1.3 introducing market Flashcards
consumer sovereignty
the principle that consumers, through their purchasing decisions, determine the demand for goods and services
demand
quantity of a good or service consumers are willing and able to buy at a given price
law of demand
inverse relationship between the
price of a good and the demand for a good - as prices fall customers buy more and vice versa
shifts in demand
- population
- advertising
- substitute goods
- income (disposable)
- fashion + trends
- income tax
- complementary goods
producer objectives
when prices are high, suppliers are willing to produce more output
supply
quantity of a good or service business are willing and able to provide at a given price.
shifts in supply
- production costs
- indirect tax
- no of firms
- technology
- subsidies
- weather (external shocks)
equilibrium
when the price and quantity are at a level at
which supply equals demand - market ‘clears’
excess demand
where demand outstrips supply - leads to shortage
excess supply
where supply is greater than demand - leads to surplus
ceteris paribus
all things being equal
perfectly competitive market
- homogenous products (basic generic items)
- large numbers of buyers and sellers
- perfect knowledge of prices
- low barriers to exit and entry in the market
price mechanism
the means by which millions of decisions taken by consumers and businesses interact to determine the allocation of scarce resources
incentive
consumers choices reflect demand so higher prices act as incentive to suppliers to raise output
signalling function
consumers decisions inform suppliers (e.g. more demand from customers signals to suppliers to increase output and raise prices)
