Grand Corruption in Utilities, co-authored with Tina Soreide, was issued as a working paper in December 2008. The paper discusses mechanisms of grand corruption in private sector utility provision in developing countries. The paper focuses on decisions made at the government level involving private sector management, ownership, and provision of utility services. Corruption at that level may influence the pace and nature of private sector involvement and competition in utilities, as well as the level and form of investments, subsidies, and prices. On the basis of a literature review and interviews with firms and regulating authorities in two countries, Tanzania and the Philippines, this paper discusses the levels and determinants of grand corruption in utilities. The paper concludes by discussing a research program to extend this knowledge through a cross-country survey instrument.
