Hank and Jeanine's agreement to send clients to each other is an example of which practice?

The practice being described is a form of territory allocation, which involves an agreement between two or more parties to divide markets or clients in a way that limits competition among them. In this scenario, Hank and Jeanine’s arrangement to send clients to each other shows a cooperative strategy to secure certain territories or client bases, effectively minimizing competition between themselves.

Territory allocation is often viewed as problematic in real estate because it can infringe on fair competition laws and can lead to anti-competitive behavior. Real estate professionals are generally encouraged to compete fairly and openly, as this promotes better services and pricing for consumers.

The other options relate to different unethical practices in real estate. Blockbusting involves inducing homeowners to sell by instilling fear that the neighborhood will decline due to changes in demographics, which is a discriminatory practice. Price-fixing refers to an agreement among parties to set prices at a certain level, violating antitrust laws. Redlining is the practice of denying services, either directly or through selectively raising prices, to residents of certain areas based on racial or ethnic composition. These practices do not relate to the mutual agreement between Hank and Jeanine, reinforcing why territory allocation is the appropriate answer.
