To design effective and durable relief programs for refugees and internally displaced people (IDPs), it is essential to understand the nature and context of the challenges the people living in these situations face. That’s why we have recently started to measure consumption and estimate rates of poverty among displaced populations. Through understanding the most acute challenges that vulnerable populations face, relief can be targeted to where support is needed most.
Oxfam number cruncher Deborah Hardoon tries to get her head round something weird – according to the stats, the poorest half of the world is getting poorer even though the incomes of these people are rising.
It has become something of a tradition that in January every year we take a look at the Forbes list of billionaires and the Credit Suisse Global Wealth databook and calculate how many billionaires it takes to have the same amount of wealth as the bottom 50% of the planet. Since we started doing these calculations, we have watched the wealth of the top grow at the same time as the wealth of the bottom 50% has fallen. The data tells us that the bottom 50% have approximately $1 trillion (that’s $1,000 billion) less wealth than they did 5 years ago, whilst the richest 62 have about $0.5 trillion more.
The extremely wealthy are able to accumulate more wealth in a day than a whole factory full of workers could earn in a year. On 21stApril, in a 24 hour period, Carlos Slim made more than $400 million. Thomas Piketty famously points out that the rate of return on capital is higher than the general growth rate, such that capital owners are at a distinct economic advantage.
Meanwhile those 3.6 billion people in the bottom 50% include people in debt, people with nothing and people with a net wealth of up to about $5,000. People with little, no, or negative wealth, especially in developing countries with poor social insurance mechanisms (four out of five people in the bottom 50% live in Africa or Asia – including China and India), will not only find it hard to respond to financial shocks – like a poor harvest or a medical bill, but will also find it much harder to invest in their families’ future. Having little wealth may be concerning, but having less and less wealth year to year is even more worrying.
"Statistics are far from politics-free; indeed, politics is encoded in their genes. This is ultimately a good thing."
- Angus Deaton, a British-American economist. In 2015, he was awarded the Nobel Memorial Prize in Economic Sciences for his analysis of consumption, poverty, and welfare. The Nobel Prize website writes, "To design economic policy that promotes welfare and reduces poverty, we must first understand individual consumption choices. More than anyone else, Angus Deaton has enhanced this understanding. By linking detailed individual choices and aggregate outcomes, his research has helped transform the fields of microeconomics, macroeconomics, and development economics."
The Chinese economy has changed dramatically over the last three decades. While its per-capita income was only a third of that of Sub-Saharan Africa in 1978, it has now reached an upper-middle income status, lifting more than half a billion people out of poverty. The numbers are dramatic: per capita income has doubled for more than a billion people in just 12 years. What was once a primarily rural, agricultural economy has been transformed into an increasingly urban and diversified economic structure, with decentralization and market-based relations rising relative to the traditional government driven command-based economy.
As the Carnival in Brazil kicked off last weekend, Brazilians were ready for a party. They have reasons to celebrate. Despite a lackluster GDP performance in the last two years, unemployment rates remain at record low levels.
Markus’ s post yesterday is the first on what will be one recurring blog theme here- measurement. I’ll continue the trend today with a focus on one of the most fundamental welfare constructs in economics: consumption. Specifically, how might the development researcher accurately measure household consumption through survey?

Food prices have received a lot of attention recently. Understandably, much of the attention is on recent developments and short term prospects. But in this blog post I try to look back at some longer term trends, in order to look further ahead.
Since the early 2000s, food related prices have trended up (Figure 1). The deflator of agricultural value added has risen 8% per year on average since 2000, after falling during the second half of the 1990s. Producer Price Index (PPI) food prices (factory gate) have risen much less because prices of other inputs into the food processing industry have gone up less and rapid productivity growth in food processing has dampened the transmission of higher raw food prices.
