Final answer:
To evaluate a new service using the utility model, both conjoint analysis and discrete choice analysis are employed to understand consumer preferences and predict choice behavior.
Step-by-step explanation:
The methods used to evaluate a new service using the utility model include conjoint analysis and discrete choice analysis. Both methods aim to measure consumer preferences and predict consumer choices by evaluating trade-offs between different product attributes or features in a controlled analysis setting. Conjoint analysis is used to assess the value placed on the features of a product or service by having participants rank or rate a series of alternatives that vary in several attributes.
Discrete choice analysis, on the other hand, focuses on the choices made by individuals from sets of alternatives and allows the evaluation of preferences across discrete options. The combination of both these methods can provide a comprehensive understanding of consumer decision-making and preference structure. The best fit analysis is not commonly used for this purpose, so the correct answer is that both conjoint analysis and discrete choice analysis are used to evaluate a new service using the utility model.
