Final answer:
Buyer behavior research in the political-legal environment focuses on the impact of Government Regulations on market dynamics, including how they affect competition and consumer choices.

Government actions can include blocking anticompetitive mergers, ending restrictive practices, imposing price cap regulation on natural monopolies, and deregulation to foster competition.
