“You are moving from a continent that, 20 years ago, had a small and very wealthy top and a broad base of poverty with no middle market, to one that is developing one of the largest mass markets in the world – Africa will be the equivalent of China.”
I have been somewhat skeptical about the application of impact evaluations to justice reform activities but I’m coming around to their utility for a limited – yet important – set of questions. The basic method behind impact evaluations – establishing a counterfactual in order to attribute net impact – is fairly new to justice so I thought I’d set out some ideas that might be worth considering in developing this nascent field.
Poverty has been a concern in societies even before the beginning of recorded history. In the past three decades extreme poverty in the world has decreased significantly. More than half of population in the developing world lived on less than $1.25 a day in 1981. This has dropped to 21% in 2010. More impressively, notwithstanding a 59% increase in population in developing countries, there were 1.2 people living on less than $1.25 a day in 2010, compared with 1.9 billion decades ago. However, the challenge of poverty reduction ahead remains daunting with 1.2 billion still living in extreme poverty. Freeing the world from poverty is perhaps the most important economic goal for the world today. More than a hundred countries are still not able to move away from high poverty traps.

"How can I unpivot or transpose my tabular data so that there's only one record per row?"
I see this question a lot and I thought it was worth a quick Friday blog post.
Data often aren’t quite in the format that you want. We usually provide CSV / XLS access to our data in “pivoted” or “normalized” form so they look like this:
But for a lot analyses and applications, particularly data visualisation tools like D3, ggplot2, Tableau, it’s more convenient to have your data “unpivoted” or “denormalized” so it looks like this:
Although this is less space efficient, space is cheap, and it means there’s always only one record per row, so you can use simple functions to access and filter data.
Here are three ways to “unpivot” or “denormalize” your data - in effect, to transpose columns to rows and have one complete record per row.
The growth of China and India and their financial sectors are hard to ignore. In a recent working paper, Tatiana Didier and I study the extent to which firms in these countries use capital markets to obtain financing and grow.
The World Bank and the Nigerian Bureau of Statistics (NBS) have recently completed an in-depth analysis of Nigeria’s last set of household survey statistics, which were compiled in 2010 but until recently not fully understood.
The results suggest strangely mixed conclusions. In certain ways, poverty trends in Nigeria over the past decade were better than has been widely reported, where a story of increasing poverty has been the consensus. And yet poverty is stubbornly high, disappointingly so given growth rates.
Three facts stand out.
The greatest development challenge facing Sub-Saharan Africa today is lifting 400 million of its people out of extreme poverty. The continent has abundant land and mineral resources to meet the challenge, but only if land governance can be improved. A new study, Securing Africa’s Land for Shared Prosperity, offers a ten-point program to improve land governance by accelerating policy reforms and boosting investments at a cost of US $4.5 billion over 10 years.
There is much to be discouraged by in Transparency International’s recently-released 2013 Global Corruption Barometer, the biennial global survey that gauges popular perceptions about the extent of corruption in public life. More than half of 114,000 people in 107 countries polled for the 2013 survey believe that corruption has increased over the last couple of years. And 27 per cent of the respondents reported having paid a bribe when accessing public services and institutions, an increase from the 10 per cent that reported similar incidents in the 2009, 2007, and 2005 surveys.
The intransigence of the challenge might not be news to international agencies, but it is certainly a cause for introspection. For a few decades now, aid agencies (including the Bank following the 1997 Cancer of Corruption speech by then President Wolfensohn), have aimed to help stem corruption through regulatory tools such as codes of conduct, access to information laws, standards for procurement and public financial management, conflict of interest and asset disclosure regulations, and by establishing oversight institutions such as anti-corruption agencies, audit institutions, and parliamentary oversight committees. More recently, in response to a recognition that such technical fixes are only half a solution, the “demand side” of governance has received much attention, and there are several examples of successful programs, as chronicled, for instance, by retired Bank staffer, Pierre Landell-Mills, in a recent compendium.
