The quality of economic statistics in Africa has been likened to a statistical tragedy. Currently many statistical systems in Africa are being updated. This report from the statistical offices in Nigeria, Liberia and Zimbabwe documents that base year, data and methods used to generate GDP estimates currently date from 1990, 1992 and 1994. There is a growing need for macroeconomic statistics, but a

Coordinating aid distribution to the poorest countries requires identifying which countries are poor. In practice this has meant sorting countries into developmental cohorts on the basis of macroeconomic data, with countries in poorer cohorts gaining access to more and more concessional aid programs. To the extent that governments can influence their macroeconomic data, some, especially those in a

In this article, we experimentally demonstrate a way of controlling the group velocity of an optical pulse by using a combination of spectral hole burning, the slow-light effect, and the linear Stark effect in a rare-earth-ion-doped crystal. The group velocity can be changed continuously by a factor of 20 without significant pulse distortion or absorption of the pulse energy. With a similar techni

One of the most urgent challenges in African economic development is to devise a strategy for improving statistical capacity. Reliable statistics, including estimates of economic growth rates and per-capita income, are basic to the operation of governments in developing countries and vital to nongovernmental organizations and other entities that provide financial aid to them. Rich countries and in

How do we measure African economic performance? This volume studies how growth is measured in Botswana, Kenya, Tanzania and Zambia and challenges commonly held beliefs of African economic performance. The volume offers a reconsideration of economic growth in Africa in three respects. First, it shows that the focus has been on average economic growth and that there has been no failure of economic g

Not so long ago, Africa was being described as the ‘Hopeless Continent’. Recently, though, talk has turned to ‘Africa Rising’, with enthusiastic voices exclaiming the potential for economic growth across many of its countries. What, then, is the truth behind Africa’s growth, or lack of it?In this provocative book, Morten Jerven fundamentally reframes the debate, challenging mainstream accounts of

The chief economist for the World Bank's Africa region, Shanta Devarajan, delivered a devastating assessment of the capacity of African states to measure development in his 2013 article "Africa's Statistical Tragedy". Is there a "statistical tragedy" unfolding in Africa now? If so, it becomes important to examine the roots of the problem as far as the provision of statistics in poor economies is c

What do we know about economic development in Africa? The answer is that we know much less than we would like to think. This collection assesses the knowledge problem present in statistics on poverty, agriculture, labour, education, health, and economic growth. While diverse in origin, the contributors to this book are unified in two conclusions: the quality and quantity of data needs to be improv

More than two decades of Palestinian state-building have produced neither peace nor a state. In fact, the Palestinians are seemingly further away from statehood today than at any point since the state-building process began in the mid-90s, despite the fact that the West Bank’s institutions now perform, according to the UN, the EU, the World Bank and IMF, above the threshold for what is expected of
