This paper contributes to strengthening this evidence base providing better guidance to donors around how they can best facilitate private sector contributions to sustainable development outcomes, as envisaged in the Addis Ababa Action Agenda. It does this by illustrating firstly how donor support to the enabling environment for private sector development fits alongside, and underpins, other catalytic aid approaches. And secondly by highlighting how available data can (or, indeed, struggles to) inform decisions to maximise the impact of donors' catalytic interventions in different groups of developing countries.

Corruption is attracting a lot of attention around the world. The paper surveys and discusses issues related to the causes, consequences, and scope of corruption and possible corrective actions. It emphasizes the costs of corruption in terms of economic growth. It also emphasizes that the fight against corruption may not be cheap and cannot be independent from the reform of the state. If certain reforms are not made, corruption is likely to continue to be a problem regardless of actions directly aimed at curtailing it.

¿Cuáles son las principales causas y los costos de la corrupción? En este artículo se examinan estas cuestiones y se recomiendan formas concretas de mejorar las actividades de lucha contra la corrupción en los países en desarrollo y las economías en transición.
