In my comments on "Poverty, health and health psychology: a critical perspective", by Kerry Chamberlain I discussed three main points. First, I talked about the concerns by development economists related to the establishment of a causal link between health and poverty, highlighting how is empirically challenging testing a causal relationship between these two variables. I then described the wide used of the Randomized Control Trials, an important tool now often use to rigorously test the causal effect of an intervention on different outcomes and provide an example of an intervention in Mexico able to identify the causal association between poverty alleviation and health. Second, I reported the theory behind the design of programs aimed at reducing poverty by describing supply and demand side interventions. Finally, I described the approach and the methodology used by economists to evaluate the efficacy of poverty alleviation interventions, highlighting the need of combining quantitative and qualitative analysis.
