Pré-publication, Document de travail: Using a change in the rules of EU food aid policy in 1996, I investigate how donor countries react to EU's food aid allocation. On average if the EU stops allocating food aid to a small country, this reduces by 1.4 the average number of other donors. Donors reactions are heterogeneous. Next, I develop a simple framework in which donors react to EU's action either indirectly because it changes the recipient's needs or directly because they are motivated by comparing their allocation with the one of EU. I derive a donor typology from this framework. Large donors and Nordic countries are motivated by direct comparison with the EU allocation while the WFP is driven by recipient-related motives.
