Large-scale infrastructure projects are a vital part of the World Bank's

development agenda, but the World Bank and host countries alike have

placed little emphasis on combating corruption attached to these projects.

Investigation of ongoing corruption and punishment of offenders is an

important end goal in itself, and can be an important deterrent to future

corruption. The World Bank and host countries face challenges in

properly pursuing investigation and punishment, but the results

certainly are worth the effort. This Note explores the importance of

investigating and punishing corporate corruption on World Bank-funded

large-scale infrastructure projects, and presents practical suggestions as

to how investigation and punishment processes might be made more

effective. Specifically, host countries and the World Bank should utilize a

"trigger" mechanism, by which investigations by one party automatically

trigger investigations by the other, in order to increase accountability.

Other factors - including the willingness of third party states to assist in

these efforts - also influence the outcome, but the triggering mechanism

may be an important step forward. The outcome of the Lesotho

Highlands Water Project corruption investigations provides a useful

illustration of how such a cooperative triggering mechanism might work.
