A conceptual and methematical model was developed to study the preparation of persons holding Bachelor's, Master's and Doctoral degrees and to discover the proportion of them who assume academic positions. Data were collected on the number of US and foreign engineering students enrolled, degrees granted, and their employment in academic, industrial, governmental and other sectors of the national economy. The model, consisting of over 200 non-linear difference equations, was programmed for computer simulation and validation against data collected. It broke down the academic sector into undergraduate, master's, doctoral and post-doctoral programs; each of the other sectors were broken down according to the highest degree held by their employees. Project objectives included a study of the dynamics of employment in higher education, interrelationships of academically trained manpower with the rest of the economy, the usefulness of available data, the impact of inflow and outflow of foreign nationals on US economy, and the impact of development in educational technology upon the manpower redistributions in the economy. The overall aim was to determine future manpower needs and set national standards for higher education in order to meet those needs. Software problems which developed with the Burroughs B500 computer installation were not resolved and the simulation results were inconclusive. A supplementary final report will be submitted upon completion of current work. (WM)
