This volume provides a comprehensive review of the empirical evidence on corruption generated by recent laboratory and field experiments conducted by economists and political scientists. The first part of the volume reviews the evidence produced by laboratory experiments in relation to gender and cultural differences in corruption decision-making, as well as the effectiveness of different anti-corruption policies. This part concludes with an assessment of the external validity of corruption investigations relying on laboratory experiments. The second part of the volume reviews recent contributions to corruption research made through the use of field experiments. Special attention is given to advances in measuring corruption in the field, investigations of clientelism and vote-buying, and the role that information can play in the fight against corruption. A critical assessment of the effectiveness of top-down and bottom-up anti-corruption interventions completes this section. The volume concludes with important reflections on the role that behavioral and experimental economics can play in anti-corruption research and practice.

This paper presents unique evidence on health workers' career choices in Ethiopia. It shows that challenges like health workers' limited willingness to work in rural areas, as well as their likelihood to migrate abroad vary substantially and are correlated with background, motivation, and job satisfaction. Governments in Africa have identified human resources for health as a priority to improve health outcomes. This study is a valuable resource to better understand health worker choices and help toward the design of more effective human resource policies. This working paper was produced as part of the World Bank's Africa Region Health Systems for Outcomes (HSO) Program. The Program, funded by the World Bank, the Government of Norway, the Government of the United Kingdom and the Global Alliance for Vaccines and Immunization (GAVI), focuses on strengthening health systems in Africa to reach the poor and achieve tangible results related to Health, Nutrition and Population. The main pillars and focus of the program center on knowledge and capacity building related to Human Resources for Health, Health Financing, Pharmaceuticals, Governance and Service Delivery, and Infrastructure and ICT.
