The study of how solutions of LPs change when you change the LP is called sensitivity analysis, and we've already seen some of it: the marginal values theorem tells us something about what happens in a standard form LP if you change the right-hand sides of the constraints. Say the change in the coefficient is within the allowable increase or decrease. The amount by which an objective function coefficient can be increased with the current basis remaining optimal.
