According to Porter's competitive forces model, which force reflects an organization losing customers due to high product prices?

The correct answer is the force that addresses how an organization could lose customers due to high product prices – substitute products and services. This force captures the idea that customers may choose alternatives that provide similar value but at a lower cost. When prices for a particular product or service rise, consumers often look for substitutes that fulfill their needs without the hefty price tag, highlighting the importance of understanding and evaluating competitor offerings.

Businesses must remain cognizant of substitute products because these alternatives can significantly influence customer decisions and market dynamics. If a company’s pricing strategy is not competitive, it may encourage customers to switch to other options, which can erode market share and revenue.

The other forces in Porter's model focus on different aspects of competitive strategy. For example, the threat of new entrants pertains to the barriers to entry in a market, while rivalry among existing competitors addresses the competition within the industry itself. Lastly, the bargaining power of suppliers refers to the influence suppliers have on the price and availability of inputs, but it does not directly relate to customer loss from high product prices. Thus, substitute products and services are the correct focus for this particular scenario.
