Multiple criteria decision analysis of public investment options: application to streetlighting renewal projects

The last global economic crisis set fiscal consolidation as one of the most relevant goals of economic policy. At the same time, efforts are necessary to increase economic growth rates, particularly by increasing quantity and quality of public investment. However, the lack of fiscal space and other impediments make these goals hard to attain. On the contrary, in many countries data show negative dynamics of quantity and quality of public investment. In terms of energy efficiency investment, trends are positive. However, the pace of investment significantly underperforms the goals set. We argue that one of the major reasons is the lack of financial innovation and project selection methodology. For this reason, projects have still been mainly financed under traditional procurement models. Surprisingly, most countries do not exploit the advantages of alternative models of financing which do not affect public debt level, significantly reduce fiscal deficits and reduce fiscal risks. This article argues that a multi-criteria approach used at the initial stages of project preparation increases the potential for project realisation and the overall quantity and quality. In order to provide empirical evidence, we use information on energy efficiency streetlighting projects and present a case of a traditional versus alternative financing models. Highlightsa need for a systematic approach when selecting optimal financing model is a must;a lack of financial innovation is one of the most critical impediments to a higher level of investment in revenue-generating projects common for the energy efficiency sector;alternative models of financing enable public investment increase without harming the fiscal position;a new methodology for selecting the most preferable model is presented;a policy mix should take more comprehensive stance towards complexity of public investment projects.
