Types of price elasticity of supply As with the price elasticity of demand, the value of price elasticity of supply can range from zero to infinity and can be graphically represented as follows: Perfectly inelastic supply: es = 0 Inelastic supply: 0 < es < 1 Unit elastic supply: es = 1 Elastic supply: 1 < es < ∞ Perfectly elastic supply: es = ∞
