When quantifying spillover effects among technologies and between science and technology one faces the problem that clear-cut measurement procedures are difficult to define and to validate. The well-known approach by indexing certain outputs (patent documents) grasps only parts of the complex...

We tackle three components of evolutionary modelling: payoffs, dynamical systems and equilibrium concepts. Firstly, we merely require that fitness functions are continuous. Secondly, we examine very general classes of dynamics. Thirdly, we give useful parallels to the Nash equilibrium and the...

An economic system which exhibits chaotic behaviour has been stabilized on various periodic orbits by use of the Ott-Grebogi-Yorke method. This procedure has been recently applied to controlling chaotic phenomena in physical, chemical and biological systems. We adopt this method successfully for...

In an evolutionary dynamic economic theory the accumulation of durable goods (i.e., wealth) is a key feature. Here we show that the wealth of individual economic agents can be measured by the progress function (PF). PF is a function of goods and money under straightforward assumptions, notably...

This paper uses the biological concepts of heterochrony and K- and r-strategies to construct an economic theory about industry life cycles and trade policy. Relations between various types of heterochrony and different competitive environments provide a general explanation for the Japanese and...

Technological innovations have been investigated by means of substitution and diffusion as well as evolution models, each of them dealing with different aspects of the innovation problem. In this paper we follow the well-known research traditions on self-organization models of complex systems....

This article is a review essay on Stolper's recent book, Joseph Alois Schumpeter, The Public Life of a Private Man. The author recommends the book for a broad readership, although he raises a few critical observations.
