 As an alternative, Dollar proposes that aid be funneled more towards countries with "good" policy and less than optimal amounts of aid for their massive amounts of poverty.With respect to "optimal amounts" Dollar calculated the marginal productivity of each additional dollar of foreign aid for the countries sampled, and saw that some countries had very high rates of marginal productivity (each dollar went further), while others [with particularly high amounts of aid, and lower levels of poverty] had low [and sometimes negative] levels of marginal productivity.In terms of economic efficiency, aid funding would be best allocated towards countries whose marginal productivities per dollar were highest, and away from those countries who had low to negative marginal productivities.
