Traditional finance is built on the rationality paradigm. This chapter discusses simple models from an alternative approach in which financial markets are viewed as complex evolutionary systems. Agents are boundedly rational and base their investment decisions upon market forecasting heuristics....

This experiment compares the price dynamics and bubble formation in an asset market with a price adjustment rule in three treatments where subjects (1) submit a price forecast only, (2) choose quantity to buy/sell and (3) perform both tasks. We find deviation of the market price from the...

We experimentally investigate how price expectations are formed in a large asset market where subjects' only task is to forecast the future price of a risky asset. The realized prices depend on these expectations. We observe small (6 participants) and large markets (about 100 participants). In...

The study at hand deals with the expectations of professional analysts and novices in the context of foreign exchange markets. We analyze the respective forecasting accuracy and our results indicate that there exist substantial differences between professional forecasts and judgmental forecasts...

Experimental asset markets provide a controlled approach to studying financial markets. We attempt to replicate 17 key results from four prominent studies, collecting new data from 166 markets with 1,544 participants. Only 3 of the 14 original results reported as statistically significant were...

In a pre-registered laboratory asset market study, we investigate dynamics of asset markets with zero (or close to zero) fundamental values. We introduce the "greater fool asset market game" with a zero-value token, whose price doubles in each period. We design several treatments, which differ...

We study the effect of ambiguity on the formation of bubbles and on the occurrence of crashes in experimental asset markets à la Smith, Suchanek, and Williams (1988). We extend their framework to an environment where the fundamental value of the asset is ambiguous. We show that, when the...

We investigate the impact of trader and cash inflow on bubble formation in asset markets with a novel design featuring heterogeneous information and a constant fundamental value. Implementing seven treatments we find that (i) only the joint inflow of traders and cash triggers bubbles...
