Study Notes
Market Forces of Supply and Demand
- Supply and demand are crucial for the functioning of market economies, influencing pricing and resource allocation.
- Prices are determined by the interaction of supply and demand, influencing how scarce resources are distributed.
Assumptions of the Competitive Market Model
- A competitive market contains many buyers and sellers, ensuring individual actions do not affect market prices (price takers).
- Effective outcomes arise under specific conditions:
- Multiple buyers and sellers exist in the market.
- Perfect information is available to all participants.
- Freedom of entry and exit for firms.
- Goods offered are identical.
- Participants act out of self-interest.
- Clearly defined property rights protect ownership.
Characteristics of Competitive Markets
- In perfectly competitive markets, all products sold are homogeneous.
- No single buyer or seller can influence the market price, maintaining fair competition.
Market Structures Spectrum
- Four primary market structures based on production concentration and market power:
- Perfectly Competitive Market
- Monopolistic Competition
- Oligopoly
- Monopoly
Demand
- Quantity demanded reflects how much of a good consumers are willing to buy at different prices.
- The Law of Demand states that as the price of a good rises, the quantity demanded typically falls, all else being equal.
- A demand schedule is a tabulated representation linking prices to quantities demanded, illustrating consumer behavior.
Demand Curve
- The demand curve visually represents the relationship between the price of a good and the quantity demanded, enabling better understanding of consumer choices.
- Example: Rachel’s demand for milk shows decreased quantity demanded as price per litre increases from €0.00 to €1.00, illustrating the Law of Demand.
