Dialing for Data: The Story of a High Frequency Phone Survey in Liberia

Kristen Himelein's picture

Yesterday the World Bank released their first report on the socioeconomic impacts of Ebola that was based on household data.  The report provides a number of new insights into the crisis in Liberia, showing, for example, an unexpected resiliency in agriculture, and broader economic impacts than previously believed in areas outside the main zones of infection.  As widely reported, prices for staple crops (such as rice) have jumped well above seasonal increases, but additionally we find an important income effect.  We also find the highest prices in the remote southeast of the country, an area that has been relatively unaffected by the disease. The link to the full report can be found here.

Almost 80 percent of the growth in remittances to developing countries over the past 20 years is an illusion

Remittances sent by migrant workers to developing countries have soared in the past two decades. According to the World Development Indicators, workers’ remittances to developing countries were just US$47 billion in 1980 (in constant 2011 dollars). After barely rising by 1990 ($49 billion), they doubled by 2000 ($102 billion), and from there, tripled by 2010 ($321 billion).

How stable are time preferences? Mixed evidence from two new studies

The discount rate used by individuals to trade off utility in the future against utility today is a fundamental parameter of decision theory. It is typically elicited in surveys by asking individuals to make choices between receiving an amount today, and a different amount at some point in the future. There are lots of key design issues involved in doing this (e.g.

Three new papers on measuring stuff that is difficult to measure

There are a number of things we would like to measure for which a direct question may be refused or met with an inaccurate answer. Three new papers demonstrate some of the methods that can be used to help overcome these problems.

Measuring International Mobility Through Where People Log In to Commonly Used Websites

David McKenzie's picture

International mobility of people is measured much less accurately than that of goods or finances. The most common sources of global data are from national censuses, which occur only every 10 years (and take years more to come out). Specialized surveys in some countries allow more frequent measurement of some flows, but such data are still relatively rare, and poorly suited to studying short-term migration movements.

Economists have experiments figured out. What’s next? (Hint: It’s Measurement)

“Everybody lies.” This is the famous refrain of Dr. Gregory House that is repeated in almost every episode of the TV show House. But, we need not need to take our guidance from an eccentric TV character: academics have been heard stating similar sentiments.

Power to the people? Taking a look at community driven reconstruction in the DRC

Given the Bank's recent release of a report on community driven development and a recent New York Times article about the intractability of peace in the Democratic Republic of the Congo, I thought it would be worth looking at a recent

Let’s not overstate the achievements of China and India – here are the real growth stars

When we talk about growth, we typically focus on growth rates, and so if we were to look at which countries had the greatest percentage increase in GDP per capita over the last decade (at constant international prices according to the World Development Indicators), we would get a table like this:
