A classical production model has been used to define the conditions of relative advantage of different response options and to capture the effect of some contextual variables on such conditions. This type of approach can be quite useful when trying to optimise response strategy through its geographical diversification or adjustment over time. While such analytical approach reflects mainly a static cost-efficiency perspective, it can be sharpened through the partial inclusion of an effectiveness perspective. © 2017 Board of Trustees of the University of IllinoisenAidCash transfersCost-efficiencyFood securityMarket functioningArtículoCC BY 4.0 DEED10.1016/j.qref.2017.02.001
