We introduce a novel and simple diagnostic tool to improve the performance of public services (e.g. in health, education, utilities and transportation). We propose a method to compute performance/productivity ratios, which can be applied as soon as data on production units' outcomes and...

School accountability schemes require measures of school performance, and these measures are in practice often based on pupil test scores. It is well-known that insufficiently correcting these test scores for pupil characteristics may provide incentives for inefficient pupil selection. We show...
