| Abstract: | Conclusion In this paper I have tried to bring together various forms of input-output accounting and analysis suited to dynamic problems. In the usual, static accounting system, the entries all relate to a single time-period and the set of accounts is completely closed. In the alternative, dynamic system suggested here, the inputs for a given period come, either in whole or in part, from the preceding period and the outputs go, either in whole or in part, to the succeeding period.Two types of model can be built within the framework of this dynamic accounting structure: the conventional input-output model, in which the input coefficients are fixed; and an allocation model, in which the output co-efficients are fixed. The conventional model is appropriate to the analysis of production flows; the allocation model to that of demographic flows. These two models provide us with the main building blocks for an educational model, since as far as the human inputs are concerned the educational system is simply a partition of the demographic system, and as far as the economic inputs are concerned it is a partition of the productive system. A first attempt at combining the two was described in my earlier article. |
