== Abstract ==

The authors have assembled 19602012 infrastructure stock data from 145 countries to estimate the demand for infrastructure services in emerging markets and developing economies. This paper identifies that the required resource flows to satisfy new demand while maintaining service for existing infrastructure amounts to $836 billion or 6.1 percent of current gross domestic product per year over the period 201420. The annual infrastructure investment gap for emerging markets and developing economies is $452 billion per year, which implies that emerging markets and developing economies should almost double their current spending. The paper also estimates that half of the spending should be allocated to maintenance of existing assets. Acknowledging the challenges to compare infrastructure investment estimates across different methodologies, the authors recognize this result as a lower bound estimate and compare the results with others available in the literature.
