This article examines constraints in development bureaucracies in intensifying the use of microcomputers as they move beyond processing applications to analysing applications. The work is based on the experience of several ministries of the Government of Kenya. Processing applications involve throughput of data and are relatively simple. Analysing applications, in contrast, are more complex and include data assembly, sensitivity analysis, and modelling. The article argues that processing applications are more compatible with the administrative cultures, bureaucratic functions, personnel skill levels and organizational structures of development bureaucracies. Analysing applications are less compatible because they require a level of training and motivation uncommon in development bureaucracies. Analysing applications are further thwarted by constraints in the supply of relevant information and the lack of demand for analysis by decision-makers. A four-cell matrix is developed which explains these constraints. The article concludes with several recommendations for encouraging microcomputer-based analysis, but cautions that processing applications will continue to dominate for the foreseeable future.  相似文献

The failure of forestry to contribute to poverty reduction in Central America is due to public policies which inhibit its profitability. Absence of public regulation of harvesting and competing subsidies to agriculture keep forestry stumpage prices artificially low. This encourages destruction of the forest resource, which damages both the environment and the potential to reduce poverty. A comparison of Costa Rica and Honduras reveals two dissimilar approaches toward forest policy. While Costa Rica attempts to raise producer and grower stumpage prices by tax credits, soft loans and differential species fees, Honduras enforces price ceilings and uses centralized authority to control forest production and export. Both countries exhibit weaknesses in the management control cycle of programming, budgeting, implementing and evaluating their forest policies. Yet the Costa Rican approach has increased stumpage prices already, which bodes well for their forest sector. By contrast, the major beneficiary of Honduran forest policy has been COHDEFOR, the state enterprise responsible for forestry management, controlling production, and running its national system of agroforestry cooperatives. Despite greater public authority and resources than the Costa Rican forest service (DGF), the Honduran forest policy is not likely to increase producer profitability or reduce poverty in the near future.  相似文献

Provincial governments in the Netherlands have only one general tax at their disposal. However, it has become an insufficient source of revenue for this level of government in the Dutch system. To increase the revenue raising capacity of the provincial governments, thirteen broad-based general tax proposals not used at the local level were examined. The objective was to find a fair and equitable tax that could easily be collected and would result in fl. 200 million in additional revenue for the provincial governments.  相似文献

New York State experimented with replacing their litigation-oriented system for achieving toxic dump site cleanup with one promising to lower transaction costs through alternative dispute resolution. Our analysis of outcomes is informed by three generations of implementation work focusing on (1) the motivations and incentives shaping individual behavior, (2) the larger organizational and political factors associated with variation across cases, and (3) the generic properties of policy implements. This mosaic approach to explanation produces, we believe, a more lifelike picture of use to policy makers for understanding the dynamic and interrelated nature of their choices.  相似文献

The process is not the problem, the problem is the problem. Rudolph Penner (1984). …We argue the superiority of the outcome from the process, not of the process from the outcome. The constancy of the economist's objection to this conclusion when applied to governmental rather than market decisions simply often reflects the fact that, while some economists are not disturbed that consumer preferences lead to allocation policies other than best respond to their own tastes, when political preferences lead to governmental policies not consistent with his informed and considered preferences, they are tempted to attribute irrationality to government.  相似文献
