Lesson Objectives
• To understand and be able to illustrate a market
• To be able to illustrate and explain market equilibrium and how this changes
• To e able to explain disequilibrium and the concept of market forces and the price mechanism

• A market is defined as a place where buyers and sellers meet to exchange goods and services
• Examples of markets?• Markets are illustrated using supply and
demand curves together.

Equilibrium• When a market is in equilibrium it
means it is in a state of balance.• Market equilibrium occurs where supply
equals demand.• When planned supply meets planned
demand we can determine the equilibrium price (known as the ‘market price’) and the equilibrium quantity traded in a market.

• Assuming markets are competitive and consumers and producers follow their self interests (utility and profit maximisers) then scarce resources can be allocated efficiently via the price mechanism

Disequilibrium
• When demand and supply are not equal a state of disequilibrium will occur
• Market forces (the ‘invisible hand’) should move price back to it’s equilibrium

• Excess supply- producers have to lower prices to sell output. This downward pressure on price is sometimes known as a ‘buyers market’
• Excess demand- prices are ‘bid up’- ‘sellers market’The price mechanism ensures that a free market (a market with no government intervention) will always end up in equilibrium

Recall
• What factors cause a shift in demand?
• What factors cause a shift in supply?

Effect of an Increase in Demand
• Time periods–Momentary- supply is fixed– Short-run- the interval which must
elapse before more can be supplied with existing capacity. At least one factor of production will remain fixed
– Long run- the time interval long enough to change all factors of production
–Now illustrate on your handouts

Effect of an increase in supply
• In the short run, ceteris paribus, an increase in supply will lower the price, this in turn will cause an extension in demand
• Illustrate using a diagram
