Philadelphia, PA — In the wake of natural disasters, survivors’ losses of education and lifetime earnings may be comparable to the cost of property damage, according to a new study in Nature Human Behaviour by Dr. R. Jisung Park, an assistant professor at Penn’s School of Social Policy & Practice (SP2) with a secondary appointment at the Wharton School, and coauthors Isaac M. Opper of RAND Corporation and Lucas Husted of Columbia University.

“In this paper, we compile what is to our knowledge the most comprehensive dataset assembled to date to assess the human capital consequences of natural disasters,” write Dr. Park and colleagues, who note the link between climate change and natural disasters.

By combining data about national disaster declarations, local property damage, standardized achievement, and post-secondary enrollment in the United States from 2008 to 2018, the authors quantify how natural disasters reduce learning, years of schooling, and ultimately the lifetime earnings of the people they affect:

“These numbers should be viewed as indicative of the impact that disasters have on human capital, rather than definitive estimates of their effects,” the authors write.

The findings bolster existing evidence that the natural environment is a significant factor contributing to economic inequality. They also point to the need to develop policy approaches that would help societies to address the human cost of natural disasters, such as educational assistance programs.

Park is an environmental and labor economist interested broadly in how environmental factors shape economic opportunity. Prior to joining Penn, he was a member of the faculty at UCLA, and a post-doctoral fellow at Harvard. Park’s research combines data, quasi-experimental methods, and economic analysis to better understand the implications of environmental change for human flourishing, and how effective policy responses may be designed.
