Since the early 1960's, new programs have been developed to prepare poor people for jobs in hospitals, schools, social agencies, and community centers offering human services. To ascertain the cost effectiveness of these programs the Career Options Research and Development (CORD) Project focused on the need for cost and benefit studies that recognize both quantifiable and non-quantifiable variables. It is noted that while ways can be found to average out specific variables, it is not yet possible to measure the variance in relationships between and among variables. Also discussed in terms of cost-benefit analysis are the investment model, the human capital model, and the allocation of resources model. Further areas for research studies are suggested in order to answer questions such as: Under what conditions and in what fields will horizontal mobility have more pay-off than vertical mobility? (JS)
