In this paper we present three simple theoretical models to explain the influence of the possibility to make non-binding announcements on future investment behaviour in public good settings. Our models build on the idea that voluntary contributions to the supply of a public good might be...

In this paper an evolutionary simulation model, based on replicator dynamics, is developed. The purpose is to identify changes in the patterns of evolution of the market structure caused by Information and Communication Technologies (ICT) in the E-conomy in comparison to the Old Economy (without...

Wirtschaften vollzieht sich unzweifelhaft in der Zeit - aber kann man aus dieser Tatsache wirklich einen direkten Analogieschluss zwischen der natürlich-biologischen Evolution und dem Wirtschaftsprozess ziehen? Müßte dazu nicht nur sowohl das begriffliche als auch das methodische Arsenal der...

In contrast to the usual approach taken in the literature, in which an Industry Life Cycle (ILC) is reproduced by aggregate functions, the model of this paper generates a self-organizing ILC. A general evolutionary agent-based simulation model is developed that can be adapted for specific...

Daß ökonomische Prozesse zu den primären evolutorischen Untersuchungsgegenständen gehören und wie alle handlungserzeugten Prozesse, die nicht antizipierte Neuheiten hervorrufen können, grundsätzlich als verlaufs- und ergebnisoffen zu konzipieren sind, ist unstrittig. Um den Problemen des...

The present paper makes a contribution to fill in a gap left open by dynamic theory and evolutionary economics as well. While the "closed loop" dynamic theory has explanation power in analyzing evolving economic systems at the price of neglecting the possible occurrence of non anticipated...

In dem vorliegenden Papier wird untersucht, inwieweit Verbraucherschutz und der Informationsstand von Konsumenten einen Einfluss auf die Entwicklung einer Industrie haben. Hierzu wird das evolutorische Simulationsmodell von Winter (1984) um einen explizit modellierten Konsumsektor in Anlehnung...

EU enlargement offers significant welfare gains to old and new member states. However, these welfare gains do not come automatically but have to be earned by appropriate adjustments in domestic policies. This is particularly relevant for Germany's New Laender, which could benefit from the...

This paper analyses a RBC model in continuous time featuring deterministic incremental development of technology and stochastic fundamental inventions arriving according to a Poisson process. Other than in standard RBC models, shocks are uncorrelated, irregular and rather seldom. In two special...
