Matching heterogeneous agents with a linear search technology

Nöldeke, Georg; Tröger, Thomas - 2009

Steady state equilibria in heterogeneous agent matching models with search frictions have been shown to exist in Shimer … investigated linear search technology. -- Search ; Matching ; Steady State Equilibrium … and Smith (2000) under the assumption of a quadratic search technology. We extend their analysis to the commonly …

Taking a shower in youth hostels : risks and delights of heterogeneity

Matzke, Christina (contributor); Challet, Damien (contributor) - 2008

Tuning one's shower in some hotels may turn into a challenging coordination game with imperfect information. The temperature sensitivity increases with the number of agents, making the problem possibly unlearnable. Because there is in practice a finite number of possible tap positions, identical...

On two-period committee voting : why straw polls should have consequences

Frommeyer, Tim Julius - 2015

We consider a committee voting setup with two rounds of voting where committee members who possess private information about the state of the world have to make a binary decision. We investigate incentives for truthful revelation of their information in the first voting period. Coughlan (2000)...

Correlation neglect in belief formation

Enke, Benjamin; Zimmermann, Florian - 2013

Many information structures generate correlated rather than mutually independent signals, the news media being a prime example. This paper shows experimentally that in such context many people neglect these correlations in the updating process and treat correlated information as independent. In...

Consistency and communication in committees

Deimen, Inga; Ketelaar, Felix; Quement, Mark T. Le - 2013

This paper analyzes truthtelling incentives in pre-vote communication in heterogeneous committees. We generalize the classical Condorcet jury model by introducing a new informational structure that captures consistency of information. In contrast to the impossibility result shown by Coughlan...

Dynamic voluntary contribution to a public good : learning to be a free rider

Clemens, Christiane; Riechmann, Thomas - 2001

This paper explores the question whether boundedly rational agents learn to behave optimally when asked to voluntarily contribute to a public good. The decision process of individuals is described by an Evolutionary Algorithm. We analyze the learning process of purely and impurely altruistic...

Lernen in ökonomischen Systemen : qualitative Aspekte und Überblick

Clemens, Christiane; Haslinger, Franz - 2001

Dieser Beitrag gibt einen Überblick über Ansatzpunkte und Möglichkeiten zur Integration von Lernprozessen in volkswirtschaftliche Fragestellungen. Es werden alternative Methoden vorgestellt, individuelle aber auch gesellschaftliche Lernenvorgänge in ökonomischen Modellen zu erfassen.

Modellierung von Preiserwartungen durch neuronale Netze

Heinemann, Maik; Lange, Carsten - 1997

Das Papier untersucht, wie Erwartungsbildung mit Hilfe neuronaler Netze modelliert werden kann. Die Grundlage bildet ein Cobweb-Modell, in dem Firmen Preiserwartungen auf Basis eines Feedforward-Netzes bilden. Zunächst wird anhand von Simulationen gezeigt, daß Firmen durch neuronale...

Learning and behavioral stability : an economic interpretation of genetic algorithms

Riechmann, Thomas - 1998

This article tries to connect two separate strands of literature concerning genetic algorithms. On the one hand, extensive research took place in mathematics and closely related sciences in order to find out more about the properties of genetic algorithms as stochastic processes. On the other...

Genetic algorithms and economic evolution

Riechmann, Thomas - 1998

This paper tries to connect the theory of genetic algorithm (GA) learning to evolutionary game theory. It is shown that economic learning via genetic algorithms can be described as a specific form of evolutionary game. It will be pointed out that GA learning results in a series of near Nash...
