Definition of the Firm's Profit Share (σ) in the Price-Setting Model

In the price-setting model, the parameter σ\sigma (sigma) represents the firm's profit share, which is the fraction of output per worker (λ\lambda) that the firm retains as profit. It is a constant with a value between 0 and 1. Consequently, the remaining portion of output, (1σ)(1 - \sigma), represents the share paid to workers as a real wage.
