Real-World Examples of AD-AS Model Applications and Shocks

📚 Quick Study Guide

• 📈 The Aggregate Demand (AD) curve slopes downward, showing an inverse relationship between the price level and real GDP.
• 📉 The Short-Run Aggregate Supply (SRAS) curve slopes upward, indicating a direct relationship between the price level and real GDP in the short run.
• 📊 The Long-Run Aggregate Supply (LRAS) curve is vertical, representing the potential output of the economy at full employment.
• 💥 Demand-side shocks shift the AD curve (e.g., changes in consumer spending, investment, government spending, or net exports).
• ⚡ Supply-side shocks shift the SRAS curve (e.g., changes in input costs, technology, or labor productivity).
• ⚖️ Macroeconomic equilibrium occurs where AD, SRAS, and LRAS intersect, determining the price level and real GDP.
• 💡 Stabilization policies (fiscal and monetary) aim to counteract AD and SRAS shocks to stabilize the economy.
