This paper critically examines the theory of public policy implementation, discusses the issues of policy implementation studies and examines the applicability of such theory. The first generation implementation researchers find out the problems of policy implementation, i.e. uncertain relationship between policies, decisions and implemented programs. Similarly, the second generation implementation studies focus on the `development of an analytical framework of implementation', which includes the top-down, bottom-up perspectives and their synthesis. Therefore, the third generation implementation research should concentrate on explicit implementation theory-building, which has not yet been realized. - Reproduced.
