The use of public-private partnerships (PPPs) worldwide to facilitate private-sector participation in a variety of transportation infrastructure delivery tasks is growing. Tasks increasingly allocated to the private sector include the design, construction, operation, maintenance, and financing of large transportation facilities. Although academic literature on PPPs is burgeoning, there has been little empirical examination of the effects of private operation and maintenance of roads on road safety. We help to address that gap by constructing a large dataset on privately managed roads in Mexico.
