Unfortunately, not all of my projects have been successful, but they may still be of interest if you're exploring similar topics. If so, feel free to reach out—I’d be happy to share more details about what I did and why I decided to leave them as permanent working papers.
Sustainability Performance and Stock Returns in Brazil
Summary: We use ten years of data, from 2005-2016, to estimate the effect on stock returns of being included or excluded from the sustainability index (ISE) of São Paulo Stock Exchange (BM&F Bovespa). We also test for the effect of, once included in the ISE, a company releasing publicly the answers to the questionnaires used to define the components of the index. We employ an event study. We do not find robust evidence of a positive impact neither for being included in the index, nor for being excluded from it. Also, the release of questionnaires by the components of the ISE seems not to present any major effect too, though we find some evidence of a delayed significant effect. Our results suggest that sustainability performance understood in a broader sense as in the ISE does not seem to have an effect on the financial performance of Brazilian firms.
Geological Disasters and Growth: Evidence from Volcanic Eruptions
Summary: I study the GDP growth impacts of geological disasters by focusing on volcanic eruptions. Despite their ubiquity, geological disasters, in particular volcanic eruptions, have not been as extensively studied as climatic disasters in the economics literature. Results are mostly null across different specifications. I use more granular data than previous studies in the growth impacts of natural disasters literature.
