We develop a multi-agent framework based on probabilistic cellular automata theory to describe off-equilibrium dynamics in the context of the economic problem of price adjustment in different strategic situations as investigated experimentally by Fehr and Tyran (2001) and (2008). It is found...

The paper revives a theoretical definition of party coherence as being composed of two basic elements, cohesion and factionalism, to propose and apply a novel empirical measure based on spin physics. The simultaneous analysis of both components using a single measurement concept is applied to...

The raise of material efficiency is of special importance in the provision of solutions for a more sustainable path of development. One of the main approaches in this direction is the resource saving closure of material circulations among industrial actors. This means at least: maximum rate of...

In this paper we investigate the interaction between a credit portfolio and another risk type, which can be thought of as market risk. Combining Merton-like factor models for credit risk with linear factor models for market risk, we analytically calculate their interrisk correlation and show how...

In früheren Konjunkturzyklen war zu beobachten, dass sich ein Aufschwung in den Industriestaaten recht gleichmäßig verbreitete, während bei Rezessionen ein weniger ausgeprägter Gleichlauf zu beobachten war. In der derzeitigen Krise ist das allerdings anders: Sie zeichnet sich nicht nur...

Empirical data analysis shows that the business cycles of industrialized nations demonstrate a fairly strong degree of synchronization in periods of growth, and a lesser degree of synchronization during periods of contraction. The current recession, however, breaks this pattern: the business...

The lack of a liquid market for implied correlations requires traders to estimate correlation matrices for pricing multi-asset equity options from historical data. To quantify the precision of these correlation estimates, we devise a block bootstrap procedure. The resulting bootstrap...
