α: calibrated so average coauthorship-adjusted count equals average raw count
We propose and analyze a general model of simple preference intensity comparisons. The model encompasses those that belong to the utility-difference class, has transparent behavioural underpinnings and features purely ordinal uniqueness properties. Its empirical content is characterized by an easily testable condition on dual behavioural data that include choices and additional observables with intensity-revealing potential that are often elicited in experimental/empirical work, such as survey ratings, response times or willingness to pay.
