Aid fragmentation corruption risks are clearer in a new study that links crowded donor activity to higher administrative corruption in developing countries. Sungkyunkwan University said the research uses local-level evidence from Afghanistan to show how aid can lose effectiveness when many agencies operate in the same place without clear accountability.
The study was led by Travers B. Child of the SKK Graduate School of Business at Sungkyunkwan University, with Austin L. Wright of the University of Chicago and Yun Xiao of the University of Gothenburg. Sungkyunkwan University said the team is the first to use micro-level data to demonstrate the relationship between aid fragmentation and administrative corruption.
What is aid fragmentation?
Aid fragmentation is the overlap that occurs when many international aid agencies and organizations run projects in the same developing-country region at the same time. The concern, according to Sungkyunkwan University, is that multiple projects and donors can weaken coordination, blur responsibility and make oversight harder.
The researchers analyzed more than 30,000 aid projects across 330 districts in Afghanistan and combined that information with large household survey data collected by NATO. The study found that when one aid agency supplied focused support, local corruption fell significantly, according to Sungkyunkwan University.
The pattern changed when many agencies worked in the same area. The university said weaker mutual monitoring and spread-out responsibility allowed aid itself to become a route for corruption.
How does aid fragmentation affect corruption?
The study found that the effect depends on both the amount of aid and the kind of project. Sungkyunkwan University said several agencies working together could have a positive effect when aid levels were moderate, because they brought different ideas and practices to the same area.
At very high funding levels, however, fragmentation had a stronger negative effect. The researchers found that corruption rose sharply when large volumes of aid entered regions where many agencies were active, according to the university.
The type of aid also mattered. The team found that corruption appeared more often in visible physical infrastructure projects, including roads, bridges and supply delivery, than in nonphysical services such as education or welfare.
The findings address a long-running concern in international development: whether overlapping donors reduce the value of aid. Sungkyunkwan University said earlier debate had lacked concrete statistical evidence showing how fragmentation connects to corruption at the local level.
The research, titled “Aid Fragmentation and Corruption,” was published in the May 2026 issue of the Review of Economics and Statistics. The publication lists the DOI as 10.1162/rest_a_01458.
