Examples of Factors that Shift the LRAS Curve: Technology, Capital & Labor

📚 Quick Study Guide

• 🌍 The Long-Run Aggregate Supply (LRAS) curve represents the potential output of an economy when all resources are fully employed.
• ⚙️ Shifts in the LRAS curve indicate changes in the economy's productive capacity.
• 💻 Technology: Advancements in technology increase productivity, allowing more output with the same amount of resources. This shifts the LRAS curve to the right.
• 🧱 Capital: An increase in the stock of capital (e.g., machinery, infrastructure) enhances the economy's ability to produce goods and services, also shifting the LRAS curve to the right.
• 👷 Labor: An increase in the size or skill level of the labor force expands the economy's productive capacity, shifting the LRAS curve to the right.
• 📈 The LRAS curve is vertical, indicating that output is determined by factors of production, not by the price level.
• 💡 Anything that increases the efficiency or availability of factors of production will shift the LRAS.
