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....

We report the results of an experiment designed to study the determinants of asset price movement and consumption smoothing behavior across asset markets populated with varying proportion of traders with and without having induced motive to smooth consumption. Although the asset is over-priced...

We investigate the effect of gender on the price deviation (bubble) from the fundamental value in a learning-to-forecast experiment. Our results show that gender plays a more prominent role in markets with positive expectation feedback than in markets with negative feedback. In both types of...

We investigate expectation formation in a controlled experimental en-vironment. Subjects are asked to predict the price in a standard asset pricingmodel. They do not have knowledge of the underlying market equilibrium equa-tions, but they know all past realized prices and their own predictions....

Notwithstanding the recognized importance of traders' expectations in characterizing the observed market dynamics, for instance the formation of speculative bubbles and crashes on financial markets, little attention has been devoted so far by economists to a rigorous study of expectation...

The experiment engaging 50 participants was performed to model and identify the determinants of the players’ risky behavior. Here, a questionnaire and a bimatrix game containing the negative/zero payoffs were used to identify the players’ motives to play risky strategies. Besides the...

In experimental games, a substantial minority of players often fail to best respond. Using two-person 3x3 one-shot games, we investigate whether ‘structuring' the pre-decision deliberation process produces greater consistency between individuals' stated values and beliefs on the one hand and...

We study the emergence of bubbles in a laboratory experiment with large groups of individuals. The realized price is the aggregation of the forecasts of a group of individuals, with positive expectations feedback through speculative demand. When prices deviate from fundamental value, a random...

The way in which individual expectations shape aggregate macroeconomic variables is crucial for the transmission and effectiveness of monetary policy. We study the individual expectations formation process and the interaction with monetary policy, within a standard New Keynesian model, by means...

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...
