Which technique is commonly used by fraudsters to ensure they can charge inflated prices for their contracts?

The most appropriate technique commonly utilized by fraudsters to charge inflated prices for their contracts is collusion. In collusion, multiple parties work together to manipulate pricing, often secretly agreeing on inflated rates that are then presented as legitimate. This collective agreement allows the involved parties to bypass competitive pricing, leading to inflated contracts that benefit them at the expense of the buyer.

Collusion might involve sharing confidential information about bids, agreeing on pricing strategies, or coordinating bidding activities to suppress competition. This not only leads to higher costs but also limits market competition, which is why it can be particularly harmful in scenarios involving contracting and procurement processes.

Understanding this tactic emphasizes the importance of transparency and competition in the bidding and contract awarding processes, as such fraudulent practices undermine market integrity and fairness.

Other options may involve specific behaviors, but they do not capture the broader scheme and collaboration inherent in collusion that leads to inflated pricing. For instance, underbidding typically refers to a strategy to win contracts by presenting lower prices, while price gouging involves charging excessively high prices during emergencies, not related to contract collusion. Bid shopping, on the other hand, involves a contractor disclosing the bids of subcontractors to negotiate a lower price but does not inherently imply conspiracy to inflate prices.
