Operations-research workers have not met with much success in being accepted as integral members of regional-health-planning teams, owing in part to a lack of understanding by health planners of the skills the operations researcher has to offer and in part the analyst's inability to demonstrate that he can close the gap between theoretical modeling and the implementation of his results. This paper explores the growth of regional health planning in the United States and highlights its important problem areas. The literature of operations-research applications to health planning is reviewed critically with respect to the feasibility of models and the appropriateness of assumptions. Specific problems with the types of studies currently in the literature are identified and recommendations are made for improved coordination between operations-research workers and health planners.

The article deals with the functional relation between national income and saving or consumption as derived from statistical analysis of data for the United States covering the past two decades. One may gain a much better understanding of how the yearly equilibrium of total saving and investment happens to have been struck at the levels of gross national income prevailing during each of the past twenty years if the component elements of investment and how they are related to income and other factors are deeply analyzed. It has also been investigated that what investment would be likely to be more under stable conditions if the economy operates at a steady increasing rate of production and income. The article concluded that the phase of the housing cycle is a major factor related to the amount of investment and is at least a minor factor related to the level of the saving function. The quantity of current income spent privately for permanent capital goods under conditions of fluctuating activity has responded to previous profits, but has been conditioned by the current level of income, while the income spent for temporary private investment has been related to the direction and extent of change of the level of income.
