Scoring

Each institution is analyzed along three dimensions that reflect the key features of the given institution, resulting in a total of 45 dimensions. Three possible scores are assigned to each dimension (1: not met, 2: partially met, 3: fully met) and their average within an institution produces a score for that institution. PIMA scores are summarized in a chart that allows comparison with its comparators. In the chart, the further the away from the center, the higher the PIMA scores.

Institutional Design and Effectiveness

Another key feature of the PIMA is that it assesses both institutional design (“what is on paper”) and effectiveness (“what is in practice”) of a given country, because there is often a gap between the design of formal rules and how they are implemented in practice, due to capacity constraints among others.

Scores by Income Level

All countries, most notably emerging markets and low-income developing countries, have significant room to improve their infrastructure governance to increase effectiveness in public investment.
