This paper presents recent developments in model selection and model averaging for parametric and nonparametric models. While there is extensive literature on model selection under parametric settings, we present recently developed results in the context of nonparametric models. In applications,...

This paper investigates the role of persuasion mechanisms in collective decision-making. A biased sender adopts a Bayesian persuasion mechanism to provide a committee of uninformed receivers with signals about the unknown state of the world. We compare public persuasion with private persuasion....

This paper investigates the role of persuasion mechanisms in collective decision-making. A persuasion mechanism consists of a family of conditional distributions over the underlying state space and the generated noisy signals. A biased, perfectly informed sender adopts a persuasion mechanism to...

We develop a new model where the dynamic structure of the asset price, after the fundamental value is removed, is subject to two different regimes. One regime reflects the normal period where the asset price divided by the dividend is assumed to follow a mean-reverting process around a...
