We develop a bioeconomic model to analyze a sole-owner fishery with fixed costs as well as a continuous cost function for the generalized Cobb-Douglas production function with increasing marginal returns to effort level. On the basis of data from the North Sea herring fishery, we analyze the...

Governments around the world seek for strategies to overcome the reliance on fossil resources and provide solutions for the most challenging contemporary global issues: food shortage, depletion of natural resources, environmental degradation and climate change. A very recent and widely diffused...

As emphasised in the beginning, the considerations presented here are very preliminary by nature. Nevertheless, some of the aspects discussed seem worth summarising. First, financial markets worldwide show a tendency of asymmetric regional " clustering" with newly emerging places challenging the...

This paper develops a bio-economic Malthusian growth model. By integrating recent research on allometric scaling, energy consumption, and ontogenetic growth we provide a model where subsistence consumption is endogenously linked to body mass and fertility. The theory admits a two-dimensional...

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...

Building on the philosophy of Charles Sanders Peirce, recent advances in biosemiotics have resulted into a concise framework for the analysis of signs in living systems. This paper explores the potential for economics and shows how biosemiotics can integrate two different research agendas, each...

This paper examines how non-binding co-operative agreements on marine fisheries management can be sustained when management plans in participating countries are implemented with error. The effects of implementation uncertainty on voluntary co-operation are compared to those of recruitment...
