Restrictive Practices in the Building Industry
Steps:
- Define restrictive practices as agreements that limit competition, such as price fixing or market sharing, often regulated by antitrust laws.
- Review each option to identify anti-competitive behavior versus normal market activities.
- Eliminate options involving legitimate business actions like purchasing land or bidding.
- Select the option showing collusion among suppliers to control prices.
Why B is correct:
- Price fixing by suppliers violates antitrust laws, like the Sherman Act, as it restricts free market competition and harms consumers.
Why the others are wrong:
- A: Land purchase is a standard business transaction, not restrictive.
- C: Competitive bidding promotes fair market practices, not collusion.
- D: Using varied suppliers encourages competition, not restriction.
Final answer: B
