In what way does the government regulate pricing?

What will be an ideal response?

The most important pieces of federal legislation affecting prices are the Sherman, Clayton, and Robinson-Patman acts, initially adopted to curb the formation of monopolies and to regulate business practices that might unfairly restrain trade. Because these statutes can be applied only to interstate commerce, many states have adopted similar provisions for companies that operate locally. Examples include pricing within channel levels and pricing across channel levels.
