The Constant Profit-Maximizing Markup (μ) as a Price-Setting Rule

In economic models that assume a constant intensity of competition, the price elasticity of demand (PED) faced by a firm does not vary with its output. Consequently, the firm's profit-maximizing markup, which is the inverse of the PED, is also constant. This constant markup is denoted by μ\mu (mu), where μ=1PED\mu = \frac{1}{\text{PED}}. A firm operating under these assumptions would set its price based on this fixed markup.
