Elasticity of supply

CONTENT

i.          Meaning of Elasticity of supply.

ii.         Formula for calculating Elasticity of supply.

iii.        Graphical illustration of Elasticity of supply.

DEFINITION – Elasticity of supply can be defined as the degree of responsiveness change in quantity supplied as a result of change in price.  Elasticity of supply measures the extent to which the quantity of a commodity supplied by a producer changes as a result of a little change in the price of the commodity

EVALUATION

2.         With the aid of a diagram, explain what is meant by exceptional supply curve.

3.         Explain the following types of supply (a) Joint supply    (b) Competitive supply

THEORY

1.         State the law of supply.

2.         State two circumstances that can lead to existence of abnormal supply curve.

EVALUATION

1.         Given the figures below:

Price of commodity x in 2004  =  N10

Price of commodity  x 2005  =  N14

Quantity of  x Supplied in 2004  =  20kg

Quantity of  x Supplied in 2005 = 24kg

(a)  Calculate  (i) percentage change in quantity supplied (%).  (ii) percentage change in price (%)

(iii)  Co-efficient of price elasticity of supply (ES)

(b)        From your answer in (i) is the supply elastic or inelastic     (ii) How do you know this:
