Some Economic Science Of Hurricanes

As Hurricane Florence slams into the southeastern United States, hither are a few posts from the past times on the economic science of hurricanes in addition to other natural disasters.

"Economics in addition to Natural Disasters" (November 2, 2012)

This spider web log was written as Hurricane Sandy hitting the US inwards 2012. Among a number of other articles, inwards this spider web log I advert how David Stromberg grade out the economical arguments nigh natural disasters inwards "Natural Disasters, Economic Development, in addition to Humanitarian Aid," appearing inwards the Summer 2007 number of my ain Journal of Economic Perspectives. Stromberg described how the basic framework for economical analysis of natural disasters emerged from correspondence betwixt Voltaire in addition to Rousseau inwards 1755 (footnotes in addition to citations omitted):

"[I]n 1755 an earthquake devastated Lisbon, which was in addition to so Europe’s fourth-largest city. At the showtime quake, fissures v meters broad appeared inwards the metropolis center. The waves of the subsequent seismic sea wave engulfed the harbor in addition to downtown. Fires raged for days inwards areas unaffected past times the tsunami. An estimated 60,000 people were killed, out of a Lisbon population of 275,000. In a missive of the alphabet to Voltaire dated August 18, 1756, Jean-Jacques Rousseau notes that piece the earthquake was an human activeness of nature, previous acts of men, similar housing construction in addition to urban residence patterns, grade the phase for the high expiry toll. Rousseau wrote: “Without departing from your dependent area of Lisbon, admit, for example, that nature did non build 20 grand houses of vi to 7 stories there, in addition to that if the inhabitants of this neat metropolis had been to a greater extent than every bit spread out in addition to to a greater extent than lightly lodged, the harm would convey been much less in addition to maybe of no account.”
"Following Rousseau’s draw of thought, disaster guide a opportunity analysts distinguish iii factors contributing to a disaster: the triggering natural peril lawsuit (such as the earthquake striking inwards the Atlantic Ocean exterior Portugal); the population exposed to the lawsuit (such as the 275,000 citizens of Lisbon); in addition to the vulnerability of that population (higher for the people inwards seven-story buildings)."

"Natural Disasters: Insurance Costs vs. Deaths" (April 16, 2015)

This spider web log send service looked at the lists of the most destructive natural disasters that are published regularly past times Swiss Re.  I discussed why it is that the disasters alongside the greatest losses to belongings are  oft unlike than the disasters alongside the greatest loss of life.  I wrote:

[T]he effects of a given natural disaster on people in addition to belongings volition depend to a substantial extent on what happens earlier in addition to later on the event. Are most of the people living inwards structures that comply alongside an appropriate edifice code? Have civil engineers idea nigh issues similar alluvion protection? Is in that location an early on alert organisation so that people convey as much advance alert of the disaster as possible? How resilient is the infrastucture for electricity, communications, in addition to shipping inwards the confront of the disaster? Was in that location an advance conception earlier the disaster on how back upward services would live mobilized?

In countries alongside high levels of per capita income, many of these investments are already inwards place, in addition to so natural disasters convey the highest costs inwards terms of property, but relatively lower costs inwards terms of life. In countries alongside depression levels of per capita income, these investments inwards wellness in addition to security are oft non inwards place, in addition to much of the belongings that is inwards house is uninsured. Thus, a 7.0 earthquake hits Republic of Haiti inwards 2010, in addition to 225,000 die. Influenza A virus subtype H5N1 9.0 earthquake/tsunami combination hits Nippon inwards 2011--and remember, earthquakes are measured on a base-10 exponential scale, so a 9.0 earthquake has 100 times the shaking might of a 7.0 quake--and less than one-tenth as many people choke as inwards Haiti.

For example, inwards the  the most recent version, run across pp. 48-49 inwards this 2018 report, the most costly natural disaster from 1970-2017 inwards terms of insured losses was Hurricane Katrina inwards 2005, alongside $82 billion inwards losses. But biggest natural disaster over that fourth dimension inwards terms of lives lost was 300,000 dead from storms in addition to flooding inwards People's Republic of Bangladesh inwards 1970. The 1,836 lives lost inwards Katrina don't brand the top-40 listing of most lives lost inwards a natural disaster from 1970-2017.

"The New Orleans Economy Since Katrina" (October 25, 2013)

In describing the aftermath of Hurricane Katrina on New Orleans, I wrote:

"According to U.S. Census Bureau estimates, inwards the July 2005 the population of the New Orleans-Metairie-Kenner metropolitan surface area was surface area at a shade over 1.3 million, essentially unchanged since 2000. By the July 2006 count, dropped to 978,000. The population has rebuilt piece of cake since then, upward to nearly 1.2 i grand one thousand past times July 2009, but remains below the pre-storm level. What nigh the economic scheme of New Orleans? As I'll endeavor to explain, it's a story alongside twists in addition to turns, but maybe without whatever clear policy implication."

One of the sources I mentioned inwards the spider web log quotes Michael Hecht, president of the largest economical evolution means inwards the region, to this effect: “New Orleans was similar a morbidly fat individual who finally had a pump grade on that was rigid plenty to scare them, but non rigid plenty to kill them ... Katrina grade bare that this was a metropolis in addition to a region that had been inwards slow, decadent decline, in all likelihood since the ’60s ...”

I likewise advert an insight nigh natural disasters in addition to housing markets from Jacob Vigdor inwards "The Economic Aftermath of Hurricane Katrina,"which appeared inwards the Fall 2008 number of the Journal of Economic Perspectives. I wrote:

When a metropolis is declining, low-quality housing tin hand the axe locomote quite inexpensive. The resultant is that those alongside depression incomes notice it difficult to exit the city, because although their prospects for earning income aren't good, their damage of housing is low, in addition to moving to another surface area alongside a higher damage of housing seems similar a high-risk choice. But Hurricane Katrina blasted the New Orleans housing stock. Vigdor wrote: `The 2000 Census counted only over 215,000 housing units inwards the metropolis of New Orleans. By 2006, the estimated number of units had declined to 106,000, of which to a greater extent than than 32,000 were vacant. Although these vacant units appeared intact from the exterior, most of them undoubtedly required significant interior rehabilitation prior to occupation. Hurricane Katrina thence rendered two-thirds of the city’s housing stock uninhabitable, at to the lowest degree inwards the brusque term.' To live sure, a substantial total of this housing stock was eventually refurbished. But about of the cycle of low-income people living inwards low-cost housing was diminished, partly because a number of those low-income people ended upward relocated inwards other cities, in addition to partly because much of the refurbished housing was no longer as cheap as it had previously been.
