During disasters, many researchers highlight the efficiency of the various information techniques that are used for emergency response. However, only a few information systems consider on-site and off-site information requirements synchronously. The results achieved by the emergency responders...

Each year natural disasters affect about 200 million people and cause about $50 billion in damage. This paper compares the incidence of natural disasters across countries along several dimensions and finds that the relative costs tend to be far higher in developing countries than in advanced...

Natural earthquake disasters are unprecedented incidents which take many lives as a consequence and cause major damages to lifeline infrastructures. Various agencies in a country are responsible for reducing such adverse impacts within specific budgets. These responsibilities range from before...

The problem of optimally deploying urban search and rescue (USAR) teams to disaster sites in post-disaster circumstances is formulated as a multistage stochastic program (MSP). A portion of sites requiring assistance arrive dynamically over the decision horizon and key problem characteristics...

The fiscal impact of these policies will be significant, but donor support, improved revenue, and budget reallocations will contain domestic financing. The authorities have introduced several policies in response to the disasters. IMF staff supports the authorities’ request for a purchase...

Local and regional procurement (LRP) of food aid is often claimed to lead to quicker and more cost-effective response. We generate timeliness and cost-effectiveness estimates by comparing US-funded LRP activities in nine countries against in-kind, transoceanic food aid shipments from the US to...
