2 The infrastructure gap and decentralization LUIS ALBERTO ANDRéS , DAN BILLER ,
Infrastructure gap: What is it? How to measure it? In order to assess the infrastructure gap, a country’s level of infrastructure provision needs first to be evaluated. This includes a diagnosis of coverage, quality, and efficiency of infrastructure services, and investments in infrastructure. It involves gathering existing data on access rates to the various infrastructure services. To the extent possible, the quality of service provision should also be appraised. In order to gage the realism of infrastructure service targets, a review of the historic level of investment in infrastructure through creation of a timeseries on actual public and private investment is also essential. In its simplest form, the actual gap is thus the difference between targets and baseline over a time period in which the gap is aimed to be filled.
