Zukunftsfähig konsumieren!

Wie "zukunftsfähig” ist die Konsumgesellschaft? Der Bedarf, aber auch das Po­tenzial für ökologischen Wandel ist im Bereich des privaten Konsums sehr hoch. Wegen des Ziels der Konsumentensouveränität handelt es sich zugleich um eines der schwierigsten Terrains ökologischer Politik. Der Blick auf die für den Konsumbereich relevante ökologische Kommunikation eröffnet Erfolg verspre­chende Ansatzpunkte für eine Förderung des ökologischen Strukturwandels (1)

Agent-based dynamics in disaggregated growth models

This paper presents an agent-based model of disaggregated economic systems with endogenous growth features named Lagon GeneriC. This model is thought to represent a proof of concept that dynamically complete and highly disaggregated agent-based models allow to model economies as complex dynamical systems. It is used here for "theory generation", investigating the extension to a framework with capital accumulation of Gintis results on the dynamics of general equilibrium.Agent-based models, economic growth.

Il s'agit d'un prototype hautement désagrégé et dynamiquement complet qui permet la représentation d'économies comme des systèmes dynamiques complexes. Une application aux résultats de Gintis sur la dynamique des prix est également présentée

Two modes of scheduling in a simple economic agent-based model

International audienceAgent-based models (ABMs), and with them simulation, are gaining importance in economics. As ABMs offer the possibility to consider several equilibria, they can be helpful tools in the attempt at identifying win- win strategies for climate policy. Aiming at a better understanding of economic ABMs (also, but not only as dynamical systems in the mathematical sense), first steps can be made by studying strongly simplified economic ABMs. This paper presents work in progress on an example case: while in economic systems in the real world many actions and interactions by various agents take place in parallel, often ABMs use sequential computation. With a simple economic agent-based model of firms that trade and produce goods, we explore and discuss two alternative modes of scheduling. While one is better suited for working with data from national statistics, the other one dispenses with random shuffling that is often introduced to avoid a bias between agents which arises from sequential computations

A multi-agent model of several economic regions

International audienceThis paper presents Lagom regiO: a multi-agent model of several growing economic areas in interaction. The model is part of the Lagom model family: economic multi-agent models developed to make steps toward understanding equilibrium selection and identifying win-win opportunities for climate policy. The particular feature of the model presented here is that it locates agents in one of a user-chosen number of regions. It can thus be used to represent diverse economic areas by specifying characteristics of agents and their interaction network as depending on their regions
