Are stock markets really like beauty contests? - Empirical evidence of higher order belief's impact on asset prices

The goal of this paper is to assess, for the first time, the empirical impact of "Kaynes' beauty contest", or "higher order belief", on asset price volatility. The paper shows that heterogeneous expectations induce higher order beliefs and that heterogeneous expectation asset pricing models thoretically generate more volatility than rational expectation models. the paper also explains how, with some assumptions on the distribution of puplic and private information, a model with higher order beliefs can be empirically estimated. The model is then applied to annual data of the American stock market. The results shows that a model with higher order beliefs generates a level of volatility in line with the price volatility observed on the market.
