I'm doing a study where one of the attributes is pricing and the levels are various pricing models. Some of them are flat rates, while others are two-part tariffs. That means, people pay a (monthly) access fee and marginal fee for usage (e.g 10 dollar fixed + 0,80 cents per time the service is used).
I would like to measure the relative preference for various combinations of fixed and variable fees in the two-part tariff, for example comparing the preference between a high fixed rate in combination with a low variable rate versus a low fixed rate with a high variable rate. However, this preference of respondents will be dependent on their expected usage and not on their preference for the configuration of the tariff per se. Any suggestions how to account/solve for this?
Help would be appreciated, thanks a lot!
