Study Notes
Surplus and Equilibrium
- A surplus occurs when the current price exceeds the equilibrium price, leading to excess supply.
- Surpluses result in a decrease in prices as producers seek to sell surplus stock.
- A rightward shift in the supply curve indicates an excess quantity supplied at previous equilibrium.
Shortages
- A shortage happens when quantity demanded surpasses quantity supplied at the current market price, causing prices to rise.
- Buyers compete with each other to secure limited goods during shortages.
Market Clearing
- "Market clearing" describes a situation where quantity demanded equals quantity supplied, eliminating surpluses and shortages.
- The equilibrium price is critical as it clears the market, balancing supply and demand without excess.
Impact of Changes in Supply and Demand
- A decrease in consumer income increases the equilibrium price and quantity for inferior goods, like used cars.
- Decreased demand results in lower equilibrium prices and quantities, as seen with changes in fashion trends.
- An increase in supply, stimulated by improved production methods (e.g., hormones for cows), leads to lower prices but higher quantities.
Cross-Price Effects
- A decrease in the price of one good (e.g., potato chips) can lead to a decline in both equilibrium price and quantity for its substitutes (e.g., pretzels).
- Changes in demand and supply balance dictate overall market movements: demand increases coupled with supply decreases will raise equilibrium prices.
Price Adjustments
- The equilibrium price can be influenced by various factors; if demand increases faster than supply, prices will rise; if supply increases faster than demand, prices will fall.
- Market dynamics are responsive; both equilibrium price and quantity can alter based on shifts in either demand or supply.
Conclusion
- Understanding how surpluses and shortages interact with market prices is essential to grasping economic principles.
- The correlation between supply shifts, demand changes, and resultant price movements is foundational in economic theory.
