Investing in public investment: an index of public investment efficiency

Pritchett (J Econ Growth 5:361?C384, 2000) convincingly argued that the difference between investment cost and capital value is of first-order empirical importance especially for developing countries where public investment is the primary source of investment. This paper constructs a public investment efficiency index that captures the institutional environment underpinning public investment management across four different stages: project appraisal, selection, implementation, and evaluation. Covering 71 countries, including 40 low-income countries, the index allows for benchmarking across regions and country groups and for nuanced policy-relevant analysis and identification of specific areas where reform efforts could be prioritized. Research applications are outlined.
