Growth structure and environment. 6 contributions to the macro economic model development

This thesis comprises 6 papers on the application of macro economic models to environmental problems. Interactions between the economic and the ecological models are elucidated and a description is given of a possible systematization of of the environmental-economic cycle within a macro economic model. Economic and technological limitations affecting the potential environmental advantages are discussed. In the second part of the thesis the general interdependence of production and consumption, and the various forms of environmental stress is analyzed. For this purpose an environment-related input-output model is presented, where for each industry there are given emissions and/or consumption of natural resources (so-called environmental coefficients), which are likely to originate from the activities of this industry. As examples of macro economic modelling,the nitrogen cycle in Denmark, environmental effects of consumer choice, use of building materials and emission due to energy generation and consumption etc. are analyzed.
