Three essays on the economic impact of natural disasters

Summary of Thesis

Natural disasters have particularly devastating consequences in developing countries where people are highly vulnerable and institutions remain inefficient. Nevertheless, their impacts on households’ well-being and the role of public authorities are, yet, not fully understood. In addition, while most studies focus on climatic risk, geological disasters, and volcanic eruptions in particular, are clearly understudied. However, despite representing a marginal share of natural disasters at the global level, volcanic eruptions are a major threat in some countries, such as Indonesia or Ecuador. The present dissertation tries to contribute to the literature by investigating the long-term effect of volcanic hazard on farmers’ capital accumulation, the impact of an eruption on social capital, as well as the potential mitigating role of public authorities on migration decisions.
