The politics of infrastructural projects :  a case for evidence-based policymaking 

 - Philadelphia :  Routledge,  March 2010 
<br/><br/> Many developing countries currently face tightening fiscal constraints as a result of the global financial crisis and associated reduction in both credit and demand. Policymarkers therefore have less fiscal space within which to undertake projects, so the opportunity cost of any misallocation of resources will be correspondingly higher. There is therefore an increasing need to rely more on evidence-based policymaking (EBPM). The is particularly so for large infrastructural projects, as these tend to be costly, and especially for transportation projects as these are particularly prone to result in sub-optimal outcomes. This paper examines the policy process for the implementation of the Jamaican Highway 2000, one of the largest and most costly infrastructure projects in Jamaica in recent years. A number of primary and secondary data sources were explored to ascertain the extent to which the decision to implement the project reflects a case for evidence-based decision-making in practice. This made it clear that the decision was taken at least partly on political grounds, largely in the absence of any supportive evidence, and on the basis of over-optimistic and unrealistic assumptions, and that this has created a number of serious, long-term challenges for Jamaica
