A Model of Demographic and Economic Processe Interaction

This paper gives a description of fertility influence on education level of population and its well-being. We carry out the consideration by a demographic model keeping age structure. We suppose that (i) a part of GDP ia used for investment in education, (ii) the production level depends on the education level, and (iii) the pollution ia directly prportional to the size of population. We are carrying on research on the dependence of average consumption on demographic structure of the population for an industrialised economy. in the model each age group of population has different skilled level determined by education and different level of potential labour productivity. The education level is complitly determined by education expenditures. We have found the relation between the value of average consumption of population and the children adults ratio, share of education expenditures in GDP. We have found that yhe quality of life can be improved by descrease of the population size not only ecologically but also economically.
