Answer 11

Measures extent to which the demand for a good changes in response to a change in the price of that good
PED=Percentage change in quantity demanded divided by percentage change in price

Question 14

Market supply

Answer 14

Quantity of good/service that all firms plan to sell at given prices in a given period of time

Question 15

Profit

Answer 15

TR=Price X quantity sold

Question 17

Conditions of supply

Answer 17

Question 18

Price elasticity of supply

Answer 18

Measures extent to which the supply of a good changes in response to a change in the price of that good

Question 19

Equilibrium

Answer 19

A state of rest or balance between opposing forces

Question 20

Disequilibrium

Answer 20

A situation in a market when there’s excess supply or excess demand

Question 21

Market equilibrium

Answer 21

When planned demand =planned supply and the demand curve crosses the supply curve. No excess demand or excess supply in the market.

Question 22

Market disequilibrium

Answer 22

Exists at any price other than the equilibrium price. Either excess demand or excess supply exists in the market. Excess demand causes price to rise until a new equilibrium is established. Excess supply causes market price to fall until equilibrium is achieved.

Question 23

Excess supply

Answer 23

When firms wish to sell more than consumers wish to buy, with the price above the equilibrium price

Question 24

Excess demand

Answer 24

When consumers wish to buy more than firms wish to sell, with the price below the equilibrium price

Question 25

Joint supply

Answer 25

When one good is produced, another good is also produced from the same raw materials

Question 26

Competing supply

Answer 26

When raw materials are used to produce one good they can't be used to produce another good

Question 27

Complementary good

Answer 27

A good in joint demand, or a good which is demanded at the same time as the other good

Question 28

Substitute good

Answer 28

A good in competing demand, namely a good that can be used in place of the other good

Question 29

Composite demand

Answer 29

Answer 30

Question 31

Merit good
