We present a striking example of the deconstruction and reconstruction of an anomaly. In line with previous experiments we show in a one-shot setting that the allegedly robust false consensus effect disappears if representative information is readily available. But the effect reappears if a...

We present results of an experiment on expectation formation in an asset market. Participants to our experiment must provide forecasts of the stock future return to computerized utility-maximizing investors, and are rewarded according to how well their forecasts perform in the market. In the...

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...

Models with heterogeneous interacting agents explain macro phenomena through interactions at the micro level. We propose genetic algorithms as a model for individual expectations to explain aggregate market phenomena. The model explains all stylized facts observed in aggregate price fluctuations...

We use economic experiments to examine the nature of relational trading under a menu of incomplete contracts ranging from the repeat purchase mechanism of Klein and Leffler (1981) to highly incomplete contracts that are completely unenforceable by third-parties. Our results suggest that, with...

This discussion paper led to a publication in the 'European Economic Review' (2013). Vol. 61, pp. 186-204.<P> Rational Expectations (RE) models have two crucial dimensions: 1) agents correctly forecast future prices given all available information, and 2) given expectations, agents solve...</p>

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....

In laboratory asset markets, subjects trade shares of a firm whose profits in a linked product market determine dividends. Treatments vary whether dividend information is revealed once per period or in real-time and whether the firm is controlled by a profit-maximizing robot or human subject....

During the last two decades, laboratory experiments have come into increasing prominence and constitute a popular method of research to examine behavioral outcomes and social preferences. However, it has been debated whether results from these experiments can be extrapolated to the real world...
