In this paper we develop a micro ecosystem model whose basic entities are representative organisms which behave as if maximizing their net offspring under constraints. Net offspring is increasing in prey biomass intake, declining in the loss of own biomass to predators and Allee's Law applies....

A model of interregional competition for the location of new (production) facilities by a location decision maker (LDM) is analyzed as a differential game. Two regions try to enhance their attraction by making concessions to the LDM in order to raise the probability that a new facility will be...

We discuss the relevance of the concept of rational behavior in economic theory and suggest, on the basis of modern brain research results, to abstain from this notion and instead to apply behavioral rules of thumb in decision-making, especially if these rules can be derived from rational...

This paper introduces aging of workers into the neoclassical theory of labor demand. Among other things, it is shown that under reasonable hypotheses employment, even of younger workers, increases in the span of working life. Using the standard model without aging, the analysis of such issues...

A simple rule of thumb which has been successfully used in the basic neoclassical growth model as an alternative to the unstable dynamic optimization solution is shown to be more generally applicable in a non-scale growth model with learning by doing. The model is formulated in accordance with...

While there are various definitions of public goods, the property of joint consumability has become the main or sole defining characteristic of such goods. Among the other characteristics the property of non-excludability is the one primarily discussed. While it is common in the literature to...

This paper develops a two-sector non-scale growth model and investigates the relationship between international trade, growth, and industrialization. It is shown that the counterfactual prediction of new growth theories regarding a positive effect of population growth on the growth rate of per...

This paper analyzes the dynamics of a two-dimensional microfounded predatorprey model. It is shown that the dynamics closely resemble those of a model commonly used in mathematical biology if parameters of the latter are suitably restricted. The positive equilibrium of the microfounded model is...
