Many developing countries are putting increased pressure on local governments to mobilize resources, especially to meet the recurrent costs of operating and maintaining locally sited capital projects. Local taxes, user charges and voluntary contributions are all possible mechanisms to carry out these efforts. Yet several important issues arise whenever these mobilization instruments are contemplated and evaluated. Several, often competing, objectives must be considered when evaluating fiscal instruments including the ability of the mechanism to raise revenues, its effect on economic efficiency, its equity implications and its administrative feasibility. After discussing each of these objectives, we show how numerous constraints, including those imposed by the political/legal system, administrative structure, the economy and the culture of the country, must be recognized while searching for a workable set of reforms that will mobilize additional resources without doing great harm to the other objectives. The key to these reforms would seem to be incentives or disincentives inherent in the revenue structure. Without recognizing these incentives or attempting to alter them, resource mobilization efforts are likely to go astray. 相似文献

The contemporary political climate is virtually demanding significant intelligence reforms based on what are seen as poor performances in recent crises. Many of these demands will ask for new agencies, more money, and more personnel. Such actions could well worsen the US intelligence process rather than strengthen it. However, now is a propitious time to make certain internal reforms and to find a way for the Intelligence Community to be truly integrated. 相似文献

Using epidemiological techniques for testing disease contagion, it has recently been found that in the wake of a residential
burglary, the risk to nearby homes is temporarily elevated. This paper demonstrates the ubiquity of this phenomenon by analyzing
space–time patterns of burglary in 10 areas, located in five different countries. While the precise patterns vary, for all
areas, houses within 200 m of a burgled home were at an elevated risk of burglary for a period of at least two weeks. For
three of the five countries, differences in these patterns may partly be explained by simple differences in target density.
The findings inform theories of crime concentration and offender targeting strategies, and have implications for crime forecasting
and crime reduction more generally.
