Markets and Competition; Determinants of Individual Demand/Supply
What are Markets?
A market is a place where buyers and sellers come together to exchange goods and services. This allows prices to fluctuate based on supply and demand.
What is Competition?
Competition is a market structure in which many sellers compete with each other. This means each seller has a small market share but can influence prices through their behavior.
Determinants of Individual Demand/Supply
Price: Price is the amount of a good or service that sellers are willing to accept for a given quantity. Changes in price directly affect the demand.
Consumer preferences: Consumer preferences determine what goods and services they want and are willing to purchase. Changes in consumer preferences affect demand.
Income: When consumers have more money, they are more likely to buy goods and services. Changes in income affect demand.
Taste and preferences: These are innate characteristics of the good or service that influence consumer demand.
Availability: The amount of a good or service that producers are willing and able to supply is also a determinant of price. Changes in availability affect supply.
How Markets Work
A market works by observing supply and demand. If the quantity of a good or service that producers are willing to supply is greater than the quantity that consumers are willing to purchase, the price will decrease. If the quantity of a good or service that producers are willing to supply is less than the quantity that consumers are willing to purchase, the price will increase.
How Markets and Welfare Are Related
Markets can sometimes lead to negative externalities, which are situations where the actions of one party lead to a decrease in welfare for other parties. Negative externalities arise when a large number of sellers have little market power, allowing them to set prices that are too high.
Examples
Product differentiation: Companies that produce unique products can set high prices because they have little competition.
Perfect competition: This is a market structure in which there are many buyers and sellers who are price takers, leading to prices that are equal to marginal cost.
Monopoly: A monopoly is a market structure in which there is only one seller. Monopolies have market power and can set prices that are higher than would be set in a competitive market
