The city of Bogotá set out to reduce crime and increase state legitimacy by raising state presence on city streets: either increasing police time by two thirds, or delivering clean up and lighting services. In their new paper, Christopher Blattman and his co-authors find that these large and sustained increases in state presence have relatively modest effects on crime, violence, and state legitimacy. They conclude that there may be returns to a more focused approach: increasing and concentrating efforts on the places with the greatest need and least prior state presence.
