chambers as arising from a combination of two phenomena:(a) the choice of individuals to …

We consider an information design problem in which a sender tries to persuade a receiver
that has “correlation neglect,” ie, fails to understand that signals might be correlated. We …

Forecast aggregation combines the predictions of multiple forecasters to improve accuracy.
However, the lack of knowledge about forecasters' information structure hinders optimal …

We present a decision-theoretic analysis of an agent's understanding of the
interdependencies in her choices. We provide the foundations for a simple and flexible …

Decisions under uncertainty are often made with information whose interpretation is
uncertain because multiple interpretations are possible. Individuals may perceive and …

I study the problem of a persuader who proposes a set of models to manipulate how a
boundedly rational agent interprets observable signal realizations. The persuader does not …

Abstract Information provision is a significant component of business-to-business interaction.
Furthermore, the provision of information is often conducted bilaterally. This precludes the …

The problem of aggregating expert forecasts is ubiquitous in fields as wide-ranging as
machine learning, economics, climate science, and national security. Despite this, our …

When multiple sources of information are available, any decision must take into account
their correlation. If information about this correlation is lacking, an agent may find it desirable …

We consider a decision aggregation problem with two experts who each make a binary
recommendation after observing a private signal about an unknown binary world state. An …
