The determinants of cost deviations and overruns in transport projects, an endogenous models approach
https://orcid.org/0000-0003-2910-5298
Abstract Cost deviations and overruns are a recurrent topic in the transport infrastructure literature. Even though there is a general trend towards a more frequent occurrence of overruns the main determinants of such phenomena are still not consensual. This paper analyses a dataset of 1091 transport projects developed by the Portuguese government (central, regional, and local) between 1980 and 2012. The methodology builds on existing approaches but provides a more ambitious (and innovate) approach towards the incorporation of exogenous determinants, examples being political, legal and regulatory, and economic ones. The analysis suggests that these exogenous variables that have been under-valuated in the existing literature, and that they do, indeed, play a relevant role in understanding cost deviations.
Highlights There is a major concern about cost deviation and overruns in Transport projects. This paper analyses a dataset of 1091 transport projects developed in Portugal. We go beyond literature, by using exogenous models in our analyses. Political, legal/regulatory, and economic variables are used to explain cost deviations. They play a relevant role in understanding cost deviations.
