The PSD Blog

This page in:

The Private Sector Development Blog (PSD Blog) gathers together news, resources and ideas about the role of private enterprise in fighting poverty. The blog is informal and represents the quirks and opinions of the bloggers, not the World Bank Group. Please contact us if you have any questions.

Our objective

  • To provide intelligent comment on private sector development issues in the news.
  • To highlight new Web sites, articles and books that development practitioners might find useful.
  • To provide a link between the detailed resources on the World Bank Group’s Rapid Response Web site, and the ever changing world of the blogosphere.

Our hosts

The PSD Blog is maintained by the World Bank Group’s Rapid Response knowledge service, which specializes in policy advice on business environment reform and privatization policy in developing countries. Rapid Response is a joint knowledge initiative of the World Bank and International Finance Corporation (IFC). Information on the mission and products offered by Rapid Response is available online.


All of the PSD Blog authors are members of the World Bank Group. Their posts are their own, and do not necessarily reflect the views and opinions of the World Bank Group, its Board of Directors or the governments they represent. For more information, please see our content policy above.

David Lawrence has worked with IFC since 1996, when he was sent to a small Ukrainian town to set up a small business advisory center. Since then, Dave has focused on post-conflict and post-disaster posts, ideally where water, heat, and electricity are in short supply. In the 1990s he worked in Armenia, Georgia, and Russia, and more recently in the Tsunami-ravaged province on Aceh, Indonesia.

Prior to joining the World Bank Group, he worked at the United Nations University in Yokohama, Japan, and was Knowledge Manager for WWF International. Apart from obscure technologies and pandas, Giulio's interests include Slavic philology and kitsch paraphernalia (you know, snowdomes and the lot) - which combined make him the last person you'd want to be stuck in a lift with.
