We introduce the speculation elicitation task (SET) to measure speculative tendencies of individuals. The resulting SET-score allows us to investigate the role of individual speculative behavior on experimental asset market bubbles. The experimental results show that overpricing in asset markets...

The work of Friedrich Von Hayek contains several testable predictions about the nature of market processes. Vernon Smith termed the most important one the ‘Hayek hypothesis’: equilibrium prices and the gains from trade can be achieved in the presence of diffuse, decentralized information,...

The work of Friedrich Von Hayek contains several testable predictions about the nature of market processes. Vernon Smith termed the most important one the ‘Hayek hypothesis’: the gains from trade can be realized in the presence of diffuse, decentralized information, and in the absence of...

In extant financial market models, including the Black-Scholes’ contruct, the dramatic events of October 1987 and August 2007 are totally unexpected, because these models are based on the assumptions of ‘independent price fluctuations’ and the existence of some ‘fixed-point...

The seminal work of Smith Suchanek and Williams (1988) finds price bubbles are frequently observed in an experimental asset market where a single asset with a finite lifetime is traded. Ever since, many studies have been carried out to understand the reason why bubbles occur in such an...

This paper studies the effects on the asset price of the introduction of a public signal in the presence of asymmetric private information in a decentralized market. We introduce an artificial market model populated by boundedly rational agents with heterogeneous levels of reasoning:...

We study the formation of price bubbles on experimental asset markets where cash earns interest. There are two main conclusions. The first is that paying positive interest on cash is ineffective in diminishing bubbles through the reducing-active-participation channel. The second is that the...

This paper investigates the conventional wisdom that market competition for the rights to perform decision-making tasks improves aggregate performances in all relevant tasks by diverting decision rights to individuals who are better able to utilise them. To do so, I use an experiment that embeds...

We consider the consumption-based asset-pricing model, derive a modified basic pricing equation, and present its successive approximations using the Taylor series expansions of the investor’s utility during the averaging time interval. For linear and quadratic Taylor approximations, we derive...

We consider the time interval Δ during which the market trade time-series are averaged as the key factor of the consumption-based asset-pricing model that causes modification of the basic pricing equation. The duration of Δ determines Taylor series of investor’s utility over current and...
