Which federal law prohibits practices such as price fixing and group boycotting?

The Sherman Antitrust Act is the federal law that prohibits anticompetitive practices, including price fixing and group boycotting. This legislation was enacted in 1890 to combat monopolies and promote fair competition in the marketplace. By making it illegal for businesses to collaborate on pricing or to collectively refuse to do business with others, the Sherman Act aims to protect consumers and ensure that competition remains healthy, allowing for fair market conditions.

In the context of real estate, this is particularly relevant because real estate professionals must not engage in practices that would manipulate prices or harm competition among agents and brokers. Such actions can lead to artificially inflated prices and limit consumer choices, which is contrary to the principles advocated by the Sherman Antitrust Act. The other laws mentioned, like the Real Estate Settlement Procedures Act, the Fair Housing Act, and the Truth in Lending Act, serve different purposes related to consumer protection and transparency but do not focus specifically on antitrust issues.
