This paper takes the Dekel, Lipman, and Rustichini (2001) framework, in which subjective beliefs over subjective states cannot be identified, and proves a conjecture made in their paper: if the Bernoulli utility functions are additively separable and one of the terms is state-independent, then beliefs are uniquely identified. The main departure from existing literature is that beliefs are identified without imposing extra objective elements into the model.
