This paper studies the question of maximization of expected utility from terminal wealth in a multidimensional jump-diffusion model of incomplete market. The special feature of our approach is that the investor only observes the vector of stock prices leading to a partial information framework....

This study investigates the effects of fundamentals ambiguity and guidance credibility on analyst forecast revisions and manager guidance truthfulness. We manipulate earnings probability precision and managers' (ex ante) guidance credibility in an experiment with an embedded sender-receiver...

This paper reports on two experiments that test the descriptive validity of ambiguity models using a natural source of uncertainty (the evolution of stock indices) and both gains and losses. We observed violations of probabilistic sophistication, violations that imply a fourfold pattern of...
