States to western Europe under the Marshall Plan. Academic theories Since the 1960s, improving the efficiency of foreign aid has been a common topic of academic research. There is debate on whether foreign aid is efficacious, but for the purposes of this article we will ignore that. Given that schema, a common debate is over which factors influence the overall economic efficiency of foreign aid. Indeed, there is debate about whether aid impact should be measured empirically at all, but again, we will limit our scope to increasing the economic efficiency. At the forefront of the aid debate has been the conflict between professor William Easterly of New York University and his ideological opposite, Jeffrey Sachs, from Columbia University. Easterly advocates the "searcher's" approach, while Sachs advocates a more top down, broad planned approach. We will discuss both of these at length. "Searchers Approach" William Easterly offers a nontraditional, and somewhat controversial "searching" approach to dealing with poverty, as opposed to the "planned" approach in his famous critique of the more traditional Owen/Sachs, The White Man's Burden. Traditional poverty reduction, Easterly claims is based on the idea that we know what is best for impoverished countries. He claims that they know what is best. Having a top down "master plan," he claims, is inefficient. His alternative, called the "Searchers" approach, uses a bottom up strategy. That is, this approach starts by surveying the poor in the countries in question, and then tries to directly aid individuals, rather than governments. Local markets are a key incentive structure. The primary example is of mosquito nets in Malawi. In this example, an NGO sells mosquito nets to rich Malawians, and uses the profits to subsidize cheap sales to the impoverished. Hospital nurses are used as middle-women, profiting a few cents on every net sold to a patient. This incentive structure has seen the usage of nets in Malawi spike over 40% in less than seven years. One of the central tenets in Easterly's approach is a more bottom up philosophy of aid. This applies not only to the identification of problems, but to the actual distribution of capital to the areas in need. In effect, Easterly would have countries go to the area which needed aid, collect information about the problem, find out what the population wanted, and then work from there. In keeping with this, funds would also be distributed from the
