Study Notes
Law of Demand
- A reduction in the price of a good typically results in an increase in the quantity demanded, illustrated by a 5% increase in salt purchases following a price drop.
- The law of demand states that when prices rise, demand decreases, exemplified by a 5% drop in salt purchases when the price doubles.
Relative Prices
- Relative prices denote the price of one good expressed in terms of another, impacting consumer choices and demand.
- The increase in the price of a bag of coffee to $20 compared to $14 for tea leads to a decrease in the relative price of tea.
Demand Shifts
- Demand can decrease due to lower incomes or when substitutes become cheaper; e.g., a price drop in wireless service reduces demand for cable Internet.
- A shift in consumer tastes toward cable increases demand for cable Internet despite alternatives.
Complementary and Substitute Goods
- Goods can be classified as substitutes or complements based on their relationship:
- If bacon prices rise and sausage demand increases, they are substitutes.
- An increase in tennis racquet prices leading to a decrease in tennis ball demand implies they are complements.
- Significant demand shifts occur when the prices of related goods change (e.g., chicken's price affecting fish demand).
Law of Supply
- The law of supply illustrates a direct relationship between the price of a good and the quantity supplied; as price increases, so does supply.
- A movement along the supply curve occurs due to price changes, while non-price factors can shift supply leftward or rightward, such as technological improvements or increased production costs.
Market Dynamics
- An outward shift in the supply curve can result from technological advancements or additional firms entering the market, increasing equilibrium quantity and potentially lowering prices.
- A shortage occurs when quantity demanded exceeds quantity supplied, generally when prices are set below equilibrium levels, resulting in upward pressure on prices.
Demand and Supply Interaction
- Equilibrium in the market is achieved when quantity demanded equals quantity supplied, influenced by shifts in demand or supply.
- If both demand and supply increase, equilibrium price may remain constant, while varying shifts lead to different outcomes in price and quantity.
Impact of External Factors
- Factors influencing demand include consumer tastes, income levels, and prices of related goods.
- An increase in input costs for producers (e.g., aluminum for soft drinks) results in a decrease in supply, affecting pricing dynamics in the market.
Key Concepts in Market Behavior
- Inferior goods see demand drop as consumer income rises, highlighting the inverse relationship between income levels and demand for specific goods (e.g., reduced demand for eggs).
- The market clearing price (or equilibrium price) is vital for balancing supply and demand in competitive markets, ensuring efficient allocation of resources.
