The shadow price for a positive decision variable is 0.

Question

Quizplus · Accepted Answer

The shadow price for a positive decision variable is equal to the marginal value of increasing the variable by one unit, and it can never be zero unless the objective function coefficient for that variable is also zero. Thus, if the shadow price for a positive decision variable is zero, it means that the variable is non-binding and its value can be increased or decreased without affecting the optimal objective value.
