Question on market size

Question

The potential market size for this case is determined by calculating the revenue per flight based on the price elasticity diagram. It's said that because the potential per flight is the highest at $15, the market size is $15 * 99m (potential users) * 20% (users that will buy at $15) = $297m. However, if we price it at $15 shouldn't we be able to grab the willigness to pay of those that would pay more than $15? Meaning our potential market size would be 99m (potential users) * (20% (WtP = $15) + 10% (WtP = $20) + 5% (WtP = $25)) * $15 = $520m.

Did I misunderstood something or is there a mistake in the solution?

Answer 1

Hello,

Everytime that you see an exhibit like this, you have to consider only the percentage related to you price. In other words, it's like people that would pay more than 15$ are already included in your 20%.
Does it make sense?

Answer 2

Hello!

I think it´s a fair point to be adressed with the interviewer, since indeed we might capture some clients with higher willigness to pay. However, taking it for granted and including them is too much, since you cannot be sure either.

Think, for instance, making an extreme case, that then Zara could "asume" that they can absorbe all the market from higher-price brands, when in reality they don´t, since the value proposition of the higher-priced segment is other.
