A - Market System Flashcards
Market
Where buyers and sellers communicate and exchange goods and services for money
Functions of market system
- Price determination
2. Resource allocation
Demand
Amount of good BOUGHT at given prices over period of time
Supply
Amount of good supplied at given prices over period of time
Demand schedule
Amount of good DEMANDED at different prices in a table
Demand curve
Demand schedule plotted on graph
Correlation of price and Qd
Inversely related / negatively correlated
Factors affecting demand (6)
SCAIPT
Substitutes, Complements, Advertising, Income, Population, Tastes and fashion
Types of goods (based on income)
Normal
Inferior
Luxury
Population demographics (4)
Age, gender, geography, ethnicity
Factors affecting supply
SCNPTT
Subsidies, (production) Cost, Natural conditions, Prices of other goods, Technology, (indirect) Taxes
Movement vs shift of curve
Movement - affected by price
Shift - affected by many factors
Equilibrium price
When demand and supply equal
Change in equilibrium price and quantity after change in supply and demand
Supply decreases - E price increases, quantity decreases
Demand decreases - E price decreases, quantity decreases
Total revenue
Amount of money generated from sale of output
Price elasticity of demand
Responsiveness of demand to change in price
Inelastic D - definition, slope, value of elasticity
Change in demand small in proportion to change in price; steep slope; negative with number < 1
Elastic D - definition, slope, value of elasticity
Change in demand large in proportion to change in price; flat slope; negative and number > 1
Factors affecting price elasticity of demand
(SIN)
proportion of Income, degree of Necessity, number of Substitutes
Perfectly (in)elastic
P inelastic - vertical line - demand never changes
P elastic - horizontal line - price elasticity infinite
Price elasticity of supply
Responsiveness of supply to change in price
Inelastic S - definition, slope, value of elasticity
Change in supply small in proportion to change in price; steep upwards slope; positive and less than 1
Factors affecting PES
TIME (SPS)
Stock levels, Production speed, Spare capacity
Value of inelastic vs elastic IED
Inelastic - between 1 and -1
Elastic - >1 or
Normal vs inferior goods for IED
Normal - positive IED
Inferior - negative IED
Factors affecting IED
Necessities vs luxuries
