1.3: Introducing the market - the price mechanism Flashcards
Market
Any medium in which buyers and sellers interact and agree to trade at a price.
Buyers
All those people or organisations that want to purchase something; they create the demand for goods and services.
Sellers
All those people or organisations that want to sell something; they create the supply of goods and services.
Demand
The quantity of a good or service that people are willing and able to buy at a given price, at a given time.
Market demand
The sum of all individual demands for a particular good or service.
Demand curve
Shows the relationship between price and quantity demanded on a diagram.
Substitutes
Goods that can be consumed in place of another.
If the price of a substitute increases, the demand curve for the original good shifts to the right.
Complements
Goods that are normally consumed together.
If the price of a complement increases, the demand curve for the original good shifts to the left.
Changes in real incomes
When real incomes changes, so does the quantity demanded.
Normal goods
For most goods and services, as real income rises so too does the quantity demanded and as income drops, so does quantity.
Inferior goods
As income increases, quantity demanded falls and as income falls demand increases.
Changes in tastes and fashion
If the preference for a particular good increases, the demand curve for that good shifts to the right, if it decreases it shifts to the left.
Changes in size and age distribution of the population
As popular increases or decreases so does the demand for most goods and services.
Advertising and branding
The whole point of advertising is to make us all buy more of something i.e. to increase demand and shift the demand curve to the right.
Supply
The amount of a good and service that producers are willing and able to provide, at a given price, at a given time.
Market supply
The total output of all individual suppliers of a particular good or service.
Supply curve
Shows the relationship between price and quantity supplied.
Changes in the costs of production
An increase in costs shifts the supply curve upwards and to the left.
If a furniture maker has to pay for more wood, then profits decline. The less attractive profit opportunities may mean that the producers cut output.
