What Happens When the Market Supply Curve Is Vertical?

A vertical market supply curve is illustrated by a line running up and down on the graph. When a market supply curve is vertical, it represents that the quantity of that good is fixed no matter what the price of the good is. A vertical curve illustrates a good that has zero elasticity. The good is always there, but no matter how much a person is willing to pay, extra amounts of that good cannot be created. Land is an example of a good with a vertical supply curve.
