Benjamin Franklin's original maxim found in Poor Richard's Almanac was actually "A penny saved is two pence clear" rather than the more commonly known "A penny saved is a penny earned." We believe he was getting at the notion that one risk-free penny is worth two pennies of expected but...

We examine voluntary disclosure when the firm (“sender”) is risk-averse and uncertain about audience preferences. We show that some firms stay silent in equilibrium, in contrast to classic “unravelling” results. Silence reduces the sensitivity of a firm's payoff to audiences'...

Behavioral biases like disposition effect and overconfidence have received much attention as a potential driver of numerous anomalies observed in the markets. Also, it has been argued that information uncertainty tends to exacerbate these biases and induce stronger irrational behavior among...

Why are stock prices much more volatile than the underlying dividends? The excess volatility of prices can in principle be attributed to two different causes: time-varying discount rates for expected future dividends, arising from variation in risk premia; or the irrational exuberance of...

What would you do if you were invited to play a game where you were given $25 and allowed to place bets for 30 minutes on a coin that you were told was biased to come up heads 60% of the time? This is exactly what we did, gathering 61 young, quantitatively trained men and women to play this...

In a financial market where agents trade for short-term profit and where news can increase the uncertainty of the public belief, there are strategic complementarities in the acquisition of private information and, if the cost of information is sufficiently small, a continuum of equilibrium...

We present a novel approach to finite Rational Inattention (RI) models based on the ignorance equivalent, a fictitious action with state-dependent payoffs that effectively summarizes the optimal learning and conditional choices. The ignorance equivalent allows us to recast the RI problem as a...

This paper presents a general framework for constructing and solving the multivariate static linear quadratic Gaussian (LQG) rational inattention tracking problem. We interpret the nature of the solution and the implied action of the agent, and we construct representations that formalize how the...

Consider an investment problem with strategic complementarities and incomplete information about returns. This paper shows that investors aggregate their private information in equilibrium by trading a token and observing its market price over multiple rounds before making the investment...

In the seminal rational inattention model of Matĕjka and McKay (2015), logit demand arises from the discrete choice of agents who are uncertain about choice payoffs and have access to a flexible, costly information acquisition technology (RI-logit). A notable limitation of this powerful...
