Which of these products or services is likely to have an inelastic supply on a short run?

A. Cargo Ships

B. Haircuts

C. Staples

Inelastic supply is an economic situation in which the price fluctuation of a good or service does not lead to a proportional increase or decrease in the supply of the same product or service. In other words, the production does not increase nor decrease a lot if the price of the good or service rise or fall.

Therefore the correct answer is letter A. Cargo Ships, taking into account the definition of inelastic supply, let's imagine that there is an increment in the demand of Cargo Ships, it is very difficult to increase the supply in the short run since these goods take a long time, probably months, to be produced. On the other hand, haircuts and staples can increment their production in the short run with greater facility.
