Learners should be able to:
explain what is meant by elasticity explain what is meant by price elasticity of demand (PED)
calculate PED using point elasticity ‘ explain, with the aid of a diagram, the different values of PED explain why price elasticity of demand varies along a straight line
demand curve explain, with the aid of a diagram, the relationship between PED and
a firm’s total revenue 0 evaluate the factors which determine the degree of PED
evaluate the effect of PED on the impact of an indirect tax and of a

calculate YED evaluate the significance of the numerical value and sign of YED
explain the difference in YED of inferior, normal and superior goods explain what is meant by cross elasticity of demand (XED)
. calculate XED evaluate the significance of the numerical value and sign of XED
explain the difference in XED of substitute, complementary and non
related goods explain what is meant by price elasticity of supply (PES)
calculate PES using point elasticity ‘ explain, with the aid of a diagram, the different values of PES
‘ evaluate the factors which determine the degree of price elasticity
of supply ‘ evaluate the usefulness of and significance of PED, YED, XED and PES
to all economic agents.
