Public investment efficiency in developing countries

Dabla-Norris et al. (2011) construct Public Investment Management Index (PIMI) that benchmarks the quality and efficiency of the investment process across 71 developing and emerging countries.

According to their findings, the 5 countries with the most efficient investment processes are middle-income (South Africa, Brazil, Colombia, Tunisia and Thailand), and the weakest performers (Belize, Congo-Brazzaville, Solomon Islands, Yemen, and the West Bank and Gaza).

Country efforts to “invest in the investment process” encompasses several aspects or stages – country capacity to carry out technically sound and non-politicised project appraisal and selection, appropriate mechanisms for implementation, oversight, and monitoring of investment projects, and ex post evaluation. We create sub-indices that aggregate indicators across these four stages of the investment process: project appraisal, selection, implementation, and evaluation. The first stage, project appraisal, ensures investments are chosen based on development policy priorities. The second stage captures the extent to which project selection is linked to the budget cycle – country experiences find opaque organisational arrangements result in chronic under-execution of investment budgets, rent seeking, and corruption. Project implementation covers a range of aspects, from timely budget execution and efficient procurement to sound internal budgetary monitoring and control. The last stage, ex post evaluation of projects compares the project’s costs with those established during project design.

We scored countries on each of the stages (each of the stages is made up of several individual components, 17 in total). The different components were scored and combined to construct the overall PIMI. A scale between 0 and 4 was used for each question (most data is qualitative), with a higher score reflecting better public investment management performance.

[…] In the current environment of abundant liquidity and search for yield, and the growing importance of BRICs as sources of foreign direct investment and aid, low-income countries have access to financing like never before. It will be important that they leverage it to close the infrastructure gap and increase growth. "Investing in the investment process" will ensure that the much-needed scaling-up of investment leads to future sustained prosperity rather than roads and bridges that lead to nowhere.
