Scholars studying foreign assistance differ over whether multilateral aid is preferable to bilateral aid for promoting development, but nearly all build their cases primarily on highly aggregated cross-national time-series data. We investigate this topic experimentally from the perspective of those whom the foreign aid directly affects: recipient citizens and elites. We thus report results of a survey experiment with behavioral outcomes on more than 3000 Ugandan citizens and over 300 members of Uganda’s Parliament. In spite of a large literature suggesting differences, the findings generally reveal few substantive differences in citizens’ and elites’ preferences and behavior toward the two types of aid. While no strong pattern of differences emerges, limited evidence suggests that the public evinces greater trust in multilateral institutions, and both masses and elites feel that multilateral aid is more transparent. Overall, these null results inform an ever-expanding literature, which is increasingly articulating distinctions between multilateral and bilateral aid. At least in the minds of the recipients, however, multilateral and bilateral aid may not in fact be all that different. This accords with the literature noting the strong overlap in aid organizations and bemoaning the fact that they do not specialize more. Our results raise the question about why have both multilateral and bilateral aid donors if they in effect do the same thing.  相似文献

The Mississippi River has claimed many lives over the last several decades. A better understanding of the universal dynamics of its fluvial system can help direct the production of a predictive model regarding the transportation of human remains in the river. The model may then be applied to situations where the location and the identification of water victims are necessarily part of the recovery process. Results from the preliminary phase of a longitudinal project involving the transport of human remains in the Mississippi River are presented and represent the analyses of 233 case files of river victims. A provisional model for fluvial transport of human remains in the Mississippi River is proposed and examined. This model indicates that time in the river and distance a body travels are related. Such a model may assist in pinpointing entry location for unidentified human remains found in the river or on its banks. Further, it has the potential to provide local and regional law enforcement agencies, the United States Coast Guard, and other search and rescue organizations with primary search areas when someone is missing in the river. Other results from this study indicate that a relationship exists between the side of the river where victims enter the water and the side of the river where the remains are recovered. Finally, relationships are established between the length of time before recovery of the remains and state of preservation exhibited by those remains. A secondary benefit from this study is a database of river victims that can be used by a variety of different agencies.  相似文献
