Description
Three different lines of approach have contributed to the theory of optimal planning. One approach considers the problem from the view-point of a national government and its adviser, the econometrician planning speci alist. The government can, if this is regarded as desirable, stimulate investment in certain directions and discourage other economic activities. By more than a few fiscal devices, it can influence both the total level and the distribution of investment funds over different sectors of production. Also, in many countries, a public agency plays some more or less coordinat ing role in the formulation of long-term plans for output by the enter prises sector; this may range from administrative direction in so-referred to as centrally planned economies, to persuasion and advice in ‘capitalist’ economies. Accordingly, the public planner wishes to know what dis tribution of the nation’s resources would be ‘optimal’. This ends up in the construction of more than a few models that could be described under the general heading ‘input-output type models’. This kind of model has been in large part developed by practitioners, among whom Sandee [B2] is one of the crucial outstanding and the earliest. A later, well-developed example of a model based on this approach is, as an example, the Czech model by Cerny et al. [Bl]. A second approach considers the problem from the point of view of the private entrepreneur and his adviser, the manager and financial accountant.
