Experimental evidence has consistently confirmed the ability of uninformed traders, even novices, to infer information from the trading process. We hypothesized that ToM was involved after contrasting brain activation in subjects watching markets with and without insiders. ToM refers to the...

It is shown here that the existence of a time variable risk premium cannot be tested without additional specification as to how such a premium should be related to observable variables. Recent empirical results are discussed in this context and it is argued that no conclusive evidence of a time...

This monograph sets the stage for experiments by first examining a sample data set that looks very much like the typical historical data one gathers from the field, only it was actually generated in the laboratory so that we know what really went on. The example demonstrates how misleading the...

We present a theory and experimental evidence on pricing and portfolio choices under asymmetric reasoning. We show that under asymmetric reasoning, prices do not reflect all (types of) reasoning. Some agents who observe prices that cannot be reconciled with their reasoning switch from perceiving...

This paper reports on experimental tests of an instantiation of the Lucas asset pricing model with heterogeneous agents and time-varying private income streams. Central features of the model (infinite horizon, perishability of consumption, stationarity) present difficult challenges and require a...

Financial decision making is the outcome of complex neurophysiological processes involving, among others, constant re-evaluation of the statistics of the problem at hand, balancing of the various emotional aspects, and computation of the very value signals that are at the core of modern economic...
