Regulation
A law that must be followed. Violation of the regulation may result in punishment.
Law of Demand
The negative relationship between price and quantity demanded. When price rises, quantity demanded, falls and vice versa.

Market
Where buyers and sellers come together. Where demand and supply occurs to determine a price.
Exceptions to the law of demand
Snob goods, Giffen goods, a good where the demand is affected by expectations and addictive goods
Exceptions to the law of supply
Fixed supply, and when the suppliers are close to maximum capacity
Individual demand
Quantity demanded by individual consumers at different prices
market demand
Aggregate quantity of a good/service demanded by all consumers at different prices
Derived demand
Demand for a good for its use in production of other goods
Composite demand
Increase in demand for one good causes a decrease in another
Joint demand
Goods bought and sold together (complementary)
Effective demand
Willingness of consumers to purchase goods/services at different prices
Demand schedule
Table showing quantity demanded a different prices
Movement along the demand curve
Change in price is only factor that causes movement along the demand curve
Factors that cause a shift in the demand curve
Change in income
Price substitutes
Price of compliments
Advertising and changes in taste.
Expectations of future price.
Population
Willingness of financial institutions to lend.
Unplanned factors, example: Covid.
How does more demand effect the demand curve?
More demand shifts demand curve to the right
How does less demand effect the demand curve?
Less demand, the curve shifts to the left
Specialisation of labour
When workers are assigned a specific task
Advantages of specialisation of labour
Workers who specialise in one task may become more efficient(might make unit price lower) Workers are more productive as they get better/faster at their assigned task. Training costs are lower.
Disadvantages of specialisation of labour
For a worker specialising might become repetitive and boring For the individual worker, there is little chance of career progression As the worker has a narrow range of skills, alternative work will be difficult to find.

Quantity of supply of an individual
Market supply
Aggregate quantity of goods supplied by all suppliers in the market
Supply schedule
Table that gives quantity of a good/service that would be supplied by suppliers at different prices
Movement along the supply curve

shift of a supply curve
Change in cost of production
Price of related goods/services.
Unplanned factors, example: natural disasters
Government/EU subsidies (payment to suppliers that covers some of the suppliers costs)
Number of sellers
Advances in technology.
Cost benefit analysis
Costs and benefits must be weighed up to make the best decision
Examples of cost
Financial costs, external costs, future projected costs
Examples of benefits
External benefits, future projected benefits, financial benefits
External costs
Loss of wildlife habitats, noise and air pollution, destruction of the landscape
External benefits
Reduce traffic congestion, future investment potential, benefit to local people and businesses.
Market equilibrium and the price mechanism
When graphing, equilibrium is where the demand and supply curves intersect.
Equilibrium price
Price where there is no unsold stock(excess supply) or unsatisfied customers (excess demand)
