Finally, particular conclusions on the underlying reasons for the high model risk and …

Agents who acknowledge that their models are incorrectly specified are said to be ambiguity averse, and this affects the prices they are willing to trade at. Models for prices of commodities attempt to capture three stylized features: seasonal trend, moderate deviations (a diffusive factor), and...

We develop a transparent Bayesian approach to quantify uncertainty about linear stochastic discount factor models. We show that, for a Bayesian decision-maker, the model probability decreases with historical maximum in-sample Sharpe ratios and increases with model dimensions. We apply our...
