In this paper the choice between public and private provision of goods and services is considered. In practice, both modes of operation involve significant delegation of authority, and thus appear quite similar in some respects. The argument here is that the main difference between the two modes concerns the transactions costs faced by the government when attempting to intervene in the delegated production activities. Such intervention is generally less costly under public ownership than under private ownership. The greater ease of intervention under public ownership can have its advantages; but the fact that a promise not to intervene is more credible under private production can also have beneficial incentive effects. The fundamental privatization theorem (analogous to the fundamental theorem of welfare economics) is presented, providing conditions under which government production cannot improve upon private production. The restrictiveness of these conditions is evaluated. 相似文献

This study is an extension of a previous evaluation of a program (Red Flag/Green Flag) in which children, parents, and teachers were exposed to a workbook and film designed to teach personal safety strategies for preventing sexual victimization or encouraging adult assistance through disclosure of such incidents. In the current investigation, only children and their teachers received this didactic training program. Children and teachers from neighboring schools were assigned to a Training or Control group. Self-reports from children, teachers, and parents, as well as guidance counselor incident reports, were obtained to evaluate outcome. Results indicated greater gains in general knowledge and prevention skills at post-training and 6-month follow-up for trained than control children. Some improvements were made by trained teachers and parents of trained children. Child reports of personal experiences and guidance counselor incident reports were in accord with the assistance component of the program. However, the pattern of reports across sources is difficult to interpret. The findings are discussed in light of salient issues regarding the content of training, child disclosure, and methodology. 相似文献
