We examine how professional traders behave in two financial market experiments; we contrast professional traders' behavior to that of undergraduate students, the typical experimental subject pool. In our first experiment, both sets of participants trade an asset over multiple periods after...

I examine how differences in the ability to identify profitable investment opportunities contribute to wealth inequality. I analyze a model of financial markets with investors heterogeneously informed about future returns. The unconditional wealth share distribution features a thick right-tail...

We use experimental markets to examine how pushing investment information and the value relevance of that information interact to influence investors’ value estimate accuracy and market price efficiency. Developments in technology allow information to be pushed to investors anytime and...

In our model, senders' propensity to discuss their strategies' returns, and receivers' propensity to be converted, are increasing in sender return. A distinctive implication is that...

We analytically show that a common across rich/poor individuals Stone-Geary utility function with subsistence consumption in the context of a simple two-asset portfolio-choice model is capable of qualitatively and quantitatively explaining: (i) the higher saving rates of the rich, (ii) the...

This study examines the role of actual and perceived financial sophistication (i.e., financial literacy and confidence) for individuals' wealth accumulation. Using survey data from the German SAVE initiative, we find strong gender- and education-related differences in the distribution of the two...
