WebJan 8, 2024 · The envelope theorem applies again, but differently. First, because each firm’s quantity of output maximizes its profits in price-taking competitive equilibrium, the envelope theorem implies that the impact on its profits is equal to the direct impact on its costs at fixed quantity, plus the change in output price multiplied by that quantity. WebThe technique to answer this question is the modern envelope theorem, modern in the sense that it does not rely on much about the optimal choice of x, and that the technique is applicable not only to the decision problems studied here but also to the economics of incentives and information. 2 The envelope theorem when X(t) is constant to t
