A working paper with Justin Sandefur, Sarah Dykstra and Amanda Glassman. Since 2001, an aid consortium known as Gavi has accounted for over half of vaccination expenditure in the 75 eligible countries with an initial per capita GNI below $1,000. Regression discontinuity (RD) estimates show aid significantly displaced other immunization efforts and failed to increase vaccination rates for diseases covered by cheap, existing vaccines. For some newer and more expensive vaccines, i.e., Hib and rotavirus, we found large effects on vaccination and limited fungibility, though statistical significance is not robust. These RD estimates apply to middle-income countries near Gavi's eligibility threshold, and cannot rule out differential effects for the poorest countries. There's a policy brief that's an easier read.
This is a report of the CGD Working Group on Publish What You Buy. Government contracts regarding the use of public property and finances should be published by default. Many jurisdictions already require that contracts be made public in response to requests for the information; some now publish contracts proactively. Doing so helps new entrants compete in the market for public contracts, helps governments model their projects on other successful examples, and allows citizens greater insight into how their taxes are being spent. This brief, summarizing the conclusions of the Working Group on Government Contract Publication, provides a practical outline for reaping the benefits of open contracts while addressing legitimate concerns about costs, collusion, privacy, commercial secrecy, and national security. There is the full paper, a brief, and editorials in The Guardian and The Wall Street Journal.
