  3. A decrease in oil prices would most likely cause:
    1. A leftward shift in the SRAS curve
    2. A rightward shift in the SRAS curve
    3. A leftward shift in the LRAS curve
    4. A rightward shift in the LRAS curve
  4. What does the LRAS curve represent?
    1. The actual output of the economy
    2. The potential output of the economy at full employment
    3. The aggregate demand in the long run
    4. The short-run supply of goods and services
  5. An increase in the education level of the workforce would most likely shift:
    1. Only the SRAS curve
    2. Only the LRAS curve
    3. Both the SRAS and LRAS curves
    4. Neither the SRAS nor the LRAS curves
  6. If the SRAS curve shifts to the left, what is the likely impact on the economy?
    1. Increased output and decreased price level
    2. Decreased output and increased price level
    3. Increased output and increased price level
    4. Decreased output and decreased price level
  7. Which of the following factors does NOT directly shift the LRAS curve?
    1. Changes in technology
    2. Changes in capital stock
    3. Changes in consumer spending
    4. Changes in natural resources
