People respond to incentives.

Explanation:

People respond to incentives is the principle that illustrates the fact that people start purchasing their alcohol in surrounding states after the state in which they live increases the tax on alcoholic beverages. An incentive is either the possibility of a reward or the possibility of punishment. Incentives are key aspects of the way people act. Rational people decide by evaluating cost and benefits, and they act according to this.
