When investors disagree and trade on their views about asset returns, market prices reflect the wealth/consumption share weighted average belief about risk premia, where more accurate, risk tolerant, or patient investors carry a larger weight. We explore the properties of this market view, and...

Recessions lead to substantial, yet not immediate drop in output. The low and often negative growth during recessions is typically followed by a steady recovery with abnormally high growth. We propose a theory where a recession is preceded by the introduction of a new risk source. The expected...

We study how disagreement on both factor and stock-specific risk exposures across many agents and securities impact asset prices. Our theoretical analyses predict that disagreement about factor dynamics drives larger flows into portfolios that are more exposed to the factors. Consequently, these...

We define the concept of market beliefs in an economy with disagreement, such that equilibrium in a representative agent economy with market beliefs is equivalent to equilibrium in the disagreement economy. In general, the mapping from individual agent beliefs to market beliefs is complex and...

This study shows that relative price dispersion impacts risk premia. Notably, firms associated with goods and services that have increased (decreased) in price relative to the headline inflation rate earn high (low) returns. We refer to this return spread of 0.71% per month as the relative price...

In a production economy, in which agents have heterogeneous beliefs and a social planner has incomplete knowledge about which beliefs are correct, we introduce the concept of Incomplete Knowledge (IK) efficiency. IK-inefficient allocations can be improved upon without taking a stand on which...

We analyze the performance of irrational investors, who mistake expected returns of assets in a multi-asset economy. Mistakes by probabilistically unsophisticated investors that a priori seem small lead to severe underperformance compared with rational investors, under general conditions. Our...
