Gorkhali, S: Economic Analysis of Infrastructure Investments

Infrastructure plays a significant role in the economic development of a country. The role of infrastructure is even more important in developing countries that are ravaged by poverty and sluggish economic growth rates. The contribution of infrastructure to economic growth and poverty reduction has been established theoretically and empirically. Due to the inherent characteristics of infrastructure, including the huge amount of resources required for investment, the public sector still plays a pivotal role in the provision of infrastructure particularly in developing countries. Scarcity of resources demands that the allocation of resources to an infrastructure project needs to be based on the efficiency of its usage. However, due to difficulties in observing the Pareto efficiency criterion, compensation test criterion is chosen as the basis for economic analysis for finding an economically desirable resource allocation. Though an economic analysis is undertaken for resource allocation decisions particularly by the multinational development banks, decisions are often based on an incomplete analysis. While the changes in welfare of all affected individuals in a society need to be measured to assess the desirability of a project, the changes in welfare brought about through the project's environmental and socio-cultural effects are often ignored. Accordingly, this study is aimed at analysing the role of infrastructure in the development of a country and the consequences of discrepancies in assessing economic desirability in practice from its theoretical foundations. The results of the study show that while infrastructure is significant for the economic development of a country, there is a difference in the practice of economic analysis from its theoretical foundations. While it is necessary to include changes in welfare from project's impacts on both market and non-market goods, in practice the welfare effects from non-market goods are often ignored.
