Combining rational choice and evolutionary dynamics : the indirect evolutionary approach

Königstein, Manfred; Müller, Wieland - 1999

In this study we propose a formal framework for the indirect evolutionary approach as initiated by Güth and Yaari (1992). It allows to endogenize preferences and to study their evolution. We define two-player indirect evolutionary games with observable types and show how to incorporate...

Learning to bid : an experimental study of bid function adjustments in auctions and fair division games

Güth, Werner; Ivanova-Stenzel, Radosveta; Königstein, … - 1999

We examine learning behavior in auctions and Fair division games with independent private values under two different price rules, first and second price. Participants face these four games repeatedly and submit complete bid functions rather than single bids. This allows us to examine whether...

Robust learning experiments : evidence for learning and deliberation

Güth, Werner - 2000

Robust learning experiments confront participants with structurally different decision environments which they encounter, furthermore, repeatedly. Since the decision format does not depend on the rules (of game), forward looking deliberation (the shadow of the future) can be detected by...

Limited depth of reasoning and failure of cascade formation in the laboratory

Kübler, Dorothea; Weizsäcker, Georg - 2000

We examine the robustness of information cascades in laboratory experiments. Apart from the situation in which each player can obtain a signal for free (as in the experiment by Anderson and Holt, 1997, American Economic Review), the case of costly signals is studied where players decide whether...

On the regulation of social norms

Kübler, Dorothea - 2000

A model is developed to understand how norms can be influenced by "norm entrepreneurs", e.g. lawmakers, government agencies, unions etc. Two instruments of influencing the dynamics of normfollowing behavior are analyzed, namely transforming the (monetary) incentives and changing the meaning or...

From full to bounded rationality : the limits of unlimited rationality

Güth, Werner; Kliemt, Hartmut - 2001

choice making. We illustrate why this role is not being fulfilled well by standard models of full rationality and that … theories of bounded rationality are needed not only for better predictions, but also for developing better advice. Our main … point is that one cannot succeed here without studying how theories of bounded rationality causally influence the behavior …

Capacity choices and price competition in experimental markets

Anderhub, Vital; Güth, Werner; Kamecke, Ulrich; … - 2001

In the heterogeneous experimental oligopoly markets of this paper, sellers first choose capacities and then prices. In equilibrium, capacities should correspond to the Cournot prediction. In the experimental data, given capacities, observed price setting behavior is in general consistent with...

Through trial & error to collusion

Huck, Steffen; Oechssler, Joerg; Normann, Hans-Theo - 1999

In this note we study a very simple trial & error learning process in the context of a Cournot oligopoly. Without any knowledge of the payoff functions players increase, respectively decrease, their quantity by one unit as long as this leads to higher profits. We show that despite the absence of...

Does cascade behavior in information cascades reflect Bayesian updating? : an experimental study

Oberhammer, Clemens; Stiehler, Andreas - 2001

Updating behavior in cascade experiments is usually investigated on the basis of urn prediction. But urn predictions alone can only provide a very rough information on individual updating behavior. Therefore, we implement a BDM mechanism. Subjects have to submit maximum prices that they are...

Simultaneous over- and underconfidence : evidence from experimental asset markets

Maciejovsky, Boris; Kirchler, Erich - 2001

In this paper individual overconfidence within the context of an experimental asset market is investigated. Overall, 72 participants traded one risky asset on six markets of 12 participants each. The results indicate that individuals were not generally overconfident. Moreover, overconfidence was...
