In Porter's framework, which force concerns the bargaining power of buyers?

• A. The bargaining power of buyers refers to customers' ability to influence price and terms.
• B. The threat of new entrants.
• C. The threat of substitutes.
• D. The intensity of rivalry among existing firms.

Answer: (A)

Porter's framework examines how different forces shape profitability, including how buyers can influence price and terms. The force that concerns the bargaining power of buyers is precisely this: how much customers can pressure sellers on price, quality, and contract terms. This power grows when buyers are concentrated, switch costs are low, products are standardized, or good substitutes exist, which can squeeze margins for the seller. The option that states customers' ability to influence price and terms captures this dynamic directly. Other forces describe different aspects: the threat of new entrants relates to barriers to entering the market, the threat of substitutes concerns alternative products that could replace your offering, and the intensity of rivalry among existing firms measures competition among current players. So the description of buyers’ ability to influence price and terms is the best fit.
