Teachers in Tanzania are absent 23 percent of the time; doctors in Senegal spend an average of 39 minutes a day seeing patients; in Chad, 99 percent of non-wage public spending in health disappears before reaching the clinics.
These and other service delivery failures have been widely documented since the 2004 World Development Report, Making Services Work for Poor People.
But why do these failures persist? Because they represent a political equilibrium where politicians and service providers (teachers, doctors, bureaucrats) benefit from the status quo and will therefore resist attempts at improving services. For instance, teachers are often the campaign managers for local politicians. They work to get the politician elected, in return for which they get a job from which they can be absent. Powerful medical unions ensure that their members can work in the private sector and neglect their salaried government jobs. The losers are the poor, whose children don't learn to read and write, or get sick and die because the public clinic is empty.
