no clear average effect on the speed with which countries develop. Negative side effects of aid can include an unbalanced appreciation of the recipient's currency (known as Dutch Disease), increasing corruption, and adverse political effects such as postponements of necessary economic and democratic reforms. Other econometric studies suggest that development aid effectively reduces poverty in developing countries. Promoting or easing conflict Furthermore, the effect of Aid on conflict intensity and onset have been proved to have different impacts in different countries and situations. For instance, for the case of Colombia Dube and Naidu (2015) showed that Aid from the US seems to have been diverted to paramilitary groups, increasing political violence. Moreover, Nunn and Qian (2014) have found that an increase in U.S. food aid increases conflict intensity; they claim that the main mechanism driving this result is predation of the aid by the rebel groups. In fact, they note that aid can have the unintentional consequence of actually improving rebel groups' ability to continue conflict, as vehicles and communications equipment usually accompany the aid that is stolen. These tools improve the ability of rebel groups to organize and give them assets to trade for arms, possibly increasing the length of the fighting. Finally, Crost, Felter and Johnston (2014) have showed that a development program in the Philippines have had the unintended effect of increasing conflict because of a strategic retaliation from the rebel group, on where they tried to prevent that the development program increases support to the government. Imposition of inappropriate strategies and technologies According to James Ferguson, these issues might be caused by deficient diagnostics of the development agencies. In his book The Anti-Politics Machine, Ferguson uses the example of the Thaba-Tseka project in Lesotho to illustrate how a bad diagnostic on the economic activity of the population and the desire to stay away from local politics, caused a livestock project to fail. According to Martijn Nitzsche, another problem is the way on how development projects are sometimes constructed and how they are maintained by the local population. Often, projects are made with technology that is hard to understand and too difficult to repair, resulting in unavoidable failure over time. Also, in some cases the local population is not very interested in seeing the project to succeed and may revert to disassembling it to retain valuable source materials. Finally, villagers do not always maintain a project as
