Over the last decades, extreme climatic events have significantly affected Central America and specially Guatemala. This paper tests if Social Aid Programs in Guatemala reduced the negative impacts of Tropical Storm Stan from 2005. We estimate the effect of the storm on whether a household reports being poorer In 2006 relative to 2000. We compare these results between those that receive and did not receive social aid. We applied matching techniques to control for differences in explanatory observable characteristics of households. First, we find that households that were affected by Stand are significantly more likely to report being poorer. Second a we find that the negative effects of Stand are lower for benefited households than for similar non benefited households. These results were robust for different age groups, for household headed by woman: households headed by individuals with low levels of education, and households in the urban area. However, the results were not robust for households headed by men, by individuals with high levels of educations as well as for those in rural areas.
