APPMaster produced and test marketed a digital product that is particularly appealing to millennials. The variable cost per unit is $5.40. Test markets research predicts that global monthly sales will be 17,000 downloads (sales) at $10 and 9,160 at $14. The elasticity of demand was found to be constant( i.e. curvilinear rather than linear). Suppose APP Master launches a new promotional campaign that reduces target customers sensitivity to price and the elasticity of demand falls by 20% from what you calculated above.
What then will be a. new price elasticity of demand? b. optimal gross margin? c. optimal selling price?
According to the mid-point formula, the price elasticity of demand for a product is given by:
PED = (Q2 – Q1) / [(Q2 + Q1)/2] / (P2 – P1) / [(P2 + P1)/2]
PED is found to be -1.8 as computed below
Q1 | Q2 | P1 | P2 | Q2-Q1 | (Q2+Q1)/2 | %Q | P2-P1 | (P1+P2)/2 | %P | Ed |
17000.00 | 9160.00 | 10.00 | 14.00 | -7840.00 | 13080.00 | -59.94 | 4.00 | 12.00 | 33.33 | -1.8 |
Now the new campaign reduces target customers sensitivity to price and the elasticity of demand falls by 20%.
Hence new elasticity is -1.44
Optimal selling price P = MC x (PED/PED + 1) = 5.40*(-1.44/-1.44 + 1) = $17.67
Optimal gross margin = (P - MC)/MC = (17.67 - 5.40)/5.40 = 2.72
