Macroeconomic Research Roundup - Economic Effects of Natural Disasters


Natural disasters highlight the hidden cost of economic inequality: deaths from flooding
Over 95 percent of the deaths from large floods have occurred in developing countries over the past 25 years. And compared to other natural disasters, the frequency of floods is increasing. The socioeconomic determinants of flood-linked mortality gathered from over 2,000 flood events in 108 countries show that increased income reduces the frequency of floods and associated mortality, while increases in the magnitude of floods and mortality is associated with higher income inequality.

climateHow Do Governments Respond After Catastrophes? Natural-Disaster Shocks and the Fiscal Stance
Estimates of the impact of geological, climatic, and other types of natural disasters on government expenditures and revenues suggest that, on average, budget deficits increase only after climatic disasters, but for lower-middle-income countries, the increase in deficits is widespread across all events.

When do governments require earthquake resilient construction? 
Mortality is higher at any level of quake propensity when governments have fewer incentives to provide public goods.

The Wrath of God: Macroeconomic Costs of Natural Disasters
The process of global climate change has been associated with an increase in the frequency of climatic disasters. Yet, there is still little systematic evidence on the macroeconomic costs of these episodes.

 The Growth Aftermath of Natural Disasters
Tracing the yearly response of gross domestic product growth - both aggregated and disaggregated into its agricultural and non-agricultural components - this paper provides a description of the macroeconomnic aftermath of four types of natural disasters - droughts, floods, earthquakes, and storms.

Natural Disasters and Growth – Going beyond the Averages
The effect of natural disasters on economic growth remains unclear, with some studies reporting negative, and others indicating no, or even positive effects. These seemingly contradictory findings can be reconciled by exploring the effects of natural disasters on growth separately by disaster and economic sector.
