Tóm tắt

 As a means to reduce delays in public works implementation, a number of Brazilian states have recently reformed their procurement rules allowing contractor price proposals to be assessed before the technical evaluation of submitted bids is undertaken (in a procedure known as inversao das fases). In order to evaluate the effects of such reform, this paper adopts a difference-in-differences methodology to compare the procurement performance of Sao Paulo state (a reformer state) and Minas Gerais' (a non-reformer state) largest water and sewage utility along three efficiency dimensions: (i) procurement process duration
  (ii) likelihood of complaint resolution litigation
  and (iii) prices paid to contractors. The analysis finds that the reform is associated with a 24 day reduction in the duration of procurement processes for large projects and a 7 percentage point drop in the likelihood of court challenges irrespective of project size. Although both effects are economically important, only the latter is statistical significant. Finally, the paper finds no evidence of an effect of the procurement reform on prices paid.
