In a probabilistic model, increasing the service level typically has which effect on consumer surplus, assuming willingness to pay remains constant?

• A. Consumer surplus remains unchanged because service level does not affect perceived value.
• B. Consumer surplus decreases because higher service levels reduce willingness to pay.
• C. Consumer surplus increases because consumers receive more value for the same price.
• D. Consumer surplus becomes negative as service level increases.

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the concept of consumer surplus. Consumer surplus is the difference between what consumers are willing to pay for a good or service and what they actually pay. It measures the net benefit to consumers from purchasing a product.
2. Step 2: Recognize that the willingness to pay remains constant in this problem, meaning the maximum price consumers are ready to pay does not change with service level.
3. Step 3: Consider the effect of increasing the service level. A higher service level typically means consumers receive more value or utility from the product or service without an increase in price.
4. Step 4: Since the price remains the same and the perceived value increases due to better service, the difference between willingness to pay and actual price (consumer surplus) increases.
5. Step 5: Conclude that increasing the service level, while holding willingness to pay constant, leads to an increase in consumer surplus because consumers gain more value for the same price.
