Description:: This dissertation comprises three essays that study dynamic decisions under uncertainty--in particular, ambiguity. The first two chapters develop new decision models that emphasize the role of making statistical inferences in decisions. The third chapter highlights, in the context of persuasion, how different decision models can lead to distinct conclusions in...

Description:: To survive, animals, including human beings, have developed an amazing ability to learn the constantly changing environment. Specifically, detecting specific odorants in a noisy, variable background is crucial for finding food and water, mating, and avoiding potential dangers. For this purpose, rodents have developed an olfactory system that is powerful...
