Sommario/riassunto

This paper studies the economic costs of hurricanes in the Caribbean by constructing a  novel dataset that combines a detailed record of tropical cyclones’ characteristics with  reported damages. I estimate the relation between hurricane wind speeds and damages in  the Caribbean; finding that the elasticity of damages to GDP ratio with respect to  maximum wind speeds is three in the case of landfalls. The data show that hurricane  damages are considerably underreported, particularly in the 1950s and 1960s, with  average damages potentially being three times as large as the reported average of 1.6  percent of GDP per year. I document and show that hurricanes that do not make landfall  also have considerable negative impacts on the Caribbean economies. Finally, I estimate  that the average annual hurricane damages in the Caribbean will increase between 22 and  77 percent by the year 2100, in a global warming scenario of high CO2 concentrations and  high global temperatures.

Sommario/riassunto

Missing Data in Clinical Studies provides a comprehensive account of the problems arising when data from clinical and related studies are incomplete, and presents the reader with approaches to effectively address them. The text provides a critique of conventional and simple methods before moving on to discuss more advanced approaches. The authors focus on practical and modeling concepts, providing an extensive set of case studies to illustrate the problems described. Provides a practical guide to the analysis of clinical trials and related studies with missing data.Examines
