We study how the management practices bureaucrats operate under correlate to the quantity of public services delivered, using data from the Nigerian Civil Service. We have hand-coded independent engineering assessments of 4700 project completion rates. We supplement this with a management survey in the bureaucracies responsible for these projects, building on Bloom and Van Reenen [2007]. Management practices matter: increasing bureaucrats’ autonomy is positively associated with completion rates, yet practices related to incentives/monitoring of bureaucrats are negatively associated with completion rates. Our evidence provides new insights on the importance of management in public bureaucracies in a developing country setting. JEL Classification: J33, O20
