Political turnover, electoral incentives and public inefficiencies: evidence from unfinished infrastructure projects in Brazil

Orientador(a): Claudio Ferraz

Public infrastructure projects like roads and schools have been regarded as drivers of development, yet developing democracies systematically fail to deliver such investments, and half-finished projects are a common issue. Using a novel database of over 75,000 small development projects in Brazil, we estimate that more than 40\% of projects that start are never completed. Employing a close races regression discontinuity design on Brazilian mayoral elections, we find that turnover negatively impacts the delivery of projects inherited in a construction stage, while causes positive responses on the delivery of more recent projects. We argue that our results are consistent with a theory linking project non-conclusion to electoral incentives, where inefficiencies on project procurement are driven by a credit-claim dynamics that disincentives the conclusion of works inherited from the opposition. Our findings highlight the importance of insulating policies from the electoral process in local politics.
