Rational Expectations (RE) models have two crucial dimensions: agents correctly forecast future prices given all available information, and given expectations, agents solve optimization problems and these solutions in turn determine actual price realizations. Experimental testing of such models...

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...

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.

We study which factors in terms of trading environment and trader characteristics determine individual information acquisition in experimental asset markets. Traders with larger endowments, existing inconclusive information, lower risk aversion, and less experience in financial markets tend to...

Using experimental asset markets, we study the situation of a financial analyst who is trying to infer the fundamental value of an asset by observing the market's history. We find that such capacity requires both standard cognitive skills (IQ) as well as social and emotional skills. However,...
