This paper studies static rational inattention problems with multiple actions and multiple shocks. We solve for the optimal signals chosen by agents and provide tools to interpret information processing. By relaxing restrictive assumptions previously used to gain tractability, we allow agents...

Adding a stage of signal acquisition to the expected utility model shows that Bayesian updating results in a well defined law of demand for financial information when asset return distributions are conjugate priors to signals such as in the gamma-Poisson case. Signals have a positive marginal...

This paper provides a microfounded information acquisition technology based on a simple framework with information search. When searchable information is limited, an agent encounters increasingly more redundant information in his search for new information. Redundancy slows down the learning...

We provide new empirical evidence on investors' firm-level trading behavior in response to daily changes in stock ambiguity-Knightian uncertainty. The effect of ambiguity is distinct from and contrasts with the well-documented effect of risk, and shares a similar economic significance. An...

For US investors, international equity exposure has never been so readily available at such a low cost. Nonetheless, surveys indicate US investors typically allocate 80–85% of their equity holdings to US equities, much higher than their proportion of global market value. In this note we...

We show that benchmark-linked convex incentives can lead risk-averse money managers aware of mispricing to over-invest in overpriced securities. In the model, the managers' risk-seeking behavior varies in response to the interaction of mispricing with convexity and benchmarking concerns....

We provide a model that can explain empirically relevant variations in confidence and risk taking by combining horizon-dependent risk aversion (“anxiety”) and selective memory in a Bayesian intrapersonal game. In the time series, overconfidence is more prevalent when actual risk levels are...

There has been considerable research into dynamic global tactical asset allocation (GTAA) strategies driven by simple measures of Valuation and Momentum applied to a baseline balanced portfolio of equities and fixed income (see Blitz and van Vliet 2008, Wang and Kochard 2011, Gnedenko and Yelnik...
