Natural Expectations and Macroeconomic Fluctuations

Andreas Fuster

A large body of empirical evidence suggests that beliefs systematically deviate from perfect rationality. Much of the evidence implies that economic agents tend to form forecasts that are excessively influenced by recent changes. We present a parsimonious ...

Elicitation and Modeling of Operational Human Decision Making in a Supply Chain Context

Souleïman Naciri

Supply chains (SC) are complex systems in which human beings play a key role. Whereas human impact is often taken into account in simulation models in terms of physical flows (material handling, fabrication), it is far less the case in terms of information ...

The Role of Game Theory in Key Agreement Over a Public Channel

Michael Christoph Gastpar

In this work we study the problem of key agreement over a public noiseless channel when Alice, Bob and Charlie observe discrete memoryless sources of an unknown distribution. Alice and Bob want to agree on a key K-AB that is protected from Charlie. At the ...

Essays on individual decision making under uncertainty

Elise Le Nestour

This research project is an experimental study of decision-making in very difficult contexts resembling those encountered in financial markets. The starting point was the empirical observation that financial assets are objects of a very complex kind. Speci ...

On the Impact of Bounded Rationality in Peer-to-Peer Networks

Hyung Gon Park

In this letter, we consider peer-to-peer (P2P) networks, where multiple peers are interested in sharing their content. In the considered P2P system, autonomous and self-interested peers use a Markov Decision Process (MDP) framework to determine their uploa ...

A Comparison of Techniques for Sampling Web Pages

Monika Henzinger, Eda Baykan

As the World Wide Web is growing rapidly, it is getting increasingly challenging to gather representative information about it. Instead of crawling the web exhaustively one has to resort to other techniques like sampling to determine the properties of the ...

Mechanisms for Making Crowds Truthful

Boi Faltings, Radu Jurca

We consider schemes for obtaining truthful reports on a common but hidden signal from large groups of rational, self-interested agents. One example are online feedback mechanisms, where users provide observations about the quality of a product or service s ...

Effective Usage of Computational Trust Models in Rational Environments

Karl Aberer

Reputation-based trust models based on statistical learning have been intensively studied for large-scale distributed systems whereas practical application of game-theoretic approaches using sanctioning are still very little understood in such settings. Th ...

Effective Usage of Computational Trust Models in Rational Environments

Karl Aberer

Reputation-based trust models using statistical learning have been intensively studied for distributed systems where peers behave maliciously. However practical applications of such models in environments with both malicious and rational behaviors are stil ...

Social Software Modeling and Mashup based on Actors, Activities and Assets

Denis Gillet, Christophe Salzmann, Evgeny Bogdanov

Despite the extreme diversity of Web applications, one can find similarities among them. This paper proposes an answer to the question of knowing whether it is possible to conceptually represent different Web applications in a common manner such that they ...
