D. Supply and Demand Flashcards
Supply
(S) the quantity supplied at certain prices; different than quantity
Demand
(D) attitude of those in the market buying
Firm
business or organization (owned by an individual)
Factor Markets
the exchange of inputs we produce
Product markets
the exchange of goods and services
Market power
a condition in which an individual or firm has an unfair advantage (decreases efficiency)
Equal access to information
limits market power
Pareto Optimality
a situation where there is no way to make someone better off without making someone worse off (highest efficiency)
Elasticity
amount that demand responds to market conditions
Inelastic
insignificant change in demand regardless of market conditions
Necessity
a good for which there are no substitutes; more inelastic; e.g healthcare, gasoline
Luxury
more elastic
Factors that determine inelasticity
Necessity vs. luxury
Price and quantity of available substitutes
Time frame
Price relative to wealth and income
Measuring elasticity
ϵ = % of quantity change % of price change ϵ<1 then inelastic ϵ>1 then elastic ϵ=0 then perfectly inelastic ϵ= 1 then unitary elasticity
Unitary elasticity
percentage change in quantity and price are equal
