What are the benefits of an international approach to foreign aid? Thank you very much!
There is strength in numbers, and we tend to encourage each other to bring out our best efforts. If the US, for example, pledges $200 million for Haiti Earthquake Relief, then European countries are going to feel obliged to pledge as well. So the initial public donation in an international effort stimulates other giving. A country that might only give $1 million in aid would be less likely to do so if it wasn't part of a larger effort that was more likely to do some good.
Each country has a specific amount of means to donate and methods to get them there. Sharing logistical and technical support can greatly increase a chance of an aid mission's success.
When you use this term, I assume that you are talking about having lots of countries get together to give foreign aid (rather than having individual countries give aid on their own).
If so, the major benefit is that it would allow the country getting the aid to be less dependent on any one nation. If individual countries give foreign aid, a country that gets most of its aid from one rich country would pretty much have to do what that rich country said.
In addition, aid might be given out more based on need and not based on what was good for the donor country.
