Q

What is a substitute good or service?

A

goods and services that are similar. For example, if the price of one chocolate rose then the demand for another brand, that has not risen in price will increase.

16
Q

Why does the income effect occur?

A

because as the price of a good rises, it means the consumers income buys them less units of any product. This means that their purchasing power, the amount that their money buys them, has fallen. This again explains why as price rises, quantity demanded falls.

17
Q

If the price of a good decreases then people will buy more, this is shown by a movement along the demand curve. What is this referred to by?

A

an extension in demand
PRICE NEVER CAUSES A SHIFT, ONLY A MOVEMENT

18
Q

If the price of a good increases then people will buy less, this is shown by a movement along the demand curve. What is this referred to by?

A

a contraction in demand
PRICE NEVER CAUSES A SHIFT, ONLY A MOVEMENT

19
Q

What are some factors that shift the demand curve?(9)

A

Population, Advertising, The price of subsitute goods and services, incomes, fashion and trends, interest rates, the price of complementary goods and services, the weather, expectations

20
Q

What is supply?

A

The amount of goods or services that producers are willing and able to sell at a given price. THIS IS NOT OUTPUT

21
Q

Be able to draw supply curves from supply schedules

A

Look at jotter and notes.

22
Q

Describe the relationship between supply and price.

A

A positive correlation between supply and price exists.

23
Q

Why does the supply curve slope upwards?

A

-The profit motive, when the market price rises following an increase in their output.
-New entrants coming into the market, higher prices may create an incentive for other businesses to enter the market leading to an increase in total supply.
-Production and costs, when output expands, a firms production costs tend to rise, therefore a higher price is needed to cover these extra costs of production.

24
Q

What does it cause if the supply curve shifts outwards?

A

it causes an increase in supply at all prices

25
Q

What does it cause if the supply curve shifts inwards?

A

it causes a decrease in supply at all prices

26
Q

What is productivity?

A

the amount produced per unit input in a period of time.

27
Q

What are some determinants of supply?

A

Costs of production, changes in production technology, tax, subsidy, weather/climate conditions.

28
Q

Be able to draw supply diagrams to explain how changes in the determinants of supply affect price and quantity supplied

A

Look at notes and jotter.

29
Q

What is a market?

A

a market is where buyers and sellers of a good or service come together to exchange their good or service for an agreed price.

30
Q

What are some different types of market?

A

technology, food, clothes, jewellery etc etc

31
Q

Be able to draw a demand and supply diagram to describe how equilibrium price and quantity are set

A

Look at notes and jotter.

32
Q

Be able draw a demand and supply diagram to describe how shortage and surplus situations (excess demand and excess supply) are returned to equilibrium, ie market clearing

A

Look at notes and jotter.

33
Q

Be able to draw a demand and supply diagram to describe how changes in the determinants of demand and/or supply affect equilibrium price and quantity

A

Look at notes and jotter.
