The thoughts and behaviors of financial market participants depend upon adopted cultural traits, including information signals, beliefs, strategies, and folk economic models. Financial traits compete to survive in the human population, and are modified in the process of being transmitted from...

We offer a new social approach to investment decision making and asset prices. Investors discuss their strategies and convert others to their strategies with a probability that increases in investment returns. The conversion rate is shown to be convex in realized returns. Unconditionally, active...

Social networks and social interactions affect individual and social norms. We develop a direct test of this using Dutch survey data on how respondents evaluate work disability of hypothetical people with some work related health problem (vignettes). We analyze how the thresholds respondents use...

The dynamic behavior of security prices is studied in a setting where two agents trade strategically and learn over time from market prices. The model introduces an information structure which is intended to capture the notion that information is difficult to interpret. Strategic interaction and...

The role of data analysis in communication, persuasion, and decision-making is discussed. Some problems with current data-analysis practice are presented, including communication, complex models, large data bases, one-pass processing, rigid assumptions, resistance, validity, prior information,...

Information is a crucial ingredient in economic decision making. Yet measuring the extent of information exchange among individuals and its effect on economic outcomes is a difficult task. We use the universe of de-identified cellphone usage records from more than one million users in a Chinese...

We investigate models of cheap talk, information disclosure, and Bayesian persuasion, in a unified experimental framework. Our umbrella design permits the analysis of models that share the same structure regarding preferences and information, but differ in two dimensions: the rules governing...

New surveys provide a wealth of information on how economic agents form their expectations and how those expectations shape their decisions. We review recent evidence on how changes in macroeconomic expectations, particularly inflation expectations, affect households' and firms' actions. We show...

Bargaining breakdown--whether as delay, conflict, or missing trade--plagues bargaining in environments with incomplete information. Can a bargaining environment that facilitates or restricts communication alleviate these costs? We exploit a unique opportunity to study this question using real...

Starting from a set of facts on the timing of stock returns relative to Federal Reserve decision-making, I argue that informal communication - including unattributed communication -- plays a central role in monetary policy communication. This contrasts with the standard communications framework...
