Climate, ecosystem resilience, and the slave trade

James Fenske, Namrata Kala, 11 June 2013

The slave trade continues to shape modern Africa. This column analyzes environmental shocks to the supply side of the trans-Atlantic slave trade and their long-term effects. During warm periods, African ports exported fewer slaves because lower agricultural productivity raised slavers' costs. These temperature fluctuations had long-run impacts, and ports that experienced a warmer period during the decades when the slave trade was most active appear more developed today.

Doing Business – less icing, more cake!

Thorsten Beck, 6 June 2013

The World Bank’s ‘Doing Business’ data collection project is under threat from large nations who score poorly, especially China. This column argues that although there are problems with country rankings, the underlying data is very valuable for empirical researchers. The Doing Business project should continue quantifying different dimensions of the business environment, but reduce its focus on country rankings.

Sebnem Kalemli-Ozcan, Christian Fons-Rosen, Bent E. Sørensen, Carolina Villegas-Sanchez, Vadym Volosovych, 4 June 2013

During the decades of globalisation, flows of foreign direct investment have surged in parallel with extensive policy momentum. This column examines whether the net aggregate gain from FDI is positive using a large panel of firms from 30 European countries. It turns out that even very large increases in FDI are not important for country-level productivity growth.

Preparing to export

Danielken Molina, Marc Muendler, 27 May 2013

Exporting is essential for economic development. But can firms move from local sales to export sales? How do firms prepare for exporting? This column presents new research showing that worker mobility is an important mechanism by which exporter knowledge spreads through the economy.

Effective aid in conflict zones

Eli Berman, Joe Felter, Jacob N. Shapiro, Erin Troland, 26 May 2013

Can foreign aid help countries emerge from civil war? This paper presents new research that suggests that injecting lots of money into conflict zones may in fact encourage corruption and violence. The aid community should focus on what it can do well: working closely with communities to target small-scale, modest improvements that can be implemented in conflict zones. If accompanied by a gradual improvement in the quality of governance, current aid recipients can aspire to a long-run improvement in both security and prosperity.
