When the elasticity is less than one, the supply of the good can be described as "inelastic"; when it is greater than one, the supply can be described as "elastic". An elasticity of zero indicates that quantity supplied does not respond to a price change: the good is "fixed" in supply. Such goods often have no labor component or are not produced, limiting the short run prospects of expansion. If the elasticity is exactly one, the good is said to be "unit-elastic".
