Ritva, Many thanks.It's very useful to get your perspective on why the Uganda experience was such a success. You make the point of credible enforcement, and "common knowledge", but the other striking feature your comments allude to is the power of your large sample, quantitative evidence on leakage in persuading the government to take action for greater accountability. It seems there is enormous untapped potential of using such large sample statistical methodology, and impact evaluations, in the governance work in the Bank. Doing more such governance interventions IE work in the HD sector has the advantage of measuring impact on actual development results--improved health and education outcomes. Is such governance IE work happening in HD? Is there scope for such work to use political economy insights to inform intervention design to overcome accountability failures?
