As part of a larger investigation of the manpower training system, information on 67 manpower agencies located in several New York communities (excluding New York City) was collected during the summer of 1973. This study examines the determinants of agencies' attempts to establish interorganizational linkages that are instrumental to the achievement of their goals. It was found that a smaller agency budget and the need to provide a wide range of services facilitate the establishment of those linkages that are of high instrumental value to the agency. To a lesser extent, the presence of an appropriate decision-making mechanism within the agency and the ability to freely establish and maintain relations with other organizations are also found to be contributing factors. In addition, the study also shows that agencies that maintain linkages of low instumental value with many other organizations feel that they are being dominated by their environment. (Author/MLF)
