Abstract:

This paper uses year-to-year variation in temperature to estimate the long-term effects of climate change on health outcomes in Mexico. Combining temperature data at the district level and three rounds of nationally representative household surveys, an individual’s health as an adult is matched with the history of heat waves from birth to adulthood. A flexible econometric model is used to identify critical health periods with respect to temperature. It is shown that exposure to higher temperatures early in life has negative consequences on adult height. Most importantly, the effects are concentrated at the times where children experience growth spurts: infancy and adolescence. The robustness of these findings is confirmed when using health outcomes derived from accidents, which are uncorrelated with early exposure to high temperatures.

    This paper attempts to identify the climatic effect on birth outcomes in Brazil and, thus, to predict the potential impact of climate change. Panel data models indicate that excess and lack of rainfall have the most important harmful effects on newborns’ health; temperature stresses and low relative humidity also have effects. The use of climate change forecasts for Brazil suggests a possible incr ... (View publication)

    Using data for all 2,454 municipalities of Mexico for the period 1980-2010, this paper analyzes the relationship between exposure to extreme temperatures and precipitation and death, as well as the relationship between severe weather and agricultural income and crop production in the country. It is found that extreme heat increases mortality, while the health effect of extreme cold is generally tr ... (View publication)

    The general objective of this study is to review the international literature and best practices to develop a methodological framework capable of quantifying the increase in investments necessary for a traditional standard of living in a world subject to climate change. This methodology is then applied to two case studies: Bolivia and Chile. In particular, the document addresses the economics of a ... (View publication)
