Circle the appropriate word or phrase in each of the italicized groups. Recently the price of good A doubled. This resulted in the quantity of good B sold having a minimal (+5%) increase and the price of good B going up substantially (+50%). This suggests that goods A and B are [[ complimentary goods / substitute goods / luxury goods]]. And that, prior to the increase in good A’s price, production of good B was [[below capacity / at or above capacity ]]. It also suggests that, at its current range, the price elasticity of supply for good B is [[ zero / between zero and one / one / greater than one.]]
As we can see that price of good A got doubled. This resulted in the quantity of good B sold having a minimal of 5% increase and the price of good B going up substantially by 50%.
This suggests that goods A and B are substitute goods.
Let's understand what are substitute goods?
Substitute Goods: These are the goods that can be alternatively used for the same purpose.
So as we can see above that increase in price of good A resulted in increase in quantity sold and price of good B, they are substitute goods.
It can be further understood by following graph:
We can say that before increase in the price of good A, production of good B was at or above capacity as they instantly were able to supply 5% more of previous supply.
It also suggests that at its current range, the price elasticity of supply for good B is inelastic i.e., between zero and one.
We can calculate price elasticity of supply by following formula:
Price elasticity of supply = Change in Quantity Supplied/ Change in Price
= 5/50
= 0.1
Thus, price elasticity of supply for good B is inelastic. It can also further understood by the graph given above as increase in price by 50% is resulting in only 5% increase in quantity sold.
